Question

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

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开始更新位置，您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;
    }
}

可能您可以尝试以下检查，看看是否有帮助：

不要每次都致电requestWhenInUseAuthorization。

检查locationServicesEnabled和authorizationStatus，仅当requestWhenInUseAuthorization为authorizationStatus且kCLAuthorizationStatusDenied返回locationServicesEnabled时才需要false

像，

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

        [self.locationManager requestWhenInUseAuthorization];

    }
}

希望它会有所帮助：）
