当通过PUSH的时候，可以使用

favori.hidesBottomBarWhenPushed =YES;

否则：

- (void)hideTabBar {

if (self.tabBarController.tabBar.hidden == YES) {

return;

}

UIView *contentView;

    if ( [[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]] )

        contentView = [self.tabBarController.view.subviews objectAtIndex:1];

    else

        contentView = [self.tabBarController.view.subviews objectAtIndex:0];

contentView.frame = CGRectMake(contentView.bounds.origin.x, 

   contentView.bounds.origin.y, 

   contentView.bounds.size.width, 

   contentView.bounds.size.height + self.tabBarController.tabBar.frame.size.height);        

self.tabBarController.tabBar.hidden = YES;

}

- (void)showTabBar

{

if (self.tabBarController.tabBar.hidden == NO)

    {

return;

}

UIView *contentView;

    if ([[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]])

        contentView = [self.tabBarController.view.subviews objectAtIndex:1];

    else

        contentView = [self.tabBarController.view.subviews objectAtIndex:0];      

    

contentView.frame = CGRectMake(contentView.bounds.origin.x, 

   contentView.bounds.origin.y, 

   contentView.bounds.size.width, 

   contentView.bounds.size.height - self.tabBarController.tabBar.frame.size.height);

self.tabBarController.tabBar.hidden = NO;

}
