我想让IPAD从相册中选择一张照片

            pickerController = [ [ UIImagePickerController alloc ] init ] ;
            pickerController.delegate   = self ;
            pickerController.editing    = NO ;
            pickerController.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;

            [ self presentViewController : pickerController animated : YES completion : nil ] ;

当我在iPad上使用它时,该应用程序不断崩溃,但在iPhone上运行良好.

我的主要问题是在Core Data之外保存和检索数据.

我期待用持久数据保存1个变量.

按下第二个按钮后例行程序崩溃.

override func viewDidLoad() {

 super.viewDidLoad()

 var amy="2"
 NSUserDefaults.standardUserDefaults().setObject((amy), forKey: "ggpass")
}


@IBAction func pass(sender: AnyObject) {

// Retrieve the original Variable

NSUserDefaults.standardUserDefaults().synchronize()

     var aname5 = (NSUserDefaults.standardUserDefaults().objectForKey("ggpass"))!  as String
      gpass = (aname5.toInt())!

      gpass=gpass+1

      ///Save Data

      NSUserDefaults.standardUserDefaults().setObject((gpass), forKey: "ggpass")


    }
