Where are the memory leaks in my for ... in loop with addObject

Question

There seem to be some memory leaks in the following loop:

NSMutableArray *array1 = [[NSMutableArray alloc] init];
for(SomeClass *someObject in array2){    //has already been populated;
    if (someObject.field == desiredValue){
        [array1 addObject:someObject];
    }
}
//EDIT:
//use array1 for very secret operations
[array1 release];

Any ideas why?

Answer 1

Are you releasing all your retained properties in SomeClass of yours? Make sure in dealloc release all retained properties.. Make sure your SomeClass is leak free..
