objective c - Present UIViewController above TabBar

Question

I am using a TabBarController, and from one of the tabs, I want to present another UIViewController, while keeping the TabBar displayed.

If I simply present or push the view controller, it is displayed in full screen, above the TabBar.

What is the right way to solve this issue?

Answer 1

Assume ViewControllerA is a UIViewController of TabBarController. And the UIViewController you want to present is ViewControllerB

To push ViewControllerB, while keeping the TabBar displayed. Simply inside ViewControllerA you just need to call

ViewControllerB *vc = // Initialize ViewControllerB here
[self.navigationController pushViewController:vc animated:YES];

To present ViewControllerB

ViewControllerB *vc = Initialize ViewControllerB here
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:vc animated:YES completion:nil];

With presenting, make sure you set UIModalPresentationOverCurrentContext for modalPresentationStyle property of ViewControllerB. If not, it will present fullscreen, over the TabBar

For easier understanding, i created a demo repo, you can take a look.
