SWRevealViewController之前的Login View控制器 [英] Login View controller before SWRevealViewController

问题描述

我遵循parse.com教程，以了解如果注册或登录成功，则如何实现登录+注册+对主控制器进行segue.这很漂亮.

I followed parse.com tutorials on how to implement login + register + segue to main controller if registration or login is successful. This works beautiful.

然后，我想使用SWRevealViewController实现侧面导航.我遵循了APPCODA链接，并且只有在"SWRevealViewController"是初始视图控制器时，它才起作用.

I then wanted to implement a side navigation using SWRevealViewController. I followed APPCODA link on this and got it working only when "SWRevealViewController" is the initial view controller.

当我将解析登录控制器作为初始名称时，我从导航控制器(即"SWRevealViewController")中看不到任何东西.

When i have my parse login controller as initial i can't see anything from the navigational controller aka "SWRevealViewController."

当登录/注册成功后，我将如何解决此问题，将我的登录/注册控制器设置为初始控制器，并且仍然能够拥有SWRevealViewController?

how would i be able fix this, make my login/register controllers the initial controllers and still be able to have SWRevealViewController when login/register is successful?

我将不胜感激任何帮助或指示.

i would appreciate any help or pointers.

下面是我的APPDelegate.m

below is my APPDelegate.m

#import "AppDelegate.h"
#import <Parse/Parse.h>
#import <GoogleMaps/GoogleMaps.h>

@interface AppDelegate ()

@end

@implementation AppDelegate



- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

LoginView *lv = [[LoginView alloc]init];

SidebarViewController *sbvc = [[SidebarViewController alloc]init];
UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:lv];
UINavigationController *menuVC = [[UINavigationController alloc]initWithRootViewController:sbvc];

SWRevealViewController *revealController = [[SWRevealViewController alloc]initWithRearViewController:menuVC frontViewController:nav];
revealController.delegate = self;

self.menu = revealController;
self.window.rootViewController = self.menu;


[GMSServices provideAPIKey:@"XXXXXXXXXX"];

[Parse setApplicationId:@"XXXXXXXXXXXXX"
              clientKey:@"XXXXXXXXXXXXX"];

[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];



  return YES;
    }

推荐答案

在具有用户会话的应用中，通常最好将登录/注册与应用的其余部分保持在单独的视图层次结构中，并在其中显示内部结构是一个活跃的会话.您可以通过检查

In apps with user sessions, it is usually best to keep login/signup on a separate view hierarchy from the rest of the app and present the internal structure if there is an active session. You can achieve this by checking for

[PFUser currentUser]

，因为如果用户未登录，它将返回nil.

as it will return nil if the user is not logged in.

像这样在您的AppDelegate中提供支票:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // .. Rest of your initialization code

    if ([PFUser currentUser]) {

        // Let's pop them right to the home screen
        [self showHomeScreen];
    }
    else {

        // Present login vc
        LoginView *lv = [[LoginView alloc] init];
        UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:lv];
        self.window.rootViewController = nav;
    }
    return YES;
}

- (void)showHomeScreen {

    SidebarViewController *sbvc = [[SidebarViewController alloc] init];
    UINavigationController *menuVC = [[UINavigationController alloc] initWithRootViewController:sbvc];

    UIViewController *home = [[UIViewController alloc] init];
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:home];

    SWRevealViewController *revealController = [[SWRevealViewController alloc] initWithRearViewController:menuVC frontViewController:nav];

    self.window.rootViewController = revealController;
}

然后，通过添加

- (void)showHomeScreen;

在AppDelegate.h中，您可以在成功注册/登录后调用此方法:

in AppDelegate.h, you can call this method upon successful registration/login:

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[delegate showHomeScreen];
