I am a new to google map sdk for ios.I have added a map on a view.When I enter this mapView,I want to positioning myself.So I wrote :
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
longitude:151.2086
zoom:6];
_iMapView = [GMSMapView mapWithFrame:CGRectMake(0, 0, 320, 480) camera:camera];
self.iMapView.myLocationEnabled = YES;
self.iMapView.delegate=self;
GMSMarkerOptions *annotation = [[GMSMarkerOptions alloc] init];
annotation.position = CLLocationCoordinate2DMake(-33.8683, 151.2086);
annotation.title = #"Sydney";
annotation.snippet = #"Australia";
//annotation.infoWindowAnchor=CGPointMake(0.5, 0.5);
[self.iMapView addMarkerWithOptions:annotation];
//[self.view addSubview:self.iMapView];
self.view=self.iMapView;
but I find the mapView view in the coordinate(33.8683,151.2086),I just want to move the mapView to the wyposition. I also find google have no callback function reference to
self.iMapView.myLocationEnabled = YES;
thank you for you reply.
To animate/set the camera to your current position you first have to:
self.googleMapsView.myLocationEnabled = YES;
Then in the documentation of the GMSMapView header file you will find the following comment:
/**
* If My Location is enabled, reveals where the user location dot is being
* drawn. If it is disabled, or it is enabled but no location data is available,
* this will be nil. This property is observable using KVO.
*/
#property (nonatomic, strong, readonly) CLLocation *myLocation;
So you can setup a key value observer in your viewWillAppear Method and then you get your location update with the Location Manager of the GoogleMaps SDK.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// Implement here to check if already KVO is implemented.
...
[self.googleMapsView addObserver:self forKeyPath:#"myLocation" options:NSKeyValueObservingNew context: nil]
}
And then observe the property.
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
if ([keyPath isEqualToString:#"myLocation"] && [object isKindOfClass:[GMSMapView class]])
{
[self.googleMapsView animateToCameraPosition:[GMSCameraPosition cameraWithLatitude:self.googleMapsView.myLocation.coordinate.latitude
longitude:self.googleMapsView.myLocation.coordinate.longitude
zoom:self.googleMapsView.projection.zoom]];
}
}
Do not forget to deregister your observer in the viewWillDisappear.
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
// Implement here if the view has registered KVO
...
[self.googleMapsView removeObserver:self forKeyPath:#"myLocation"];
}
Best regards
NOTE: This answer is wrong, see Robert's answer.
The Google Maps SDK for iOS doesn't have any delegate to let you know when the device's position has changed.
You would need to use the CLLocationManager class yourself, to get the device's current position, and then update the map view.
UPDATE:
To update the map view from the new CLLocation provided by the location manager, you do something like this:
GMSMapView* mapView = ...;
CLLocation* location = ...;
GMSCameraPosition* camera = [GMSCameraPosition
cameraWithLatitude: location.coordinate.latitude
longitude: location.coordinate.longitude
zoom: 6];
mapView.camera = camera;
Or if you want the map view to animate to the new location, then use this:
[mapView animationToCameraPosition: camera];

I need to implement a login UI in my tvOS application, but I don't want to use UIAlertController for the text input. Instead of this I want to implement a text input UI similar to the iCloud Sign In in the Settings app without any additional UITextFields.
You can do it with a table view populated with some cells with embedded text fields.
These UITextField than becomes input responder like:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// my UITableViewCell extended with UITextField
TextFieldCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
[cell.textField becomeFirstResponder];
}
place text field on a view (If you dont wont to show it, place it out of borders)
in viewController code add inputAccesoryView method
When you need to show your input view - call [self.loginTextField becomeFirstResponder];
I found that input accesory view located in top right corner of standart input view, so code for it should look like this:
-(UIView *)inputAccessoryView {
if (!inputAccessoryView) {
CGRect accessFrame = CGRectMake(0, 0, 1920, 200);
inputAccessoryView = [[UIView alloc] initWithFrame:accessFrame];
titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(-500, -100, 1000, 100)];
titleLabel.font = [UIFont systemFontOfSize:59];
titleLabel.textColor = [UIColor whiteColor];
titleLabel.text = #"Login";
titleLabel.textAlignment = NSTextAlignmentCenter;
[inputAccessoryView addSubview:titleLabel];
descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(-500, 0, 1000, 100)];
descriptionLabel.font = [UIFont systemFontOfSize:29];
descriptionLabel.textColor = [UIColor whiteColor];
descriptionLabel.text = #"Enter your E-mail or Login";
descriptionLabel.textAlignment = NSTextAlignmentCenter;
[inputAccessoryView addSubview:descriptionLabel];
}
return inputAccessoryView;
}
It work for me.
How to set the initial focus in a HTML page using UIWebView. For example, below is the HTML page. If i load this in UIWebView, it shows from (0,0) coordinates of a HTML view. But i want to change the starting position as described in the below image. I tried to change the offset, but no use.
webView.scrollView.contentOffset = CGPointMake(100, 100).
You probably shouldn't hard code this because for one reason, it's hard-coded. If google, or whatever website you want to display alters their layout your positions will be obsolete. And you will have to resubmit your entire app just to off-set this.
My recommendation is use auto layout and 'scales page to fit' for the UIWebView.
But your code is accurate. Make sure you put it in webViewDidFinishLoad: or viewDidLoad and your UIWebViewDelegate & UIScrollViewDelegate are added to your header file and called in your implementation file :
self.webView.delegate = self;
self.webView.scrollView.delegate = self;
Place the UIWebView into a subview. A generic UIView will work.
When instantiating the UIWebView, give it screen bounds with a slightly lower width than the containing UIView. Weird, I know.
Set the UIWebView's contentOffset in the webViewDidFinishLoad method of your UIWebViewDelegate
The following code works for me, in Xcode 6.1.1. To test, just make this ViewController class the root view controller for your app:
import UIKit
class ViewController: UIViewController, UIWebViewDelegate {
override func loadView () {
let screenBounds : CGRect = UIScreen.mainScreen().bounds
var slimmerBounds : CGRect = UIScreen.mainScreen().bounds
slimmerBounds.size.width = slimmerBounds.size.width - 1
let webView = UIWebView(frame: slimmerBounds)
let url = NSURL (string: "http://google.com/")
let req = NSURLRequest(URL: url!)
webView.loadRequest(req)
webView.delegate = self;
let contentView = UIView(frame: screenBounds)
contentView.addSubview(webView)
self.view = contentView
}
func webViewDidFinishLoad(webView: UIWebView) {
webView.scrollView.contentOffset = CGPointMake(0, 100)
webView.bounds = UIScreen.mainScreen().bounds
}
}
By the way ... this will set the initial position of all URLs loaded into this Web view. If you only want to position the first page, you'll need to add some additional logic to webViewDidFinishLoad
I'm trying to do the following:
SKTransition *reveal = [SKTransition pushWithDirection:SKTransitionDirectionDown duration:0.5];
SKView *skv = (SKView *)self.view.window.rootViewController.view;
[self.view presentScene:skv.scene transition:reveal];
but it doesn't work, I get a SIGABRT Error. What can I use to get the same effect. I can use dismissViewController but then how do I use the pushWithDirection effect.
I'm not entirely sure why you want to push to the view controller. If you just want to transition to a new scene you can do this from within the scene, without going near the parent view controller:
YourScene *nextScene = [[YourScene alloc] initWithSize:self.size];
SKTransition *reveal = [SKTransition pushWithDirection:SKTransitionDirectionDown duration:3.0];
[self.view presentScene:nextScene transition:reveal];
If you do want to call this from the view controller you can add the view controller as a property in your scene:
#import "YourViewController.h"
#property (nonatomic,weak) YourViewController *viewController;
In your view controller when you set up your initial scene, assign the view controller to that attribute:
yourScene.viewController = self;
Then, from within the scene you can call methods on the view controller:
[viewController yourMethod];
which is:
//YourViewController.h
#import "YourScene.h"
...
-(void)yourMethod;
//YourViewController.m
...
-(void)yourMethod
{
YourScene *nextScene = [[YourScene alloc] initWithSize:self.size];
nextScene.viewController = self;
SKTransition *reveal = [SKTransition pushWithDirection:SKTransitionDirectionDown duration:3.0];
[yourSKView presentScene:nextScene transition:doors ];
}
How can I add "drop pin" and the dropping on above animation in Google Map iOS?
I can only find marker in SDK, and the appearAnimation property only provides pop up animation.
Use MKAnnotationView from MapKit. From the documentation on Using the Standard Annotation Views:
MKAnnotationView* aView = [[[MKAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:#"MyCustomAnnotation"] autorelease];
In the GMSMarker Class reference it says for the appearAnimation property:
Controls the animation used when this marker is placed on a GMSMapView (default kGMSMarkerAnimationNone, no animation).
Using the Google Maps SDK for iOS a marker can be made like this:
GMSMarker *startMarker = [GMSMarker markerWithPosition:#"NYC"];
startMarker.appearAnimation = kGMSMarkerAnimationPop;
startMarker.title = #"Start";
startMarker.snippet = #"My address";
startMarker.map = mapView;
If you set the title or snippet property of a Marker then the tooltip will show when tapped.
marker.title = #"Hello World";
and/or
marker.snippet = #"Hello Snippet";
For swift:
locationMarker.appearAnimation = kGMSMarkerAnimationPop
locationMarker.icon = UIImage(named: "testImage") as UIImage?
When I use the following code to insert a view on top of a split view, I am getting orientation problems.
Here is the code I use,
[window addSubview:aSplitViewController.view];
[window insertSubview:aViewController.view aboveSubview:aSplitViewController.view];
What happens here is that the view controller ( which contains labels and buttons) loads in landscape mode while its components load in portrait mode...
I feel that the window insertSubview is creating this problem because when I used [window addSubview:aViewController.view] the view is getting displayed properly in landscape mode with its components in landscape mode as well...
Here is the code which I feel is giving me the problem
In my App Delegate
- (void) makeSplitViewController {
NSMutableArray *controllers = [NSMutableArray arrayWithArray:tabBarController.viewControllers];
// First tabbbar item
// detail view
detailViewController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:nil];
UINavigationController *navDetailView = [[[UINavigationController alloc] initWithRootViewController:detailViewController] autorelease];
navDetailView.hidesBottomBarWhenPushed = YES;
// root view
rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain];
rootViewController.detailViewController = detailViewController;
rootViewController.navigationItem.title = #"List";
UINavigationController *navRootView = [[[UINavigationController alloc] initWithRootViewController:rootViewController] autorelease];
navRootView.hidesBottomBarWhenPushed = YES;
navRootView.navigationBar.barStyle = UIBarStyleBlackTranslucent;
splitViewController = [[UISplitViewController alloc] init];
splitViewController.tabBarItem.title = #"Face Sheet";
splitViewController.tabBarItem.image = [UIImage imageNamed:#"gear1.png"];
splitViewController.navigationItem.title = #"Face Sheet";
splitViewController.viewControllers = [NSArray arrayWithObjects:navRootView, navDetailView, nil];
splitViewController.delegate = detailViewController;
splitViewController.hidesBottomBarWhenPushed = YES;
[controllers addObject:splitViewController];
// Second tabbbar item
scoreViewController = [[ScoreCardViewController alloc] initWithNibName:#"TableViewController" bundle:nil];
scoreViewController.tabBarItem.title = #"Score Card";
scoreViewController.tabBarItem.image = [UIImage imageNamed:#"gear1.png"];
scoreViewController.navigationItem.title = #"Score Card";
[controllers addObject:scoreViewController];
tabBarController.viewControllers = controllers;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Create tabbar
tabBarController = [[UITabBarController alloc] init];
//tabBarController.delegate = self;
// Set window
[window addSubview:splashController.view];
[window insertSubview:tabBarController.view belowSubview:splashController.view];
[self.window makeKeyAndVisible];
application.statusBarOrientation = UIInterfaceOrientationLandscapeRight;
return YES;
}
and here is the code in my SplashScreenView
- (IBAction) proceedButtonClick:(id)sender
{
// Initialize loginpopview
PhysicianLoginViewController *loginViewController = [[PhysicianLoginViewController alloc] init];
popOverController = [[UIPopoverController alloc] initWithContentViewController:loginViewController];
popOverController.popoverContentSize = CGSizeMake(350, 200);
popOverController.delegate = self;
// Set a notification to dismiss it later
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(loginViewControllerDone:) name:#"loginViewControllerDone" object:popOverController.contentViewController];
// Present popover
if ([popOverController isPopoverVisible])
{
[popOverController dismissPopoverAnimated:YES];
}
else
{
[popOverController presentPopoverFromRect:CGRectMake(485, 600, 100, 100) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
}
}
// Dismiss popview controller and setup the tabbar
- (void)loginViewControllerDone:(NSNotification *)notification
{
[[NSNotificationCenter defaultCenter] removeObserver:self];
// Button in content view controller was tapped, dismiss popover...
[self.popOverController dismissPopoverAnimated:YES];
// remove subview
[self.view removeFromSuperview];
// set tabbar
i3EAppDelegate *appDelegate = (i3EAppDelegate *) [[UIApplication sharedApplication]delegate];
[appDelegate makeSplitViewController];
}
It would be great if someone could point out where I am going wrong. I have been stuck with this problem for quite a few days and I have tried everything that comes to my mind...
Your problem is that the rotation handling of UIWindow and UIViewController just isn't designed to work that way. Quoth the documentation:
In an iOS application, the window object does much of the work associated with changing the current orientation. However, it works in conjunction with the application’s view controllers to determine whether an orientation change should occur at all, and if so, what additional methods should be called to respond to the change. Specifically, it works with the view controller whose root view was most recently added to, or presented in, the window. In other words, the window object works only with the frontmost view controller whose view was displayed using one of the mechanisms described in “Presenting a View Controller’s View.”
This paragraph is somewhat vague and contradictory (is it the most recently added view controller, or the controller for the topmost view?), and in practice doesn't seem to necessarily match observations. The bottom line is that adding multiple views to a UIWindow will screw up the automatic rotation handling.
You should change your code to use presentModalViewController:animated: (maybe with modalPresentationStyle set to UIModalPresentationFormSheet) or a UIPopoverController instead of adding multiple subviews to the window.
Try:
[aViewController.view setAutoresizingMask:UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight];
