1：判断didUpdateLocations这个方法调用几次 _currLocationl = [locations lastObject]; NSString *loc=[NSString stringWithFormat:@"%f,%f",_currLocationl.coordinate.latitude,_currLocationl.coordinate.longitude]; NSTimeInterval locationAge = -[_currLocationl.timestamp timeIntervalSinceNow]; if (locationAge > 1.0){//如果调用已经一次，不再执行 return; }else{ UZGPersonalSetting *s=[UZGPersonalSetting getInstance]; if (nil == s.session) {//已登录 [_locateShop initHttpLocateShopWithType:@"GPS" andAddress:loc alert:@"" GPSData:loc]; }else{ if ([[NSUserDefaults standardUserDefaults] boolForKey:@"firstLaunch"]){ _locationViewMa = [UZGStartLocationViewManager sharedAlertViewManager]; _locationViewMa.delegate=self; [_locationViewMa show]; } [_locateShop initHttpLocateShopWithType:@"NAME" andAddress:_locateAddress alert:@"" GPSData:loc]; } } 2：判断是否定位成功了 if (_currLocationl.horizontalAccuracy > 0) {//已经定位成功了 [_locationManager stopUpdatingLocation]; }else{ }
