How can i make the font to bold
[cell.itemContentWebView loadHTMLString:[NSString stringWithFormat:#"<div style='font-family:-apple-system','HelveticaNeue-Bold; style='font-size:24px;'>%#",object.title] baseURL:nil];
Rafay for your question
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
//Font size
int fontSize = 80;
NSString *jsString = [[NSString alloc] initWithFormat:#"document.getElementsByTagName('body')[0].style.webkitTextSizeAdjust= '%d%%'", fontSize];
[webview stringByEvaluatingJavaScriptFromString:jsString];
//Font Family Style - Bold
NSString *jsWebViewFontFamilyString = [[NSString alloc] initWithFormat:#"document.getElementsByTagName('body')[0].style.fontFamily = 'HelveticaNeue-Bold'"];
[webview stringByEvaluatingJavaScriptFromString:jsWebViewFontFamilyString];
//Font Color or web view text color
[webview stringByEvaluatingJavaScriptFromString:#"document.getElementsByTagName('body')[0].style.color = 'Green'"];
}
Just prefix a tag to your string before loading into the webView.
NSString *body = [plist objectForKey:#"foo"];
NSString *htmlString =
[NSString stringWithFormat:#"<font face='GothamRounded-Bold' size='3'>%#", body];
[webView loadHTMLString:htmlString baseURL:nil];

I have a UIWebView that is always smaller than the device's screen. Whatever I tried, it just won't scale the website to fit its bounds.
Here is my code:
self.webView = [[UIWebView alloc] initWithFrame:
CGRectMake(.08 * width, .18 * height, .84 * width, .74 * height)];
self.webView.delegate = self;
self.webView.scrollView.delegate = self;
self.webView.scrollView.scrollEnabled = NO;
self.webView.scalesPageToFit = YES;
NSString *urlAddress = #"https://number26.de/app-tutorial/dist/new-feature-invite.html";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
[self.view.window addSubview:self.webView];
That is how the result looks like:
And this is how it SHOULD look like (Google Chrome / Dev mode):
okey, this is my code
- (void)viewDidLoad {
[super viewDidLoad];
self.webView = [[UIWebView alloc] init];
self.webView.frame = CGRectMake(.08 * self.view.frame.size.width, .18 * self.view.frame.size.height, .84 * self.view.frame.size.width, .74 * self.view.frame.size.height);
self.webView.delegate = self;
self.webView.scrollView.delegate = self;
self.webView.scrollView.scrollEnabled = NO;
NSString *urlAddress = #"https://s.number26.de/app-tutorial/dist/new-feature-invite.html";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
[self.view addSubview:self.webView];
self.webView.scalesPageToFit = YES;
}
-(void)webViewDidFinishLoad:(UIWebView *)webView {
[self scaleToFit];
}
-(void)scaleToFit
{
if ([self.webView respondsToSelector:#selector(scrollView)])
{
UIScrollView *scroll=[self.webView scrollView];
float zoom=self.webView .bounds.size.width/scroll.contentSize.width;
[scroll setZoomScale:zoom animated:YES];
}
}
and see full website in webView. ]
add this code
-(void)webViewDidFinishLoad:(UIWebView *)webView {
[self scaleToFit];
}
-(void)scaleToFit
{
if ([self.webView respondsToSelector:#selector(scrollView)])
{
UIScrollView *scroll=[self.webView scrollView];
float zoom=self.webView .bounds.size.width/scroll.contentSize.width;
[scroll setZoomScale:zoom animated:YES];
}
}
My main goal here is to achieve an effect like Readability or Safari's Reader service where the main content of the webpage is converted to text. I don't actually want to display any images, just get all the webpage's important text. I am currently using some pretty long self-built code to parse the webpage for the s to find out what the heading may look like, and I am also parsing the s that I hope contain the majority of the page's content.
-(void)interpretAndDisplay {
NSURL *URL = [NSURL URLWithString:self.url];
NSData *data = [NSData dataWithContentsOfURL:URL];
NSString *html = [NSString stringWithUTF8String:[data bytes]];
//Getting the H1s
NSMutableArray *h1Full = [[NSMutableArray alloc] init];
h1Full = [self stringsBetweenString:#"<h1" andString:#">" andText:html];
if ([h1Full count] > 0) {
NSMutableArray *h1Content = [[NSMutableArray alloc] init];
h1Content = [self stringsBetweenString:[NSString stringWithFormat:#"<h1%#>",[h1Full firstObject]] andString:#"</h1>" andText:html];
NSMutableArray *h1Sanitize = [[NSMutableArray alloc] init];
h1Sanitize = [self stringsBetweenString:#"<" andString:#">" andText:html];
if ([h1Content count] > 0) {
NSString *finalTitle = [h1Content firstObject];
for (int i = 0; i < [h1Sanitize count]; i++) {
NSString *toRemove = [NSString stringWithFormat:#"<%#>",[h1Sanitize objectAtIndex:i]];
finalTitle = [finalTitle stringByReplacingOccurrencesOfString:toRemove withString:#""];
finalTitle = [finalTitle stringByReplacingOccurrencesOfString:#"\n" withString:#""];
}
finalTitle = [self sanitizeString:finalTitle];
[self.titleLabel setText:finalTitle];
}
}
//Now for the body!
NSMutableArray *pTag = [[NSMutableArray alloc] init];
pTag = [self stringsBetweenString:#"<p" andString:#">" andText:html];
if ([pTag count] > 0) {
NSMutableArray *pContent = [[NSMutableArray alloc] init];

NSMutableArray *pSanitize = [[NSMutableArray alloc] init];
pSanitize = [self stringsBetweenString:#"<" andString:#">" andText:html];
if ([pContent count] > 0) {
for (int i = 0; i < [pContent count]; i++) {
NSString *pToEdit = [pContent objectAtIndex:i];
for (int i = 0; i < [pSanitize count]; i++) {
NSString *toRemove = [NSString stringWithFormat:#"<%#>",[pSanitize objectAtIndex:i]];
pToEdit = [pToEdit stringByReplacingOccurrencesOfString:toRemove withString:#""];
}
[pContent replaceObjectAtIndex:i withObject:pToEdit];
}
for (int i = 0; i < [pContent count]; i++) {
NSString *pToEdit = [pContent objectAtIndex:i];
pToEdit = [pToEdit stringByReplacingOccurrencesOfString:#"\n" withString:#""];
[pContent replaceObjectAtIndex:i withObject:pToEdit];
}
NSString *finalBody = #"";
for (int i = 0; i < [pContent count]; i++) {
if ([finalBody isEqualToString:#""]) {
finalBody = [NSString stringWithFormat:#"%#",[pContent objectAtIndex:i]];
}
else {
finalBody = [NSString stringWithFormat:#"%#\n\n%#",finalBody,[pContent objectAtIndex:i]];
}
}
finalBody = [self sanitizeString:finalBody];
[self.textLabel setText:finalBody];
}
}
}
The above code extracts all of the elements just fine and sanitizes them with a method that I created, but the problem is that just analyzing the P tags sometimes completely fails to simplify the content, and analyzing all possible content tags could mess with the content's order and layout.
Is there a better way or some framework that converts all the text into a nice string?
EDIT
Searching around, I found a Boilerpipe project that can extract text extremely easily (https://github.com/k-bx/boilerpipe/wiki/QuickStart). It looks as easy as this: String text= ArticleExtractor.INSTANCE.getText(url);
Can I do this on Objective C?
Edit 2
It appears that there is a boilerpipe API, but this has limited requests. I am mostly looking for a user-side solution.
Reggie is not the most tolerant approach in my opinion.
I'd try to find an existent open source (i.e. https://github.com/Kerrick/readability-js) and use WebKit to inject JS into a web page once loaded.
After that you can inject another JS, extracting the processed content (using the appropriate class from the source)
Then, using JavaScriptCore you can pass div's content to Objective-C (JS offers many ways of doing that)
I'm currently creating and returning a custom view with the google maps ios SDK by setting delegate to self and using the following code.
#pragma mark - GMSMapViewDelegate
-(UIView*)mapView:(GMSMapView *)mapView markerInfoWindow:(id<GMSMarker>)marker {
int popupWidth = 200;
int contentWidth = 180;
int contentPad = 10;

int popupBottomPadding = 16;
int popupContentHeight = popupHeight - popupBottomPadding;
int buttonHeight = 30;
UIView *outerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupHeight)];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, popupWidth, popupContentHeight)];
[view setBackgroundColor:[UIColor whiteColor]];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 0, contentWidth, 22)];
[titleLabel setFont:[UIFont systemFontOfSize:17.0]];
titleLabel.text = [marker title];
UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(contentPad, 24, contentWidth, 20)];
[descriptionLabel setFont:[UIFont systemFontOfSize:11.0]];
descriptionLabel.text = [marker snippet];
[view addSubview:titleLabel];
[view addSubview:descriptionLabel];
UIButton *directionButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
directionButton.frame = CGRectMake(contentPad, 45, contentWidth, buttonHeight);
[directionButton setTitle:#"Directions" forState:UIControlStateNormal];
[directionButton addTarget:self action:#selector(directionsPressed) forControlEvents:UIControlEventTouchDown];
UIButton *viewLocationButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[viewLocationButton addTarget:self action:#selector(viewLocationPressed) forControlEvents:UIControlEventTouchUpInside];
[viewLocationButton setTitle:#"View Location" forState:UIControlStateNormal];
viewLocationButton.frame = CGRectMake(contentPad, 80, contentWidth, buttonHeight);
// handle bottom dealio
UIImage *bottomImage = [UIImage imageNamed:#"map-pointer-bottom"];
UIImageView *bottomView = [[UIImageView alloc] initWithFrame:CGRectMake((popupWidth / 2) - (bottomImage.size.width / 2), (popupContentHeight), bottomImage.size.width, bottomImage.size.height)];
[bottomView setImage:bottomImage];
[outerView addSubview:view];
[outerView addSubview:bottomView];
[outerView addSubview:directionButton];
[outerView addSubview:viewLocationButton];
ListItem *li = (ListItem*)[marker userData];
self.currentItem = li;
NSLog(#"List Item %# - %#", li.type, li.typeid);
return outerView;
}
-(void)directionsPressed {
NSLog(#"Directions Pressed");
}
-(void)viewLocationPressed {
NSLog(#"Location View Pressed");
}
- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(id<GMSMarker>)marker {
NSLog(#"Tap Captured");
}
The didTapWindowOfMarker is being fired when i tap the custom view, but neither of the target methods for the buttons are being fired.
Any ideas for why this might be?
Possibly, as mentioned officially in documentation of Google Maps Android API, the below restriction regarding infowindows applies to Google Maps iOS SDK also :
Info window is not a live View, rather the view is rendered as an image onto the map. As a result, any listeners you set on the view are disregarded and you cannot distinguish between click events on various parts of the view. You are advised not to place interactive components — such as buttons, checkboxes, or text inputs — within your custom info window.
So basically clicking on any part of the infowindow will trigger only "didTapWindowOfMarker"
Swift 3.0 Solution
//empty the default infowindow
func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
return UIView()
}
// reset custom infowindow whenever marker is tapped
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
customInfoView.removeFromSuperview()
// customInfoView.button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
self.view.addSubview(customInfoView)
// Remember to return false
// so marker event is still handled by delegate
return false
}
// let the custom infowindow follows the camera
func mapView(_ mapView: GMSMapView, didChange position: GMSCameraPosition) {
if (locationMarker != nil){
let location = locationMarker.position
customInfoView.center = mapView.projection.point(for: location)
}
}
// take care of the close event
func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
customInfoView.removeFromSuperview()
}
and make outlet of this view(customInfoWindow) in same controller which has mapView.
I got the idea from this link thanks to this developer Custom and interactive googlemaps(IOS SDK) infowindow
I have a UView and I'm adding a delegate to the view so that a UIButton calls a selector. For the google map, I don't do anything when I call
- (void) mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(GMSMarker *)marker;
However, I set my infowindow (my custom view) delegate to self, and call all my actions when I press the button that's linked to the selector.
UPDATE:
Here is the code I use in order to detect tap on buttons added to my infoWindows. I create a custom infoWindow with 2 fake buttons (they could actually replaced by images because they won't trigger any action) and I add a completely transparent overlay with 2 real buttons over the infoWindow. These buttons will trigger the actions.
And I use a few delegate methods or KVC in order to move the overlay when the infoWindow itself is moved.

FORMER POST:
Have a look at this thread and specifically at #9, should be helpful
https://code.google.com/p/gmaps-api-issues/issues/detail?id=4961
1)Create one subview which you want to show in infoWindow.
2)Set frame of subview equals to frame of infoWindow view.
[subView setFrame:infoview.frame];
subView = [[[NSBundle mainBundle] loadNibNamed:#"viewName" owner:self options:nil] objectAtIndex:0];
[self.mapview addSubview:subView];
How can I display multiple markers on the Google Map in iOS?
I used the following approach, but it didn't work.
for (int i = 0; i < [array count]; i++)
{
pointsToUse[i] = CLLocationCoordinate2DMake([[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:0] floatValue],[[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:1] floatValue]);
[_map animateToLocation:pointsToUse[i]];
GMSMarkerOptions *options = [[GMSMarkerOptions alloc] init];
options.position = pointsToUse[i];
[_map animateToLocation:pointsToUse[i]];
[_map addMarkerWithOptions:options];
}
You're using [array objectAtIndex:0] (in two places), when I think you should probably be using [array objectAtIndex:i]?
Also, you probably don't need the calls to animateToLocation?
I tried your code. This seems to work fine. Just delete the object at index 0 after passing it values to pointsToUse.
NSMutableArray *array = [NSMutableArray arrayWithObjects:#"12.981902,80.266333",#"12.982902,80.266363", nil];
CLLocationCoordinate2D pointsToUse[5];
for (int i = 0; i < [array Size]; i++)
{
pointsToUse[i] = CLLocationCoordinate2DMake([[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:0] floatValue],[[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:1] floatValue]);
[array removeObjectAtIndex:0];
GMSMarkerOptions *options = [[GMSMarkerOptions alloc] init];
options.position = pointsToUse[i];
[mapView_ animateToLocation:pointsToUse[i]];
[mapView_ addMarkerWithOptions:options];
}
Try this:
-(void)plotMutliplePinsonMap
{
mapView_ = [[GMSMapView alloc]initWithFrame:CGRectMake(0, 96, 320, 450)];
for(int i=0;i<[arrTobeShown count];i++)
{
double_lat = [[[arrTobeShown objectAtIndex:i]valueForKey:#"latitude"] doubleValue];
double_long = [[[arrTobeShown objectAtIndex:i]valueForKey:#"longitude"] doubleValue];
GMSMarker *mkr = [[GMSMarker alloc] init];
if (double_lat !=0 && double_long!=0)
{
[mkr setPosition:CLLocationCoordinate2DMake(double_lat, double_long)];
[mkr setTitle:[[arrTobeShown objectAtIndex:i] valueForKey:#"name"]];
[mkr setSnippet:[[arrTobeShown objectAtIndex:i] valueForKey:#"address"]];
[mkr setMap:mapView_];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:double_lat longitude:double_long zoom:5];
mapView_.camera=camera;
}
}
[self.view addSubview:mapView_];
[mapView_ setHidden:YES];
[self.view layoutIfNeeded];
}
Yes both of you are correct. According to your suggestions I changed the code and it works.
But the problem is, I set the zoom and the zoom is fixed. If the two locations are far, I can't see both locations on one screen ( i need to pinch to see both). How can I see both locations at the same time?
My code is shown below.
-(void) displayMapwithPositionfortheArray:(NSMutableArray*) array
{
CLLocationCoordinate2D firstPoint = CLLocationCoordinate2DMake([[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:0] floatValue],[[[[array objectAtIndex:0] componentsSeparatedByString:#","] objectAtIndex:1] floatValue]);
GMSCameraPosition *currloc = [GMSCameraPosition cameraWithLatitude:firstPoint.latitude
longitude:firstPoint.longitude
zoom:8
bearing:0
viewingAngle:45];
_map = [GMSMapView mapWithFrame:CGRectZero camera:currloc];
_map.myLocationEnabled = YES;
_map.frame = CGRectMake(0, heightOffset, self.view.frame.size.width, self.view.frame.size.height - heightOffset);
[self.view addSubview:_map];
CLLocationCoordinate2D pointsToUse[[array count]];
for (int i = 0; i < [array count]; i++)
{
pointsToUse[i] = CLLocationCoordinate2DMake([[[[array objectAtIndex:i] componentsSeparatedByString:#","] objectAtIndex:0] floatValue],[[[[array objectAtIndex:i] componentsSeparatedByString:#","] objectAtIndex:1] floatValue]);
GMSMarkerOptions *options = [[GMSMarkerOptions alloc] init];
options.position = pointsToUse[i];
[_map addMarkerWithOptions:options];
}
}
