[BUG]when change to another view and back, the visible row is wrong

[kilik52]

To reproduce this, first add a TabbarController in RJAppDelegate.m

UIViewController *dummyVC = [[UIViewController alloc] init];
[dummyVC.view setBackgroundColor:[UIColor redColor]];

self.tabbarController = [[UITabBarController alloc] init];
self.tabbarController.viewControllers = @[self.navigationController,dummyVC];

self.window.rootViewController = self.tabbarController;

Run the code, scroll to the end. Switch to tab 2, and switch back.
You will see now the scroll position is not at the end of the tableview.

I'm almost certain that you're running into the same Apple bug that has been raised numerous times, most recently here: #8

Please file duplicate radars with Apple so that they prioritize a fix.
