推荐答案

在iOS中确定用户代理的一种更简单的方法是直接从 UIWebView 使用此SO帖子的已接受答案。引用该答案：

A simpler way to ascertain the user agent in iOS is to get it directly from a UIWebView using the accepted answer to this SO post. To quote that answer:

解决方案是创建一个UIWebView，然后使用javascript来提取用户代理。

The solution was to create a UIWebView and then just use javascript to pull out the user agent.

UIWebView* webView = [[UIWebView alloc] initWithFrame:CGRectZero];
NSString* secretAgent = [webView stringByEvaluatingJavaScriptFromString:@"navigator.userAgent"];
