CTFrameGetVisibleStringRange错误地计算字符串末尾的空格? [英] CTFrameGetVisibleStringRange Incorrectly Counting Spaces at End of String?
问题描述
我正在使用 CoreText
,我注意到 CTFrameGetVisibleStringRange
错误地对字符串末尾的空格进行计数,在框架中不可见。仅供参考,我在 NSMutableAttributedString
的末尾使用 insertAttributedString
作为字符串@添加空格。有人知道如何解决这个问题吗?
I'm working with CoreText
and I notice that CTFrameGetVisibleStringRange
incorrectly counts spaces at the end of the string which are NOT visible in the frame as being visible. FYI, I am adding the space as a string @" " using insertAttributedString
to the end of my NSMutableAttributedString
. Does anyone know how to fix this?
更新:仍然没有找到解决方案,这是预期的行为吗?还是这只是一个错误?
UPDATE: Still haven't found a solution to this, is this the intended behavior? Or this just a bug?
推荐答案
这是一个错误。要解决此问题,请用其他方法替换字符串末尾的,执行所需的操作,然后在末尾重新插入。
This is a bug. To work around this replace the " " at the end of the string with something else, do whatever you need to do, then reinsert the " " at the end.
