I am allocating an object like

A *a = [[A alloc] init];

At another point I am forcefully setting

a = nil;

Does it flash a message to ARC that the object can be released now?

    Quick answer – YES.
    Once you set your object to nil it will get killed by Arc (most of the cases, from my experience you can lay your trust on ARC)

    Dealloc methods in arc will be created for you. You must not make a dealloc call directly. However you can still create a custom dealloc method if you need to release resources other than instance variables. When creating a custom dealloc method, do not call the [super dealloc] method. This will be done for you and is enforced by the compiler.
