Question

How to write right in this situation:

I have some method, that return NSMutableArray*. Because method not started with init, new or alloc, how write in apple memory-management guide, i return autorealese object.

-(NSMutableArray*)someMethod {

    NSMutableArray *array = [NSMutableArray alloc] init] autorealese];
    //Some code here
    return array;
}

And i have some another methods, that call this one:

-(NSMutableArray*)method1 {
     NSMutableArray *array = nil;
     if(condition){
         array = [self someMethod];
     }
     return array;
}

-(NSMutableArray*)method2 {
     NSMutableArray *array = nil;
     array = [self method1];
}

Code work.But XCode analyze tool says that in method2 i get object with count 0. So, how to write this code good?

Answer 1

There is nothing wrong with your code, except that the method2 will return the array that is autoreleased. Thus whatever is calling this method should retain the return value.
