How to goBack to startpoint in a WKWebView History

I'm trying to find a way to jump backwards to the startpoint in a WKWebView History.

Let's say i have a Main/Start-Page (WKWebView init) with a Link to google.com.

So i'm clicking at the Link and next at google.com i click another link maps.google.com. So i'm 2 steps away from my start-page.

How can i jump back directly to the Main/Startpage without reload or reinit the WKWebView ?

I have tried the following implementation but with no success: 

-(void)backNavigationToStart{
    if([vuMain canGoBack]){
        WKBackForwardList *list = [vuMain backForwardList];
        if(list && list.backList){
            WKBackForwardListItem *item = [list itemAtIndex:0];
            [vuMain goToBackForwardListItem:item];
        }
    }
}
Solution

  • Note the meaning of the index argument to -itemAtIndex:

    “Index of the desired list item relative to the current item: 0 for the current item, -1 for the immediately preceding item, 1 for the immediately following item, and so on.” https://developer.apple.com/library/ios/documentation/WebKit/Reference/WKBackForwardList_Ref/index.html#//apple_ref/occ/instm/WKBackForwardList/itemAtIndex:

    Use an appropriate negative index, or use the first item in backList.
