IOS-didFailWithError：错误域= kCLErrorDomain代码= 0。 （kCLErrorDomain错误0。）“

Question

我试图获得经度＆amp;用户当前位置的纬度，我的代码就是这样：

- (void)viewDidLoad {
    self.locationManager=[[CLLocationManager alloc]init];
    [locationManager setDelegate:self];
    [locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
    [locationManager startUpdatingLocation];
}

-(void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
    float latitude=newLocation.coordinate.latitude;
    float longitude=newLocation.coordinate.longitude;
    NSLog(@"%f",latitude);
    NSLog(@"%f",longitude);
    [locationManager stopUpdatingLocation];

}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error 
{
    NSLog(@"didFailWithError: %@", error);
}

我总是从didFailWithError方法得到这个错误：

didFailWithError: Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)" 

Answer 1

我认为， 您需要在项目的.plist中添加以下权限

NSLocationWhenInUseUsageDescription，该值为Application would like to use your location

，其次是，在代码中添加[locationManager requestWhenInUseAuthorization];行。

  

我添加了这段代码：

- (void)viewDidLoad {
    self.locationManager=[[CLLocationManager alloc]init];
    [locationManager setDelegate:self];
    [locationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
    [locationManager requestWhenInUseAuthorization];
    [locationManager startUpdatingLocation];

}
