UICollectionView的item点击效果需要自己实现,系统提供了
//高亮效果
- (void)collectionView:(UICollectionView *)collectionView didHighlightItemAtIndexPath:(NSIndexPath *)indexPath;
//非高亮效果
- (void)collectionView:(UICollectionView *)collectionView didUnhighlightItemAtIndexPath:(NSIndexPath *)indexPath;
//点击item,cell上图片改变
-(void) collectionView:(UICollectionView *)collectionView didHighlightItemAtIndexPath:(NSIndexPath *)indexPath
{
QFTIconCollectionCell *cell = (QFTIconCollectionCell *)[collectionView cellForItemAtIndexPath:indexPath];
NSString *imageName = [NSString stringWithFormat:@"select%@",[self.iconArray objectAtIndex:indexPath.item]];
cell.iconImage.image = [UIImage imageNamed:imageName];
}
//点击放开item,cell上图片复原
- (void)collectionView:(UICollectionView *)collectionView didUnhighlightItemAtIndexPath:(NSIndexPath *)indexPath
{
QFTIconCollectionCell *cell = (QFTIconCollectionCell *)[collectionView cellForItemAtIndexPath:indexPath];
NSString *imageName = [self.iconArray objectAtIndex:indexPath.item];
cell.iconImage.image = [UIImage imageNamed:imageName];
}
主:UITableView也有这样两个方法,可以根据需求适当选用
