iOS5.1中的定位服务不能正常工作
iOS5.1中的定位服务不能正常工作
提问于 2013-06-30 13:10:59
我有一个用Objective-C编写的简单应用程序，它使用CLLocationManager等获取我的当前位置。代码在iPhone 6.1模拟器上运行良好，但它不能在我实际的iPod触摸上运行。第三代iPod Touch正在运行iOS5.1，它确实要求用户启用位置服务，但它没有得到更新。如果你问我，我可以发布代码，但我认为只会有一个明显的兼容性问题，这将是一个相当简单的修复。任何帮助都将不胜感激！谢谢！~Carpetfizz

只需使用此委托
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
CLLocation *location = newLocation;
NSLog(@"%f,%f",location.coordinate.latitude,location.coordinate.longitude);
