iOS/xcode/objective-c : How to instantiate view controller after signup

Question

成功注册后，我希望用户完成提供照片等的过程。与下面类似的代码可以加载登录页面，但下面的代码无法在 Storyboard“newuser”中加载单独的 View Controller ”。

如有任何修复建议，我们将不胜感激。

- (void)presentNewUserInterface
{
    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"newuser"];
    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
    self.window.rootViewController = navigation;     
}

Answer 1

代替:

- (void)presentNewUserInterface
{
    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"newuser"];
    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
    self.window.rootViewController = navigation;     
}

尝试:

- (void)presentNewUserInterface
{
    UIViewController* rootController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"newuser"];
    UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
    [self presentViewController:navigation animated:YES completion:nil];    
}

您没有在示例中展示新的导航 Controller 。您尝试更换 rootViewController 是否有特殊原因？那不应该是必需的。我的示例应该足以显示您在用户注册过程中的下一个流程。
