Xamarin.IOS切换按钮？

Question

是否有 xamarin.ios 的切换按钮？如果没有，更好的方法是使用两个按钮并切换它们的隐藏属性?

谢谢

解决您的问题：

public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();
        // Perform any additional setup after loading the view, typically from a nib.

        UIButton btnPlayAndStop = new UIButton (new CGRect (100, 100, 50, 50));
        btnPlayAndStop.BackgroundColor = UIColor.Gray;
        btnPlayAndStop.Tag = 0;
        btnPlayAndStop.SetImage (UIImage.FromFile ("play.png"), UIControlState.Normal);
        btnPlayAndStop.TouchUpInside += delegate {
            if (0 == btnPlayAndStop.Tag) { 
                btnPlayAndStop.Tag = 1;
                btnPlayAndStop.SetImage (UIImage.FromFile ("stop.png"), UIControlState.Normal);
            }
            else if (1 == btnPlayAndStop.Tag) {
                btnPlayAndStop.Tag = 0;
                btnPlayAndStop.SetImage (UIImage.FromFile ("play.png"), UIControlState.Normal);
            }
        };
        this.View.AddSubview (btnPlayAndStop);
    }
