iOS中的locationServicesEnabled＆gt; 4.0始终显示UIAlert

Question

我尝试使locationServicesEnabled函数正常工作......但无论locationServices是否启用，我的UIAlert都会显示出来！如何让它正常工作？

 @synthesize locationServicesEnabled
    -(void)viewDidLoad {
     [super viewDidLoad];

     if(![CLLocationManager locationServicesEnabled]) {
      self.locationManager = [[[CLLocationManager alloc] init] autorelease];
      locationManager.delegate = self;
      locationManager.desiredAccuracy = kCLLocationAccuracyBest;
      [locationManager startUpdatingLocation];
        } else {
            [[[[UIAlertView alloc] initWithTitle:@"Location services." 
                                         message:@"Location services are disabled." 
                                        delegate:nil 
                               cancelButtonTitle:@"OK" 
                               otherButtonTitles:nil] autorelease] show];       
        }
    }

提前谢谢！

看起来你的状况是倒退的。它目前说“如果没有启用位置服务，则开始更新其他警报”。

将if更改为：

if([CLLocationManager locationServicesEnabled])

删除!。
