ios - iOS：如何在 WKWebView 中加载本地文件（不在包中）？

Question

我想使用 WKWebView（不是 UIWebView）并在其中加载一些 html 文件。我准确地说我在 info.plist 中将 ArbitraryLoads 设置为 YES。

（有关信息，它适用于模拟器但不适用于设备）。

<key>NSAppTransportSecurity</key>
<dict>
      <key>NSAllowsArbitraryLoads</key>
        <true/>
</dict>

这是我的代码：

       WKWebViewConfiguration *theConfiguration = [[WKWebViewConfiguration alloc] init];
    [theConfiguration setMediaPlaybackAllowsAirPlay:YES];
    [theConfiguration setAllowsInlineMediaPlayback:YES];
    [theConfiguration setAllowsPictureInPictureMediaPlayback:YES];
    [theConfiguration setAllowsAirPlayForMediaPlayback:YES];
       [theConfiguration.preferences setValue:@YES forKey:@"allowFileAccessFromFileURLs"];
[theConfiguration setValue:@YES forKey:@"_allowUniversalAccessFromFileURLs"];
       self.webView.navigationDelegate = self; 
       self.webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:theConfiguration];

      NSURL *nsurl2 = [NSURL fileURLWithPath:[[[self documentsDirectory] stringByAppendingPathComponent:user_appli] stringByAppendingPathComponent:@"index.html"]];//locally


 [self.webView loadFileURL:nsurl2 allowingReadAccessToURL:nsurl2]; //=> doesn't work  

 [self.webView loadRequest:[NSURLRequest requestWithURL:nsurl2]]; //=> doesn't work

提前致谢。

您必须使用目录的根目录才能允许 webview 读取文件

NSURL *nsurl = [NSURL fileURLWithPath:[[[self documentsDirectory] stringByAppendingPathComponent:user_appli] stringByAppendingPathComponent:@"index.html"]]; //locally
NSURL *readAccessToURL = [[nsurl URLByDeletingLastPathComponent] URLByDeletingLastPathComponent];

[self.webView loadFileURL:nsurl allowingReadAccessToURL:readAccessToURL];
