When I test my app on IOS7 simulator.
Sometimes I found it is weird when I using sizeToFit of a UITextView.
The frame after sizeToFit seems right but the text can only show partly just like the photo below. (The gray area represents the UITextView new frame after sizeToFit, the whole sentence should be "which sparked a tense relationship between the two.")

The UITextView text is set via attributedText.
It seems the problem occurs with some sentences only and is OK for most sentences.
I met this problem several times and can not solve it yet. Any help will be appreciated. Thanks.
Update:
Finally I solve the problem in an ugly way. I reset the text of the textView.
NSString *text = textView.text;
textView.text = @"";
textView.text = text;
Now it can show the whole content after sizeToFit. I think it seems like a IOS 7's bug.
