UICollectionView中放置imageView各種操作并不會導(dǎo)致什么問題, 但是這個imageView如果是animation的效果, 那么就會詭異的消失, 不知道是否算bug, 這時候需要給imageView和collectionView分別配置

修復(fù)方式

imageView 配置

//在uiimageview的內(nèi)部設(shè)置高亮動畫內(nèi)容, 可以設(shè)置為默認(rèn)相同的images地址

[self setHighlightedAnimationImages:images];

collectionView 配置

//沒錯, 就是在選中, 取消選中, 高亮, 取消高亮下都讓cell的動畫再開始播放

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell * cell = (CustomCell *)[collectionView cellForItemAtIndexPath:indexPath];
    if(cell){
        [cell.imageView startAnimating];
    }
}

-(void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell * cell = (CustomCell *)[collectionView cellForItemAtIndexPath:indexPath];
    if(cell){
        [cell.imageView startAnimating];
    }
}

-(void)collectionView:(UICollectionView *)collectionView didHighlightItemAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell * cell = (CustomCell *)[collectionView cellForItemAtIndexPath:indexPath];
    if(cell){
        [cell.imageView startAnimating];
    }
}
-(void)collectionView:(UICollectionView *)collectionView didUnhighlightItemAtIndexPath:(NSIndexPath *)indexPath{
    CustomCell * cell = (CustomCell *)[collectionView cellForItemAtIndexPath:indexPath];
    if(cell){
        [cell.imageView startAnimating];
    }
}

屏蔽方式

可以將collectionView的cell交互禁掉

layerCollection.allowsSelection = false;
