我解决了查看下面的选定答案！

我一直在努力寻找导致OSX Cocoa应用程序的WebView与Safari行为不同的原因。事实证明，用户代理是不同的（很明显吗？），而我访问的网站不知道该如何处理。

令人惊讶的是，它是https://messenger.com（facebook聊天）。

问题是它没有在屏幕上显示图片。它会加载，但实际上不会显示。看看这个..

如果您查看我编号为“ 2”的区域，则会看到空白区域。我没有审查。它只是空的。

So here's my original question link: Simple Swift Cocoa app with WebKit: Upload picture doesn't work

I solved the first issue (thanks to the answers :D), but second issue persists.

Shared picture does not show up - I labeled as 2 in the picture.

again, from other browsers or released apps, it shows the pictures that I shared with participants like below. (of course I censored the pictures)

To debug this, I opened the Inspect Element and I found this out.

<body class=" webkit-legacy webkit mac x1 body_textalign Locale_en_US _z4_" dir="ltr">

When I did load the exact same page from Safari, I'd see this:

<body class="safari webkit mac x1 body_textalign Locale_en_US _z4_" dir="ltr">

So I decided to replace that line from WebView of my app, and viola! it works! so...

TLDR: How do I make this work every time I load the view?

I tried to find some methods to set up my user agent to Safari, but I can't get this to work. Any suggestion please?

如所承诺的，这就是答案。

我在ViewController类中添加了此功能。

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

很简单，但是工作得很好。

我仍然对应用程序本身有一些问题（例如，“下载图像”按钮不会触发文件浏览器对话框），但是诸如
