开门动画

使用方式：

DoorView *doorView = [[DoorView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)                                                door:[UIImage imageNamed:@"Default.png"]];[doorView setDelegate:self];[doorView openDoor];[self.view addSubview:doorView];[doorView release];- (void)doorView:(DoorView *)doorView didDoorOpend:(BOOL)opend{    if(opend)    {        NSLog(@"Door Opend\n");    }}
