Question

I have a single image view, and I set other image views on it and put them in different locations. I want to apply FLIP ANIMATION on mage view. How can do it? when if(i==1) then my imageview is flipped. img1 is my image view and I want to identify it. I allocate 52 images in `imagearr

My code:

-(void)setCards
{

    int k=0;
    CGFloat dx = self.view.frame.size.width/2;
    CGFloat dy = self.view.frame.size.height/2;

    int cnt = [imagearr count];


    for (int j=1; j<3; j++)            // Number of cards
    {
        for (int i=1; i<5; i++)         // Number of players
        {
            int rnd = (arc4random() % cnt)-1;   
            UIImage *img = [imagearr objectAtIndex:rnd];
            UIImageView *img1 = [[UIImageView alloc] initWithImage:img];

            CGRect frame = img1.frame;
            frame.size.width = frameX;
            frame.size.height = frameY;
            [img1 setFrame:frame];
            [img1 setTag:k+i];

            [UIView beginAnimations:@"Move" context:nil];
            [UIView setAnimationDuration:0.50];
            if (i==1)
            {
                [img1 setCenter:CGPointMake(dx+100, dy+(j*15))];

            }
            if (i==2) 
            {
                [img1 setCenter:CGPointMake(dx+(j*15), dy+60)];
            }
            if (i==3) 
            {
                [img1 setCenter:CGPointMake(dx-130, dy-(j*15))];
            }
            if (i==4) 
            {
                [img1 setCenter:CGPointMake(dx-(j*20), dy-95)];
            }

            [self.view addSubview:img1];
            [UIView commitAnimations];
            [img1 release];

        }
        k=k+10;      
    }


}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{ 
    UITouch *touch = [[event allTouches] anyObject];
    int t = [touch view].tag;


}

I still can’t identify a specific imageview. Please help me to solve this problem.

I think you should take a look at the Apple sample project GeekGameBoard. It implements a solitaire game and you will be able to learn how to select CALayers* representing cards, drag them around, and have them interact with each other.

*Which will be both easier and probably better from a performance perspective than using views.
