Documentation
Official documentation can be found on the Mobile Buy SDK for iOS page.
API Documentation
API docs (.docset
) can be generated with the Documentation
scheme or viewed online at Cocoadocs: http://cocoadocs.org/docsets/Mobile-Buy-SDK/.
The SDK includes a pre-compiled .docset that can be used in API documentation browser apps such as Dash.
Installation
Dynamic Framework Installation
- Drag the
Mobile Buy SDK.xcodeproj
into your existing project - Add the
Buy
target as aTarget Dependancy
in theBuild Phases
of your project's target - Add the
Buy
(second target on the list is the Dynamic framework) target in theEmbedded Binaries
section inBuild Phases
See the Sample Apps for an example of Dynamic Framework usage.
Static Framework Installation
If you would like to not include the Mobile Buy SDK Project within your existing project, you can link directly to the Buy.framework
.
- Open the
Mobile Buy SDK.xcodeproj
and build theStatic Universal Framework
scheme - Drag the
Buy.framework
that was just created fromMobile Buy SDK Sample Apps
into theLinked Frameworks and Libraries
section for the target you want to add the framework to. Check Copy items if needed so the framework is copied to your project - In the
Build Settings
tab, add-all_load
toOther Linker Flags
CocoaPods
Add the following line to your podfile:
pod "Mobile-Buy-SDK"
Then run pod install
#import "Buy.h"
Carthage
Add the following line to your Cartfile
github "Shopify/mobile-buy-sdk-ios"
Then run carthage update
Quick Start
Import the module
@import Buy;
Initialize the BUYClient
with your credentials from the Mobile App Channel
BUYClient *client = [[BUYClient alloc] initWithShopDomain:@"yourshop.myshopify.com"
apiKey:@"aaaaaaaaaaaaaaaaaa"
appId:@"99999"];
Storefront API
After initializing the client with valid shop credentials, you can begin fetching collections.
[client getCollectionsPage:1 completion:^(NSArray<BUYCollection *> *collections, NSError *error) {
if (collections && !error) {
// Do something with collections
} else {
NSLog(@"Error fetching collections: %@", error.userInfo);
}
}];
Having a collection, we can then retrieve an array of products within that collection:
BUYCollection *collection = collections.firstObject;
[client getProductsPage:1 inCollection:collection.collectionId completion:^(NSArray<BUYProduct *> *products, NSUInteger page, BOOL reachedEnd, NSError *error) {
if (products && !error) {
// Do something with products
} else {
NSLog(@"Error fetching products in collection %@: %@", collection.collectionId, error.userInfo);
}
}];
Customer API
Customer Login
You can allow customers to login with their existing account using the SDK. First, we'll need to create the BUYAccountCredentials
object used to pass authentication credentials to the server.
NSArray *credentialItems = @[
[BUYAccountCredentialItem itemWithEmail:@"john.smith@gmail.com"],
[BUYAccountCredentialItem itemWithPassword:@"password"],
];
BUYAccountCredentials *credentials = [BUYAccountCredentials credentialsWithItems:credentialItems];
We can now use the credentials object to login the customer.
[client loginCustomerWithCredentials:credentials callback:^(BUYCustomer *customer, NSString *token, NSError *error) {
if (customer && token && !error) {
// Do something with customer and store token for future requests
} else {
NSLog(@"Failed to login customer: %@", error.userInfo);
}
}];
Customer Creation
Creating a customer account is very similar to login flow but requres a little more info in the credentials object.
NSArray *credentialItems = @[
[BUYAccountCredentialItem itemWithFirstName:@"John"],
[BUYAccountCredentialItem itemWithLastName:@"Smith"],
[BUYAccountCredentialItem itemWithEmail:@"john.smith@gmail.com"],
[BUYAccountCredentialItem itemWithPassword:@"password"]
];
BUYAccountCredentials *credentials = [BUYAccountCredentials credentialsWithItems:credentialItems];
After we obtain the customers first name, last name and password in addition to the email and password fields, we can create an account.
[client createCustomerWithCredentials:credentials callback:^(BUYCustomer *customer, NSString *token, NSError *error) {
if (customer && token && !error) {
// Do something with customer and store token for future requests
} else {
NSLog(@"Failed to create customer: %@", error.userInfo);
}
}];
Integration Guide
Consult the Usage Section of the Integration Guide on how to create a cart, checkout and more with the SDK.
Building the SDK
Clone this repo or download as .zip and open Mobile Buy SDK.xcodeproj
.
The workspace includes the Mobile Buy SDK project.
Mobile Buy SDK Targets and schemes
The Mobile Buy SDK includes a number of targets and schemes:
Buy: This is the Mobile Buy SDK dynamic framework. Please refer to the installation section above
Static Universal Framework: This builds a static framework from the
Buy
target using thebuild_universal.sh
script in theStatic Universal Framework
target and copies the built framework in the/Mobile Buy SDK Sample Apps
folder. This is a fat binary that includes arm and i386 slices. Build this target if you have made any changes to the framework that you want to test with the sample apps as the sample apps do not build the framework directly but embed the already built frameworkMobile Buy SDK Tests: Tests for the Mobile Buy SDK framework. See instructions below
Documentation: This generates appledoc documentation for the framework
Sample Apps
The repo includes 3 sample apps. Each sample apps embeds the dynamic framework and includes readme files with more information:
We suggest you take a look at the Advanced Sample App and test your shop with the sample app before you begin. If you run into any issues, the Advanced Sample App is also a great resource for debugging integration issues and checkout.
Product View
The Advanced Sample App includes an easy-to-use product view to make selling simple in any app. The ProductViewController
displays any product, it's images, price and details and includes a variant selection flow. It will even handle Apple Pay and web checkout automatically:
You can also theme the ProductViewController
to better match your app and products being displayed:
The Advanced Sample App includes a demo of the ProductViewController
. Documentation on how to use the ProductViewController
is also available here.
Unit Tests
To run the Mobile Buy SDK integration tests against an actual shop, you will need a Shopify shop that is publicly accessible (not password protected). Please note that the integration tests will create an order on that shop. This is to validate that the SDK works properly with Shopify. Modify the test_shop_data.json file to contain your shop's credentials and the required product IDs, gift cards, and discounts as necessary.
If the credentials in the test_shop_data.json are empty, running the integration tests will use mocked respoonses. The mocked responses are defined in mocked_responses.json. Do not check in credentials in this file.
Alternatively, you can edit the Mobile Buy SDK Tests
scheme and add the following arguments to the Environment Variables:
-
shop_domain
: Your shop's domain, for example:abetterlookingshop.myshopify.com
-
api_key
: The API provided when setting up the Mobile App channel on Shopify Admin: https://your_shop_id.myshopify.com/admin/mobile_app/integration -
app_id
: The App ID provided with the API Key above -
gift_card_code_11
,gift_card_code_25
,gift_card_code_50
: Three valid Gift Card codes for your shop -
expired_gift_card_code
: An expired Gift Card code -
expired_gift_card_id
: The ID for the expired Gift Card -
product_ids_comma_separated
: a comma seperated list of product IDs (2 is suitable) to use for the cart
