(iphone)将子视图的框架设置在超级视图的边界之外? [英] (iphone) set subview's frame outside of superview's bound?

问题描述

我注意到我可以将子视图放置在Superview的范围之外(部分或全部).
我想知道这是否可以接受，因为在通常的iphone视图编程中这似乎是异常的.

I noticed that I can place subview outside of superview's bound (either partly or fully).
I wonder if that's acceptable, since it seems to be abnormal in usual iphone view programming.

谢谢.

推荐答案

这是可以接受的，有时甚至是惯例-滚动视图或其他复合"视图的自定义实现，例如，通常将对象放置或移动到超视图范围之外

This is acceptable and sometimes even common practice - custom implementations of scroll views or other "composite" views, for example, commonly place or move objects outside the superview's bounds.

您可能对 UIView 属性感兴趣 <代码> clipsToBounds ，它将子视图绘图限制为仅超级视图的边界.

You may be interested in the UIView property clipsToBounds, which restricts subview drawing to only the bounds of the superview.
