iOS笔记--多点触碰的时候如何获取其中的某一次点击事件

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

    NSInteger i=0;

    for (UITouch *touch in touches) {

        UIImageView *imageview=[[UIImageView alloc]initWithImage:self.images[i]];

        

        

        CGPoint location=[touch locationInView:self.view];

        [imageview setCenter:location];

        [self.view addSubview:imageview];

        i++;

    }

}
