Manoel,
Maybe you need to enable a specific capability. For instance, in audio, to have audio being played when the app is suspended you need to enable background audio. Sometimes, this capabilities are only possible being enabled by using xcode, therefore you need to use qmake to generate the xcode project.
Also, have you seen my last email? To know when the app is terminated or suspended you need to implement this calls on your app delegate:
- (void)applicationWillResignActive:(UIApplication *)application;
- (void)applicationDidEnterBackground:(UIApplication *)application;
-(void)applicationWillTerminate:(UIApplication *)application;
