I have a UITextView but i do not want the keyboard to provide the user with the 'return' key. So in my xib file i set the keyboard type to UIKeyboardTypeTwitter which basically replaces the 'return' key with the '@' and '#'.
However when tapping the '123' button on the keyboard and thus moving into UIKeyboardTypeNumbersAndPunctuation mode, the 'return' key shows up in the bottom right hand side. Is there a way to detect when the user taps on the '123' and then at that time, keep the '@' and '#' symbols in this situation?
You don’t have enough control over the keyboard for that (and might not even have as much as you think with the UIKeyboardTypeTwitter approach, if the user has a third-party keyboard that works with that); your best option is to detect when they’ve hit Return (via the UITextViewDelegate method -textView:shouldChangeTextInRange:replacementText:) and blocking the newline insertion that way.
