CPSchedulePowerUpAtDate on iOS iPhone SDK 4.0?

what's the equivalent of CPSchedulePowerUpAtDate on the iOS 4.0?

In iPhone OS 3.1.3 I could use it.

I'm getting this error:

dyld: lazy symbol binding failed: Symbol not found: _CP开发者_如何转开发SchedulePowerUpAtDate Referenced from: /Applications/AppABC.app/AppABC Expected in: /System/Library/PrivateFrameworks/AppSupport.framework/AppSupport

dyld: Symbol not found: _CPSchedulePowerUpAtDate Referenced from: /Applications/AppABC.app/AppABC Expected in: /System/Library/PrivateFrameworks/AppSupport.framework/AppSupport

(yes, it's a private framework, but I'm not programming for the appstore.)

Thanks!
