Here in [NSMutableArray array] you don't have to release array it will be released automatically. & if you will write [NSMutableArray alloc] init] you will have to release array so [[NSMutableArray array] will be equivalent to [[[NSArray alloc] init] autorelease];

I edit this , ImageList = [[NSMutableArray alloc] init]; as ImageList = [[[NSMutableArray alloc] init] autorelese] ; but it didn't work. What should be the error
The first remains in memory until you release it, the second lasts until the end of the run loop iteration.

NSMutableArray no need to release memory and [NSMutableArray alloc] init] u must be release it.

when ARC does work, you have to release objects come from methods including init,alloc,new,copy and mutableCopy, like [NSMutableArray alloc] init]. If not, the objects will be registered to autoreleasepool, like [NSMutableArray array].
