iOS navigation controller Uinavigationcontroller, controller a jumps (push) to B, B jumps (push) to C, but C back (pop) enters a. The code in the B jump (push) to C is written as follows:

     Uinavigationcontroller *navcontroller = [[Self.navigationcontroller retain] autorelease];     [Navcontroller Popviewcontrolleranimated:no];     Viewcontrollerc *_viewcontroller = [[[[Viewcontrollerc alloc] init] autorelease];     [Navcontroller Pushviewcontroller:_viewcontroller Animated:yes];

Code parsing

    Self.navigationcontroller (..., Viewcontrollera, Viewcontrollerb)    //Navcontroller (nil)    Uinavigationcontroller *navcontroller = [[Self.navigationcontroller retain] autorelease];    Self.navigationcontroller (..., Viewcontrollera, Viewcontrollerb)    //Navcontroller (..., Viewcontrollera, Viewcontrollerb)    [Navcontroller Popviewcontrolleranimated:no];    Self.navigationcontroller (nil)    //Navcontroller (..., viewcontrollera)    Viewcontrollerc * _viewcontroller = [[[Viewcontrollerc alloc] init] autorelease];    _viewcontroller.messageentity = [Self.listarray objectAtIndex:indexPath.row];        Self.navigationcontroller (nil)    //Navcontroller (..., Viewcontrollera)    [Navcontroller Pushviewcontroller:_viewcontroller Animated:yes];    Self.navigationcontroller (nil)    //Navcontroller (..., Viewcontrollera, VIEWCONTROLLERC)
