[transparentView addSubview:self];

float x = (int)(transparentView.bounds.size.width - self.bounds.size.width)>>1;

Create a custom transparent view then override this method

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

Add your alert view into this view and use this view as full screen view. You can use event param to calculate to know user touch inside or outside of alertview.
