I have a UIScrollView which has a subview UITextView. When I added text to UITextView by code, the view is scrolling to the last line. I want the view not to scroll when I add text to UITextView by code. Anyone can help me fix the problem?

我们只是在更改 UITextView 中的文本之前将 UITextView 中的 setScrollEnabled 设置为 YES，并在更改文本后设置为 NO.
We just set YES the setScrollEnabled in UITextView before we change the text in UITextView and set NO after we change the text.
这里是示例代码
[yourTextView setScrollEnabled:YES];
yourTextView.text = [someString copy];
[yourTextView setScrollEnabled:NO];:)
