来自Parse Not Images On iOS 9的图像

Question

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;
}

这可能是由于iOS 9的SSL要求.由于Parse不对文件使用HTTPS,因此无法正确下载.设置info.plist以包含这样的密钥,这会关闭SSL要求......当然:风险自负:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
        <key>NSExceptionDomains</key>
        <dict>
            <key>files.parsetfss.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>
                <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <key>NSTemporaryExceptionMinimumTLSVersion</key>
                <string>TLSv1.1</string>
            </dict>
        </dict>
    </dict>
