Defined as a class method, easy to invoke.

The most important method is the overloaded push method

-(void) Pushviewcontroller: (Uiviewcontroller *) Viewcontroller animated: (BOOL) animated{if(self.viewcontrollers.count>0) {//If push comes in not a stack-bottom controller,viewcontroller.hidesbottombarwhenpushed =YES; ViewController.navigationItem.leftBarButtonItem= [Uibarbuttonitem itemwithimage:@"Navigationbar_back"Highimage:@"navigationbar_back_highlighted"target:self Action: @selector (back)]; ViewController.navigationItem.rightBarButtonItem= [Uibarbuttonitem itemwithimage:@"Navigationbar_more"Highimage:@"navigationbar_more_highlighted"target:self Action: @selector (more)]; } [Super Pushviewcontroller:viewcontroller animated:yes];}

Push to set the corresponding properties, including the corresponding background and highlight the background click Time corresponding to the response function.

Sets the response content of the corresponding button click.

-(void) more
{
[Self poptorootviewcontrolleranimated:yes];
}
-(void) back
{
[Self popviewcontrolleranimated:yes];
}
