Find the location of a specific character in NSString

Question

How to find the location of a specific character in an NSString?

I tried this, but it returns an empty range (I want to find the location "?"):

NSRange range = [@"This is a ? test to see if it works" rangeOfCharacterFromSet:[NSCharacterSet characterSetWithCharactersInString:@"?"]];

Answer 1

You must do something else wrong. Because it is absolutely correct and returns {10, 1}. At least on my mac it does; -)

Answer 2

Maybe this will work?

NSString* s = @"hello?";
NSRange range = [s rangeOfString:@"?"];
