在进行iOS上开发，发现Flutter创建的项目不走didRegisterForRemoteNotificationsWithDeviceToken，起初以为是没有设置UNUserNotificationCenterDelegate，后来发现AppDelegate是继承于FlutterAppDelegate的，
也就是将原生的UIApplicationDelegate的方法都会被FlutterPlugin拦截，即使我们不实现didRegisterForRemoteNotificationsWithDeviceToken，我觉得应该有两种方法可以实现：第一种是需要重写父类的推送方法。第二种就是在dart文件中监听系统代理，通过通道回调appdelegate来实现
下面是方法一的实现：
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
) -> Bool {
GeneratedPluginRegistrant.register(with: self);
//设置、注册远程推送
self.requestAuthorization(application: application);
//Flutter原生交互通道
self.BPushChannel();
//注册BPush通道
BPush.registerChannel(launchOptions, apiKey: BPushKey, pushMode: BPushMode.development, withFirstAction: "打开", withSecondAction: "关闭", withCategory: nil, useBehaviorTextInput: true, isDebug: true);
//禁用地理位置信息推送
BPush.disableLbs();
//
let userInfo = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification]
if userInfo != nil {
BPush.handleNotification(userInfo as? [AnyHashable : Any])
}
return super.application(application, didFinishLaunchingWithOptions: launchOptions);
}
//MARK:注册远程推送通知
func requestAuthorization(application: UIApplication) {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate;
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert]) { (granted, error) in
if granted == true {
DispatchQueue.main.async {
application.registerForRemoteNotifications()
}
}
}
} else if #available(iOS 8.0, *) {
let types:UIUserNotificationType = [.badge , .alert , .sound]
let settings:UIUserNotificationSettings = UIUserNotificationSettings(types: types, categories: nil)
application.registerUserNotificationSettings(settings)
} else {
let types:UIRemoteNotificationType = [UIRemoteNotificationType.alert, UIRemoteNotificationType.badge, .sound]
application.registerForRemoteNotifications(matching: types)
}
}
//百度推送通道
func BPushChannel() -> Void {
//
let controller = self.window.rootViewController
//建立rootViewController和Flutter的通信通道
let pushChannel = FlutterMethodChannel.init(name: channelNameForPush, binaryMessenger:controller as! FlutterBinaryMessenger)
pushChannel.setMethodCallHandler { (FlutterMethodCall, FlutterResult) in
print("pushChannel");
}
//绑定channelId到服务器
let pushBind = FlutterMethodChannel.init(name:channelNameForPushBind, binaryMessenger: controller as! FlutterBinaryMessenger)
pushBind.setMethodCallHandler { (FlutterMethodCall, FlutterResult) in
if(self.channelId.isEmpty){
print("channelId为空");
FlutterResult(FlutterMethodNotImplemented);
} else{
print("channelId",self.channelId);
let dic : Dictionary<String,String> = ["channelId":self.channelId];
let data = try? JSONSerialization.data(withJSONObject: dic, options: [])
let encodingStr = String(data: data!, encoding: String.Encoding.utf8)!
//将信息传到Flutter，
FlutterResult(encodingStr);
}
}
}
// 重写远程推送通知 注册成功
override func application(_ application: UIApplication , didRegisterForRemoteNotificationsWithDeviceToken deviceToken:Data) {
// 向云推送注册 device token
print("deviceToken = %@", deviceToken);
BPush.registerDeviceToken(deviceToken as Data)
// 绑定channel.将会在回调中看获得channnelid appid userid 等
BPush.bindChannel(completeHandler: { (result, error) -> Void in
if ((result) != nil){
self.channelId = BPush.getChannelId();
BPush.setTag("MyTag", withCompleteHandler: { (result, error) -> Void in
if ((result) != nil){
}
})
}
})
super.application(application, didRegisterForRemoteNotificationsWithDeviceToken:deviceToken)
}
// 重写注册失败
override func application(_ application: UIApplication , didFailToRegisterForRemoteNotificationsWithError error: Error ) {
print("deviceToken = %@", error)
super.application(application, didFailToRegisterForRemoteNotificationsWithError: error)
}
