问题
I'm new to swift and iOS programming. Recently, I was exploring Drawer options and tried MMDrawer tutorial as explained in this link. I followed it step by step and it works great in a single view. ie, app loads to central view and I can swipe right / left to access drawer controllers.
Now, I want to add a tab bar controller before my current view, ie, hierarchy is
tab view controller [tab 1]---> Nav Controller --> drawer central view (swipe action takes place in here)
[tab 2]---> Nav Controller --> Different controller view
But due to code in appDelegate (central view, left nav and right nav instantiation), I directly land to my central view and tab bar doesn't appear in that case. I believe that instead of instantiating all of the code in appDelegate, I have to instantiate it in one of the sub view class. But I couldn't find any resources online.
