UIView Drawing Model

-[UIView setNeedsDisplay]

You have some kind of custom UIView which implements some awesome drawing in -[UIView drawRect:]. In order to have UIKit draw it for you, you send the -[UIView setNeedsDisplay] to the view object to queue it up for drawing.

-[CALayer setNeedsDisplay]

CGRectDivide is handy for slicing up a rectangle.

Example of getting a slice and the remaining area of a rectange.

CGRect rect = CGRectMake(0, 0, 240, 150);
  
CGRect remainder, slice;
    
CGRectDivide(rect, &slice, &remainder, 120, CGRectMinYEdge);

The NSKeyValueObserving addition to NSObject adds an observe message that takes an identifying context pointer – don't use NULL in its place.

Your superclass may observe the same key path for the same object. You need to pass along its observations, and only take actions on yours. The context pointer distinguishes which observations are yours.

static void *kContext = &kContext;

To conform to Apple's human-interface guidelines, you need to implement the following tasks when subclassing UIViewController and including a UITableView in your hierarchy (hence recreating UITableViewController):

Clear any selection in the table view before it's displayed

In -[UIViewController viewWillAppear:], clear the selected row (if any) by sending the -[UITableView deselectRowAtIndexPath:animated:] message.

Flash scroll view's scroll indicators

In -[UIViewController viewDidAppear:], send the -[UITableView flashScrollIndicators] message.
