navc = [[UINavigationController alloc] init] ;/ / navc is a UINavigationController Object defined in. c

[Window addSubview: navc.view];

if (self.gameHallViewController == nil) {/ / gameHallViewController is a propertity defined in. c
GameHallViewController * gameHall = [[GameHallViewController alloc] initWithNibName: @ "GameHallViewController" bundle: nil];
/ / Tab_ChinaChessController * tabc = [[Tab_ChinaChessController alloc] initWithNibName: @ "Tab_ChinaChessController" bundle: nil];
self.gameHallViewController = gameHall;
[GameHall release];
}

Well, remove the annotations can be displayed, but the emergence of a strange phenomenon, I defined a button on page 1, and jump to the page after 2 also shows that at that very strange. Methods can not insert and push to complete the jump feature? Why am I here insert can jump, push pointing thank you but no response Hope
