在SWRevealViewController之前登录视图控制器

时间:2015-02-09 21:29:07

标签: ios objective-c uiviewcontroller parse-platform swrevealviewcontroller

如果注册或登录成功,我按照parse.com教程了解如何实现login + register + segue到主控制器。这很美。

然后我想使用SWRevealViewController实现侧面导航。我在此关注了APPCODA链接,并且仅在" SWRevealViewController"是初始视图控制器。

当我将我的解析登录控制器作为初始时,我无法从导航控制器中看到任何东西,即#SW; SWRevealViewController。"

如何解决这个问题,让我的登录/注册控制器成为初始控制器,并且在登录/注册成功时仍然能够拥有SWRevealViewController?

我将不胜感激任何帮助或指示。

下面是我的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;
    }

在具有用户会话的应用中,通常最好将登录/注册保持在与应用程序其余部分不同的视图层次结构中,并在存在活动会话时显示内部结构。您可以通过检查

来实现此目的
[PFUser currentUser]

因为如果用户没有登录,它将返回nil

在AppDelegate中提供支票,如下所示:

- (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,包括

- (void)showHomeScreen;

AppDelegate.h中,您可以在注册/登录成功后调用此方法:

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

我只是想知道如何以编程方式从app delegate显示我的仪表板视图。使用SWRevealViewController&amp; swift 2.0:

在你的main.storyboard上,你必须识别菜单视图(我的意思不是导航控制器)

我的右侧菜单,身份检查员 - &gt; identiy-&gt; storyboardID ='right2'。

我的左侧菜单,称为'rear2'。

对于我的前视图,在显示我的仪表板视图的导航视图控制器上,我将标识设置为“仪表板”

在你的appdelegate中,在我的函数'didFinishLaunchingWithOptions'下:

//this is your main.storyboard
let storyboard = UIStoryboard(name: "Main", bundle: nil)

//initialize your FRONT view controller, ie my dashboard view, mine   is a UINavigationController, which then presents a table view , ie why i instantiate with a UINavigationController.

let frontviewcontroller = storyboard.instantiateViewControllerWithIdentifier("dashboard") as? UINavigationController


//initialize REAR View Controller- it is the LEFT hand menu. 

let rearViewController = storyboard.instantiateViewControllerWithIdentifier("rear2") as? UITableViewController

//initialize RIGHT View Controller - it is your RIGHT hand menu.

let rightViewController = storyboard.instantiateViewControllerWithIdentifier("right2") as? UITableViewController

let mainRevealController = SWRevealViewController()

mainRevealController.frontViewController = frontviewcontroller
mainRevealController.rightViewController = rightViewController
mainRevealController.rearViewController = rearViewController

self.window!.rootViewController = mainRevealController
self.window?.makeKeyAndVisible()

希望它可以帮助别人。 谢谢 d。

以下是我在用户登录后换出导航层次结构的方式:

UINavigationController版本

+ (void)postSignInUICodeFromViewController:(UIViewController *)vc {
    // Log in was successful

    // Create new view controller
    ViewController1 *v1             = [[ViewController1 alloc] init];

    typeof(vc) weakVc               = vc;
    // This is a property that I have added to my
    // custom UIViewController subclass. As you might
    // guess, it's called in "viewDidAppear:"
    v1.viewDidAppearCompletionBlock = ^{
        // After pushing the new UI hierarchy into view,
        // this will delete/remove the rest of the UI stack
        weakVc.navigationController.viewControllers = @[v1];
    };
    // At this point (since the block above hasn't yet fired),
    // you're pushing your new UI hierarchy ON TOP OF the login
    // view controller
    [vc.navigationController pushViewController:v1 animated:YES];
}

UITabBarController版本

+ (void)postSignInUICodeFromViewController:(UIViewController *)vc {
    // Log in was successful

    // Create new UI hierarchy
    ViewController1 *v1             = [[ViewController1 alloc] init];
    NavViewController *nav1         = [[UINavController alloc] initWithRootViewController:v1];
    ViewController1 *v2             = [[ViewController2 alloc] init];
    NavViewController *nav2         = [[UINavController alloc] initWithRootViewController:v2];
    ViewController1 *v3             = [[ViewController3 alloc] init];
    NavViewController *nav3         = [[UINavController alloc] initWithRootViewController:v3];
    ViewController1 *v4             = [[ViewController4 alloc] init];
    NavViewController *nav4         = [[UINavController alloc] initWithRootViewController:v4];

    TabBarViewController *tabBar    = [[TabBarViewController alloc] init];
    tabBar.viewControllers          = @[nav1, nav2, nav3, nav4];

    typeof(vc) weakVc               = vc;
    typeof(tabBar) weakTabBar       = tabBar;
    __weak NavViewController *navVc = (NavViewController *)weakVc.navigationController;
    // This is a property that I have added to my
    // custom UITabBarController subclass. As you might
    // guess, it's called in "viewDidAppear:"
    tabBar.viewDidAppearCompletionBlock = ^{
        // After pushing the new UI hierarchy into view,
        // this will delete/remove the rest of the UI stack
        weakVc.navigationController.viewControllers = @[weakTabBar];
    };
    // At this point (since the block above hasn't yet fired),
    // you're pushing your new UI hierarchy ON TOP OF the login
    // view controller
    [vc.navigationController pushViewController:tabBar animated:YES];
}

在这两个例子中,我组成了一个名为ViewController1的新类。在UITabBarController示例中,所有其余内容也由类名组成,仅用于说明目的。 您需要输入您的班级名称。

好的,我明白了。在这里;

不是创建主视图控制器的segue,而是创建它到SWRevealViewController。我认为SW将该控制器设置为“sw_front”。只有通过PFUser将其作为segue才能使用。

登录ViewController 创建按钮操作。

你可以像这样设置。

  @IBAction func btnLoginAction(_ sender: UIButton) {

    let objAppDelegate = UIApplication.shared.delegate as! AppDelegate
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let rearViewController = storyboard.instantiateViewController(withIdentifier: "backTableVc") as? backTableVc
    let frontViewController = storyboard.instantiateViewController(withIdentifier: "ViewController") as? ViewController
    let naviRoot = UINavigationController(rootViewController: frontViewController!)
    naviRoot.navigationBar.isHidden = true
    let mainRevealController = SWRevealViewController()
    mainRevealController.frontViewController = naviRoot
    mainRevealController.rearViewController = rearViewController

    UIView.transition(from: (objAppDelegate.window?.rootViewController!.view)!, to: mainRevealController.view, duration: 0.6, options: [.transitionCrossDissolve], completion: {
        _ in
        objAppDelegate.window?.rootViewController = mainRevealController
    })
    objAppDelegate.window?.makeKeyAndVisible()

}
