ios--本地通知

標籤：

1. ios8發送本地通知，需要先註冊本地通知。

2. if ([[UIApplication sharedApplication]currentUserNotificationSettings].types==UIUserNotificationTypeNone) 當前應用的本地通知類型，UIUserNotificationTypeNone沒有註冊本地通知     註冊是系統級的，跟程式沒有關係，當程式刪除之後重新安裝依然是授權過了，綁定了id。

   //每次執行授權操作的時候，都會走這個代理- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings; 

1.     UIUserNotificationTypeNone    = 0,      // 申請不得在收到通知時提出任何使用者介面
2.     UIUserNotificationTypeBadge   = 1 << 0, // 該應用程式可在收到通知時將其表徵圖標記為
3.     UIUserNotificationTypeSound   = 1 << 1, // 該應用程式可在收到通知後發出聲音
4.     UIUserNotificationTypeAlert   = 1 << 2, // 該應用程式可在收到通知後顯示警報
5. (對應標記，聲音，橫幅)

 

 

實際的開發分為兩種情況1.當應用程式退出到後台,通過點擊推送進入程式。這個時候可以通過使用-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification;根據這個方法擷取推送的資訊。2.當應用程式被殺死的時候，點擊推送進來的時候會重新載入介面。- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;可以根據launchOptions擷取推送內容。//接收通知參數UILocalNotification *notification=[launchOptions valueForKey:UIApplicationLaunchOptionsLocalNotificationKey];

　　

-(void)addNotification{    UILocalNotification *notification=[[UILocalNotification alloc]init];    notification.fireDate=[NSDate dateWithTimeIntervalSinceNow:10];    [email protected]"通知來咯";    [[UIApplication sharedApplication]scheduleLocalNotification:notification];}

　　

實現一個小功能：當使用者連續1小時不操作會通過本地推送提示使用者操作，每隔1小時提示一次。- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {//通知授權    if ([[UIApplication sharedApplication]currentUserNotificationSettings].types==UIUserNotificationTypeNone) {        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound  categories:nil]];    }}//失去焦點-(void)applicationWillResignActive:(UIApplication *)application{    [self addNotification];}-(void)addNotification{    UILocalNotification *notification=[[UILocalNotification alloc]init];    notification.fireDate=[NSDate dateWithTimeIntervalSinceNow:10];    [email protected]"一分鐘沒有用了";    notification.repeatInterval=NSCalendarUnitMinute;//設定重複的頻率        [[UIApplication sharedApplication]scheduleLocalNotification:notification];}//清空所有的本地通知 [[UIApplication sharedApplication]cancelAllLocalNotifications];
