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.

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.

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.

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.

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!
