有没有办法如何在不重新实例化的情况下如何在iOS的wkwebview上设置UserAgent每个URL？

Question

I want to set UserAgent each url on wkwebview. But i can't find.

let userAgentStr = "XXXXXXXXXXXXXXXXX"
    let dic:NSDictionary = ["UserAgent":userAgentStr]
    NSUserDefaults.standardUserDefaults().registerDefaults(dic as [NSObject : AnyObject])
    NSUserDefaults.standardUserDefaults().synchronize();

if above source is,my app will not be able to change UserAgent as long as i set nil wkwebview.

I don't want to re-instaciate wkwebview when i want to change useragent.

are there way how to set UserAgent each url on wkwebview of iOS without re-instanciating?

Answer 1

This was not possible with iOS 8 but on iOS 9 there actually is a customUserAgent on the WKWebView object. So you can just set that and it will be set for every connection the WKWebView makes.
