Cocoa webview UserAgent "webkit-legacy" issue

I've created simple sample application and fixed this issue. I've provided same user agent, as in Safari. After that, Shared Photos work as expected.

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {    self.webView.customUserAgent = @"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/601.2.7 (KHTML, like Gecko) Version/9.0.1 Safari/601.2.7";    self.webView.mainFrameURL = @"https://messenger.com";}

After that, I compare user agents:

Original WebView user agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/600.8.9 (KHTML, like Gecko)

Safari user agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/601.2.7 (KHTML, like Gecko) Version/9.0.1 Safari/601.2.7

So, looks like I need to change only last part of User Agent. Like that:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {    self.webView.applicationNameForUserAgent = @"Safari/601.2.7";    self.webView.mainFrameURL = @"https://messenger.com";}

With this code, Shared Photos also works. Unfortunately, it doesn't work with other applicationNameForUserAgent values I've tried.

As promised, here's the answer.

I added this function in the ViewController class.

func webView(sender: WebView!, didFinishLoadForFrame frame: WebFrame!) {    webView.stringByEvaluatingJavaScriptFromString("document.body.className = 'safari webkit mac x1 Locale_en_US _z4_';")}

Pretty simple, but it's working perfectly fine.

I still have some problems with the app itself (e.g. Download image button doesn't trigger file explorer dialog), but basic functions like

• send/receive messages
• view shared pictures

work just fine.

I'm planning on working on this for

• download image
• notification

If you are interested in helping me out, please comment!

Thanks all for your help :)
