UITextView 无意中添加了新行?

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];一个随机的新行被插入到我的 textview 中，所以我从第二行开始.我该如何避免这种情况?

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，当我直接点击 UITextView 而不是点击下一个键时，这不会发生.

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

解决这个问题的一个方案是当你实现textFieldShouldReturn:委托方法时，一定要返回NO，而不是 YES.通过返回 NO，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;
}
