Iphone – Dragging 1 of 52 cards in UIView. Which is a better method

iphonexcode

Currently I have 52 cards UIImageViews in IB UIView.

And my objective is to drag 1 of this 52 cards into a Square, and if the the card is dropped into the Square, it will stay there. Otherwise, it will snap back it's original position.

MY question is which is a better method?

Creating a custom class NSObject and changing every card in IB into this class and using this code in the .m file.
`- (void)touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event {
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:self.superview];

self.center = location;
}
Declaring 52 IBOutlets and make them respond to the same action

i)Subsidiary question: Is there a way i do not need to declare all 52 IBOutlets?
`
Thank you in advance!

It will be best to add the cards through a for loop programmatically setting the tag of each card like x+1 to x+52, make them respond to same action and in check the frame for the matching frame of your card in -(void)touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; this is a little bit tricky but much less effort is required and the things will be much more handlable.

Hope this will give you a good idea

That looks like a very difficult way to go about doing it. I havent been coding long myself but maybe the following might help you. lets say u have a nsmutablearray called enemies and you add the new enemy object to this array when ever you create one. enemy object would be a ccnode and have a ccsprite within it called _enemySprite then do the touch

 -(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
    {

    NSSet *allTouches = [event allTouches];
    UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
    //UITouch* touch = [touches anyObject];
    CGPoint location = [touch locationInView: [touch view]];
    location = [[CCDirector sharedDirector] convertToGL:location]; 

    int arraysize = [enemies count];
    for (int i = 0; i < arraysize; i++) {


        if (CGRectContainsPoint( [[[enemies objectAtIndex:i] _enemySprite] boundingBox], location)) {

            //some code to destroy ur enemy here


        }
    }
    //  NSLog(@"TOUCH DOWN");

}

hope this helps
