UIWebView不加载URL [英] UIWebView does not load the URL

问题描述

在 UIWebView 中加载网址时，我遇到的问题非常小。
我有一个 UIButton ，点击它，我添加 UIView ，其中包含 UIWebView ， UIButton & 标题栏。使用的代码如下 -

I have very small problem while loading the URL in UIWebView. I have one UIButton, on clicking of it, I add the UIView which contains UIWebView, UIButton & Title bar. Code used is as follows -

    [self.view addSubview:vwOnline];
    vwOnline.bounds = self.view.bounds;

    //Load webview
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@", objWine.strOnlineURL]];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [wbvwOnline loadRequest:request];

- (void)webViewDidStartLoad:(UIWebView *)webView
{
    //Show activity indicator
    [indicator startAnimating];
}

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    //Remove Activity indicator
    [indicator stopAnimating];
    [indicator removeFromSuperview];
}

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
    NSLog(@"Error - %@", error);

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Find A Vino" message:@"Error while loading request." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alert show];
    alert.tag = 1;

    //Remove Activity indicator
    [indicator stopAnimating];
    [indicator removeFromSuperview];
}

通过上面的代码，大部分时间是 UIWebView 不会加载我在对象 objWine.strOnlineURL 中传递的 URL 。如果我点击后退按钮&再次单击按钮加载 URL ，它进入 - （void）webView：（UIWebView *）webView didFailLoadWithError：（NSError *）错误 UIWebView 的委托方法。
如果有人知道解决方案，那么请帮助我。

By doing above code, most of times the UIWebView does not loads the URL which I passed in the object objWine.strOnlineURL. If I clicked the back button & again clicked on the button to load the URL, it goes into the - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error delegate method of UIWebView. If anyone knows the solution, then please help me.

推荐答案

当你回去时，请求零并将 htmlstring 加载到 webview 。还有一件事，删除 [指标removeFromSuperview]; 行

when you are going back, make request to nil and load empty htmlstring to webview. One more thing, remove [indicator removeFromSuperview]; line from

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error 
-(void)webViewDidFinishLoad:(UIWebView *)webView
