Answer 1

Also, you can use the delegate methods.

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

Answer 2

Firstly, the [...] aren't needed if you're not sending a message.

Number.editable = NO;
[Number resignFirstResponder];
Password.editable = NO;
[Password resignFirstResponder];

But this is not the cause of error. The .editable property is only defined for UITextView, not UITextField. You should set the .enabled property for a UITextField (note that a UITextField is a UIControl).

Number.enabled = NO;
...

Returning NO from shouldChangeCharactersInRange would be better choice because if text is longer than the textfield width, then above solution will give problem, because user won't be able to see all text(i.e. text hidden beyond the text field width)

Answer 4

textField.userInteractionEnabled = NO;

Hope this helps..
