정말 엉망입니다. 나는 그것과 레이블에 ScrollView가있는 View를 가지고 있습니다. 이 경우 스크롤이 제대로 작동합니다. clickFoo 액션을 생성하고, 수십 개의 UIViews처럼 Partial 코드를 넣었지만, 이제는 끔찍한 스택 추적 (아래 참조)이 발생합니다. 버튼과 액션을 제거하지만 UIScrollView의 Scrolling 이벤트에 대한 핸들러를 넣으면 같은 결과를 얻습니다. 왜 이런 일이 일어나고 있는지 모르겠다. 이것은 정말로, 정말 간단한 물건입니다.MonoTouch - ScrollView + 모든 이벤트 = 충돌
레코드의 경우 scrollview는 100x40이고 레이블과 버튼은 scrollview에 없습니다.
나는이 내있는 viewDidLoad에서 다음 코드
public partial class Testing : UIViewController
{
#region Constructors
// The IntPtr and initWithCoder constructors are required for items that need
// to be able to be created from a xib rather than from managed code
public Testing (IntPtr handle) : base(handle)
{
Initialize();
}
[Export("initWithCoder:")]
public Testing (NSCoder coder) : base(coder)
{
Initialize();
}
public Testing() : base("Testing", null)
{
Initialize();
}
void Initialize()
{
}
#endregion
List<UIImageView> _imageViews;
public override void ViewDidLoad()
{
base.ViewDidLoad();
_imageViews = new List<UIImageView>();
UIButton btnNumber;
/* btnNumber = new UIButton(new RectangleF(new PointF(32f*x,0f), new SizeF(31f,31f)));
btnNumber.SetImage(UIImage.FromBundle("images/7.png"), UIControlState.Normal);
btnNumber.SetImage(UIImage.FromBundle("images/7.png"), UIControlState.Highlighted);*/
UIImageView imgView;
scrollView.ContentSize = new System.Drawing.SizeF(400, 31);
for (int x=0;x < 30; x++) {
imgView = new UIImageView(new RectangleF(new PointF(32f*x,0f), new SizeF(31f,31f)));
imgView.Image = UIImage.FromBundle("images/7.png");
scrollView.AddSubview(imgView);
_imageViews.Add(imgView);
}
}
partial void clickFoo (UIButton sender)
{
lblInfo.Text = "Clicked";
}
} [ Code pasted in updated @12:07pm EDT ]
나는 다음과 같은 예외 스택 수 (내가 찾을 고전적인, 매우 실망 "이봐, 뭔가 이벤트 관련 어딘가 잘못이다")
