alloc initWithObjects vs arrayWithObject

Question

I don't understand why if I write these code

icons = [[NSArray alloc] initWithObjects:
             @"appointment",
             @"work",
             @"anniversary",
             @"me",
             nil];

the app crashed. But then I replaced by these code

icons = [NSArray alloc] arrayWithObjects:
             @"appointment",
             @"work",
             @"anniversary",
             @"me",
             nil];

and the app did't crash. But there is the same affect between these methods ! I don't know why ? Can u help me ?

These methods differ by memory management. Second code gives you an autoreleased object, and if it works, you probably missed a retain call somewhere. We'd need more code to be sure, of course. — coverback

"you probably missed a retain call somewhere". I think you want to say release" instead of retain ? Yeah thank you — Proton

initWithObjects method means you have to release the object of array whenever this is not required as this is instance method and for more details click:
arrayWithObjects method means you don't need to release the object of array whenever this is not required as this is class method and for more details click:

If you are not clear with the points so revert me..
