LogOut from Facebook using childBrowser and PhoneGap in IPhone

Question

I'm working on PhoneGap and have a FBConnect. Using childBrowser and the blog'http://www.pushittolive.com/post/1239874936/facebook-login-on-iphone-phonegap', I have logged in to the App. But could not logout from the app. It's autosigned in for each time I login.

Can any one tell me how to logout from the FBConnect using Childbrowsern PhoneGap?

Answer 1

Try this.

Add this function to ChildBrowserCommand.m

-(void) deleteCookies:(NSMutableArray*)arguments withDict:(NSMutableDictionary*)options{
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage]; 
    for (NSHTTPCookie *each in [cookieStorage cookies]) {
            [cookieStorage  deleteCookie:each];
    }
}

Add this to Childbrowser.js

ChildBrowser.prototype.LogOut = function()
{
     PhoneGap.exec("ChildBrowserCommand.deleteCookies");
}

Add this to FBConnect.js

FBConnect.prototype.Logout = function()
{
   window.plugins.childBrowser.LogOut();    
}

At your page add this code to logout button on click

function Logout()
{
  var fb=FBConnect.install();
  fb.Logout();
}

Enjoy.
