ios - 弹出 View Controller 到通用 View Controller

Question

我有一个类似仪表板的应用程序，有时我想回到“仪表板” View Controller 。我无法更改 Root View Controller 。我完成这项任务的方式是通过一个静态实例。我使用这段代码:

static DashboardViewController *instance;
+ (instancetype) instance {
  return instance;
}

此实例在 viewDidLoad 中设置为 self。

所以当我想弹出这个 Controller 时，我使用:

  [self.navigationController popToViewController:[DashboardViewController instance] animated:YES];

我想知道这是要走的路还是应该有所不同？

Answer 1

试试这个，

for (UIViewController  *viewController in [self.navigationController viewControllers]) {

    //you can also use NSClassFromString(@"DashboardViewController") instead of [DashboardViewController class]
    if ([viewController isKindOfClass:[DashboardViewController class]]) {
        [self.navigationController popToViewController:viewController animated:YES];
    }
}
