I have a business need to be able to customize the UserAgent for an embedded UIWebView. (For instance, I'd like the server to respond differently if, say, a user is using one version of the app versus another.)
Is it possible to customize the UserAgent in the existing UIWebView control the way it is, say, for an embedded IE browser in a Windows app?
It should work with an NSMutableURLRequest as Kuso has written.
NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: @"http://www.google.com/"]];
[urlRequest setValue: @"iPhone" forHTTPHeaderField: @"User-Agent"]; // Or any other User-Agent value.
You'll have to use NSURLConnection to get the responseData. Set the responseData to your UIWebView and the webView should render:
[webView loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)encodingName baseURL:(NSURL *)baseURL];
Taking everything this is how it was solved for me:
- (void)viewDidLoad {
NSURL *url = [NSURL URLWithString: @"http://www.amazon.com"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:@"Foobar/1.0" forHTTPHeaderField:@"User-Agent"];
[webView loadRequest:request];
}
Thanks Everyone.
Using @"User_Agent" simply causes a custom header to appear in the GET request.
User_agent: Foobar/1.0\r\n
User-Agent: Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_1_2 like Mac OS X; en-us) AppleWebKit/528.18 (KHTML, like Gecko) Mobile/7D11\r\n
The above is what appears in the dissected HTTP packet, essentially confirming what Sfjava was quoting from that forum. It's interesting to note that "User-Agent" gets turned into "User_agent."
Apple will soon stop accepting apps with UIWebView. Find below for how you could change the user agent in WKWebView.
let config = WKWebViewConfiguration()
config.applicationNameForUserAgent = "My iOS app"
webView = WKWebView(frame: <the frame you need>, configuration: config)
