解决 UITextView 没有 ShouldReturn 事件

直接上代码吧
通过改变的字符,判断是否存在回车
swift版

    func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {        if text == "\n"        {            self.inputView.resignFirstResponder()            return false        }        return true    }

OC版

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{    if ([text isEqualToString:@"\n"]) {        [self.inputView resignFirstResponder];        return NO;    }    return YES;}
