Question

I’d like to write an iOS unit test for a dealloc method that (basically) removes the object as the delegate of another object.

- (void) dealloc {
    someObject.delegate = nil;
}

However I can’t call dealloc directly when using ARC. What would be the best way to write this unit test?

Answer 1

Assign an instance to a weak variable:

MyType* __weak zzz = [[MyType alloc] init];

The instance will be dealloced right away.

Alternatively, you can disable ARC on your unit test file and call dealloc.
