if(IS_OS_8_OR_LATER) {

[self.locationManager startUpdatingLocation]; 

并在info.plist中

NSLocationWhenInUseUsageDescription  :   App would like to use your location.
NSLocationAlwaysUsageDescription  :  App would like to use your location.

显示用户位置的代码:

//Get Location
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.distanceFilter = kCLDistanceFilterNone;
