Answer 1

You could just use a flag (aka a BOOL variable) that lets you know in either methods (A or B) if the other one has completed yet. Something on the lines of this:

- (void) methodA
{
    // implementation

    if (self.didFinishFirstMethod) {
        [self finalMethod];
    } else {
        self.didFinishFirstMethod = YES;
    }
}


- (void) methodB
{
    // implementation

    if (self.didFinishFirstMethod) {
        [self finalMethod];
    } else {
        self.didFinishFirstMethod = YES;
    }
}


- (void) finalMethod
{
    // implementation
}

Cheers!
