Question

我做谷歌太多找不到但却找不到我想要的东西。我有file.png，file1.jpg，file2.pdf，file.txt和file.doc，我想在一个文件中预览这个文件 UIWebView或UIScrollView。请帮帮我怎么办？提前谢谢。

对于通过HTML sting显示的示例图像，此图像在捆绑文件中。 webview中的HTML sting加载遵循此行为！就像你需要用所有文件创建html sting并显示

 NSString *imageFileName = @"images";
    NSString *imageFileExtension = @"jpg";
    NSString *imagePath = [[NSBundle mainBundle] pathForResource:imageFileName ofType:imageFileExtension];
    NSString *imgHTMLTag = [NSString stringWithFormat:@"<img src=\"file://%@\" />", imagePath];
    [myWebView loadHTMLString:imgHTMLTag baseURL:nil];`enter code here`

一旦检查

 NSString *imageFileName = @"images";
    NSString *imageFileExtension = @"jpg";
    NSString *imagePath = [[NSBundle mainBundle] pathForResource:imageFileName ofType:imageFileExtension];
    NSString *pdfPath = [[NSBundle mainBundle] pathForResource:@"Disciplinary" ofType:@"pdf"];
    NSString *imgHTMLTag = [NSString stringWithFormat:@"<html><body><img src=\"file://%@\" /></body><body><img src=\"file://%@\" /></body><body><img src=\"file://%@\" /></body></html><body><object id =\"PDFObj\" data=\"file://%@\"/ type=\"application/pdf\" width = \"1000\" height = \"10000\"></body>", imagePath,imagePath,pdfPath,pdfPath];
    [img loadHTMLString:imgHTMLTag baseURL:nil];

如何在UIWebView / UIScrollView中显示多个具有不同文件扩展名的文件？
