问题
When we enter character in textfield then it is enabling the return key. But in our requirement we need to enable the return key when length is more than 5. But now as soon as we enter character it is enabling the return key. Do we need to customize the keyboard or is there any other solution available. Thanks in advance.

Well I think you should handle it in the UITextField delegate :
- (BOOL) textFieldShouldReturn:(UITextField*) textField {
return textField.text.length > 0;
}
