我有一个PFQueryCollectionViewController填充图像,一切正常在iOS 8.xx及以下,但当我使用Xcode 7 Beta在iOS 9上运行应用程序时,所有图像都是空白的.
这是我用来从Parse中加载图像的代码 PFQueryCollectionViewController
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"Cell" forIndexPath:indexPath];
UIImageView *imageView = (UIImageView*)[cell viewWithTag:1];
if([object objectForKey:@"image"] != NULL) {
[[object objectForKey:@"image"] getDataInBackgroundWithBlock:^(NSData *imageData, NSError *error) {
UIImage *thumbnailImage = [UIImage imageWithData:imageData];
UIImageView *thumbnailImageView = [[UIImageView alloc] initWithImage:thumbnailImage];
imageView.image = thumbnailImageView.image;
}];
}
return cell;
}
和
- (PFQuery *)queryForCollection {
PFQuery *query = [PFQuery queryWithClassName:@"Class"];
...
return query;
}
