iPhone 4 only app

[mdansevern]

Hi folks,
I have finished development of my first iPhone app (which I started a couple of weeks ago). My app uses some OS4 only APIs, can I still deploy this app to the App Store even though it only works for iPhone 4 and uses new OS?

Also, of course it does not run on the iPad because of the OS version differences.

thank you.

Definitely. Why not?

Just your base SDK and deploy SDK properties should be set to iOS4.

But you can also make your code work on older OSs but adding code like

if ([object respondsToSelector:....) {
----iOS4 specific code here
} else {
----Code that runs on older devices instead
}

That way you aren't closing your market down with just iOS4 users.

Add this to you .plist:

Key: "Required device capabilities"

Value: "camera-flash"

What this will do is limit your app to only work with iPhone 4.

Thank you for the help.

I changed the Base SDK to 3.2, and now Im seeing this error:

The 'rootViewController' outlet of UIWindow is not available on releases prior to iPhone OS 4.0. Remove the connection and instead programmatically add the view controller's view to the window after the application finishes launching.


Anyone seen this before?

Errm... iOS 3.2 is for iPad...

Does your app specifically make use of the iPhone 4's hardware? If not, then you should just make your app iOS4 only instead of limiting sales to a single device.
