Apple's Cocoa Memory Management Programming guide shows this pattern for init:

- (id)init {
    if ((self = [super init])) {// superclass may return nil
        // your initialization code goes here
    }
    return self;
}

Newb question: In the case of
id myObject = [[MyObject alloc]init];
what happens to the allocated memory if the [super init] fails and how do I handle it since I dont have a self to release?

If [super init] fails it should have done [self release] before returning nil.
