How to iterate through the characters of an NSString

Question

NSString *myStrings = @"abcdefghijklmnopqrstuvwxyz";

How could I iterate each of the letters (a, b, c, d, e, etc..) in an Objective-C for loop?

Answer 1

One way is to use a simple for-loop:

for (NSInteger charIdx=0; charIdx<myStrings.length; charIdx++)
    // Do something with character at index charIdx, for example:
    NSLog(@"%C", [myStrings characterAtIndex:charIdx]);
