//发通知
NotificationCenter.default.post(name: Notification.Name("yjbindWechat"), object: nil)
//接收分享图片的通知
NotificationCenter.default.addObserver(self, selector: #selector(yjpopalertcancelfirmAction), name: Notification.Name("yjpopalertcancel"), object: nil)
// NotificationCenter.default.addObserver(self, selector: #selector(yjTopalertcancelfirmAction), name: Notification.Name("yjTopalertcancel"), object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(yjLookcancelfirmAction), name: Notification.Name("yjLookcancel"), object: nil)
/// 析构函数.类似于OC的 dealloc
deinit {
// 清除指定通知的方法
// UNUserNotificationCenter.current().removeDeliveredNotifications(withIdentifiers: ["yjbindWechat"])
/// 移除通知
NotificationCenter.default.removeObserver(self)
}
创建通知中心
设置监听方法
设置通知的名字
NotificationCenter.default.addObserver(self, selector: #selector(test), name: NSNotification.Name(rawValue:"isTest"), object: nil)
实现通知监听方法
@objc func test(nofi : Notification){
let str = nofi.userInfo!["post"]
print(String(describing: str!) + "this notifi")
}
点击发送通知进行
override func touchesBegan(_ touches: Set, with event: UIEvent?) {
NotificationCenter.default.post(name: NSNotification.Name("isTest"), object: self, userInfo: ["post":"NewTest"])
}
最后要记得移除通知
deinit {
/// 移除通知
NotificationCenter.default.removeObserver(self)
}
