UITextView无意中添加新行？

问题描述

我有一个包含UITextField和UITextView的滚动视图。 UITextField返回键是Next，当按下它时，我调用[myTextView becomeFirstResponder];一个随机的新行插入到我的textview中，所以我从第二行开始。我如何避免这种情况？

I have a scroll view which contains a UITextField and a UITextView. The UITextField return key is "Next" and when this is pressed I call [myTextView becomeFirstResponder]; A random new line is inserted into my textview so I start on the second line. How do I avoid this?

同样重要的是要注意，直接点击UITextView而不是点击下一个键时不会发生这种情况。

Also important to note that this does not happen when I tap directly on the UITextView rather than tapping the next key.

提前致谢！

推荐答案

解决此问题的一个解决方案是实施 textFieldShouldReturn：委托方法，请务必返回否，而不是 YES 。通过返回否，换行符不会传递到文本字段。

One solution to solve this is when you implement the textFieldShouldReturn: delegate method, be sure to return NO, and not YES. By returning NO, the newline isn't passed on to the text field.

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    // move to next field or whatever you need
    [myTextView becomeFirstResponder];

    return NO;
}
