限制HPGrowingTextView的字符数

Question

我正在使用HPGrowingTextView。我如何限制输入的字符数。例如，如果我设置100，那么用户不应该在上面输入100.谢谢提前

Answer 1

在HPGrowingTextView.m

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range
 replacementText:(NSString *)atext

{

//place on top below line of code

  NSInteger newTextLength = [textView.text length] - range.length + [atext length];

    if (newTextLength > 160)
    {
        // don't allow changed and limits the characters for eg...160

        return NO;
    }

//keep remaining code unchanged...


}

希望这有助于你..
