Question

我进入了UIScrollView两个对象，一个Button和一个textField。当我按下textField时，我需要按钮向上移动，而textField向下移动。我怎么能这样做？

Answer 1

将您的UIButton保持在您的UITextField下方，或者您可以为Y位置提供一些特定值。

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
 {
      [UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDuration:1.0];
      //you can change the setAnimationDuration value, it is in seconds.
      CGFloat textFieldY = textField.frame.origin.y;
      CGFloat buttonY = button.frame.origin.y;
      CGRect textRect = CGRectMake(textField.frame.origin.x, buttonY, textField.frame.size.height, textField.frame.size.width);
      CGRect buttonRect = CGRectMake(button.frame.origin.x, textFieldY, button.frame.size.height, button.frame.size.width);
      [textField setFrame:textRect];
      [button setFrame:buttonRect];
      [UIView commitAnimations];
      return YES;
 }

和

相同

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {

      [UIView beginAnimations:nil context:NULL];
      [UIView setAnimationDuration:1.0];
      //you can change the setAnimationDuration value, it is in seconds.
      CGFloat textFieldY = textField.frame.origin.y;
      CGFloat buttonY = button.frame.origin.y;
      CGRect textRect = CGRectMake(textField.frame.origin.x, buttonY, textField.frame.size.height, textField.frame.size.width);
      CGRect buttonRect = CGRectMake(button.frame.origin.x, textFieldY, button.frame.size.height, button.frame.size.width);
      [textField setFrame:textRect];
      [button setFrame:buttonRect];
      [UIView commitAnimations];
      return YES;
 }

您可以使用按钮插座代替“按钮”。

注意 - 我没有测试过这段代码。希望它能奏效。

我可以使用UIScrollView吗？Xcode在两个不同的移动中移动两个不同的对象
