ios - 添加一个 uiview 来控制某些 uibuttons 无法正常工作 iphone monotouch

Question

我使用此代码在 UIView 中添加 3 个 UIButtons，然后将它们添加到我的屏幕。

UIView  buttonsContainerView = new UIView (new Rectangle (0,0,(int) this.View .Frame .Width ,40));
            UIButton  b;
            for(int i=0;i<3;i++){
                b= new RltTabBarButton ();
                b.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
                if(i==0){
                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Details";
                    b.Frame = new RectangleF (0,350,108,40);
                    b.Enabled =true ;
                }else if(i==1){
                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Map";
                    b.Frame = new RectangleF (110,350,100,40);
                    b.Enabled =true ;
                }else if(i==2){


                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Agent";
                    b.Frame = new RectangleF (212,350,108,40);
                    b.Enabled =true ;
                }
                buttonsContainerView .AddSubview (b);

            }
this.View .AddSubview (buttonsContainerView );

当我运行我的应用程序时。按钮添加到正确的位置。但它们的 TitleLable 上不包含任何 Text。当我设置这个项目时。而且它们看起来像一些图像，因此我无法单击它们并与它们交互。

我将其Enabled字段设置为true，但没有进行任何更改。

编辑:根据答案我将代码更改为:

UIView  buttonsContainerView = new UIView (new Rectangle (0,0,(int) this.View .Frame .Width ,40));

            UIButton  DetailsButton= new UIButton (UIButtonType.RoundedRect  );
            DetailsButton.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
            DetailsButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                  UIControlState.Normal );
            DetailsButton.SetTitle ("Details",UIControlState.Normal );
            DetailsButton.Frame = new RectangleF (0,350,108,40);
            buttonsContainerView .AddSubview (DetailsButton);

            UIButton  MapButton= new UIButton (UIButtonType.RoundedRect );
            MapButton.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
            MapButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
            MapButton.SetTitle ("Map",UIControlState.Normal );
            MapButton.Frame = new RectangleF (110,350,100,40);
            buttonsContainerView .AddSubview (MapButton);

            UIButton  AgentButton= new UIButton (UIButtonType.RoundedRect  );
            AgentButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
            AgentButton.SetTitle ("Agent",UIControlState.Normal );
            AgentButton.Frame = new RectangleF (212,350,108,40);
            buttonsContainerView .AddSubview (AgentButton);

            this.View .AddSubview (buttonsContainerView );

但没有任何变化。我们无法点击按钮。它们看起来像图像。我相信它与 buttonsContainerView 有关，也许与它的 EnableInputClicksWhenVisible 有关。当我调试该 View 的应用程序时，调试器在想要执行其值时会出现一些异常。我只能复制这个的头部:

MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: -[UIView enableInputClicksWh…

我不知道如何修复它。

Answer 1

我明白了。问题是我设置了 buttonsContainerView( 包含按钮的 View )40.但是设置按钮350的高度位置。当按钮的框架位于其父 View 的框架之外时，它不会响应您的触摸。
