在iOS中以水平方式在UIWebView中閱讀PDF

Question

用於在iOS中水平讀取UIWebView PDF文件。

所以我寫了以下添加與UIScrollView水平滾動。

UIScrollView *scrollView = [[UIScrollView alloc] init];
    scrollView.contentSize = CGSizeMake(2000, 420);
    scrollView.bounces = NO;
    scrollView.alwaysBounceHorizontal = NO;
    scrollView.alwaysBounceVertical = NO;
    scrollView.backgroundColor = [UIColor whiteColor];

    [scrollView addSubview:self.spiderWeb];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"document" ofType:@"pdf"];
    NSURL *targetURL = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
    [self.spiderWeb loadRequest:request];

    [self.view addSubview:scrollView];

它什么也沒顯示。 沒有ScrollView，我可以垂直讀取UIWebView中的PDF。 我哪里錯了？
