UICollectionView 单元格在点击时更改背景 [英] UICollectionView cell change background while tap

问题描述

是否有可能仅在点击元素时更改 UICollectionView 的背景颜色.我试过了:

Is there a possibility to change the background color of UICollectionView only while the element is tapped. I have tried:

-(void) collectionView:(UICollectionView *)collectionView didHighlightItemAtIndexPath:(NSIndexPath *)indexPath{
    //change color when tapped
}

-(void)collectionView:(UICollectionView *)collectionView didUnhighlightItemAtIndexPath:(NSIndexPath *)indexPath{
    //change back on touch up 
}

但结果是，只有当我保持手指更长的时间时，我才能看到变化.UITableViewCell 方法 willSelectItemAtIndexPath: 中是否有类似的东西?

But the result is that I can see the change only when i keep my finger for a bit longer time. Is there some similar stuff like in UITableViewCell method willSelectItemAtIndexPath:?

您遇到的延迟可能与情节提要中的延迟内容接触"复选框有关.

The delay your are experiencing is probably related to the "Delay content touches" checkbox in the storyboard.

尝试取消选中它.
