Fast Integration with Smart Life App SDK for iOS

This topic describes how to use CocoaPods to quickly integrate Tuya Smart Life App SDK for iOS into your project. The SDK requires iOS 9.0 or later.

SDK versions

• If you have integrated Smart Life App SDK versions earlier than v5.x.x into your project, follow the instructions in Upgrade Guide and upgrade to the latest version.
• If you have integrated legacy SDK versions into your project, after you upgrade to v5.0, delete the legacy security image file t_s.bmp from your project, and get the app key information for v5.0 from the Tuya IoT Development Platform.
• Starting from Smart Life App SDK for Android v4.0.0, the SDK is classified into the development edition and official edition. For more information, see Pricing. The development edition is suitable for personal non-commercial scenarios only. Do not use it for commercial purposes. If your app is planned to be launched on app stores or in other commercial scenarios, go to the Tuya IoT Development Platform and purchase the official edition. After the official edition is purchased:
  1. Rebuild the SDK and download the package of the official edition on the platform.
  2. Integrate the SDK of the official edition into your project.

Integrate with the SDK

Build and download the SDK

1. Log in to the Tuya IoT Development Platform.

2. Select the required SDKs or UI BizBundles of v5.x.x.

   If a legacy SDK version has been used, you can click the button in the top right corner to switch between the legacy and new versions.

   

3. Select the required SDKs or BizBundles and build your SDK.

   

4. After the build is finished, download the SDK to be integrated.

   

5. Extract ios_core_sdk.tar.gz and get the following important files:

   • Build: stores the security SDK exclusive to your app. This file is as important as the app key information. Keep the file properly and do not disclose the information in it.
   • ThingSmartCryption.podspec: used to reference and integrate with App SDK v5.0.

6. We recommend that you store both files at a sibling directory as podfile, so they can be referenced easily during subsequent development.

Use CocoaPods for fast integration

1. Update CocoaPods to the latest version. For more information about CocoaPods, see CocoaPods Guides.

2. Add the following code block to the Podfile:

   source 'https://github.com/tuya/tuya-pod-specs.git'
   platform :ios, '11.0'
   
   target 'Your_Project_Name' do
       # Build and get ThingSmartCryption from the Tuya IoT Development Platform (iot.tuya.com).
       # After the official edition is purchased, rebuild the SDK on the Tuya IoT Development Platform and integrate it into your project.
       # The dot slash (./) notation represents that the files that are obtained after ios_core_sdk.tar.gz is extracted are put at a sibling directory as podfile.
       # To use another directory, change the path to your desired directory.
       pod "ThingSmartCryption", :path =>'./'
       pod "ThingSmartHomeKit"
   end
   
   target 'Your_Extension_Target_Name' do
       # Regarding all extension targets, as long as ThingSmartHomeKit is imported, ThingSmartCryption must be imported too.
       pod "ThingSmartCryption", :path =>'./'
       pod "ThingSmartHomeKit"
   end
   

3. If your app contains extension targets, such as Siri and Widgets, make sure the Podfile is configured correctly.

4. In the root directory of your project, run pod update.

Initialize the SDK

1. Choose Target > General to open the project settings, and modify Bundle Identifier to the iOS Bundle ID of the app that is registered on the Tuya IoT Development Platform.

2. Add the following content to the PrefixHeader.pch file:

   #import <ThingSmartHomeKit/ThingSmartKit.h>
   

   Add the following content to the bridging header file xxx_Bridging-Header.h for a Swift project:

   #import <ThingSmartHomeKit/ThingSmartKit.h>
   

3. Open the AppDelegate.m file and initialize the SDK in [AppDelegate application:didFinishLaunchingWithOptions:].

Configure the SDK

- (void)startWithAppKey:(NSString *)appKey secretKey:(NSString *)secretKey;

Parameters

Sample code

Objective-C:

[[ThingSmartSDK sharedInstance] startWithAppKey:<#your_app_key#> secretKey:<#your_secret_key#>];

Swift:

ThingSmartSDK.sharedInstance()?.start(withAppKey: <#your_app_key#>, secretKey: <#your_secret_key#>)

Now, you are ready for app development.

Enable the debug mode

During the development, you can enable the debug mode and print logs for troubleshooting.

Objective-C:

#ifdef DEBUG
    [[ThingSmartSDK sharedInstance] setDebugMode:YES];
#else
#endif

Swift:

#if DEBUG
   ThingSmartSDK.sharedInstance()?.debugMode = true
#else
#endif

Configure multilingual options

The returned error messages and other UI text are displayed in languages as configured in the multilingual settings of your project and users’ mobile phone system languages. To support a certain language, add it to Localization of your project.

In the following example, a demo app is used to describe the process of app development with the App SDK. Before the development of your app, we recommend that you run the demo app.

Create a widget

Perform the following steps:

1. Modify the Podfile.

   target 'Your_Extension_Target_Name' do
       # 1. Regarding all extension targets, as long as ThingSmartHomeKit is imported, ThingSmartCryption must be imported too.
       # 2. Build and get ThingSmartCryption from the Tuya IoT Development Platform (iot.tuya.com).
       # After the official edition is purchased, rebuild the SDK on the Tuya IoT Development Platform and integrate it into your project.
       # The dot slash (./) notation represents that the files that are obtained after ios_core_sdk.tar.gz is extracted are put at a sibling directory as podfile.
       # To use another directory, change the path to your desired directory.
       pod "ThingSmartCryption", :path =>'./'
       pod "ThingSmartHomeKit"
   end
   
   post_install do | installer |
        installer.pods_project.targets.each do | target |
           target.build_configurations.each do | config |
               config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'
           end
       end
   end
   

   • Configure Target and import components or SDKs into Target as needed.
   • Note that ThingSmartCryption must be imported together with the SDK.

2. Configure AppGroups.

   • Grant permissions on AppGroups.
   • Before the SDK is initialized, set the App Groups Name for the SDK.
   • Only paid developer accounts can be granted permissions on AppGroups. Therefore, free developer accounts cannot be used to debug widget applications.

3. Configure the AppKey and AppSecret to initialize the SDK.

4. Before the SDK is initialized with AppKey, set the App Groups Name.

   [ThingSmartSDK sharedInstance].appGroupId = APP_GROUP_NAME;
   [[ThingSmartSDK sharedInstance] startWithAppKey:SDK_APPKEY secretKey:SDK_APPSECRET];
   

Demo app

Prepare the demo

In the Preparation topic, get the AppKey and AppSecret for iOS.

Make sure that BundleId, AppKey, and AppSecret are consistent with those used on the Tuya IoT Development Platform. Any mismatch will cause the SDK development app to fail.

Demo features

The demo app is coded in Swift and Objective-C. You can get the sample in Swift and sample in Objective-C on GitHub. The following features are supported:

• User registration and login

• User management

• Home management

• Wi-Fi Easy Connect (EZ) mode and access point (AP) mode

• Device Control

  

FAQs

SING_VALIDATE_FALED

• Problem: When an API request is made, an error message is returned in the following response:

  {
    "success" : false,
    "errorCode" : "SING_VALIDATE_FALED",
    "status" : "error",
    "errorMsg" : "Permission Verification Failed",
    "t" : 1583208740059
  }
  

• Solution: Make sure that BundleId, AppKey, and AppSecret are consistent with those used on the Tuya IoT Development Platform. Any mismatch will cause the authentication to fail. For more information, see Preparation.

• Note: After you purchase the official edition, rebuild the SDK and replace the key information with the new one on the Tuya IoT Development Platform.
