用一個lynaviViewController繼承navigation，在app delegate中初始化lynaviViewController，然後self.window.rootViewController = lyNaviViewController; 要跳轉頁面時用lynaviViewController，程式碼片段：lyNaviViewController = [[LYNaviViewController alloc] init]; self.window.rootViewController = lyNaviViewController; [lyNaviViewController setNavigationBarHidden:true]; HLMainViewController* hlMain = [[HLMainViewController alloc] init]; [hlMain initContentViews];[lyNaviViewController pushViewController:hlMain animated:false];
