获取 UIView 的可见矩形 [英] Getting Visible Rect of UIView
本文介绍了获取 UIView 的可见矩形的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
假设 UIView 仅沿着边缘(没有其他视图在中间的某个地方将其分解)?
What's the simplest method to get the visible rect of any arbitrary UIView as a CGRect, assuming that the UIView is only clipped along the edges (no other views breaking it up somewhere in the middle)?
为了清楚起见，此方法不应仅检索相对于视图的超视图的可见矩形.但至少相对于它的所有祖先，理想情况下也相对于所有兄弟姐妹.
For clarity, this method should not only retrieve the visible rect relative to the view's superview. But relative to all it's ancestors at a minimum and ideally relative to all siblings as well.
推荐答案
试试这个！
CGRect visibleRect = CGRectIntersection(self.frame, superview.bounds);
