I am trying to implement custom tab bar and custom side menu in one iOS application, like in the new Facebook iOS application. I tried with following links https://github.com/mikefrederick/MFSideMenu and https://github.com/isaacueca/3dglobe/tree/4648fed5915cef53c58f3e54efadf0f512446e59/xCode/UniversialGlobe/Classes with DDKCustomTabbar classes, however when I am trying to put them both using this code:
[self.window addSubview:sideMenu.view];
[self.window addSubview:tabbar.view];
tabbar overlays the sideMenu and opposite.
A few quick points,
Your trying to add them both to the window, which is almost certainly not what you want. Instead you want to set a single root view controller on the window.
Now looking quickly at those 2 projects, what you'll need to do is create a menu view controller with a tab bar view controller as the center view controller. Then set the menu view controller as the root view controller of the window. Here is a very rough example of how you might do this.
GTabBar *tabBarViewController = [[GTabBar alloc] initWithTabViewControllers:@[<Tab View Controller>] tabItems:@[<TabBarItems>] initialTab:0];
YourLeftSideBarMenuViewController *leftMenuViewController = [[YourLeftSideBarMenuViewController alloc] init];
YourRightSideBarMenuViewController *rightMenuViewController = [[YourRightSideBarMenuViewController alloc] init];
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:tabBarViewController
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
Have a look at the basic demo included in the menu MFSideMenu project.
I'd also suggest reading up a bit on how UIKit works, so you understand the difference between a window, view, viewController etc...
