如何检查UICollectionView是否有图像

您可以检查是否有图像

UIImageView

或不这样：

    
      -(BOOL) checkImages {
    for (int i=0, i<2 , i++) {
        NSIndexPath indexPath = [NSIndexPath indexPathForItem:i inSection:0];
        ADRPhotoCollectionViewCell cell = [collectionView cellForItemAtIndexPath:indexPath];
        if (cell.imageView.image == nil || CGSizeEqualToSize(cell.imageView.image.size, CGSizeZero)) {
            //there isn’t any image or the image is empty
            return NO;
        }
    }
    return YES;
}
