Show UITextField keyboard on firstResponder even w

问题:

I have a UITextField that is first responder. I want to show keyboard when entering the view but I want to do that the user will not be able to edit it and the cursor will be hidden all time as well.

When you click on a keyboard letter, it will be written in the UITextField, but the user will not be able to edit nothing there, even not to copy.

Thanks!

Ok, per my comment, my solution is to have a surrogate UITextField that has its hidden property set to YES. What I do is add that hidden text field to the view, and call becomeFirstResponder on it. The user has no idea this text field exists. In the delegate callback from the text field, I take the text the user typed in and add it to a UITextView (though you could add the text to whatever you wanted, like a UITextField like in your question). I turn off userInteractionEnabled for the visible text view. This creates the effect you desire.

I created a sample project that I uploaded to Github. (If you aren't familiar with it, just click the zip button to download it, unzip it, and open the .xcodeproj file). https://github.com/MaxGabriel/HiddenTextField

I had a UISearchBar property in my viewController. And I did it like this:

- (void)viewWillAppear:(BOOL)animated
{
    [self.searchBar becomeFirstResponder];
}

This should work the same for a UITextField.

As for disabling editing, use:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
    return NO;
}

You should have set your viewController to be the delegate of UITextField.

Edited answer: Try this:

1. [txtField becomeFirstResponder]; 
2. txtField.enabled = NO; 
3. when some press on keyboard, then txtField.enabled = YES;
