问题描述
我尝试用 renderInContex
捕获 UIView
的图片,但它并不完全捕获子视图。 (例如,它不捕获 UITextView
中的单词,它不捕获 UIButton
所有。)
I am trying to capture an image of a UIView
with renderInContex
, but it does not fully capture all of the subviews. (For example, it doesn't capture the words in a UITextView
, and it doesn't capture a UIButton
at all.)
我可以使用什么?
编辑:
问题实际上是 t renderInContext
,而是我的实现。请参阅我的新问题:
The problem actually isn't renderInContext
, but instead is my implementation. See my new question: Detecting change in UIView and its subviews
推荐答案
这听起来像 renderInContext
可能工作,如果你先调整图形上下文。请尝试此操作(如果您尚未这样做):
It sounds like renderInContext
might work if you adjust the graphics context first. Try this if you haven't already done so: http://stackoverflow.com/a/3869804
