I got iPhone app.
When i start it, i see black view. This black view is shown before app's first view. And it looks really awful.
Can i set here preview picture?
yes you can. add a images with "Default.png" & "Default@2x.png" - "D" capital in your resources. add them to your project as well.
dimensions will be for:
Default.png = 320x480
Default@2x.png = 640x960
it will be used as splashscreen image which is lacking in your project.
