# Push Payload Receivers

### Handling Push Notification Click Events in iOS with Netmera SDK

Netmera SDK automatically collects **Click Push Events**, allowing you to track when users interact with notifications. However, if you experience issues with collecting these events, it’s important to ensure that your app is properly configured to handle them.

### Implementing `UNUserNotificationCenter` Delegate

Set up the `UNUserNotificationCenter.delegate` at the **beginning** of the `didFinishLaunchingWithOptions` method in your `AppDelegate` file.

{% tabs %}
{% tab title="Swift" %}

```swift
// In didFinishLaunchingWithOptions (AppDelegate.swift)
if #available(iOS 10.0, *) {
    UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
} else {
    // Fallback on earlier versions
}
```

{% endtab %}

{% tab title="Objective-C" %}

```objectivec
// In didFinishLaunchingWithOptions (AppDelegate.m)
[UNUserNotificationCenter currentNotificationCenter].delegate = self;
```

{% endtab %}
{% endtabs %}

### Handle Push Notification Click Events

Once you’ve set the delegate, Netmera will automatically handle push notification events, including click events. Below are the methods to process push notification click events.

{% tabs %}
{% tab title="Swift" %}

```swift
func userNotificationCenter(
    _ center: UNUserNotificationCenter, 
    didReceive response: UNNotificationResponse, 
    withCompletionHandler completionHandler: @escaping () -> Void
) {
    // NetmeraPushObject(dictionary: response.notification.request.content.userInfo)
    // object.alert.body                  // Push Text
    // object.alert.title                 // Push Title
    // object.action.deeplinkURL          // Push Deeplink
    // object.customDictionary            // Custom JSON
}
```

{% endtab %}

{% tab title="Objective-C" %}

```objectivec
- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
  didReceiveNotificationResponse:(UNNotificationResponse *)response 
            withCompletionHandler:(void (^)(void))completionHandler
{
    // NetmeraPushObject *object = [[NetmeraPushObject alloc] initWithDictionary:response.notification.request.content.userInfo];
    // object.alert.body                   // Push Text
    // object.alert.title                  // Push Title
    // object.action.deeplinkURL           // Push Deeplink
    // object.customDictionary             // Custom JSON
}
```

{% endtab %}
{% endtabs %}

### Push Notification Received

To capture push notifications when the app is in the background or foreground, you can implement the following methods. This method will return latest push object received by device.

{% tabs %}
{% tab title="Swift" %}

```swift
func application(
    _ application: UIApplication, 
    didReceiveRemoteNotification userInfo: [AnyHashable: Any], 
    fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void
) {
    // Netmera.recentPushObject()?.alert.body                  // Push Text
    // Netmera.recentPushObject()?.alert.title                 // Push Title
    // Netmera.recentPushObject()?.action.deeplinkURL          // Push Deeplink
    // Netmera.recentPushObject()?.customDictionary            // Custom JSON
}
```

{% endtab %}

{% tab title="Objective-C" %}

```objectivec
- (void)application:(UIApplication *)application 
  didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    // [Netmera recentPushObject].alert.body                   // Push Text
    // [Netmera recentPushObject].alert.title                  // Push Title
    // [Netmera recentPushObject].action.deeplinkURL           // Push Deeplink
    // [Netmera recentPushObject].customDictionary             // Custom JSON
}

```

{% endtab %}
{% endtabs %}

### Push Notification Received on Foreground

This method allows you to handle push notifications when the app is in the foreground.

{% tabs %}
{% tab title="Swift" %}

```swift
func userNotificationCenter(
    _ center: UNUserNotificationCenter, 
    willPresent notification: UNNotification, 
    withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void
) {
    completionHandler(.alert)
}
```

{% endtab %}

{% tab title="Objective-C" %}

```objectivec
- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
  willPresentNotification:(UNNotification *)notification 
  withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
    completionHandler(UNNotificationPresentationOptionAlert);
}
```

{% endtab %}
{% endtabs %}

### Retrieve Device Push Token

To get the push token, use the following method:

{% tabs %}
{% tab title="Swift" %}

```swift
func application(
    _ application: UIApplication, 
    didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
) {
}
```

{% endtab %}

{% tab title="Objective-C" %}

```objectivec
- (void)application:(UIApplication *)application 
  didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
}
```

{% endtab %}
{% endtabs %}
