Iphone 从一个导航控制器切换到另一个导航视图控制器

我正在开发一个应用程序，其中使用两个导航控制器和uilocalNotification

第一个导航ViewController N1有两个ViewController v1和v2 第二个导航ViewController N2有两个ViewController v3和v4

另外，当应用程序处于后台时，如果出现UILocalNotification并且我单击它，应用程序应该检测显示的是哪个导航控制器和哪个viewController，然后切换到另一个navigationController的viewController

例如： 如果显示N1中的v2，则 单击通知后， 然后显示N2中切换到v3

如何做？？？

只需将下面的方法粘贴到

AppDelegate.m

文件中，并在需要更改

UINavigationController

时调用特定的方法即可

例如：如果您处于

N1

的

v2

中，并且通知已更改，则调用类似于bellow的bellow方法

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate setRootViewControllerN2];

使用以下方法切换带有动画的导航控制器

1。setRootViewControllerN1：这是用于设置带有N1 navigationController的RootViewController

-(void)setRootViewControllerN1{
    self.window.rootViewController = N1;

    [self.window makeKeyAndVisible];
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.window layer] addAnimation:animation forKey:kAnimationKey];
}

-(void)setRootViewControllerN2{
    self.window.rootViewController = N2;

    [self.window makeKeyAndVisible];
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.window layer] addAnimation:animation forKey:kAnimationKey];
}

2。setRootViewControllerN2：这是用于使用N2 navigationController设置RootViewController

-(void)setRootViewControllerN1{
    self.window.rootViewController = N1;

    [self.window makeKeyAndVisible];
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.window layer] addAnimation:animation forKey:kAnimationKey];
}

-(void)setRootViewControllerN2{
    self.window.rootViewController = N2;

    [self.window makeKeyAndVisible];
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.window layer] addAnimation:animation forKey:kAnimationKey];
}

不！实际上，当单击通知时，如何确定当前显示的是哪个viewcontroller和哪个navigationController…？？只需在AppDelegate或UserDEfault中创建一个BOOL变量，保存这一个值并将其从true切换为flase即可。。当在那个时候发生通知时，检查是否为true，然后只调用第二个方法并将该变量设置为false，否则调用第一个方法并将该变量设置为true…我很早就想到了standardUserDefaults，但后来我认为会有一些标准方法来实现这一点。无论如何，thanx！！不实际上，当单击通知时，如何确定当前显示的是哪个viewcontroller和哪个navigationController…？？只需在AppDelegate或UserDEfault中创建一个BOOL变量，保存这一个值并将其从true切换为flase即可。。当在那个时候发生通知时，检查是否为true，然后只调用第二个方法并将该变量设置为false，否则调用第一个方法并将该变量设置为true…我很早就想到了standardUserDefaults，但后来我认为会有一些标准方法来实现这一点。无论如何，thanx！！
