Question

我没有获得GPS位置更新。我正在使用iPad2来运行代码。这是我的代码：

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

        //location
        locationManager = [[[CLLocationManager alloc] init] autorelease]; // Create new instance of locMgr
        locationManager.delegate = self;

        locationManager.distanceFilter = kCLDistanceFilterNone; 
        locationManager.desiredAccuracy = kCLLocationAccuracyBest;

        [locationManager startUpdatingLocation];
        NSLog(@"locationManager startUpdatingLocation"); //this core runs correctly

...
}

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


- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation 
{
    location = [newLocation description];
    NSLog(@"new location: %@", location); //never printed   
}

我应该在首选项中允许定位吗？我期待iPad要求分享位置的权限，但我没有得到任何。

感谢

Answer 1

locationManager是保留财产吗？如果没有，请将其设置为1并在alloc + init行前添加self.，以便在该方法结束时不释放locationManager：

self.locationManager = [[[CLLocationManager alloc] init] autorelease];

还在[locationManager release];中添加dealloc。

Answer 2

我实际上删除了自动释放并在dealloc中添加了释放，就是这样。

我没有获得GPS位置更新。我错过了什么？
