标题: ios - 关闭后弹出 View Controller

我有一个导航 Controller A，我在其上推送 View Controller B。我从 B 模态地呈现 View Controller C。我需要同时关闭 C 和弹出 B。我想按顺序进行，首先保持关闭动画，然后是从 B 到 A 的弹出动画。我尝试了这段代码但没有成功:

[self dismissViewControllerAnimated:YES completion:^{
       [self.presentingViewController.navigationController popViewControllerAnimated:YES];
}];

关于如何实现这一点的任何建议？

Best Answer-推荐答案

如果您使用 C viewcontoller 编写，那么:

UIViewController *pvc = self.presentingViewController;
UINavigationController *navController = [pvc isKindOfClass:[UINavigationController class]] ? (UINavigationController *)pvc : pvc.navigationController;
[self dismissViewControllerAnimated:YES completion:^{
  [navController popViewControllerAnimated:YES];
}];

或者如果在B View Controller 中

[self.presentedViewController dismissViewControllerAnimated:YES completion:^{
   [self.navigationController popViewControllerAnimated:YES];
}];
