从 AppDelegate 推送视图控制器 - RESideMenu class

Question

我正在使用 RESideMenu class 并在此 class 导航控制器的内容中使用，并在左侧菜单中使用一些视图。

该导航为内容主视图和详情视图。

我想在收到通知时从 app delegate 推送详细信息视图，所以我写了那个，但它不起作用。

NSString *URL = @"any url";


UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UINavigationController *mainNavigation = (UINavigationController *) [storyboard instantiateViewControllerWithIdentifier:@"MainNavigation"];



MainViewController *mainVC = (MainViewController *) [storyboard instantiateViewControllerWithIdentifier:@"MainViewController"];
DetailViewController *detailVC = (DetailViewController *) [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];

[mainNavigation setViewControllers:@[mainVC, detailVC]];
[mainNavigation popViewControllerAnimated:YES];

[detailVC setNewsLink:URL];
[mainNavigation pushViewController:detailVC animated:YES];

有人可以帮忙吗？

--------------------** 更新

RESideMenu *sideMenu = (RESideMenu *) [storyboard instantiateViewControllerWithIdentifier:@"RootViewController"];
UINavigationController *mainNavigation = (UINavigationController *) [sideMenu contentViewController];

[mainNavigation pushViewController:detailVC animated:YES];

Answer 1

您没有使用 "current navigation controller" 并推送到详细信息。您正在实例化 new mainNavigation（不是当前的）并推送到详细信息。您需要获取 current mainNavigation（例如，在启动时存储在属性中）然后推送到新的 DetailViewController.

更新

在这种情况下，您使用的是 RESideMenu。您必须获取 contentViewController（可能是 UINavigatorController）并从中推送。

例子

DetailViewController *detailVC = (DetailViewController *) [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];

NSString *URL = @"any url";
[detailVC setNewsLink:URL];

[((UINavigationController *)self.sideMenuViewController.contentViewController) pushViewController:detailVC animated:YES];

可能，在您的 AppDelegate 中，RESideMenu 就是您的 self.window.rootViewController。那么：

DetailViewController *detailVC = (DetailViewController *) [storyboard instantiateViewControllerWithIdentifier:@"DetailViewController"];

NSString *URL = @"any url";
[detailVC setNewsLink:URL];

RESideMenu *sideMenu = (RESideMenu *)self.window.rootViewController;
[((UINavigationController *)sideMenu.contentViewController) pushViewController:detailVC animated:YES];
