Follow your uitextview to define a UILabel.

UILabel *inputPlaceHolder;

PlaceHolder is not displayed when there is content. Display when no content is present. It is therefore possible to implement uitextviewdelegate in the corresponding class for the instance in which the following methods are used.

- (void)textViewDidChange:(UITextView *)textView{    if (textView.text.length == 0)    {        inputPlaceHolder.text = @"输入内容";    }    else    {        inputPlaceHolder.text = @"";    }}

Note the delegate that sets the label is the instance in which it is located.

inputPlaceHolder.delegate = selfinputPlaceHolder.text = @"输入内容"
