Is there a way to accomplish what I want? Can I programmatically trigger the tab switch differently perhaps so that the shouldSelectViewController function gets called?
推荐答案
如果你已经实现了 - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController 在您的tabBarController委托中,比您可以手动调用。
If you have implemented - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController in your tabBarController's delegate than you can call it manually.
[self.tabBarController.delegate tabBarController:self.tabBarController shouldSelectViewController:[[tabBar viewControllers] objectAtIndex:2]]; [self.tabBarController setSelectedIndex:2];希望这有帮助。
