ios – 在UIScrollview中水平显示pdf文件

在使用UIWebView的pdf文件中,我需要水平滚动而不是垂直滚动.我在表单中创建了UIScrollView：

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

现在将uIWebView添加到UIScrollView中

[scrollView addSubview:webView];

它不显示pdf文件,但如果我给出这样的代码

[self.view addSubview:webView];

现在它显示文件,但它垂直滚动

我需要让它水平滚动请帮助我.提前致谢.

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:webView];

[self.view addSubview:scrollView];
