2. With so many criteria to bear in mind, iPhone application development
can really be a tricky business. It's a wonder how developers
incorporate so much into the code and create a flawlessly working
wonderful app. Well, to begin with , the screen size is small, there are
two different orientations to consider, there is the “touch” element
(which was absent in the traditional pc applications), plus to
accomodate some features you need to “show” or “hide” certain
features. Instead of giving you some abstract pointers, let's discuss in
detial four basic criteria to be considered while you develop an
application for iPhone.

3. Don't Forget That The Screen size and resolutions vary
too....
iPhones (prior to iPhone 4) have a screen size of 320 by 480
pixels. Apple's new screen revolution began with iPhone 4. With
an aim to optimize viewing experience, Apple introduced retina
displays with a greater screen resolution (640 x 960). The
physical screen size still remained the same. With the advent of
iPhone 5, the screen height has increased too!
For screen resolution changes don't forget to tweak your images –
for eg. Design them at a double soze, so that they look sharper
when displayed on retina screens. Well, as for physical size
changes, you can include additional style sheets to accomodate
them.

4. Don't Forget That There Are Two Orientations....
iPhone's ability to swap between two different orientations poses
another challenge for iPhone application development
professionals. Your applications will be viewed either in the
portrait view or in the landscape view. Most applications default
to the portrait view, but with countless users using your
applications, you need to accomodate for both the modes. To
cater to this requirement, use java scripts and include 180 – for
someone who might completely flip the phone! (very rarely
used), 90 and -90 to accomodate clockwise and anti-clockwise
rotation, 0 – for default portrait orientation.

5. Don't Forget About The Hidden Toolbars....
To optimize space, unnecessary elements can be hidden in your
application. Like while using the application, toolbars simply
occupy space. So, unless there are some unavoidable tools to
be used from the toolbar, most developers prefer hiding toolbar
when application is in use. It'll be beneficial, as space is scanty
too! You can add scripts to change the behavior of the
application to show or hide the toolbar.

6. Don't Forget About The Touch Element...
This is an obvious one. Iphones are touch screen devices. Iphone
application development must incorporate the different elements
such as opening with a simple touch, or tapping twice or moving
your fingers to zoom in and zoom out. Well, be innovative for
your own application!
