Detect if a user has typed an emoji character in UITextView

Question

I have a UITextView and I need to detect if a user enters an emoji character.

I would think that just checking the unicode value of the newest character would suffic

Another solution: https://github.com/woxtu/NSString-RemoveEmoji

Then, after import this extension, you can use it like this:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
    // Detect if an Emoji is in the string "text"
    if(text.isIncludingEmoji) {
        // Show an UIAlertView, or whatever you want here
        return NO;
    }

    return YES;
}

Hope that helps ;)
