Caveat -- Deprecation

Pinterest considers this SDK deprecated. You can still build an integration with Pinterest into your iOS app using the RESTful endpoints directly. Best practice guidelines exist about use of OAuth within a mobile application. For instance, see RFC 8252.

For documentation on the API itself, visit the Pinterest Developers website.

PinterestSDK for iOS

The PinterestSDK for iOS will allow you to authenticate an account with Pinterest and make requests on behalf of the authenticated user. For details on the supported endpoint, visit the Pinterest API.

Installation

The PinterestSDK is a cocoapod. In order to use it you will need to create a Podfile if you do not already have one. Information on installing cocoapods and creating a Podfile can be found at Cocoapods.org. (Hint — to install cocoapods, run sudo gem install cocoapods from the command line; to create a Podfile, run pod init).

Open up the Podfile and add the following dependency:

pod "PinterestSDK", :git => "https://github.com/pinterest/ios-pdk.git"

Save your Podfile and run 'pod install' from the command line.

You can also just give the example app a try:

pod try https://github.com/pinterest/ios-pdk.git

Setting up your App

Registering Your App

Visit the Pinterest Developer Site and register your application. This will generate an appId for you which you will need in the next steps. Make sure to add your redirect URIs. For iOS your redirect URI will be pdk[your-appId]. For example, if you appId is 1234 your redirect URI will be pdk1234.

Configuring Xcode

The PinterestSDK will authenticate using OAuth either via the Pinterest app or, if the Pinterest app isn't installed, Safari. In order to redirect back to your app after authentication you will need set up a custom URL scheme. To do this, go to your app's plist and add a URL scheme named pdk[your-appId].

Configuring PDKClient

Before you make any calls using the PDKClient in your app, you will need to configure it with your appId:

[PDKClient configureSharedInstanceWithAppId:@"12345"];

The end of application:didFinishLaunchingWithOptions: seems like a reasonable place.

Authenticating

To authenticate a user, call authenticateWithPermissions:withSuccess:andFailure: on PDKClient. If the current auth token isn't valid or this is the first time you've requested a token, this call will cause an app switch to either the Pinterest app or Safari. To handle the switch back to your app, implement your app's application:openURL:sourceApplication:annotation: as follows:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
  return [[PDKClient sharedInstance] handleCallbackURL:url];
}

For iOS9 and latter application:openURL:sourceApplication:annotation: was deprecated, so you should implement application:openURL:options as follows:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options
{
  return [[PDKClient sharedInstance] handleCallbackURL:url];
}

Example App

A good place to start exploring the PDK is with the example app. To run it browse to the Example directory and run pod install. Next open PinterestSDK.xcworkspace in XCode and run it.
