UICollectionViewCell點擊高亮效果(附帶效果GIF)

首先效果如下：

背景是這樣的：UI上使用的是UICollectionView，所以后面會使用它的協議方法完成。

實現思路是這樣的：高亮狀態+點擊后短時間內保持顏色變化

實現的代碼參考如下：

// Cell被點擊后短時間內保持顏色的變化
- (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];
    });
}

// 長按的情況下要實現高亮狀態下的顏色保持
- (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;
}
