For custom views, just send your view the message to refresh itself.

For Objective-C

[yourView setNeedsDisplay];

or

[yourView setNeedsDisplayInRect:aRect];

For Swift

yourView.setNeedsDisplay()

or

yourView.setNeedDisplay(aRect)

The standard views generally refresh automatically whenever you change their contents, i.e. change the text of a label or the image of an imageview.
