解决方法：
1.在info.plist中添加key；
NSLocationWhenInUseDescription，允许在前台获取GPS的描述
NSLocationAlwaysUsageDescription，允许在后台获取GPS的描述
%20%20%20
%20%20%20
2.在代码定位中，做版本区分和授权请求：
if ([CLLocationManager locationServicesEnabled]) { if (!self.locationManager) { self.locationManager = [[CLLocationManager alloc] init]; } self.locationManager.delegate = self; self.locationManager.distanceFilter=1.0; self.locationManager.desiredAccuracy = kCLLocationAccuracyBest; if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) { [self.locationManager requestAlwaysAuthorization]; // 永久授权 [self.locationManager requestWhenInUseAuthorization]; //使用中授权 } [self.locationManager startUpdatingLocation];//开启位置更新 self.delegate = delegate; }
