前言:
这里的通知都是以远程通知为例子,iOS通知设置在AppDelegate中,其设置好了以后WatchOS会直接复制其在iOS上的通知内容和处理按钮。但是事后的逻辑代码是分开的。通过本文你可以达到的结果如下图:
当然WatchOS上的通知也会是有两个按钮。
借鉴:iOS 玩转推送通知
效果图
写在AppDelegate
#pragma mark 注册远程通知
- (void)registerNotification{
UIMutableUserNotificationAction *action1 = [[UIMutableUserNotificationAction alloc]init];
action1.identifier = startEventString;
action1.title = @"Start Record Now";
action1.activationMode = UIUserNotificationActivationModeForeground;//前台
action1.authenticationRequired = YES;//开始事件必须解锁
/*
destructive属性设置后,在通知栏或锁屏界面左划,按钮颜色会变为红色
如果两个按钮均设置为YES,则均为红色(略难看)
如果两个按钮均设置为NO,即默认值,则第一个为蓝色,第二个为浅灰色
如果一个YES一个NO,则都显示对应的颜色,即红蓝双色 (CP色)。
*/
action1.destructive = NO;
UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc]init];
action2.identifier = notEventString;
action2.title = @"No I'm Not";
action2.activationMode = UIUserNotificationActivationModeBackground;//后台
action1.authenticationRequired = NO;//取消无需解锁
action2.destructive = YES;
//创建动作(按钮)的类别集合
UIMutableUserNotificationCategory *category = [[UIMutableUserNotificationCategory alloc] init];
//这组动作的唯一标示(kNotificationCategoryIdentifile为我定义的一个宏,可自行定义)
category.identifier = @"NoticeIdentifier";
//最多支持两个,如果添加更多的话,后面的将被忽略
[category setActions:@[action1, action2] forContext:(UIUserNotificationActionContextDefault)];//必须是Default才可以在Watch上出现多个按钮
//创建UIUserNotificationSettings,并设置消息的显示类类型
UIUserNotificationSettings *uns = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound) categories:[NSSet setWithObject:category]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
[[UIApplication sharedApplication] registerUserNotificationSettings:uns];
}
特别注意 [category setActions:@[action1, action2] forContext:(UIUserNotificationActionContextDefault)];//必须是Default才可以在Watch上出现多个按钮
同样特别特别注意 category.identifier = @"NoticeIdentifier";
这里的category identifier要与apns发来的json中的category相同,而且若想用WatchOS上的通知也与iOS相同,WatchOS上也会设置一个标示与这个category identifier相同,具体的WatchOS的会在后面介绍。
同样写在AppDelegate 注册远程通知后的回调
#pragma mark RemoteNotification Delegate
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{ //APP在前台时候处理推送消息
NSLog(@"userinfo:%@",userInfo);
NSLog(@"收到推送消息:%@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
apnsDic = [NSMutableDictionary dictionaryWithDictionary:userInfo];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Notice" message:@"the Air is changed,Are you cooking?" delegate:self cancelButtonTitle:@"NO" otherButtonTitles:@"Start Record", nil];
[alert show];
}
- (void)application:(UIApplication *)application handleActionWithIdentifier:(nullable NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo withResponseInfo:(NSDictionary *)responseInfo completionHandler:(void(^)())completionHandler NS_AVAILABLE_IOS(9_0) __TVOS_PROHIBITED{
NSLog(@"responsinfo is %@",identifier);
if ([identifier isEqualToString:notEventString]) {
}
else{
}
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *) error {
NSLog(@"Registfail%@",error);//注册通知失败
}
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
NSLog(@"token is %@",deviceToken);//这里的Token就是我们设备要告诉服务端的Token码
}
iOS的远程通知介绍完了,接下来介绍WatchOS上的
在Watch APP interface.storyboard里面,会有通知的这一个interface,点击左侧的箭头
1
右侧会有其属性:
2
这里将Name填为我们在iOS代码中一致的identifier,这样在apns发来信息中含有"category":"..."这个信息后,iOS会自动识别其通知类型,并将其同步到WatchOS,watchOS只需要name一致,然后可以在通知对应的NotificationController中修改各类属性就好了。
在iOS中点击通知的按钮会有处理回调函数,同样在watchOS中也有:
- (void)handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)remoteNotification{
NSLog(@"remote %@ and identifier %@",remoteNotification,identifier);
}
