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);
