推荐答案

您通常会将视图控制器指定为文本字段的委托然后实现 textFieldShouldReturn：方法，例如：

You would typically assign your view controller as the text field's delegate and then implement the textFieldShouldReturn: method, e.g.:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    otherTextField.text = @"World"
    return YES;
}
