Swift Notification
这里我们先大概梳理下普通通知的使用方式:
- 注册监听
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(test(_ :)), name: NSNotification.Name(rawValue: "TESTNOTIFY"), object: "the object content")
}
- 实现监听后执行的方法
func test(_ notify: Notification) {
print(notify.object ?? "nil")
}
- 发送通知
NotificationCenter.default.post(name: Notification.Name(rawValue: "TESTNOTIFY"), object: "hello")
问题
大家会发现监听的时候实际是做了两步，代码比较分散，不容易管理. 这个也正是ZRNotify能帮我们解决的部分
pod方式安装
pod 'ZRNotify', '~> 0.0.5'
使用
调用方式一: 分开监测
lazy var zrNotify: ZRNotify = {
var zrnotify = ZRNotify()
zrnotify.on("ScheduleA", notify: { notify in
print(notify.object ?? "nil object")
}).on("ScheduleB", notify: { notify in
print(notify.object ?? "nil object")
}).on("ScheduleC", notify: { notify in
print(notify.object ?? "nil object")
})
return zrnotify
}()
调用方式二: 统一监测
lazy var zrNotifys: ZRNotify = {
var zrnotify = ZRNotify()
zrnotify.ons(["Schedule1", "Schedule2", "Schedule3"], notify: { notify in
print(notify.object ?? "nil object")
})
return zrnotify
}()
初始化通知接收
override func viewDidLoad() {
super.viewDidLoad()
// 初始化
zrNotify.opStatusForAll(true)
zrNotifys.opStatusForAll(true)
// 测试
NotificationCenter.default.post(name: Notification.Name(rawValue: "ScheduleA"), object: "hello ScheduleA")
NotificationCenter.default.post(name: Notification.Name(rawValue: "ScheduleB"), object: nil)
NotificationCenter.default.post(name: Notification.Name(rawValue: "ScheduleC"), object: "hello ScheduleC")
// 测试
NotificationCenter.default.post(name: Notification.Name(rawValue: "Schedule1"), object: "hello Schedule1")
NotificationCenter.default.post(name: Notification.Name(rawValue: "Schedule2"), object: nil)
NotificationCenter.default.post(name: Notification.Name(rawValue: "Schedule3"), object: "hello Schedule3")
}
取消监听
zrNotify.remove("ScheduleA")
