IOS tab Jump __ios

Today in IOS development process encountered a problem, is in the tab page jump.

What I want to achieve is to jump to the root View of tab3 from the TAB1,TAB2,TAB3,TAB4 page.

The following are the relevant code for implementation:

-(void) gotocartbtnpressed: (ID) sender

{

Self.tabBarController.tabBar.hidden =no;//because I need to jump that page to hide the tab Bar

[self.tabbarcontrollersetselectedviewcontroller:[self.tabbarcontroller.viewcontrollersobjectatindex:2]];// TAB Select Shopping Cart interface

[self.navigationcontrollerpoptorootviewcontrolleranimated:yes];//back to the root directory

}

The above is the implementation of the tab jump related code.
