在iPhone和iPad上,JTRevealSideBar UI不会在横向模式下正常显示

在我的项目中，我正在使用JTRevealSideBar来显示侧面用户界面，但是当我将iPad / iPhone从纵向模式更改为横向模式时，用户界面会受到干扰

- (CGRect)applicationViewFrame {
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
CGRect expectedFrame = [self.view convertRect:appFrame fromView:nil];
return expectedFrame;

}

- (UIView *)viewForLeftSidebar {
CGRect mainFrame = [self.navigationController applicationViewFrame];
if (!self.leftSidebarViewController) {
    SP2SideBarViewController * sideController = [[SP2SideBarViewController alloc] initWithStyle:UITableViewStylePlain];
    self.leftSidebarViewController = sideController;
    [sideController release];
    self.leftSidebarViewController.sidebarDelegate = self;

    if ( self.callerAppName )
        [self.leftSidebarViewController setLaunchAppName:self.callerAppName];

    if ([UIHelper isPad]) {
        self.leftSidebarViewController.view.frame = CGRectMake(0,mainFrame.origin.y,SIDEBAR_IPAD_WIDTH,mainFrame.size.height);

    } else {
        self.leftSidebarViewController.view.frame = CGRectMake(0,170,mainFrame.size.height);
    }

    self.leftSidebarViewController.title = @"LeftSidebarViewController";
    self.leftSidebarViewController.view.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleHeight;
}

self.leftSidebarViewController.slideDecksCount = [slideDecks count];
self.leftSidebarViewController.jsonDecksCount = [self.jsonDecks count];
// [self.leftSidebarViewController.tableView reloadData];
return self.leftSidebarViewController.view;
}
