Parse - Calling cloud code on app installation - ios

Question

I have created some cloud code for my Parse database and I want it to be called when the a user installs the app. I have implemented Push so I want it to get triggered when the user registers for Push Notifications. I also want to be able to pass the "deviceToken" into my cloud function.
Here is the function that I have so far:
Parse.Cloud.define("newListing", function(request, response) {
var ListingClass = Parse.Object.extend("Listings");
var listing = new ListingClass();
listing.set("Name","--");
listing.set("DeviceID",request.params.param_DeviceID);
listing.save(null,{
success:function(listing) {
response.success(listing);
},
error:function(error) {
response.error(error);
}
});
});
Summary:
I want to call the cloud function "newListing" when the user registers for Push Notifications
Any ideas? Thanks!

Answer 1

You only get the deviceToken when the didRegisterForRemoteNotificationsWithDeviceToken method is called in the AppDelegate, so place your cloud code calling function in there.
Swift code:
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
// Do your normal token handling to set the device token in the Installation and save to Parse.com
let currentInstallation = PFInstallation.currentInstallation()
currentInstallation.setDeviceTokenFromData(deviceToken)
currentInstallation.saveInBackground()
// Call your cloud code function
let deviceTokenAsString = .... // You need to implement this code
PFCloud.callFunctionInBackground("newListing", withParameters: ["param_DeviceID": deviceTokenAsString]) { results, error in
// Error handling, and any other functionality you need when your cloud function is complete
}
}

Below is a solution that I came up with that didn't require the app to be modified. This cloud function gets called after a new installation occurs.
Parse.Cloud.afterSave(Parse.Installation, function(request, response) {
var newID = request.object.get("deviceToken");
var query = new Parse.Query("Listings");
query.equalTo("DeviceID", newID);
query.find({
success: function(results) {
if(results.length > 0){
response.success("ID already exists");
}else{
var ListingClass = Parse.Object.extend("Listings");
var listing = new ListingClass();
listing.set("Name","--");
listing.set("DeviceID",newID);
listing.save(null,{
success:function(listing) {
response.success(listing);
},
error:function(error) {
response.error(error);
}
});
}
},
error: function() {
response.error("ID fail");
}
});
});
