谷歌地图iOS sdk获取挖掘重叠坐标 [英] Google maps iOS sdk get tapped overlay coordinates

问题描述

我正在使用Google地图iOS sdk。
i当用户点击一个叠加层时想获得触摸点的坐标。

有这个委托方法：

   - （void）mapView：（GMSMapView *）mapView didTapAtCoordinate：（CLLocationCoordinate2D）coordinate 
  

但是当你点击一个覆盖层或一个标记时它不会被调用。

我可以通过程序调用它（但是坐标参数缺失 - 这就是我想要的..）？
或者从这个位置获取位置：

$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ map $ ）overlay

任何建议都很珍贵！

谢谢！

将UITapGestureRecognizer拖放到地图上，然后从触摸点提取坐标。您的didTapAtCoordinate和didTapAtOverlay将继续如前所述。

  UITapGestureRecognizer * touchTap = [[UITapGestureRecognizer alloc] initWithTarget：self action：@选择器（tapTouchTap :)]; 
 [self.view addGestureRecognizer：touchTap]; 
 
  - （void）tapTouchTap：（UITapGestureRecognizer *）touchGesture 
 {
 CGPoint point = [touchGesture locationInView：self.view]; 
 CLLocationCoordinate2D coord = [self.mapView.projection coordinateForPoint：point]; 
 NSLog（@％f％f，coord.latitude，coord.longitude）; 
}

您可能会丢失两段代码。
在头文件中采用GMSMapViewDelegate：

$ $ p $ @interface Map：UIViewController< GMSMapViewDelegate>


您还需要在您的viewDidLoad中设置委托：

  self.mapView.delegate = self; 
  

现在这个应该会为您启动：

<$ p

- （void）mapView：（GMSMapView *）mapView didTapAtCoordinate： coordinate.latitude，coordinate.longitude）;
}


i'm working with Google maps iOS sdk. i want to get the coordinates of the touched point when user taps an overlay.

there is this delegate method:

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate

but it's not called when you tap an overlay or a marker.

can i call it programmatically (but coordinate parameter is missing-that's what i want..)? or get location from this:

- (void) mapView: (GMSMapView *) mapView  didTapOverlay: (GMSOverlay *) overlay

any suggestion's precious!

thanks!

Just staple a UITapGestureRecognizer onto the map and then extract the coordinate from the touch point. Your didTapAtCoordinate and didTapAtOverlay will continue to fire as before.

  UITapGestureRecognizer *touchTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTouchTap:)];
  [self.view addGestureRecognizer:touchTap];

-(void)tapTouchTap:(UITapGestureRecognizer*)touchGesture
{
  CGPoint point = [touchGesture locationInView:self.view];
  CLLocationCoordinate2D coord = [self.mapView.projection coordinateForPoint:point];
  NSLog(@"%f %f", coord.latitude, coord.longitude);
}

You are likely missing two snippets of code. Adopt the GMSMapViewDelegate in your header file:

@interface Map : UIViewController <GMSMapViewDelegate>

You also need to set the delegate in your viewDidLoad:

self.mapView.delegate = self;

Now this should fire for you:

- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate
{
    NSLog(@"You tapped at %f,%f", coordinate.latitude, coordinate.longitude);
}
