1. 向 target中info 加入  NSLocationWhenInUseUsageDescription，string 类型。值是描写叙述为什么须要用户位置，这句话会出如今 提示用户是否同意app訪问用户位置提示框中。

2. 在appdelegate.m 的 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
中加入

    //地图定位

    CLLocationManager* locationManager = [[CLLocationManageralloc]init];

    if ([[UIDevicecurrentDevice].systemVersionfloatValue] >= 8.0) {

        [locationManager requestWhenInUseAuthorization];

    }

    self.mapView = [[QMapView alloc] initWithFrame:self.view.frame];

   self.mapView.delegate =self;

   self.mapView.showsUserLocation =YES;

    //缩放级别

    _mapView.zoomLevel =13;

    [self.view addSubview:_mapView];
