如何禁用 UITextField 中的双击键盘弹出窗口？

Question

I have several UITextFields. I want to disable the "double tap" that brings the autocorrection/keyboard. I'm using a tap function to chose which UITextField to activate.

You can tell a UITextField not to begin the editing process using the textFieldShouldBeginEditing Delegate method of UITextView:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
  if (some conditon) {
    return NO;
  } else {
    return YES;
  }
}

Apple documentation reference on the method: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html

some condition would likely be a check to see whether the user is selecting the UITextField to activate it, or whether it is already active and it should bring the keyboard up.

You could subclass UITextView to give it a "selected" property, and make it a UITextViewDelegate. If "selected" is false, then set it to true in textFieldShouldBeginEditing: and return NO; otherwise, return YES. That's just one random idea off the top of my head.
