Ios Map：获取经度和纬度 [英] Ios Map: Getting latitude and longitude

问题描述

我试图在用户触摸（点击）ios Map地点时读取经度和纬度我希望得到特定的（用户点击位置）放置纬度和经度点。
（对于（e.x），如果用户触摸ios总部意味着我想显示ios总部位置经度和纬度点）。我怎样才能做到这一点。任何人都可以帮我解决这个问题。

Am trying to read the longitude and latitude when the user touch (tap) on the ios Map place i want to get that particular (user tapping place) place latitude and longitude points. (for (e.x) if the user touch the ios head office means i want to show ios head office place longitude and latitude points). How can i do this. Any one can help me to solve this issue.

推荐答案

覆盖触摸处理程序（ touchesBegan 或 UITapGestureRecognizer ）然后使用
- （CLLocationCoordinate2D）convertPoint：（CGPoint）指向CoordinateFromView :( UIView *）视图 in MKMapView ，类引用这里。然后使用符合 MKAnnotation 协议的类，向地图添加适当的注释，例如 MKPinAnnotationView 。

Override a touch handler (touchesBegan or UITapGestureRecognizer) and then use - (CLLocationCoordinate2D)convertPoint:(CGPoint)point toCoordinateFromView:(UIView *)view in MKMapView, class reference here. Then add an appropriate annotation to the map using a class conforming to the MKAnnotation protocol, e.g. MKPinAnnotationView.

因此，示例触摸处理程序方法如下所示：

So an example touch handler method would look something like:

-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event 
{ 
    CGPoint pt = [[touches  anyObject]locationInView:self.mapView];  
    CLLocationCoordinate2D latLong = [self.mapView convertPoint:pt toCoordinateFromView:self.mapView]; 
    //add code here for annotation 
}

然后添加注释 - 本教程 http://www.raywenderlich.com/21365 / introduction-to-mapkit-in-ios-6-tutorial 应该可以帮助你 - 在同一个网站上也有一个iOS5版本。

Then add the annotation - this tutorial http://www.raywenderlich.com/21365/introduction-to-mapkit-in-ios-6-tutorial should help you with that- there's an iOS5 version on the same site as well.
