iOS本地通知打开特定视图

Question

我想打开一个特定的视图，因为否则发出通知是没有意义的。 在stackoverflow上，大多数问题是关于选项卡式应用程序..但我有一个视图控制器。

这是我当地的通知：

UILocalNotification *notification = [UILocalNotification new];
notification.alertBody = @"Test";
notification.applicationIconBadgeNumber = 1;

[[UIApplication sharedApplication] presentLocalNotificationNow:notification];

这是我为我的app delegate.m

找到的代码

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

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.

self.mainVC = [[UIViewController alloc] initWithNibName:@"MyTestViewController" bundle:nil];
self.window.rootViewController = self.mainVC;
[self.window makeKeyAndVisible];

application.applicationIconBadgeNumber = 0;
return YES;
}

我尝试将其集成到我的应用中，但这是错误：在'AppDelegate'类型的对象上找不到属性'mainVC'。

我想打开'MyTestViewController'。有人可以向我解释我该怎么办？非常感谢你

Answer 1

除非你在某个地方声明它，否则没有mainVC这样的东西。假设您想要设置一个MyTestViewController类的视图控制器，您可以这样做：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    MyTestViewController *myTestVC = [MyTestViewController new];
    self.window.rootViewController = myTestVC;
    [self.window makeKeyAndVisible];
    return YES;
}

如果您的应用是单一视图，您可以使用Xcode中的“单一视图应用程序”模板开始。

导入

#import MyTestViewController.h

创建一个属性

@property(nonatomic, strong) MyTestViewController * myTestViewController;

和

self.myTestViewController = [[MyTestViewController alloc] initWithNibName:@"MyTestViewController" bundle:nil];
self.window.rootViewController = self.myTestViewController;

试一试 - ＆gt;

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif {
    //present your controller here, for example
    self.myTestViewController = [[UIViewController alloc] initWithNibName:@"MyTestViewController" bundle:nil];
    [self.window.rootViewController pushViewController:self.myTestViewController animated:YES];
}
