How to delete all cookies of UIWebView?

3 Solutions Collect From Internet About “How to delete all cookies of UIWebView?”

According to this question, you can go through each cookie in the “Cookie Jar” and delete them, like so:

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

Just wanted to add some info regarding this.

In OS X 10.9/iOS 7 and later, you can use -resetWithCompletionHandler: to clear the cookies and cache etc. of the whole app from your sharedSession:

Empties all cookies, caches and credential stores, removes disk files,
flushes in-progress downloads to disk, and ensures that future
requests occur on a new socket.

[[NSURLSession sharedSession] resetWithCompletionHandler:^{
    // Do something once it's done.

The for-In loop with deleteCookie: sounds like modifying while enumerating a collection to me. (Don’t know, could be a bad idea?)

You could make a function inside the html of the WebView, that cleans the cookies.

If you need the cleaning to be done only once you could trigger this function with a Titanium event, only when the app starts.
