1. 向 target中info 添加 NSLocationWhenInUseUsageDescription，string 类型，值是描述为什么需要用户位置，这句话会出现在 提示用户是否允许app访问用户位置提示框中。
2. 在appdelegate.m 的 - (BOOL)application:(UIApplication
*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
中添加
//地图定位
CLLocationManager* locationManager = [[CLLocationManager alloc] init];
if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
[locationManager requestWhenInUseAuthorization];
}
3. 添加腾讯地图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];
