// 1. 懒加载初始化:
- (CLLocationManager *)locationManager{
if (!_locationManager){
self .locationManager = [[CLLocationManager alloc] init];
self .locationManager.delegate = self ;
}
return _locationManager;
}
- ( void )viewDidLoad {
[ super viewDidLoad];
// 2. 调用请求:
if ([[[UIDevice currentDevice] systemVersion] doubleValue] > 8.0)
{
//设置定位权限 仅ios8有意义
[ self .locationManager requestWhenInUseAuthorization]; // 前台定位
// [locationManager requestAlwaysAuthorization];// 前后台同时定位
}
[ self .locationManager startUpdatingLocation];
}
// 3.代理方法
- ( void )locationManager:(CLLocationManager *)manager didUpdateLocations:( NSArray *)locations{
NSLog (@ "%ld" ,locations.count);
}
@end
