UICollectionView的单选

大家好，又见面了，我是你们的朋友全栈君。

//点击选定

– (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath

{

        JFCollectionViewCell *cell = (JFCollectionViewCell *)[collectionView cellForItemAtIndexPath:indexPath];

        cell.backgroundColor=[UIColor colorWithRed:27/255.0 green:166/255.0 blue:152/255.0 alpha:1];

        cell.topLabel.textColor=[UIColor whiteColor];

        cell.bottomLabel.textColor=[UIColor whiteColor];

        NSLog(@”第%ld区，第%ld个“,(long)indexPath.section,(long)indexPath.row);

}

//取消选定

-(void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath{

    JFCollectionViewCell *cell = (JFCollectionViewCell *)[collectionView cellForItemAtIndexPath:indexPath];

    cell.backgroundColor=[UIColor whiteColor];

    cell.topLabel.textColor=[UIColor colorWithRed:27/255.0 green:166/255.0 blue:152/255.0 alpha:1];

    cell.bottomLabel.textColor=[UIColor blackColor];

     NSLog(@”1第%ld区，1第%ld个“,(long)indexPath.section,(long)indexPath.row);

}
