Question

I have a method as follows. I want to know if the returned dictionary is autoreleased or not.

- (NSDictionary *)someMethod {
    NSMutableDictionary *myDict = [[NSMutableDictionary alloc] init];           //did not autorelease it here

    //-------------------------------
    //Some code
    //-------------------------------
    return (NSDictionary *) myDict;
}

Note: I haven’t added autorelease while initializing the object on purpose.

Answer 1

myDict would not be autoreleased. Would be retained. Replace the return line for

return [myDict autorelease]; // no cast needed

Otherwise you are most likely introducing a leak.
