UIWebView iOS5更改用户代理 [英] UIWebView iOS5 changing user-agent

问题描述

如何在iOS 5中更改UIWebView的用户代理？

How can I change the user-agent of UIWebView in iOS 5?

我到目前为止做了什么：
使用委托回调，拦截NSURLRequest，创建一个新的url请求并设置它的用户代理作为任何我想要的，然后下载数据，并重新加载UIWebView与loadData：MIMEType：....。

What I have done so far: Using the delegate call back, intercept the NSURLRequest, create a new url request and set it's user-agent as whatever I want, then download the data and reload the UIWebView with "loadData:MIMEType:....".

问题：
这会导致无限递归，其中我加载数据，调用委托返回， ....

Problem: This causes infinite recursion, where I load the data, which calls the delegate back, which intern calls the delegate....

这里是委托方法：

- (BOOL)webView:(UIWebView *)aWebView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {



    dispatch_async(kBgQueue, ^{
        NSURLResponse *response = nil;
        NSMutableURLRequest *newRequest = [NSMutableURLRequest requestWithURL:[request URL]];
        NSDictionary *headers = [NSDictionary dictionaryWithObject:
                                 @"custom_test_agent" forKey:@"User-Agent"];
        [newRequest setAllHTTPHeaderFields:headers];
        [self setCurrentReqest:newRequest];
        NSData *data = [NSURLConnection sendSynchronousRequest:newRequest 
                                             returningResponse:&response 
                                                         error:nil];
        dispatch_sync(dispatch_get_main_queue(), ^{
            [webView loadData:data 
                     MIMEType:[response MIMEType] 
             textEncodingName:[response textEncodingName] 
                      baseURL:[request URL]];
        });
    });

    return YES;
}

推荐答案

更改UserAgent应用程序启动时运行此代码一次：

Change the "UserAgent" default value by running this code once when your app starts:

NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"Your user agent", @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];  

编辑：我使用这个非常成功，但想添加更多的细节。要获取用户代理，您可以启用开发人员菜单，设置用户代理，然后连接到此网站，以便为您打印出来： WhatsMyAgent 。同样，你可以使用任何类型的移动设备连接，并得到它的方式。 BTW这仍然工作很好在iOS7 +

I have used this with great success, but want to add additional details. To get a user agent, you can enable the "Developer" menu, set the user agent, and then connect to this site to get it printed out for you: WhatsMyAgent. Likewise you can connect using any kind of mobile device, and get it that way too. BTW this is still working just fine in iOS7+
