SDL iOS SDK Sample App

This is a guide that helps you get started with the SDL iOS SDK so that you can add Translation capabilities to your iOS app. This guide includes a short tutorial of a sample app that makes use of the SDK.

Adding the SDK to your app in 3 Easy Steps

STEP 1. Get Your SDL Language Cloud API Key

• [Sign Up Here] (https://languagecloud.sdl.com/translation-api/sign-up) to get a Free API Key

STEP 2. Install the SDK

• The SDK is available as a cocoapod and can be installed as follows:

platform :ios, '7.0'
pod "SDL-iOS-SDK", "~> 0.1.0"

STEP 3. Import the SDK in your code

#import "SDL.h"

Using the SDL Translation API

Setup your API Key once

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   [[SDL languageCloud] setup:@"<your api key>"]
   ...
}

Performing a text translation

 [[SDL languageCloud] translateText:@"Good Morning" from:[NSLocale localeWithLocaleIdentifier:@"en"] to:[NSLocale localeWithLocaleIdentifier:@"fr"] success:^(NSString* translation)
    {
        NSLog(@"Successful Translation: %@", translation);
    }
    failure:^(NSString* errorMessage)
    {
        NSLog(@"Error: %@", errorMessage);
    }
];

Sample App Tutorial

Download and open the project

• [Download the project] (https://github.com/dancali/sdl-ios-sampleapp/archive/master.zip) as a ZIP file
• Open the SDL-iOS-SampleApp.xcworkspace XCode Workspace file
• You should now see the project loaded in XCode:

Setup your API key

• If you run the project you should immediately get an error:

- Remove error line: ```ruby #error @"Setup your SDL Language Cloud API Key" ``` - And enter your valid API key: ```ruby [[SDL languageCloud] setup:@""]; ``` - Then run the project again - Everything should build perfectly and the simulator should launch

Perform a translation

• The app is pretty simple
• All it does is ask the user for input in English and it will translate the input the French
• The first thing you will see when running the app is a popup that will ask you for input:

- If you type something and press the Translate button, the app will perform the translation and popup the result:

- That's all there is to it

Under The Hood

• The translation call happens in the performTranslation method in SDLSampleApp.com
• If you look closely, it's one single asynchronous call:

- (void) performTranslation: (NSString*) text
{
    //Show some progress
    [_spinner startAnimating];
    
    [[SDL languageCloud] translateText:text from:[NSLocale localeWithLocaleIdentifier:@"en"] to:[NSLocale localeWithLocaleIdentifier:@"fr"] success:^(NSString* translation)
     {
         //Stop the progress first
         [_spinner stopAnimating];

         //Great, we got something, let's show it
         [self showTranslation:translation];
     }
     failure:^(NSString* errorMessage)
     {
         //Stop the progress first
         [_spinner stopAnimating];

         //Something went wrong, let's show the user what happened
         [self showTranslation:[NSString stringWithFormat:@"Error: %@", errorMessage]];
     }];
}

• Aside from the progress handling, the call is simple and straight-forward
• It passes in the text input we collected from the user and it specifies the language pair
• The from/to languages are specified as native NSLocale's
• And finally, the success block returns the translation and the failure block comes back with an error if something went wrong
