Installation

CocoaPods

To integrate LingoHub into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'LingoHub'

Carthage

To integrate LingoHub into your Xcode project using Carthage, specify it in your Cartfile:

binary "https://raw.githubusercontent.com/lingohub/lh-ios-sdk/master/LingoHub.json"

Manually

If you prefer not to integrate LingoHub manually instead of using a Dependency Manager, download the latest LingoHub.xcframwork and add it to your project.

Usage

Import

Wherever you want to use LingoHub, import the module first

Swift

import LingoHub

Objective-C

#import <LingoHub/LingoHub.h>

Configuration

Configure the LingoHub SDK in your AppDelegate with:

• API Key
• Project Id
• optional: App Version (The default is the CFBundleShortVersionString of the main Bundle)

The easiest way is to use our Swizzle feature, so you can use NSLocalizedString as usual.

Swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    LingoHubSDK.shared.configure(withApiKey: "YOUR-API-KEY", projectId: "YOUR-PROJECT-ID")
    LingoHubSDK.shared.swizzleMainBundle()
}

Objective-C

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    [LingoHubSDK.shared configureWithApiKey:@"YOUR-API-KEY" projectId:@"YOUR-PROJECT-KEY"];
    [LingoHubSDK.shared swizzleMainBundle];
}

Check for updates

In order to have your localizations updated, include following code in your AppDelegate:

Swift

func applicationDidBecomeActive(_ application: UIApplication) {
    LingoHubSDK.shared.update { result in
        switch result {
        case .success(let value):
            print("Content updated: \(value)")
        case .failure(let error):
            print(error.localizedDescription)
        }
    }
}

Objective-C

- (void)applicationDidBecomeActive:(UIApplication *)application {
    [LingoHubSDK.shared updateWithCompletion:^(BOOL value, NSError * _Nullable error) {
        if (error != nil) {
            NSLog(@"Content updated: %d", value);
        } else {
            NSLog(error.localizedDescription);
        }
    }];
}

Manual usage

If you do not want to use method swizzling, you can get your updated localization by asking the LingoHub SDK for it.

Swift

func localizedString(withKey key: String, tableName: String? = nil) {
    if let localizedString = LingoHubSDK.shared.localizedString(forKey: key, tableName: tableName) {
        return localizedString
    }
    return NSLocalizedString(key, tableName: tableName, comment: "")
}

Objective-C

- (NSString * _Nonnull)localizedStringWithKey:(NSString * _Nonnull)key tableName:(NSString * _Nullable)tableName {
    NSString *updatedLocalization = [LingoHubSDK.shared localizedStringForKey:key tableName:tableName];
    if (updatedLocalization != nil) {
        return updatedLocalization;
    }

    return NSLocalizedStringFromTable(key, tableName, @"");
}

Observing updates

If LingoHub has found updated localization, it will post the LingoHubDidUpdateLocalization notification. Observe it to get notified on updates.

Swift

NotificationCenter.default.addObserver(forName: .LingoHubDidUpdateLocalization, object: nil, queue: nil) { [weak self] _ in
    self?.updateLocalization()
}

Objective-C

_weak MyViewController *weakSelf = self;
[NSNotificationCenter.defaultCenter addObserverForName:NSNotification.LingoHubDidUpdateLocalization object:nil queue:nil usingBlock:^(NSNotification * _Nonnull note) {
    MyViewController *strongSelf = weakSelf;
    [strongSelf updateLocalization];
}];

Language switching

If you would like to change the language of your app at runtime, you can use the LingoHub SDK for it.

Swift

LingoHubSDK.shared.setLanguage("de")

Objective-C

[LingoHubSDK.shared setLanguage:@"de"];

Preproduction mode

If you would like to test your localizations before submitting a new package, enable preproduction mode.

Swift

LingoHubSDK.shared.isPreproductionEnabled = true

Objective-C

[LingoHubSDK.shared setIsPreproductionEnabled:true];

Storyboard & XIB Localization

If you are using storyboard and/or XIB localization, you have to reload the view after LingoHub did update your localizations.
