在iPhone中从我的应用打开本机地图应用

我想通过单击按钮从我的应用程序打开本机地图应用程序。我如何才能做到这一点？

看看下面的代码，它将满足您的需要

NSString *title = @"any title";
float latitude = 75.4634;
float longitude = 69.43425;
int zoom = 13;
NSString *stringURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@@%1.6f,%1.6f&  z=%d", title, latitude, longitude, zoom];
NSURL *url = [NSURL URLWithString:stringURL];   
[[UIApplication sharedApplication] openURL:url];

NSString *title = @"title";
float latitude = 35.4634;
float longitude = 9.43425;
int zoom = 13;
NSString *stringURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@@%1.6f,%1.6f&z=%d", title, latitude, longitude, zoom];
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
