Objective-C Loop Through NSMutableArray?

Question

Hello!

Very simple question - how might I iterate through a NSMutableArray and do things for each item?

Much like the for loop in other langs:

foreach(array){ dosomething(); }

Thanks! Christian Stewart

Answer 1

for (ItemType *i in array) {
     [i doSomething];
}

Answer 2

If you want to call a method in each one, use

[array makeObjectsPerformSelector:@selector(eatFish)];

or if you want to pass an argument,

[array makeObjectsPerformSelector:@selector(eat:) withObject:myFishObject];
