I've tried this
NSCharacterSet *myCharSet = [NSCharacterSet characterSetWithCharactersInString: myString];
[myCharSet count];
But get a warning that NSCharacterSet may not respond to count. This is for desktop apps and not iPhone, which I think the above code works with.
NSString *string = @"0̄ ";
__block NSUInteger count = 0;
[string enumerateSubstringsInRange:NSMakeRange(0, [string length])
options:NSStringEnumerationByComposedCharacterSequences
usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) {
count++;
}];
NSLog(@"%ld %ld", (long)count, (long)[string length]);
