### Remote Configs

A TapTalk.io project owns a remote configuration, which consists of 3 configuration types: **Core Configs**, **Project Configs**, and **Custom Configs**. A configuration value can be obtained with the respective configuration type's getter method, and will return a Map object. To get a specific value, call the **get** method from the returned dictionary with the respective key. The value obtained will always be in a **String** format and should be converted each according to their uses. Each configuration type will be explained below.

### Core Configs

| **Config Key**         | **Value**                                                                    |
| ---------------------- | ---------------------------------------------------------------------------- |
| chatMediaMaxFileSize   | Number of maximum allowed chat media file size in bytes                      |
| roomPhotoMaxFileSize   | Number of maximum allowed group chat room profile picture file size in bytes |
| userPhotoMaxFileSize   | Number of maximum allowed user profile picture file size in bytes            |
| groupMaxParticipants   | Number of maximum allowed participants in a group chat room                  |
| channelMaxParticipants | Number of maximum allowed participants in a channel                          |

Below is an example to get the value of chatMediaMaxFileSize:

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

```csharp
#import <TapTalk/TapTalk.h>
  
NSDictionary *coreConfigsDictionary = [[TapTalk sharedInstance] getCoreConfigs];
NSString *maxFileSizeString = [coreConfigsDictionary objectForKey:@"maxFileSize"];
NSInteger maxFileSizeValue = [maxFileSizeString integerValue];
```

{% endtab %}
{% endtabs %}

### Project Configs

| **Config Key**     | **Value**                                                                                                                                       |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| usernameIgnoreCase | <p><strong>"0"</strong> if username in the project is case sensitive<br><strong>"1"</strong> if username in the project is case insensitive</p> |

An example to obtain usernameIgnoreCase value:

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

```csharp
#import <TapTalk/TapTalk.h>
  
NSDictionary *projectConfigsDictionary = [[TapTalk sharedInstance] getProjectConfigs];
NSString *usernameIgnoreCaseString = [projectConfigsDictionary objectForKey:@"usernameIgnoreCase"];
BOOL usernameIgnoreCase = [usernameIgnoreCaseString boolValue];
```

{% endtab %}
{% endtabs %}

### Custom Configs

Custom config values are specified by the user, and can be customized through the TapTalk.io Dashboard. To get the project's custom configs, call the **getCustomConfigs** method.

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

```csharp
#import <TapTalk/TapTalk.h>
  
NSDictionary *customConfigsDictionary = [[TapTalk sharedInstance] getCustomConfigs];
```

{% endtab %}
{% endtabs %}

### Refresh Remote Configs

To refresh remote configs with the latest updated values, call the **refreshRemoteConfigs** method in TapTalk.io class.

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

```csharp
#import <TapTalk/TapTalk.h>
  
[[TapTalk sharedInstance] refreshRemoteConfigs];
```

{% endtab %}
{% endtabs %}

### Enable / Disable Auto Contact Sync

If you are using UI implementation method in your application, TapTalk.io provides a feature to automatically sync your user's phone contacts with their TapTalk.io contacts. You can choose to enable or disable auto contact sync by calling these methods. If auto contact sync is enabled, TapTalk.io will automatically sync your user's phone contacts and add them to TapTalk.io contacts if their phone number is registered to TapTalk.io when the application is opened. Please note that the **default value** is **enabled**.

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

```csharp
#import <TapTalk/TapTalk.h>
  
// Enable or disabled auto contact sync
// Value is enabled by default if you do not set this method
[[TapTalk sharedInstance] setAutoContactSyncEnabled:IS_ENABLED];
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
**Parameter**\
`IS_ENABLED`: (BOOL) set to TRUE/YES to enable auto contact sync
{% endhint %}

### Get Auto Contact Sync Status

Use this method to obtain auto contact sync status. This method will return true if auto contact sync is enabled.

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

```csharp
#import <TapTalk/TapTalk.h>
  
BOOL isAutoContactSyncEnabled = [[TapTalk sharedInstance] isAutoContactSyncEnabled];
```

{% endtab %}
{% endtabs %}

### Obtain Current Navigation Controller in TapUI

To refresh remote configs with the latest updated values, call the **refreshRemoteConfigs** method in TapTalk.If you are using TapUI and want to integrate with your app, you can get the current active view controller or navigation controller by using the following codes.

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

```csharp
#import <TapTalk/TapUI.h>

// Get TapTalk.io current active view controller
UIViewController *activeViewController = [[TapUI sharedInstance] getCurrentTapTalkActiveViewController];

// Get TapTalk.io current active navigation controller
UINavigationController *activeNavigationController = [[TapUI sharedInstance] getCurrentTapTalkActiveNavigationController];
```

{% endtab %}
{% endtabs %}

### Set Image Compression Quality

You can customize the compression quality of images used for upload and download. The range of the compression quality is set between 0.1f and 1.0f. The higher the quality, the better the images will look, but they will also take more storage space as their size increases.

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

```csharp
#import <TapTalk/TapTalk.h>

[[TapTalk sharedInstance] setImageCompressionQuality:IMAGE_COMPRESSION_QUALITY];
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
**Parameters**\
\&#xNAN;**`IMAGE_COMPRESSION_QUALITY`**: (CGFloat) image compression quality between 0.1f to 1.0f
{% endhint %}

### Smart Local Cache Management

In order to optimize storage usage and performance, TapTalk.io cleans any local data of messages that are older than 1 month. This cleanup runs on a scheduled interval. Deleted messages can later be retrieved from the server when required.

### Encrypted Chat

TapTalk.io SDK encrypts all message contents before sending them to the server to protect any sensitive content contained in the messages. All messages received and stored in the server will stay encrypted. Messages will be decrypted once fetched in end user's local device in order to show their contents. TapTalk.io uses **AES Crypt** combined with secure local password to encrypt and decrypt message contents.
