4. iCloud
• iCloud is certainly one of the most visible items being
added in iOS 5.
• iCloud allows apps to use cloud-based storage of
documents and key/value data. Changes are wirelessly
pushed to iCloud and automatically synced on all
devices.
• iCloud can also increase the possibilities of sharing
content. Any iCloud document can be given a public
URL, so apps can provide users with URLs that let them
share documents online, which also has the advantage of
providing some viral marketing possibilities for apps.

5. Notification Center
• All your alerts. All in one
place.
• We will get all kinds of
notifications on our iOS
device: new email, texts,
friend requests, and more.
• Notification Center provides
an innovative way to easily
display and manage your app
notifications without
interrupting your users.

• In iMessage, crate a new
messaging service for all ios 5
user.

message.

7. Newsstand
• iOS 5 organizes your magazine
and newspaper app
subscriptions in Newsstand.

8. Reminders
• A better way to do to-dos.
• Complete with due dates and
locations.
• Say you need to remember to
pick up milk during your next
grocery trip. Since Reminders
can be location based, you’ll get
an alert as soon as you pull into
the supermarket parking lot.

9. Twitter
• Integrated right into iOS 5.
• iOS 5 makes it even easier to tweet.
• Sign in once in Settings, and suddenly you
can tweet directly from Safari, Photos,
Camera, YouTube, or Maps.
• Want to mention or @reply to a friend?
Contacts applies your friends’ Twitter
usernames and profile pictures. So you can
start typing a name and iOS 5 does the rest.
• You can even add a location to any tweet,
no matter which app you’re tweeting from.

10. Camera
• Capture the moment at a
moment’s notice.
• You can open the Camera app
right from the Lock screen. Use
grid lines, pinch-to-zoom
gestures, and single-tap focus
and exposure locks to compose
a picture on the fly. Then press
the volume-up button to snap
your photo in the nick of time.

11. Photos
• Enhanced photo
enhancements.
• Turn your snapshots into
frame-worthy photos in
just a few taps. Crop,
rotate, enhance, and
remove red-eye without
leaving the Photos app.

12. Safari
• iOS 5 brings even more web-
browsing features to iPhone,
iPad, and iPod touch.

articles without ads or clutter so
you can read without
distractions.

17. Wi-Fi Sync
• Wirelessly sync your iOS device to your Mac
or PC over a shared Wi-Fi connection.
• Every time you connect your iOS device to a
power source, it automatically syncs and
backs up any new content to iTunes. So you
always have your movies, TV shows, home
videos, and photo albums everywhere you
want them.

18. Multitasking Gestures for iPad
• iOS 5 includes a few new moves and shortcuts to
help you get around even quicker on your iPad:
Using four or five fingers, swipe up to reveal the
multitasking bar, pinch to return to the Home screen,
and swipe left or right to switch between apps.

19. AirPlay Mirroring
• your audience in the board room, classroom,
or living room. AirPlay now supports video
mirroring. Which means you can wirelessly
— and securely — stream whatever’s on your
iPad 2 or iPhone 4S to your HDTV via Apple
TV. Everyone in the room sees exactly what’s
on your iPad or iPhone display up on the big
screen — even when you rotate your device
from portrait to landscape or zoom in and out.

20. User-Defined Keyboard Shortcuts
• Go to your Settings menu,
and navigate to
General>Keyboard. Scroll to
the bottom, and you’ll find a
prompt to add a new
shortcut. Just type in the
word or phrase that
deserves a shortcut, and
then plug in the shortcut
itself.

21. Create Custom Vibrations for Stealth Alerts
• By assigning a unique
vibration sequence to any
contact, you can leave
your iPhone on the table
and listen for the sweet
euphony of a customized
“zizip, zizip” as your device
resonates against the table
top.

22. Instant Definitions
• The Suggest function provides a list of other words you may have
preferred to type. Quote Level either increases or decreases the number
of vertical lines that appear before text — helpful when you’re annotating
a threaded conversation. But one of the niftiest options is Define, shown
here, which provides a tight (but surprisingly robust) dictionary entry for
the selection, complete with a definition, usage examples, and often
information on word derivatives and origin.

23. Check App Usage, Dispatch Offenders
• If you fear your iDevice is
approaching the limits of its
storage capacity, head on over to
Settings>General>Usage, and start
surveying your worst offenders.
Clicking on an app name will
provide a bit more detail —
specifically, the footprint of the
document and data files associated
with the app. You’ll also see a
button to delete the app entirely.

24. Alternate Routes in Maps
• Views of alternate routes have always been available in the
desktop version of Google Maps, and now they’re finally
available on iOS devices too. After defining where you are
and where you want to be, just tap Route 1, Route 2, etc., to
toggle between Google’s recommended directions.

25. New Features in Xcode 4.2
• Xcode 4.2 adds features to support iOS 5 as
well as other enhancements to the
application.

26. Automatic Reference Counting
• Automatic Reference Counting (ARC) for Objective-C
makes memory management the job of the compiler.
• By enabling ARC with the new Apple LLVM compiler,
you will never need to type retain or release again.
• dramatically simplifying the development process,
while reducing crashes and memory leaks.
• The compiler has a complete understanding of your
objects, and releases each object the instant it is no
longer used, so apps run as fast as ever, with
predictable, smooth performance.

27. Default Compiler
• The default compiler for iOS development in
Xcode 4.2 is LLVM 3.0. Compared with the
GCC compiler that was the default in Xcode
4.0 and the LLVM-GCC compiler in Xcode 4.1,
LLVM provides better code generation and
optimization than GCC, along with newer
language support than LLVM-GCC, including
support for ARC in Objective-C and for the
new C++ standard, C++0x.

28. Location Simulation
• In Xcode 4.0 and 4.1, you could
simulate only the current
location in your application.
• As of Xcode 4.2, you can
simulate locations other than
your current location in iOS
applications that use Core
Location.
• To set a location, choose Edit
Scheme from the scheme
selector in the toolbar, select the
Run action, and click the Options
tab. You can then choose a
location from the Location

29. Application Data Management
• In Xcode 4.2, you can save and restore
application data files on a simulator or iOS
device when debugging or running unit tests.
