目前，我正在尝试通过以下代码以编程方式触发“didSelectViewController”方法:
self.tabController.selectedViewController
= [self.tabController.viewControllers objectAtIndex:NEWSTAB_INDEX];
但是，没有调用'didSelectViewController'方法。如何触发该方法而无需手动选择选项卡栏？
最佳答案
self.tabController.selectedIndex = NEWSTAB_INDEX; // to actually switch to the controller (your code would work as well) - not sure if this does or not send the didSelectViewController: message to the delegate
[self.tabController.delegate tabBarController:self.tabController didSelectViewController:[self.tabController.viewControllers objectAtIndex:NEWSTAB_INDEX]]; // send didSelectViewController to the tabBarController delegate
