I'm trying to limit text user input to latin/english characters and emojis.
Is it possible to create an NSCharacterSet that includes all of these characters?
I tried using a keyboard type ASCIICapable on my input views, but then I don't get emoji input.
Thanks in advance.
There's nothing built in to create such a specific character set. You'll have to do it yourself by character range.
The Emoji characters are essentially in the range \U1F300 - \U1F6FF. I suppose a few others are scattered about.
NSMutableCharacterSet to build up what you need.
NSMutableCharacterSet *aCharacterSet = [[NSMutableCharacterSet alloc] init]; [aCharacterSet addCharactersInRange:NSMakeRange(0x1F300, 0x1F700 - 0x1F300)]; // Add most of the Emoji characters [aCharacterSet addCharactersInRange:NSMakeRange('A', 'Z'-'A'+1)]; // Add uppercase [aCharacterSet addCharactersInRange:NSMakeRange('a', 'z'-'a'+1)]; // Add lowercase
