UICollectionview cell selection

UICollectionview cell selection

UICollectionview cell 선택시 효과를 주는 방법입니다.

저는 셀 선택시 테두리에 색을 입히는 방법을 썼습니다.

int selectedCellIndex; 선언

- (UICollectionViewCell*)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath

{

   

    MiddleCell* cell = (MiddleCell *)[collectionView dequeueReusableCellWithReuseIdentifier:@"MiddleCell" forIndexPath:indexPath];

    

    if (selectedCellIndex == indexPath.row) {

        

        cell.layer.borderWidth = 2.0;

        cell.layer.borderColor = [UIColor colorWithRed:0.965 green:0.427 blue:0.196 alpha:1.000].CGColor;

        

    }

    else

    {

        cell.layer.borderWidth = 0.0;

    }

return cell;

}

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

{

    selectedCellIndex = (int)indexPath.row;

}

셀 선택 후 collectionview reloadData 하는것도 잊지마세요.
