I[Pad] hate you so much right now
Lots of people got confused by this new product because it doesn’t fall into an existing category. No, it’s not
suppose to replace your iPhone or your Macbook. As Jobs said, it’s smack in the middle.
For me, it will be a companion for my Macbook during travel or a replacement for my iPhone for casual reading.
And my daughter will love playing Angelina Ballerina on it.
But not everyone notices that a whole ecosystem is changing – lots of businesses must be sad now.
Microsoft must be wetting their pants – their HP slate with Vista 7 is still light-years away.
Amazon is going to lose big time – they can’t justify the $500 Kindle DX anymore – it’s a device that can only
be used for reading books – or ridiculous fees. They had their opportunity to capture the ebooks market, in the
same way the iPod captured the online music market, but they wasted it. Think of it for a second – if they have sold
the initial Kindle really cheap (say, $100) they would have make lots of money on books. Unfortunately, it’s too late
for them now. Is it a surprise that they announced, 6 days before the Apple event, the Kindle Development Kit that
will allow developer to build “active content”?
There are lots of other “content publishers” which will be affected by this…
The iPad will change forever the way we interact with electronic resources and there is no way back.
Funny… it might even save some newspapers!

14. So what is it?

15. Good news
You already have over 1,000,000 customers

16. 2 paths
• universal app
• separate apps

17. Universal app

18. Universal app

19. Universal app

20. UIDevice.h
typedef enum {
#if __IPHONE_3_2 <= __IPHONE_OS_VERSION_MAX_ALLOWED
UIUserInterfaceIdiomPhone, // iPhone and iPod touch style UI
UIUserInterfaceIdiomPad, // iPad style UI
#endif
} UIUserInterfaceIdiom;
#define UI_USER_INTERFACE_IDIOM() ([[UIDevice currentDevice]
respondsToSelector:@selector(userInterfaceIdiom)] ? [[UIDevice currentDevice]
userInterfaceIdiom] : UIUserInterfaceIdiomPhone)
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
...
}

21. Separate app
The separate app will
have its own audience

22. Icon

25. Naming the app

26. Naming the app

27. There is no spoon

28. MVC

29. Split View
MyFirstViewController* firstVC = [[[MyFirstViewController alloc]
initWithNibName:@"FirstNib" bundle:nil] autorelease];
MySecondViewController* secondVC = [[[MySecondViewController alloc]
initWithNibName:@"SecondNib" bundle:nil] autorelease];
UISplitViewController* splitVC = [[UISplitViewController alloc] init];
splitVC.viewControllers = [NSArray arrayWithObjects:firstVC, secondVC, nil];
[self.view addSubview:splitVC.view];

30. Popovers

31. Popovers
MyCustomViewController* content = [[MyCustomViewController alloc] init];
UIPopoverController* aPopover = [[UIPopoverController alloc]
initWithContentViewController:content];
aPopover.delegate = self;
[content release];
self.popoverController = aPopover;
[aPopover release];
[self.popoverController presentPopoverFromBarButtonItem:sender
permittedArrowDirections:UIPopoverArrowDirectionAny
animated:YES];

32. Gesture Recognisers
Abstract class: typedef enum {
UIGestureRecognizer UITouchPhaseBegan,
UITouchPhaseMoved,
Concrete classes: UITouchPhaseStationary,
UITouchPhaseEnded,
UITapGestureRecognizer
UITouchPhaseCancelled,
UIPinchGestureRecognizer
} UITouchPhase;
UIPanGestureRecognize
UISwipeGestureRecognizer
UIRotationGestureRecognizer
UILongPressGestureRecognizer typedef enum {
UIGestureRecognizerStatePossible,
UIGestureRecognizerStateBegan,
UIGestureRecognizerStateChanged,
UIGestureRecognizerStateEnded,
UIGestureRecognizerStateCancelled,
UIGestureRecognizerStateFailed,
UIGestureRecognizerStateRecognized =
UIGestureRecognizerStateEnded
} UIGestureRecognizerState;

33. Document sharing
UIDocumentInteractionController* docController =
[UIDocumentInteractionController interactionControllerWithURL:fileURL];
docController.delegate = self;
Info.plist
CFBundleTypeName
CFBundleTypeIconFiles
LSItemContentTypes
LSHandlerRank

34. PDF graphic context
UIGraphicsBeginPDFContextToFile UIGraphicsBeginPDFContextToData
UIGraphicsBeginPDFPage UIGraphicsBeginPDFPageWithInfo
UIGraphicsBeginPDFPage
UIGraphicsEndPDFContext

35. Custom input view
UIResponder
@property (readonly, retain) UIView *inputView __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_2);
@property (readonly, retain) UIView *inputAccessoryView __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_2);
UITextView & UITextField

36. What else...
test, test, [Unit]Test
analytics - Flurry
test on device
4.0 is coming...
