我正在使用本地文件测试WKWebView,该文件在模拟器中工作,但它无法在设备中运行
@interface EDPresentationViewController ()<WKNavigationDelegate,WKScriptMessageHandler>
@property(nonatomic,strong)WKWebView *webView;
@property(nonatomic,strong)EDPresentationController *presentationController;
@end
@implementation EDPresentationViewController
-(void)viewDidLoad
{
[super viewDidLoad];
self.presentationController = [[EDPresentationController alloc]init];
WKWebViewConfiguration *webConfiguration = [[WKWebViewConfiguration alloc]init];
self.webView = [[WKWebView alloc]initWithFrame:self.view.frame configuration:webConfiguration];
NSURL *presentationFolder = [self.presentationController url];
NSURLRequest *request = [NSURLRequest requestWithURL:presentationFolder];
[self.webView loadRequest:request];
}
我从以下网址授予网址:
NSURL *presentationFolder = [self.presentationController url];
没问题,因为我用UIWebview测试了相同的代码并且有效!
我总是得到同样的错误:
Could not create a sandbox extension for '/'
这不起作用,我想它会在Objective-C中起作用,就像在swift中一样
iOS Webkit not working on device, but works on simulator at swift
任何想法都将不胜感激,谢谢

我发现这可能是iOS 8.1中的一个错误,可能会在8.2中修复

我已经测试过将文件移动到临时文件夹,但我没有收到任何错误,但webView只是空的。
我已经使用UIWebView测试了相同的代码(临时文件夹)并且工作正常!
另外,我试过这个:

正如我所知,这是有效的,因为css和javascript被嵌入到html中。
答案 0 :(得分:4)
尝试具有非常小的嵌入式http服务器的XWebView。它比GCDWebServer小得多。通过扩展名添加loadFileURL:allowingReadAccessToURL方法,因此您不了解服务器。

这就像一个魅力......
@interface ViewController () <WKScriptMessageHandler, WKNavigationDelegate>
...
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
WKUserContentController *controller = [[WKUserContentController alloc] init];
configuration.userContentController = controller;
[configuration.preferences setValue:@"TRUE" forKey:@"allowFileAccessFromFileURLs"];
self.webView = [[WKWebView alloc] initWithFrame:[UIScreen mainScreen].bounds configuration:configuration];
self.webView.navigationDelegate = self;
// Also if you'd have bouncing problem
self.webView.scrollView.bounces = false;
self.webView.scrollView.alwaysBounceVertical = false;
[self.view addSubview:self.webView];
NSString* productURL = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"htmlapp/home.html"];
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:productURL]];
[self.webView loadRequest:request];
