This isn’t difficult, you really need to check the docs for NSString:

Example:

if ([myTextView.text length] == 2) {
    myTextView.text = [myTextView.text stringByAppendingString:@"++"];
} else if ([myTextView.text length] == 3) {
    myTextView.text = [myTextView.text stringByAppendingString:@"+"];
} if ([myTextView.text length] == 4) {
    myTextView.text = @"invalid";
}
