# Widget and In-App Messages

### Pop-up and In-App Message Presentation Behavior

All push notifications in Netmera work automatically—no additional coding is required. However, you can **customize** pop-up presentations and **listen to push callbacks**.

By default, when a popup notification or in-app message is received:

* If the app is in the **foreground**, the SDK displays pop-up notifications and in-app messages **immediately**.
* If the app is in the **background**, the SDK shows them **when the app returns to the foreground.**

### Receiving Popups and In-App Messages in the Background

To receive popups or in-app messages when the application is in the background, you need to enable **Remote Notifications** under **Background Modes** in **Capabilities**.

### Pop-up Presentation Logic

If a pop-up is received when pop-up presentation is disabled by your code, SDK will store it, and present whenever pop-up presentation is re-enabled. If multiple pop-up notifications are received during that period, SDK stores the most recent notification, and present only that one.

### Enable / Disable Immediate Presentations

To prevent immediate pop-up presentation (e.g., during video playback, gaming, or checkout), use:

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

```swift
// Call this method to disable immediate popup presentation
Netmera.setEnabledPopupPresentation(false)

// Call this method to re-enable immediate popup presentation
Netmera.setEnabledPopupPresentation(true)
```

{% endtab %}

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

```objectivec
// Call this method to disable immediate popup presentation
[Netmera setEnabledPopupPresentation:false];

// Call this method to re-enable immediate popup presentation
[Netmera setEnabledPopupPresentation:true];
```

{% endtab %}
{% endtabs %}

### Devices in Low Battery Mode

Devices **cannot** receive popups or in-app messages while the application is closed or killed if the device is in **low battery mode**, as this mode disables background application refresh.

### Troubleshooting Pop-up and In-App Message Issues

If you are facing issues with receiving pop-ups or in-app messages, follow the troubleshooting steps below:

**1. Increase Session Expiry Duration**

Increase the session expiration interval to give the app more time to display pop-ups:

1. Navigate to **Developer > App Info** in your dashboard.
2. Under **App Config**, increase the **Session Expire Interval** by 1.
3. Click **Apply** to save the changes and retry the pop-up.

**2. Check for Conflicting Code Settings**

Ensure that no part of your code is setting values to **false** that may interfere with pop-up functionality.

**3. Verify Delegate Method Placement**

The `UNUserNotificationCenter` delegate method must be placed at the **top** of the `didFinishLaunchingWithOptions` function to ensure proper notification handling:

```swift
// Ensure this line is at the top of didFinishLaunchingWithOptions
if #available(iOS 10.0, *) {
    UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
} else {
    // Fallback for earlier iOS versions
}
```

**4. Ensure Proper Initialization with Third-Party Tools**

If you're integrating third-party tools, ensure that **Netmera is initialized** at the beginning of your project to avoid conflicts.

**5. Handling Multiple Pop-ups**

Displaying multiple pop-ups at once can cause loading issues. Ensure that your app logic accounts for displaying one pop-up at a time to avoid this problem.

**6. Device Storage Limitations**

Pop-ups may not display correctly if the device's storage is near full. Ensure that your device has enough available storage for proper notification delivery.
