objective-c - 从多个 ImageView 中识别特定 ImageView

Question

我有一个 ImageView ，我在它上面设置了其他 ImageView 并将它们放在不同的位置。我想在 mage view 上应用 FLIP ANIMATION。怎么办？当 if(i==1) 然后我的 imageview 被翻转。 img1 是我的 ImageView ，我想识别它。我在`imagearr中分配了52张图片

我的代码:

-(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;


}

我仍然无法识别特定的 ImageView 。请帮我解决这个问题。

为单个 imageView 设置标签是最好的方法。使用标签，您甚至可以检测放置在表格 View 单元格内的多个图像，并设置用于选择单个标签的操作。
