将视图作为子视图添加到多个视图时遇到麻烦-iPhone开发者 [英] having trouble adding a view as a subview to multiple view - iphone dev

问题描述

我需要将一个视图添加到应用程序中的多个视图.我正在运行一个遍历所有UIView并将该视图添加为子视图的函数.

I need to add a view to multiple views in app. I am running a function which loops through all the UIViews and add that view as subview.

我已经做了类似的事情:

I have done something like this:

-(void) setViewForEachSegment: (UIView*)view {
    int i;
    for (i = 0; i < [segments count]; i++) {
        [[segments objectAtIndex:i] addSubview: view]
    }
}

此处的细分是 UIViews 的数组.

现在，正在发生的事情是子视图仅添加到了最后一个段.

Now, what is happening is that the subview is added only to the last segment.

还有其他人遇到同样的问题吗?我已经研究了好几个小时，但不知道如何解决.

Has anyone else faced the same problem? I have been working on it for many hours, but don't know how to fix it.

推荐答案

您不能将一个视图添加到多个视图中，因为一个视图一次只能有一个父视图.这由 UIView 的 superView 属性表示.

you can't add one view into multiple views, because a view could have single parent view at a time. which is represented by superView property of your UIView.

每次，在添加到View之前，先创建 UIView 的新对象

Each time Create a new object of your UIView before adding to View,
