Question

我正在创建一个程序，其中图像显示在集合视图网格中，当我点击/点击特定图像时，它应该在另一个滚动视图中打开。我正在动态地在集合视图中创建单元格。有谁对此有任何想法？提前谢谢。

Answer 1

使用点击手势

 UITapGestureRecognizer *PressRecognizer1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handlePress:)];
            [PressRecognizer1 setNumberOfTouchesRequired:1];
             [imageview addGestureRecognizer:PressRecognizer1];

在此方法中编写代码

-(void)handlePress:(UITapGestureRecognizer*)PressRecognizer {

    NSLog(@"working");

   //Add your code here for click on particular image

}

Answer 2

您需要实现以下UICollectionViewDelegate方法

- (void)collectionView:(UICollectionView *)collectionView
didSelectItemAtIndexPath:(NSIndexPath *)indexPath

当用户点击某个项目时，将调用该方法。

不要忘记设置委托。

Answer 3

为什么不简单地添加图片并使用UIButton？

[button setBackgroundImage:[UIImage imageNamed:@"img.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(callNewController:) forControlEvents:UIControlEventTouchUpInside];

Answer 4

您需要使用didSelectItemAtIndexPath委托方法。

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath 
{
    // TODO: Here you need to allocate the next view and pass the image then show the view
}
