How to add button to Apple WatchKit Long Look notification - ios

Question

Can someone please talk me through adding a button to a long-look local notification? I'm new to both the watch kit and notifications.
The long-look is functioning correctly. I'm setting up a UILocalNotification in my host app, setting the alertBody, category, userInfo, etc. and sending it off.
In my notification controller I'm setting everything up in didReceiveLocalNotification and it's working fine.
It seems, from my research, that I'm supposed to somehow add the button to the notification and use the method handleActionWithIdentifier: forLocalNotification but I'm unclear exactly how to do this.
I'm writing in Objective-C. Thanks

Here is notification payload I'm using:
{
"aps": {
"alert": {
"body": "Hi! How you doing? This is a test message. Press 'Reply' button to reply. Thanks!",
"title": "Petya"
},
"category": "newMessage"
},
"WatchKit Simulator Actions": [
{
"title": "Reply",
"identifier": "replyPressed"
}
],
}
Create custom notification subclass and override following method and don't forget to set that subclass in corresponding storyboard controller:
override func didReceiveRemoteNotification(remoteNotification: [NSObject : AnyObject], withCompletion completionHandler: (WKUserNotificationInterfaceType) -> Void) {
if let aps = remoteNotification["aps"] as? NSDictionary {
if let alert = aps["alert"] as? NSDictionary {
if let title = alert["title"] as? String {
titleLabel.setText(title)
}
if let body = alert["body"] as? String {
bodyLabel.setText(body)
}
}
}
completionHandler(WKUserNotificationInterfaceType.Custom)
}
After that in your notification custom button with title 'Reply' will appear. And when you press it it will launch watch app main interface controller and call handleActionWithIdentifier:localNotification: or handleActionWithIdentifier:remoteNotification:, depends on kind of notification you received. You have to override it like that:
override func handleActionWithIdentifier(identifier: String?, forRemoteNotification remoteNotification: [NSObject : AnyObject]) {
println("identifier: \(identifier)")
println("remoteNotification: \(remoteNotification)")
if identifier == "replyPressed" {
if let aps = remoteNotification["aps"] as? NSDictionary {
if let alert = aps["alert"] as? NSDictionary {
if let title = alert["title"] as? NSString {
let context = Context()
context.object = title
pushControllerWithName(kTCChatRoomControllerIdentifier, context: context)
}
}
}
}
}
P.S. Context is my own class for passing data between WKInterfaceController's subclasses
Hope this will help you!)

The Notification Essentials section of the Apple Watch Programming Guide describes how to add action buttons to Long-Look notifications for local notifications.
Basically, you need to create a UIMutableUserNotificationAction for every button that you want to add to your Long-Look interface, along with a category for your local notification. This is done in the App Delegate of your iOS app, when you register for notifications. Listing 15-1 in that guide shows exactly how to do it. Then, in the storyboard for your Apple Watch app, set your notification's category to the category you just created. The next section of the guide, "Responding to Taps in Action Buttons," should hopefully tell you everything you need to know in order to either launch your WatchKit app, or execute a task in the background on the iPhone.
