Objective-C NSString for loop with characterAtIndex

Question

I\'m trying to loop through a NSString, character by character, but I\'m getting a EXC_BAD_ACCESS error. Do you have an idea how to do this right? I\'ve been googling for hours

If you want to find the location of a character in a string you can use this:

NSUInteger position = [text rangeOfString:@"."].location;

if the character or text is not found you will get a NSNotFound:

if(position==NSNotFound)
    NSLog(@"text not found!");
