Does removeObject release the object in an NSMutableArray of objects?

I was wondering when you remove an object using removeObject in an array if that removed object is handled properly. Would the object being removed be released?

    As everybody has said, the object of a NSMutableArray is released after it is removed from the array.

    If you don´t want to release the object, retain it just before you call remove object method. In this case, you are responsible for it to release it later:

    MyClass *objectToBeRemoved=[myArray objectAtIndex:indexPath.row];
    [objectToBeRemoved retain];
    [myArray removeObject:objectToBeRemoved];
