ios - 如何更改 UICollectionView 的选定单元格的图像？

Question

我正在尝试使用此代码，但它不起作用：

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
printf("Selected View index=%d",indexPath.row);

UICollectionViewCell *cell = [self.collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
cell.selectedBackgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"blue_s.png"]];
//[self.collectionView reloadData];
}

如何更改在 aUIImage中选择UICollectionViewCell的UICollectionView？

Answer 1

确实使用了这个

 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [self.collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"yellow_seat.png"]];
cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"blue_s.png"]];
return cell;
}
