change user-agent for good

I have been able to change the user-agent by using

- (BOOL)webView:(UIWebView *)webView2 shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

NSMutableURLRequest *req = (NSMutableURLRequest *)request;
NSString *versionString = [[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*)kCFBundleVersionKey];

NSLog(@"user agent = %@", [req valueForHTTPHeaderField: @"User-Agent"]);

if ([req valueForHTTPHeaderField:@"User-Agent"] != NULL) {

    [req setValue:[NSString stringWithFormat:@"%@ %@", versionString, [req valueForHTTPHeaderField:@"User-Agent"]] forHTTPHeaderField:@"User-Agent"];
    NSLog(@"user agent = %@", [req valueForHTTPHeaderField: @"User-Agent"]);

   return YES
    }
}

But when I go to this website on the device http://whatsmyuseragent.com/ my user-agent hasn't changed. Is there a way to change the user-agent for good?

After playing around for a really long time, I discovered that you can change the User Agent without rooting. Not sure if this helps you if you are building an app.

You can change the value of the user agent when doing "manual" NSURLRequests but I don't think you can change them in a UIWebView.

Reason being, the values that are passed into the method you show above are not mutable -- you can't change them and expect that the rest of the application will "take" the modifications. Honestly, I'm surprised that casting a NSURLRequest to its mutable variant and then changing it didn't cause your app to crash.

I have noticed that the simulator reports nil when testing at times. I'm not sure if this is intentional or on purpose.

You cannot change the user-agent displayed by Safari, only the one used by your own application.
