ios - Cookie sharing between multiple WKWebViews

Question

I create a few WkWebViews in my app, but when cookies are set for one webview, they do not take effect in the other ones (i.e. the other webviews do not pass the same cookie back to the server). How can I get them to all use the same cookie storage?

Answer 1

Got this working by using the same WKProcessPool for all the webviews.

First create a process pool once somewhere:

processPool = [[WKProcessPool alloc] init];

Then use it when creating WKWebviews. The pool must be set in the init method, not afterwards.

WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];
config.processPool = processPool;
webview = [[WKWebView alloc] initWithFrame:frame configuration:config];
