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

self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

self.window.backgroundColor = [UIColor colorWithRed:249/255.0 green:249/255.0 blue:249/255.0 alpha:1];

[[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:23/255.0 green:180/255.0 blue:237/255.0 alpha:1]];

[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];

ViewController *viewController = [[ViewController alloc]init];

self.window.rootViewController = viewController;

[self.window makeKeyAndVisible];

if ([[UIApplication sharedApplication]currentUserNotificationSettings].types != UIUserNotificationTypeNone) {

[self addLocalNotification];

}else{

[[UIApplication sharedApplication]registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];

}

// Override point for customization after application launch.

return YES;

}

-(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings

{

if (notificationSettings != UIUserNotificationTypeNone) {

[self addLocalNotification];

}

-(void)addLocalNotification{

UILocalNotification *notification = [[UILocalNotification alloc]init];

notification.fireDate = [NSDate dateWithTimeIntervalSinceNow:2.0];

notification.repeatInterval = 2;

notification.alertBody = @"该睡觉了哦！~~";

notification.applicationIconBadgeNumber = 2;

notification.alertAction = @"打开应用";

notification.alertLaunchImage = @"Default";

notification.soundName = @"msg.caf";

notification.userInfo = @{@"id":@1,@"name":@"dsn"};

[[UIApplication sharedApplication]scheduleLocalNotification:notification];

}

- (void)applicationWillEnterForeground:(UIApplication *)application {

[[UIApplication sharedApplication]setApplicationIconBadgeNumber:0];

// Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.

}
