Why I can't save WKWebView to [NSUserDefaults standardUserDefaults]?

Question

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

[prefs setObject:self.webView forKey:@\"webView\"];

The code above is made to save

Answer 1

In case you really want the webview from user default, here is a choice.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
[prefs setObject:[NSKeyedArchiver archivedDataWithRootObject:self.webView] forKey:@"webView"];

// get it back from user default
NSData *data = [prefs objectForKey:@"webView"];
self.webView = [NSKeyedUnarchiver unarchiveObjectWithData:data];
