Many people view the creation of an iPhone application (or an app, as it is more commonly known) as the perfect way to strike it rich in an era that is more than a little focused online. The creation of these apps, however, is not all that cut and dry, as there are a number of restrictions placed on the iPhone application developers who are responsible for coding and programming. You should consider each of the following restrictions before making a commitment to creating your own app. 

  • One application at a time
    Unfortunately, Apple has decided that a user can only have one app running at a time. This means that if you are using a maps app that helps to direct you where you need to go, you will have to quit the program when you receive a phone call. This can become extremely annoying for users who have to quit every single time they receive a phone call or a message, especially if they have to input a username and password every single time they return.
  • No third parties in the background
    This restriction actually links with the one outlined above. It means that the program will not be able to collect messages for you whilst you are on a phone call or reading a text message. If browsing Facebook, for example, the app will immediately show you as offline when you take a phone call or switch apps. The same thing will happen with apps that require constant internet access for smooth operation; their connection will be interrupted when you leave.
  • Control on applications
    The Apple store is set up as a way for iPhone apps to be distributed and marketed to the masses. There is no other way for you to make your apps available. Apple also requires iPhone application developers to register with them before you are allowed to upload your apps, and there is still the possibility that they may reject your programs or delay their release for one reason or another. Not only is this trying for a developer, it can cause all sorts of other issues.
  • Revoking the certificate
    Even once Apple has accepted you as a developer, they are still able to exert complete control over you through their ability to simply revoke the certificate that they have given you. Whilst this may not seem like a problem, you must understand that Apple requires all legitimate apps to be signed and if that certificate is on the 'revocation list' then the app will not run. This can prove highly annoying to customers who have paid for the use of your application. 

As you could probably surmise, each of the above restrictions can really put iPhone application developers between a rock and a hard place. Not only do they have to contend with the overlords at Apple who want nothing more than to block them from distributing their apps, they have to contend with the fact that their programs will be constantly interrupted by phone calls. On top of this, Apple doesn't offer any support for apps that have been created for previous versions, nor will new apps work on these older phones.
