Question

self.nflWebView = [[WKWebView alloc] initWithFrame:self.view.bounds];
self.nflWebView.backgroundColor = [UIColor clearColor];
self.nflWebView.opaque = NO;
[[self nflWebView] setDelegateViews: self];
self.nflWebView.tag = 10000;
[self.nflWebView loadHTMLString:html baseURL:[NSBundle mainBundle].bundleURL];
[self.view addSubview:self.nflWebView];

我还尝试了另外一些事情：

- (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script
{
NSLog(@"stringByEvaluatingJavaScriptFromString");
NSLog(@"script :%@",script);
__block NSString *resultString = nil;
__block BOOL finished = NO;
WKWebView *obj_wkwebview=[[WKWebView alloc]init];
    [obj_wkwebview evaluateJavaScript:script completionHandler:^(id result, NSError *error) {
        if (error == nil) {
            if (result != nil) {
                resultString = [NSString stringWithFormat:@"%@", result];
            }
        } else {
            NSLog(@"evaluateJavaScript error : %@", error);
        }
        finished = YES;
    }];

    while (!finished)
    {
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
    }

return resultString;
}

它给出错误。

Error Domain=WKErrorDomain Code=4 "A JavaScript exception occurred" UserInfo=0x170c788c0 {NSLocalizedDescription=A JavaScript exception occurred}

简单的html内容正在加载成功但是没有加载带有javascript的html。

我做了很多谷歌搜索，但没有成功。如果你有任何其他方法来做这件事，请建议我。提前谢谢。

我想在WKWebview中加载包含java脚本的html内容
