Question

I have an array with strings. What is the best way to check if the first char of every string in the array is from the latin alphabet?

Answer 1

Basically you can use a character set like so:

NSString* string = @"This is a string";
NSCharacterSet *letters = [NSCharacterSet letterCharacterSet];
if([letters characterIsMember:[string characterAtIndex:0]]) {
    // This is a letter
}

The example speaks for itself 🙂
