# Remote Config

{% hint style="info" %}
This feature is supported in iOS SDK 2.11.0 and above.
{% endhint %}

Remote Config is a feature that lets you replace values or properties managed in your application with parameter values defined in the Hackle Dashboard, enabling real-time control of application behavior and settings.

Navigate to the Remote Config screen in the Hackle Dashboard to configure parameters and set values according to user identification rules.

## remoteConfig

Calling the `remoteConfig()` method returns a `HackleRemoteConfig` instance containing the Remote Config information (configured parameters and rule information) for the user.

{% tab title="Swift" %}

```swift
// 원격 구성 정보 담은 인스턴스를 반환합니다.
let remoteConfig = hackleApp.remoteConfig()
```

{% endtab %}

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

```objectivec
// 원격 구성 정보 담은 인스턴스를 반환합니다.
HackleRemoteConfig *remoteConfig = [hackleApp remoteConfig];
```

{% endtab %}
{% endtabs %}

## Query Remote Config Parameters

* The `HackleRemoteConfig` instance returned by `remoteConfig()` contains all the parameter configuration set in Remote Config.
* Since parameters set on the Hackle Remote Config screen exist as key-value pairs, you can use the methods below to retrieve parameter values according to the configured parameter type.
* You can dynamically change rules and values on the Remote Config parameter settings screen.

{% hint style="warning" %}
Remove Remote Config-related code after archiving.

Once a Remote Config parameter is archived, you can no longer access its parameter information. After archiving a Remote Config parameter, you must clean up the related code.

### getString

* Returns a parameter value configured as STRING or JSON type.
* Returns the default value or the value set by the rule based on the state decision.

{% tab title="Swift" %}

```swift
let remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig()

let strValue: String = remoteConfig.getString(forKey: "parameter_key_string_type", defaultValue: "defaultValue")
let jsonValue: String = remoteConfig.getString(forKey: "parameter_key_json_type", defaultValue: "defaultValue")
```

{% endtab %}

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

```objectivec
HackleRemoteConfig *remoteConfig = [[Hackle app] remoteConfig];

NSString *stringValue = [remoteConfig getStringForKey:@"string" defaultValue:@"defaultValue"];

NSString *jsonValue = [remoteConfig getStringForKey:@"parameter_key_json_type" defaultValue:@"defaultValue"];
```

{% endtab %}
{% endtabs %}

### getInt

* Returns a parameter value configured as Number type as an Int.
* Returns the default value or the value set by the rule based on the state decision.

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

```swift
let remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig()

let intValue: Int = remoteConfig.getInt(forKey: "parameter_key_number_type", defaultValue: 0)
```

{% endtab %}

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

```objectivec
HackleRemoteConfig *remoteConfig = [[Hackle app] remoteConfig];

int intValue = [remoteConfig getIntForKey:@"parameter_key_number_type" defaultValue:@0];
```

{% endtab %}
{% endtabs %}

### getDouble

* Returns a parameter value configured as Number type as a Double.
* Returns the default value or the value set by the rule based on the state decision.

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

```swift
let remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig()

let doubleValue: Double = remoteConfig.getDouble(forKey: "parameter_key_number_type", defaultValue: 0.0)
```

{% endtab %}

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

```objectivec
HackleRemoteConfig *remoteConfig = [[Hackle app] remoteConfig];

double doubleValue = [remoteConfig getDoubleForKey:@"parameter_key_number_type" defaultValue:0.0];
```

{% endtab %}
{% endtabs %}

### getBool

* Returns a parameter value configured as Boolean type.
* Returns the default value or the value set by the rule based on the state decision.

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

```swift
let remoteConfig: HackleRemoteConfig = hackleClient.remoteConfig()

let boolValue: Bool = remoteConfig.getBool(forKey: "parameter_key_boolean_type", defaultValue: false)
```

{% endtab %}

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

```objectivec
HackleRemoteConfig *remoteConfig = [[Hackle app] remoteConfig];

bool boolValue = [remoteConfig getBoolForKey:@"parameter_key_boolean_type" defaultValue:false];
```

{% endtab %}
{% endtabs %}
