Let's integrate our UIKIT in few minutes
Notification Configuration#
iOS configuration#
Step 1: Open Info.plist file and add the notification related code as mentioned below.
...
<key>UIBackgroundModes</key>
<array>
<string>fetch</string>
<string>processing</string>
<string>remote-notification</string>
<string>voip</string>
</array>
...
Step 2: Enable the following options to receive push notification when app is in background/killed.
- Open Xcode -> Signing & Capabilities -> Background Modes. Make sure you enabled the following checkboxes
Step 3: Go to Xcode -> Signing & Capabilities. Click + Capabality on the top left corner of the sub window.
And serach for Push Notification and add it.
Note: Ignore this step if you already have
Push Notificiationoption.
Step 4: Open AppDelegate.mm and add the below mentioned codes.
...
// add the below imports
#import <PushKit/PushKit.h>
#import <RNVoipPushNotificationManager.h>
#import "RNCallKeep.h"
#import <CallKit/CallKit.h>
#import <RNKeyEvent.h>
#import <AVFoundation/AVFoundation.h>
#import <UIKit/UIKit.h>
...

RCTBridge *bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];
...
}
// add the below mentioned codes just before the last `@end` line of the file.
