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

Answer 1

Well you can detect whether it only has ascii characters using this:

[myString canBeConvertedToEncoding:NSASCIIStringEncoding];

It will say no if it fails (or has emoji). Then you can do a if else statement that does not allow them to click enter or something.
