On desktop Cocoa I can put in a custom formatter on a textfield and
get what I'm looking for. On iPhone, I can say I'm a bit confused as
to the best way to handle this.
Given a UITextField and my desire to have the user type in an IP
address, it sounds like it could be simple, but I can't figure it out.
Using
- (BOOL)textField:(UITextField *)textField
shouldChangeCharactersInRange:(NSRange)range replacementString:
(NSString *)string
works fine if I'm assuming the user is simply typing in the text going
forward. The problem is if a user edits the text field then they lose
their place as I set the text.
So my guess to this is that no I cannot do this (though I'm sure I've
seen it on the iPhone), but would there be a good way to handle this
properly?
