UICollectionViewCell点击高亮效果(附带效果GIF)

首先效果如下：

背景是这样的：UI上使用的是UICollectionView，所以后面会使用它的协议方法完成。

实现思路是这样的：高亮状态+点击后短时间内保持颜色变化

实现的代码参考如下：

// Cell被点击后短时间内保持颜色的变化
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {

    WSFEvaluateTagItem *cell = (WSFEvaluateTagItem *)[collectionView cellForItemAtIndexPath:indexPath];
    cell.backgroundColor = [UIColor blueColor];
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(),
^{
        cell.backgroundColor = [UIColor whiteColor];
    });
}

// 长按的情况下要实现高亮状态下的颜色保持
- (void)collectionView:(UICollectionView *)collectionView didHighlightItemAtIndexPath:(NSIndexPath *)indexPath{
    
    WSFEvaluateTagItem *cell = (WSFEvaluateTagItem *)[collectionView cellForItemAtIndexPath:indexPath];
    cell.backgroundColor = [UIColor blueColor];
}

- (void)collectionView:(UICollectionView *)collectionView didUnhighlightItemAtIndexPath:(NSIndexPath
*)indexPath{
    
    WSFEvaluateTagItem *cell = (WSFEvaluateTagItem *)[collectionView cellForItemAtIndexPath:indexPath];
    cell.backgroundColor = [UIColor whiteColor];
}

- (BOOL)collectionView:(UICollectionView *)collectionView shouldHighlightItemAtIndexPath:(NSIndexPath
*)indexPath{
    
    return YES;
}
