How to launch an APP in background in iOS 6.x silently

Question

We want to launch an APP silently in iPhone without bring this APP to the Foreground. In iOS 5.x we achieve this goal by this code:

    [(SBApplication*)app setDisplaySetting:0x4 flag:NO];
    [(SBDisplayStack*)displayStack pushDisplay:app];
    [(SBDisplayStack*)displayStack popDisplay:app];

But, in iOS 6.x there is not SBDisplayStack any more. I did some search but not found any answers. Someone says that SBWorkSpace replaces the SBDisplayStack in iOS 6.x. We use SBAppToAppWorkspaceTransaction to implement but always bring the APP to the Foreground which dose not achieve our goal.

Anyone can help me? Thx!

You can use the SBSLaunchApplicationWithIdentifier() function from the SpringBoardServices private framework. It takes a suspended argument:

SBSLaunchApplicationWithIdentifier(CFSTR("com.company.app"), TRUE);

You'll also need the com.apple.springboard.launchapplications entitlement for this.
