位置权限对话框在iOS 10中提示了大量时间

Question

在iOS 10中，有时在安装应用程序时，位置权限提示会打开大量时间并挂起所有应用程序而无法进一步移动。

这是我的代码在iOS 10之前有效

-(void)startLocationManager{  
    self.locationManager=[[CLLocationManager alloc]init];
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    self.locationManager.delegate=self;
    if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
        [self.locationManager requestWhenInUseAuthorization];
    }

    [self.locationManager startUpdatingLocation];
}

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
    if (self.myCurrentLocation==nil) {
        self.myCurrentLocation=[locations lastObject];
        [[WALocationManager WALocationSharedInstance] checkLatestLocation];
    }
    else{
        if (self.myCurrentLocation.horizontalAccuracy < 0){
            return;
        }
        self.myCurrentLocation=[locations lastObject];
        if([[WALocationManager WALocationSharedInstance] currentLocation]!=self.myCurrentLocation ){

        }
    }
}

在我的plist文件中，

<key>NSLocationAlwaysUsageDescription</key>
<string>This app will use your location to get most nearyby activity around you.</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>This app will use your location.</string>

无论iOS 10如何，只有在授予权限的情况下才应启动位置更新，还应在请求权限之前检查是否已授予权限：

-(void)startLocationManager{
    self.locationManager=[[CLLocationManager alloc]init];
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    self.locationManager.delegate=self;
    // Check for current permissions
    [self checkLocationAuth:[CLLocationManager authorizationStatus]];
}

-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
    [self checkLocationAuth:status];
}


-(void)checkLocationAuth:(CLAuthorizationStatus)status{
    switch (status) {
        case kCLAuthorizationStatusAuthorizedWhenInUse:
        case kCLAuthorizationStatusAuthorizedAlways:
            [self.locationManager startUpdatingLocation];
            break;
            // did not ask for permission, ask now
        case kCLAuthorizationStatusNotDetermined:
            if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
                [self.locationManager requestWhenInUseAuthorization];
            } else { // iOS < 8? implicitly request permission
                [self.locationManager startUpdatingLocation];
            }
            break;
        // Also need to handle failures, etc
        default:
            break;
    }
}

也许你可以尝试下面的检查，看看它是否有帮助：

每次都不要调用requestWhenInUseAuthorization 。

检查locationServicesEnabled和authorizationStatus ，仅当authorizationStatus为kCLAuthorizationStatusDenied并且locationServicesEnabled返回false时才调用requestWhenInUseAuthorization 。

喜欢，

if(![CLLocationManager locationServicesEnabled] && 
   [CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied)
{
   if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {

        [self.locationManager requestWhenInUseAuthorization];

    }
}

希望它会有所帮助:)
