Objective C : Array iteration

Normal:

[sampleArray enumerateObjectsUsingBlock:^(NSString *symbol, NSUInteger idx, BOOL *stop) {
NSLog(@"%@", symbol);

if ([symbol isEqualToString:@"8″]) {
*stop = YES;
}
}];

Reverse:

[sampleArray enumerateObjectsWithOptions:NSEnumerationReverse usingBlock:^(NSString *symbol, NSUInteger idx, BOOL *stop) {
NSLog(@"%@", symbol);

if ([symbol isEqualToString:@"8″]) {
*stop = YES;
}
}];
