Set the root controller to tabbar when the program starts, as shown below:
-(BOOL) application :( UIApplication *) application didfinishlaunchingwitexceptions :( NSDictionary *) launchOptions
{
Self. window = [[uiappswalloc] initWithFrame: [UIScreenmainScreen] bounds];

[SelfinitTabBar];
Self. window. rootViewController = self. tabBar;
Self. window. backgroundColor = [UIColorwhiteColor];
[Self. windowmakeKeyAndVisible];
Return YES;
