ios8地图开发的报错

报错如下：Trying to start MapKit location updates without prompting for location authorization. Must call -[CLLocationManager requestWhenInUseAuthorization] or -[CLLocationManager requestAlwaysAuthorization] first.

网上一搜大把类似的帖子

解决办法：在工程的info.plist文件里面添加两项属性。value值为yes

　　　　　　NSLocationWhenInUseUsageDescription

　　　　　　NSLocationAlwaysUsageDescription

　　　　

代码里面写：

　　　

 _locationManager=[[CLLocationManager alloc]init];

     if(![CLLocationManager locationServicesEnabled]||[CLLocationManager authorizationStatus]!=kCLAuthorizationStatusAuthorizedWhenInUse){

         [_locationManager requestWhenInUseAuthorization];

     }

     [_locationManager setDelegate:self];

     [_locationManager requestAlwaysAuthorization];        //NSLocationAlwaysUsageDescription

     [_locationManager requestWhenInUseAuthorization];     //NSLocationWhenInUseDescription
