UIWindow How to implement a root controller jump without using a proxy (Implementation of page jumps)

1. Separate Jump page page

#pragma mark-changeviewcontroller Controller Jump

-(void) changeviewcontroller{

loginpagecontroller * login = [[loginpagecontrolleralloc]Init ];

uiwindow * window = [uiapplicationsharedapplication]. Keywindow;

Window. Rootviewcontroller = login;

}

@end

2. The jump page has navigation bar (Uinavigationcontroller) and Uitabbarcontroller

#pragma mark-viewcontroller Jump

-(void) changeviewcontroller{

detailpagecontroller * detailpage = [[detailpagecontrolleralloc] Init];

Uinavigationcontroller * NV = [[uinavigationcontrolleralloc] Initwithrootviewcontroller:d etailpage];

uitabbarcontroller * tab = [[uitabbarcontrolleralloc]Init ];

tab. Viewcontrollers =@[NV];//Add the navigation bar to the Tabbar controller

uiwindow * window = [uiapplicationsharedapplication]. Keywindow;

Window. Rootviewcontroller = tab;

}
