The process of iPhone app development has to produce an app that has icon as well as a launch image. It is very important for iPhone applications to provide icon for iOS to make sure that this icon can be demonstrated in the Spotlight results as well as in results if needed. The app-specific document types can also be exhibited by the custom icons of the applications. Not only this but furthermore these custom icons make it possible to represent content, characteristics and modes in navigation bars, tool bars plus tab bars.

Unlike various other custom artwork in the application during iPhone apps development, these icons as well as images have to comply to selected standards so iOS can display them properly. Additionally, icon plus image files have naming requirements. Ahead of submitting the application bundle to the Application Store, there are particular things that iPhone developers are expected to offer in app bundle.

The app must have an Info.plist file which comprises info which the system needs to share data with the app. Even if the edition of this particular file is automatically designed by Xcode, that needed to be modified by the majority of the applications in a single manner or perhaps the some other. The critical data similar to configuration of the app is included in the Info.plist file therefore it is recommended to include this file in the app bundle. Each and every fresh project iPhone developers produce in Xcode offers a default Info.plist file configured with a few elementary data about the project.

The application's Info.plist file need to at all times include certain keys like UIRequiredDeviceCapabilities, CFBundleIcons, UISupportedInterfaceOrientations and so on. The capabilities of the application can be identified by a key referred to as UIRequiredDeviceCapabilities. The iPhone app developers can make even more usage of this specific key in order to help the app to stop supporting the ineffective attributes.

The favorite key to specify the icon files of the app is CFBundleIcons. CFBundleIconFiles key could possibly be instead involved by the additional tasks as well. Although both the keys essentially fulfill the similar function, CFBundleIcons is favored key since it enables the developers to manage their icons more effectively.

UISupportedInterfaceOrientations key that is included in Xcode is put to use by the developers to choose the collection of values at the beginning. But later on it really is recommended to keep on changing these values based on the orientations basically reinforced by the app.

The developers might wish to increase other keys in the Info.plist file based on the behavior of the app. A developer ought to involve UIBackgroundModes key in case the application allows performing in the background making use of one of the specified modes. For displaying the contents of sandbox's Documents directory in iTunes, the developers should make use of the UIFileSharingEnabled key.

UIRequiresPersistentWiFi is the key that have to be put to use when the application needs a Wi-Fi connection. UINewsstandApp key ought to be included in case the content in the application is used from Newsstand app.

There are two ways to change the property list Info.plist file- through the use of Xcode or personally. Each different Xcode project possesses a file referred to as <project_name>-Info.plist in which <project_name> is the name of developer's Xcode task. This particular file is actually the template that is utilized by Xcode for creating the Info.plist file at the time of creating the app. Upon the selection of this particular file, Xcode exhibits the property list editor which developers can utilize to incorporate or even remove keys and also alter the value of a key.

UIRequiredDeviceCapabilities key must be integrated in Info.plist file during the course of the iPhone app development. It is using this key which the App Store decides whether a customer is able to operate the app on a certain unit. When displaying the app, the app should consist of one or more icons to utilize. The icon is what is shown to the consumer on the iOS device's home screen.

There ought to be a minimum of one image in order to exhibit in the iPhone application whenever the application gets launched. The system shows the application's introduction picture just after launch in order to present the customer together with quick responses.
