Answer 1

You can check the size of your text with the font like this:

[@"MYString" sizeWithFont:myFont];

Knowing this, you can compare it with the size of the textview and now when your text is bigger!

Answer 2

到达键盘时向上移动文本视图，或者在文本超出最大文本视图大小时降低字体大小。

Answer 3

Take this UITextView in UIScrollView and then set content size with the contentSize of UITextView and scroll the UIScrollView at bottom

set content size like bellow..

float sizescrollview = yourTextView.frame.origin.y + yourTextView.frame.size.height + 20;
scrview.contentSize=CGSizeMake(320, sizescrollview);

and scroll the UIScrollView above of the keyboard like bellow..

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
scrView.frame = CGRectMake(0, -150, 320, scrView.frame.size.height);
[UIView commitAnimations];

i hope this help you...
