iOS ShareKit Cancel button is not working with Xcode 4.2

问题

The iOS Sharekit working with previous Xcode but will 4.2 it's not working anymore, When I hit the Cancel button it goes to this routine

Inside the SHK.m

  - (void)hideCurrentViewControllerAnimated:(BOOL)animated
  {


if (isDismissingView)
return;

if (currentView != nil)
{
    // Dismiss the modal view
    if ([currentView parentViewController] != nil)
    {
        self.isDismissingView = YES;
        [[currentView parentViewController] dismissModalViewControllerAnimated:animated];
    }

    else
        self.currentView = nil;
}

}

I stepped the code and it just hit if (isDissmissingView) and it just return.
So, I manually inserted the code

   [[currentView parentViewController] dismissModalViewControllerAnimated:animated];

to the top of the routine but this doesn't do anything.

I also includes some other codes for reference

  - (void)showViewController:(UIViewController *)vc

{

  if (rootViewController == nil)
{
    // Try to find the root view controller programmically

    // Find the top window (that is not an alert view or other window)
    UIWindow *topWindow = [[UIApplication sharedApplication] keyWindow];
    if (topWindow.windowLevel != UIWindowLevelNormal)
    {
        NSArray *windows = [[UIApplication sharedApplication] windows];
        for(topWindow in windows)
        {
            if (topWindow.windowLevel == UIWindowLevelNormal)
                break;
        }
    }

    UIView *rootView = [[topWindow subviews] objectAtIndex:0];  
    id nextResponder = [rootView nextResponder];

    if ([nextResponder isKindOfClass:[UIViewController class]])
        self.rootViewController = nextResponder;

    else
        NSAssert(NO, @"ShareKit: Could not find a root view controller.  You can assign one manually by calling [[SHK currentHelper] setRootViewController:YOURROOTVIEWCONTROLLER].");
}

// Find the top most view controller being displayed (so we can add the modal view to it and not one that is hidden)
UIViewController *topViewController = [self getTopViewController];  
if (topViewController == nil)
    NSAssert(NO, @"ShareKit: There is no view controller to display from");


// If a view is already being shown, hide it, and then try again
if (currentView != nil)
{
    self.pendingView = vc;
    [[currentView parentViewController] dismissModalViewControllerAnimated:YES];
    return;
}

// Wrap the view in a nav controller if not already
if (![vc respondsToSelector:@selector(pushViewController:animated:)])
{
    UINavigationController *nav = [[[UINavigationController alloc] initWithRootViewController:vc] autorelease];

    if ([nav respondsToSelector:@selector(modalPresentationStyle)])
        nav.modalPresentationStyle = [SHK modalPresentationStyle];

    if ([nav respondsToSelector:@selector(modalTransitionStyle)])
        nav.modalTransitionStyle = [SHK modalTransitionStyle];

    nav.navigationBar.barStyle = nav.toolbar.barStyle = [SHK barStyle];

    [topViewController presentModalViewController:nav animated:YES];            
    self.currentView = nav;
}

// Show the nav controller
else
{       
    if ([vc respondsToSelector:@selector(modalPresentationStyle)])
        vc.modalPresentationStyle = [SHK modalPresentationStyle];

    if ([vc respondsToSelector:@selector(modalTransitionStyle)])
        vc.modalTransitionStyle = [SHK modalTransitionStyle];

    [topViewController presentModalViewController:vc animated:YES];
    [(UINavigationController *)vc navigationBar].barStyle = 
    [(UINavigationController *)vc toolbar].barStyle = [SHK barStyle];
    self.currentView = vc;
}

self.pendingView = nil;

}

(void)hideCurrentViewController { [self hideCurrentViewControllerAnimated:YES]; }

This is a known error, which showed up on ios5. This has been fixed a long time ago in ShareKit 2.0. If you decide to upgrade, make sure to follow new install wiki very carefully and literally, since many things have changed comparing to the original sharekit .
