Which is the best way to display a view controller?

There are two ways to display a view controller onscreen: embed it in a container view controller or present it. Container view controllers provide an app’s primary navigation, but presenting view controllers is also an important navigation tool. You use direct presentation to display a new view controller on top of the current one.

What is the name of the video display controller?

The MC6847 is a video display generator (VDG) first introduced by Motorola and used in the TRS-80 Color Computer, Dragon 32/64, Laser 200 and Acorn Atom among others. The MOS Technology 6560 (NTSC) and 6561 (PAL) are known as the video interface controller (VIC) and used in the Commodore VIC-20.

When to use Direct presentation in view controller?

You use direct presentation to display a new view controller on top of the current one. Typically, you present view controllers when you want to implement modal interfaces, but you can also use them for other purposes. Support for presenting view controllers is built in to the UIViewController class and is available to all view controller objects.

How does a table view controller display search results?

It creates another custom table view controller to display the search results. This table view controller also acts as the presenter or provides context for the search results so they’re presented within their own context. This sample includes the optional—but recommended— UIStateRestoring protocol.
