UIWebView Clear All Cookies

Question

I'm working on making a mini browser using a UIWebView.

I'd like to provide users with a way to remove all cookies from all sites - similar to in the Chrome app where you can clear cache, etc.

What's the best way to accomplish this in a UIWebView?

Here's one idea I had:

NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in [storage cookies]) {
   [storage deleteCookie:cookie];
}
[[NSUserDefaults standardUserDefaults] synchronize];

Sort of, that's what I reference. But I want to let them clear everything - cache and cookies — Tom Hammond, Mar 06 '17 at 18:32
@TomHammond Sidenote, you should not use UIWebView, as suggested by Apple multiple times, use a WKWebView instead. — , Mar 06 '17 at 18:45
@matt Not sure if you saw, but you can hammer as multiple duplicates now. See above where I've closed this question as both a dupe of one which shows how to clear cookies, and one which shows how to clear the cache. — JAL, Mar 06 '17 at 18:47
Technically the latter doesn't work as it's in Swift and I wanted Objective-C, but I got the answer I needed. Thanks guys! — Tom Hammond, Mar 06 '17 at 18:54

Use this for clearing the cookies as well as the cache.

    URLCache.shared.removeAllCachedResponses()
    URLCache.shared.diskCapacity = 0
    URLCache.shared.memoryCapacity = 0

    webView.stringByEvaluatingJavaScript(from: "localStorage.clear();")
    let cookieJar = HTTPCookieStorage.shared
    for cookie in cookieJar.cookies! {
        cookieJar.deleteCookie(cookie)
    }
    UserDefaults.standard.synchronize()
