iOS UINavigationBar vs UIToolbar vs UITabBar

Question

Let me know which one should be used in what case.

What are differences among them?

What are the advantage and disadvantage of each component?

Answer 1

The UINavigationBar class implements a control for navigating hierarchical content. It’s a bar, typically displayed at the top of the screen, containing buttons for navigating up and down a hierarchy. The primary properties are a left (back) button, a center title, and an optional right button.

An instance of the UIToolbar class is a control for selecting one of many buttons, called toolbar items. A toolbar momentarily highlights or does not change the appearance of an item when tapped. Use the UITabBar class if you need a radio button style control.

The UITabBar class implements a control for selecting one of two or more buttons, called items. The most common use of a tab bar is to implement a modal interface where tapping an item changes the selection.
