How could this be possible.Please anybody help me in achieving this tasks

The splash screen is just an image that should be called default.png. It will display during the launch of you app.

To realize what you want you have to define the first view controller with the same background and a UIProgress and do your sync and other processes.

When initialization is done you have to display your "real" first view controller

When user launch the application you could show a splash screen for 1 or 2 second after that you could show the progress (status) of your application using text msg.

for example "Initialization of Synchronization Service" ,"Storing to data base", "Loading map" .

The above text msg. is just a reference,you could have more descriptive text to show on screen along with progress bar.
