Firebase Custom Messages iOS - ios

Question

I'm referring to the interpreting messages portion in https://firebase.google.com/docs/cloud-messaging/ios/receive .
Where in my code can I change the text for notifications in Firebase?

Answer 1

In order to send a push notification to a device, You need to have a script (or a piece of code) ideally hosted on a server that would send a push notification on your behalf.
There you can customize the message and even play an audio upon receiving a notification.
Here is a code snippet in java that can be used to send a push notification to a device (or a group of devices).
private Map sendPush(String to, String from, String title, String message,
String sound) throws IOException {
sound = (sound != null) ? sound : "default"; // set default audio file name
// Creating the URL and connection
URL url = new URL(FCM_URL); // your firebase URL
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "key=" + FCM_KEY); // the firebase project key
conn.setDoOutput(true);
// set the notification body
Map<String, String> notificationBody = new HashMap();
notificationBody.put("title", title); // notification title
notificationBody.put("body", message); // notification message
notificationBody.put("sound", sound);
notificationBody.put("badge", "1");
Map<String, String> dataBody = new HashMap();
dataBody.put("sender", from); // sender id
Map<String, Object> pushBody = new HashMap();
pushBody.put("notification", notificationBody);
pushBody.put("data", dataBody);
pushBody.put("to", to); // receiver(s) id
pushBody.put("priority", "high");
// convert your dictionary to json string using Google Gson library (similar to JsonSerialization class in swift)
String input = new Gson().toJson(pushBody);
// write input bytes in request body
try (OutputStream os = conn.getOutputStream()) {
os.write(input.getBytes());
os.flush();
}
StringBuilder responseString;
Reader reader = new InputStreamReader(conn.getInputStream()); // send request and receive response
// parse response
try (BufferedReader in = new BufferedReader(reader)) {
String inputLine;
responseString = new StringBuilder();
while ((inputLine = in.readLine()) != null) {
responseString.append(inputLine);
}
}
// using Google Gson to convert json string into Map (similar to JsonSerialization class in swift)
Map<String, Object> responseObject = new Gson().fromJson(responseString.toString(),
Map.class);
return responseObject;
}
Since this is a java code, so i have hosted it in a java application deployed on Apache Tomcat Server.
You can find several similar implementations in various languages like php or node.js etc.
Hope this helps

first create p.12 certificate and upload in firebase ->project settings ->cloud messaging tab ->select your iOS app ->add APNS certificate.
A. Create a (.certSigningRequest) CSR file
Open Keychain Access from Utilities
From Keychain Access toolbar select Keychain Access -> Preference
In the pop up window select Certificates tab
Set both “Online Certificate Status Protocol” and “Certificate Revocation List” to “Off"
Close this window
Now from toolbar, open Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority
Enter email address and common name that you used to register in the iOS Developer Program
Keep CA Email blank and select “Saved to disk” and “Let me specify key pair information”
Click Continue
Choose a filename & destination on your hard drive
Click Save
In the next window, set “Key Size” value to “2048 bits”
Set “Algorithm” to “RSA”
Click Continue
This will create and save your certSigningRequest file (CSR) to your hard drive. A public and private key will also be created in Keychain Access with the Common Name entered.
B. Create ".cer" file in iOS developer account
Login to apple developer account Click “Certificates, Identifiers & Profiles”
Click “Provisioning Profiles”
In the “Certificates” section click “Production”
Click the “Add” (+) button at the top-right of the main panel
Now, choose “App Store and Ad Hoc”
Click Continue
Click “Choose File” & find CSR file you’ve made from your hard drive
Click Generate
Click Download to get the file
C. Install .cer and generate .p12 certificate
Find .cer file you’ve downloaded and double-click
Set Login drop-down to “login" and Click Add
Open up KeyChain Access and you'll find profile created in Step A
You can expand “private key” profile (shows certificate you added)
Select only these two items (not the public key)
Right click and click “Export 2 items…” from popup
Now make sure file format is “.p12” and choose filename and destination on your hard drive
Click Save. Now, you’ll be prompted to set a password but keep these both blank
Click OK. Now, you have a .p12 file on your hard drive
and open your Xcode project and select target->capabilities->pusnotification->on
next do this stuff https://firebase.google.com/docs/cloud-messaging/ios/receive
next push message from firebase cloud messaging console with message and title and select your app target->user segment->your app.
then your app will able
