从另一个子视图的内部和下方添加子视图(Add a subview from within and below another subview)

从另一个子视图的内部和下方添加子视图(Add a subview from within and below another subview)

在iOS应用中，我在主视图中添加了一个子视图：

[self.view addSubview:firstUIImageSubview];

但是在子视图类firstUIImageSubview中，我正在创建并添加另一个我希望放在第一个子视图下面的子视图（secondUIImageSubview）：

[self insertSubview:secondUIImageSubview belowSubview:self];

我的问题是第二个子视图显示在第一个子视图上方，当我想在下面。 怎么可能实现这一目标？ 谢谢。

In an iOS app, I am adding a subview to my main view with:

[self.view addSubview:firstUIImageSubview];

However in the subview class firstUIImageSubview, I am creating and adding another subView (secondUIImageSubview) that I would like to put below the first subview with:

[self insertSubview:secondUIImageSubview belowSubview:self];

My problem is that the second subview is displayed above the first subview when I want to have it below. How is it possible to achieve that ? Thanks.

最满意答案

这应该可以解决问题。

[self.superview insertSubview:secondUIImageSubview atIndex:0];

This should do the trick.

[self.superview insertSubview:secondUIImageSubview atIndex:0];
