前言
通过这篇文章你会学到：
- 弄出本地通知
- 弄出有选项操作的通知
- 类似微信的快速回复
本地通知
我写成了函数的形式方便设置
func setNotification(body:String,timeToNotification:Double,soundName:String,category:String) -> UILocalNotification {
let localNotification:UILocalNotification = UILocalNotification()
localNotification.alertAction = "滑动查看信息"
localNotification.alertBody = body
//在mainBundle的短于30秒的播放文件,否则就会是系统默认声音
localNotification.soundName = soundName
localNotification.fireDate = NSDate(timeIntervalSinceNow: timeToNotification)
//下面这条category语句是对应下面的“有选项的本地操作”章节
localNotification.category = category
return localNotification
}
在appDelegate里填下
//请求通知权限
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound , .Alert , .Badge], categories: nil))
}
使用时：
//设置10秒的提醒
let completeNotification = setNotification("时间到了，已完成任务",timeToNotification: 10,soundName: "提醒音乐.mp3",category: nil)
UIApplication.sharedApplication().scheduleLocalNotification(completeNotification)
10秒后
通知
有选项的本地操作
效果如图：
侧滑出选项
设置Notification Action 和 Category
//MARK: - 提醒操作 设置
let notificationActionOk : UIMutableUserNotificationAction = UIMutableUserNotificationAction()
notificationActionOk.identifier = "completeRemindRater"
notificationActionOk.title = "再工作一会儿"
//是否取消提醒
notificationActionOk.destructive = false
//是否需要权限，例如锁屏的时候，执行操作是否需要解锁再执行
notificationActionOk.authenticationRequired = false
//启动app还是后台执行
notificationActionOk.activationMode = UIUserNotificationActivationMode.Background
let notificationActionRestNow: UIMutableUserNotificationAction = UIMutableUserNotificationAction()
notificationActionRestNow.identifier = "relaxNow"
notificationActionRestNow.title = "休息"
notificationActionRestNow.destructive = false
notificationActionRestNow.authenticationRequired = false
notificationActionRestNow.activationMode = UIUserNotificationActivationMode.Background
//MARK: -Notification Category 设置
let notificationCompleteCategory: UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
//记住这个identifier ，待会用
notificationCompleteCategory.identifier = "COMPLETE_CATEGORY"
notificationCompleteCategory.setActions([notificationActionOk,notificationActionRestNow], forContext: .Default)
notificationCompleteCategory.setActions([notificationActionOk,notificationActionRestNow], forContext: .Minimal)
//请求用户允许通知
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound , .Alert , .Badge], categories: NSSet(array: [notificationCompleteCategory]) as? Set<UIUserNotificationCategory>))
接着在使用时，则将category参数的nil改为"COMPLETE_CATEGORY"
//跟之前的一样,10秒后出通知，但category不同
let completeNotification = setNotification("时间到了，已完成任务",timeToNotification: 10,soundName: "提醒铃声.mp3",category: "COMPLETE_CATEGORY")
UIApplication.sharedApplication().scheduleLocalNotification(completeNotification)
在appDelegate使用下面method处理按下的选项
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
print("按下的选项的identifier是：\\\\(identifier)")
}
按下休息时，终端显示按下的选项的identifier是：relaxNow
信息下滑有选项
通知快速回复
实现类似微信的快速回复
效果如图：
实现基本同上面的选项通知一样，就是创建时修改 action的behavior为.TextInput:
let replyAction = UIMutableUserNotificationAction()
replyAction.title = "回复"
replyAction.identifier = "inline-reply"
replyAction.activationMode = .Background
replyAction.authenticationRequired = false
replyAction.behavior = .TextInput
接着像设置有选项的操作那样设置Category
let notificationCategory:UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
notificationCategory.identifier = "REPLY_CATEGORY"
notificationCategory.setActions([replyAction], forContext: UIUserNotificationActionContext.Default)
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Sound , .Alert , .Badge], categories: NSSet(array: [notificationCategory]) as? Set<UIUserNotificationCategory>))
设置提醒，使用本地操作时那个函数setNotification
let replyNotification = setNotification("说些什么吧", timeToNotification: 10, soundName: "提醒音乐.mp3" , category: "REPLY_CATEGORY")
UIApplication.sharedApplication().scheduleLocalNotification(replyNotification)
快速回复
处理回复：则在appDelegate下添加：
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, withResponseInfo responseInfo: [NSObject : AnyObject], completionHandler: () -> Void) {
if let response = responseInfo[UIUserNotificationActionResponseTypedTextKey]{
let responseText = response as! String
print("\(responseText)")
}
completionHandler()
}
在快速回复如上图打下Hello,world!，终端就会出现：
终端
一些tips
//取消本地通知
UIApplication.sharedApplication().cancelAllLocalNotifications()
//修改App Icon上的数字如下图中右上角的数字
UIApplication.sharedApplication().applicationIconBadgeNumber = 1
icon
最后
通知的实现基本就如此了。
