ios - 大约 10 秒后开始加载 wkwebview 白页

Question

我想加载一个远程 url 页面，但它总是在大约 10 秒后开始加载代码如下

- (UIWebView *)webView {
    if(!_webView) {
        _webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];
        _webView.scalesPageToFit = YES;
        _webView.dataDetectorTypes = UIDataDetectorTypeAll;
        _webView.delegate = self;
    }
   return _webView;
}

- (void)viewDidLoad {
   [super viewDidLoad];
   // Do any additional setup after loading the view.
   [self editNavigationBar];
   NSLog(@"viewLodLoad");
   self.view.backgroundColor = [UIColor whiteColor];
   [self loadHTML:self.pageModel.url title:self.pageModel.postUser];
   [self.view addSubview:self.webView];
}
-(void)editNavigationBar {
    [self.view addSubview:self.webView];
    NSLog(@"start Load WebView"); 
    [self loadWebView];
}


//load URL
 - (void)loadHTML:(NSString *)htmlString title:(NSString *)title
 {
    self.request = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:htmlString]];
   self.title = title;
   [self.webView loadRequest:self.request];
}

但是日志结果是....

Answer 1

为什么你把所有的 GCD 东西都放在那里？好像没必要。您应该能够将其减少到:

- (void)loadWebView {
    [self loadHTML:self.pageModel.url title:self.pageModel.postUser];
}

我打赌这会消除您的 10 秒延迟。
