Anyone else experiencing this? I'm using the latest Google Maps SDK for iOS. This is what I have in the didTapInfoWindowOfMarker method :
- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(id<GMSMarker>)marker {
NSLog(#"yes");
}
Not getting any response in my output.
Sounds like you didn't add delegate and protocol for your GMSMapView object, something like:
mapView_.delegate = self;
in loadView method.
So, the full - (void)loadViewand delegate method should be:
#interface ViewController () <GMSMapViewDelegate> // Add this if you haven't
{
id<GMSMarker> myMarker;
}
- (void)loadView {
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
longitude:151.2086
zoom:6];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
mapView_.delegate = self; // This sets the delegate for map view
self.view = mapView_;
}
- (void)mapView:(GMSMapView *)mapView didTapInfoWindowOfMarker:(id<GMSMarker>)marker {
NSLog(#"yes"); // And now this should work.
}

I have a custom UIStoryboardSegue that works as desired in iOS12.*.
One of the destination view controller is a UITabbarController: for each tab, I have a controller embedded in a navigation controller.
Unfortunately, for iOS13.*, this does not work well: the view controller lifecycle is broken, and no call the viewXXXAppear() nor the willTransition() methods are no longer issued.
It looks like makeKeyAndVisible() has no effect?!
See at the bottom how the screen UI is puzzled below without viewWillAppear() being called.
An horrible temporary workaround
I had to pull my hairs but, I have found a fix which I make public (I had to add a navigation controller on the fly).
This messes the vc hierarchy: do you have a better solution?
public class AladdinReplaceRootViewControllerSegue: UIStoryboardSegue {
override public func perform() {
guard let window = UIApplication.shared.delegate?.window as? UIWindow,
let sourceView = source.view,
let destinationView = destination.view else {
super.perform()
return
}
let screenWidth = UIScreen.main.bounds.size.width
let screenHeight = UIScreen.main.bounds.size.height
destinationView.frame = CGRect(x: 0, y: 0, width: screenWidth, height: screenHeight)
window.insertSubview(destinationView, aboveSubview: sourceView)
// **My fix**
if #available(iOS 13,*) {
// I introduced an invisible navigation controller starting in iOS13 otherwise, my controller attached to the tabbar thru a navigation, dont work correctly, no viewXAppearis called.
let navigationController = UINavigationController.init(rootViewController: self.destination)
navigationController.isNavigationBarHidden = true
window.rootViewController = navigationController
}
else {
window.rootViewController = self.destination
}
window.makeKeyAndVisible()
}
}
I found a solution thanks to Unbalanced calls to begin/end appearance transitions with custom segue
What happens here is that the creation and attaching of the destination view controller happens twice, and the first one happens too soon.
So what you need to do is:
public class AladdinReplaceRootViewControllerSegue: UIStoryboardSegue {
override public func perform() {
guard let window = UIApplication.shared.delegate?.window as? UIWindow,
let sourceView = source.view,
let destinationView = destination.view else {
super.perform()
return
}
let screenWidth = UIScreen.main.bounds.size.width
let screenHeight = UIScreen.main.bounds.size.height
let mock = createMockView(view: desination.view)
window.insertSubview(mock, aboveSubview: sourceView)
//DO SOME ANIMATION HERE< MIGHT NEED TO DO mock.alpha = 0
//after the animation is done:
window.rootViewController = self.destination
mock.removeFromSuperview()
}
func createMockView(view: UIView) -> UIImageView {
UIGraphicsBeginImageContextWithOptions(view.frame.size, true, UIScreen.main.scale)
view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
let image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return UIImageView(image: image)
}
}
I had a similar problem on iOS 13 when performing a custom storyboard segue that replaces the rootViewController. The original code looked like this:
#interface CustomSegue : UIStoryboardSegue
#end
#implementation CustomSegue
- (void)perform {
AppDelegate* appDelegate = (AppDelegate*)[[UIApplication sharedApplication] delegate];
UIViewController *destination = (UIViewController *) self.destinationViewController;
[destination.view removeFromSuperview];
[appDelegate.window addSubview:destination.view];
appDelegate.window.rootViewController = destination;
}
#end
Removing the line [appDelegate.window addSubview:destination]; fixed the problem to me. Apparanently, it was unnecessary to add the new VC's view as a subview to the window. It did the job correctly even after removing that line, and it also fixed the error message "unbalanced calls to begin/end appearance transitions".
I've asked a similar question before with android and now struggling with the same method in iOS. I have build a iOS application using UIwebview. how do I allow the web view to access the camera here is my code below
#import "ViewController.h"
#define YourURL #"https://XXXXXXXXXXX"
#interface ViewController ()<UIWebViewDelegate>
#property (nonatomic,strong)UIWebView *webView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
self.webView.scrollView.frame =self.webView.frame;
_webView.backgroundColor = [UIColor grayColor];
_webView = [[UIWebView alloc]initWithFrame:CGRectMake(0, 20, self.view.bounds.size.width, self.view.bounds.size.height-20)];
_webView.delegate = self;
if ([[[[NSUserDefaults standardUserDefaults]dictionaryRepresentation]allKeys]containsObject:#"cookie"]) {
NSArray *cookies =[[NSUserDefaults standardUserDefaults] objectForKey:#"cookie"];
NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
[cookieProperties setObject:[cookies objectAtIndex:0] forKey:NSHTTPCookieName];
[cookieProperties setObject:[cookies objectAtIndex:1] forKey:NSHTTPCookieValue];
[cookieProperties setObject:[cookies objectAtIndex:3] forKey:NSHTTPCookieDomain];
[cookieProperties setObject:[cookies objectAtIndex:4] forKey:NSHTTPCookiePath];
NSHTTPCookie *cookieuser = [NSHTTPCookie cookieWithProperties:cookieProperties];
[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookieuser];
}
NSURLRequest *req = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",YourURL]]];
_webView.scalesPageToFit = YES;
[ self.webView loadRequest:req];
[self.view addSubview:self.webView];
}
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:YES];
}
- (void)webViewDidStartLoad:(UIWebView *)webView{
}
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSArray *nCookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
NSHTTPCookie *cookie;
for (id c in nCookies)
{
if ([c isKindOfClass:[NSHTTPCookie class]])
{
cookie=(NSHTTPCookie *)c;
if ([cookie.name isEqualToString:#"PHPSESSID"]) {
NSNumber *sessionOnly = [NSNumber numberWithBool:cookie.sessionOnly];
NSNumber *isSecure = [NSNumber numberWithBool:cookie.isSecure];
NSArray *cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure, nil];
[[NSUserDefaults standardUserDefaults] setObject:cookies forKey:#"cookie"];
break;
}
}
}
}
-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error{
NSLog(#"--------------%#",error);
}
#end
I have tried this but did not succeed gave me an error access camera from uiwebview?

thank you in advance
I enabled myLocation and myLocationButton,
but it not showing on my view.
And I try log _mapView.myLocation it's nil.
I need to showing myLocation dot and myLocationButton.
Have some one can help me, thanks!

I've subclass UINavigationController like this:
#implementation BaseNavigationController

// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor colorWithRed:0.95 green:0.95 blue:0.95 alpha:1];

if (self.viewControllers.count) {
viewController.hidesBottomBarWhenPushed = YES;
}
[super pushViewController:viewController animated:animated];
}
And also I've a subclass of UIViewController like this:
#implementation BaseViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.tabBarController.tabBar.translucent = NO;
self.navigationController.navigationBar.translucent = NO;
self.view.backgroundColor = [UIColor colorWithRed:0.95 green:0.95 blue:0.95 alpha:1];
}
- (UIStatusBarStyle)preferredStatusBarStyle {
return UIStatusBarStyleDefault;
}
All my view controller are inheriting the baseViewController and all my navigation controller are inheriting the baseNavigationController.
UITabBarViewController -> BaseNavigationController -> BaseViewController
The issue is sometimes when my application is back from background and tap a cell (UITableView or UICollectionView), pushViewController do not work, and the app get stuck.Or sometimes only navigation bar pushed to next view controller,shows next view controller's title and the app also get stuck.The next view controller's viewDidLoad method is called.
I've worried for a week and I do not know why this is happened,so please help me to fix this odd issue.
Not 100% get this issue ,only sometimes.Thank you.
I'm trying to load google maps view in iOS following the guide here
I created a new viewController for the map view called iptechMapViewController.h , iptechMapViewController.m and iptechMapViewController.xib
Here is the code in iptechMapViewController.m :
#import "iptechMapViewController.h"
#import <GoogleMaps/GoogleMaps.h>
#interface iptechMapViewController ()
{
GMSMapView *mapView_;
}
#end
#implementation iptechMapViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)loadView
{
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
longitude:151.2086
zoom:6];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
self.view = mapView_;
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.8683, 151.2086);
marker.title = #"Sydney";
marker.snippet = #"Australia";
marker.map = mapView_;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
Then in another view controller named iptechFlipsideViewController.m I'm trying to show the iptechMapViewController as follows:
- (IBAction)showMap:(id)sender
{
iptechMapViewController *controller = [[iptechMapViewController alloc] initWithNibName:#"iptechMapViewController" bundle:nil];
[self.view addSubview:controller.view];
}
But after clicking the showMap button which is connected to the IBAction showMap, and after iOS asks permission to access my location alert appears and I touch OK, after that nothing shows up and in the console I get the following error"
Failed to make complete framebuffer object 8cd6
Thanks
Passing CGRectZero to mapWithFrame only works if the map view is the root view controller's root view - in which case it is resized to fit the screen. In your case since the map is a subview, you will need to specify a size when creating the map view.
