基本的に、特定のファイル拡張子をクリックすると新しいView Controllerが開き、画像が表示されるWebViewがあります。iOS 6 では、[webView stopLoading] は、webview を停止してビュー コントローラーを渡すのに完全に機能しました。

iOS 7 にアップグレードしてから、これは 1 回か 2 回しか機能しませんが、その後、webview で上記の画像を開き、View Controller を渡します。

以下は、以前に IOS 6 で作業していたものです。

どんな助けでも大歓迎です。

だから私はこれをうまく機能させることができたと思います。いくつかの再コーディングと調整により、私はこれを思いつきました：

        NSURL *imageURl = [request URL];
        NSString *imageFileExtension = [[imageURl absoluteString] pathExtension];

        NSSet *supportedFileExtensions = [NSSet setWithObjects:@"png", @"jpg", @"jpeg", @"gif", @"bmp", @"pdf", @"raw", nil];

        if ([supportedFileExtensions containsObject:[imageFileExtension lowercaseString]]) {

            [webView stopLoading];

            //Image manager
            [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

            WebImageViewController * vc = [[WebImageViewController alloc] initWithURL:[request URL]];
            [self.navigationController pushViewController:vc animated:YES];
            [vc release];
