I have problem. I need solve this problem for jailbreak iOS. My application works in background mode. I want that application go to foreground mode from background after some events. I tried next instruction:
system([[NSString stringWithFormat:@"uiopen \"%@\"", @"appname://"] UTF8String])
But application didn't run from background. App run as new process. Thank you.
User private API:
int SBSLaunchApplicationWithIdentifier(CFStringRef displayIdentifier, Boolean suspended);
It's defined in SpringboardServices private framework.
You will need to add entitlement "com.apple.springboard.launchapplications" for this to work.
