Ios CLLocation当前位置不工作

我的类中有此代码

ViewController

：

CLLocationManager *locationManager;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    locationManager = [[CLLocationManager alloc] init];
    [locationManager requestWhenInUseAuthorization];
}


- (IBAction)getCurrentLocation:(id)sender {
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];
}

#pragma mark - CLLocationManagerDelegate

-(void) locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    NSLog(@"Did finish with error - %@", error);
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Failed to get your location" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {

    NSLog(@"did Update Location - %@", newLocation);
    CLLocation *currentLocation = newLocation;

    if(currentLocation != nil) {
        _longitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
        _latitudeLabel.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
    }
}

但我没有得到允许访问的位置或弹出窗口

我正在使用核心位置框架

点击按钮，我正在打印标签中的纬度、经度和地址

我正在模拟器上测试此代码。

在viewDidLoad中尝试此代码

//---- For getting current gps location
    locationManager = [CLLocationManager new];
    locationManager.delegate = self;

    if ([locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])  {

        [locationManager requestWhenInUseAuthorization];
    }

    locationManager.distanceFilter = kCLDistanceFilterNone;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation];
    //------

您还必须为NSLocationAlwaysUsageDescription或nsLocationWhenUsageDescription键添加字符串到应用程序的Info.plist。

有时模拟器无法与支持位置的服务配合使用

苹果设备进行完美测试

在
info.plist
文件中添加以下键以获得允许访问弹出窗口


或者将它们添加为更新
info.plist
文件源代码

<key>NSLocationAlwaysUsageDescription</key>
<string>message for location uses</string>

<key>NSLocationWhenInUseUsageDescription</key>
<string>message for location uses</string>

NSLocationAlwaysUsageDescription
位置使用信息
NSLocationWhenUse用途说明

我提醒您在plist中添加授权请求，并使用您可以获得的设备进行检查。您是否在.plist中添加了授权请求说明？请检查上面的KAR check链接，它为您提供了我在info plist文件中添加的解决方案。感谢@user3182143我提醒您在plist中添加授权请求，并使用您可以获得的设备进行检查。您是否在.plist中添加了授权请求说明？请检查上面的KAR check链接，它为您提供了在info plist文件中添加的解决方案。谢谢@user3182143
