VIMNetworking

VIMNetworking is an Objective-C library that enables interaction with the Vimeo API. It handles authentication, request submission, and request cancellation. Advanced features include caching and powerful model object parsing.

If you'd like to upload videos check out VimeoUpload.

Setup

CocoaPods

d this to your podfile
et 'YourTarget' do
pod 'VIMNetworking', '{CURRENT_POD_VERSION}'

Note that VIMNetworking has dependencies on AFNetworking and VIMObjectMapper. They will be imported as pods.

Git Submodules

Add VIMNetworking, VIMObjectMapper and AFNetworking (Release 2.5.4) as submodules of your git repository.

submodule add git@github.com:vimeo/VIMNetworking.git
submodule add git@github.com:vimeo/VIMObjectMapper.git
submodule add git@github.com:AFNetworking/AFNetworking.git

Add each submodule's classes to your project / target.

If you're also including VIMUpload in your project / target, note that both VIMUpload and VIMNetworking include the Certificate/digicert-sha2.cer file (this file is used for cert pinning). You'll have to remove one of the digicert-sha2.cer files from your target to avoid a “Multiple build commands for output file…” warning.

Initialization

On app launch, configure VIMSession with your client key, secret, and scope strings. And once initialization is complete, authenticate if necessary.

ort "VIMNetworking.h"

.

OOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 

VIMSessionConfiguration *config = [[VIMSessionConfiguration alloc] init];
config.clientKey = @"your_client_key";
config.clientSecret = @"your_client_secret";
config.scope = @"your_scope"; // E.g. "private public upload etc"
config.keychainService = @"your_service"; 
config.keychainAccessGroup = @"your_access_group"; // Optional

[VIMSession sharedSession setupWithConfiguration:config];    

if ([[VIMSession sharedSession].account isAuthenticated] == NO)
{
    NSLog(@"Authenticate...");
}
else
{
    NSLog(@"Already authenticated!");
}

. . .

Note that you must specify a value for keychainService and can optionally provide a value for keychainAccessGroup. The role of the latter value is detailed here in the section on Keychain Access Groups.

Authentication

All calls to the Vimeo API must be authenticated. This means that before making requests to the API you must authenticate and obtain an access token. Two authentication methods are provided:

1. Client credentials grant: This mechanism allows your application to access publicly accessible content on Vimeo.

2. OAuth authorization code grant: This mechanism allows a Vimeo user to grant permission to your app so that it can access private, user-specific content on their behalf.

Client Credentials Grant

MSession sharedSession] authenticateWithClientCredentialsGrant:^(NSError *error) {

    if (error == nil)
    {
        NSLog(@"Success!");
    }
    else
    {
        NSLog(@"Failure: %@", error);
    }

OAuth Authorization Code Grant

1. Set up a redirect url scheme:

Navigate to your app target settings > Info > URL Types. Add a new URL Type, and under url scheme enter vimeo{CLIENT_KEY} (ex: if your CLIENT_KEY is 1234, enter vimeo1234). This allows Vimeo to redirect back into your app after authorization.

You also need to add this redirect URL to your app on the Vimeo API site. Under ?App Callback URL?, add vimeo{CLIENT_KEY}://auth (for the example above, vimeo1234://auth).

1. Open the authorization URL in Mobile Safari:

L *URL = [[VIMSession sharedSession].authenticator codeGrantAuthorizationURL];
Application sharedApplication] openURL:URL];

1. Mobile Safari will open and the user will be presented with a webpage asking them to grant access based on the scope that you specified in your VIMSessionConfiguration above.
   

2. The user is then redirected back to your application. In your AppDelegate?s URL handling method, pass the URL back to VIMAPIClient to complete the authorization grant:

OOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation

[[VIMSession sharedSession] authenticateWithCodeGrantResponseURL:url completionBlock:^(NSError *error) {

    if (error == nil)
    {
        NSLog(@"Success!");
    }
    else
    {
        NSLog(@"Failure: %@", error);
    }

}];

return YES;

Requests

With VIMNetworking configured and authenticated, you?re ready to start making requests to the Vimeo API.

JSON Request

MSession sharedSession].client requestURI:@"/videos/77091919" completionBlock:^(VIMServerResponse *response, NSError *error) {

id JSONObject = response.result;
NSLog(@"JSONObject: %@", JSONObject);

Model Object Request

equestDescriptor *descriptor = [[VIMRequestDescriptor alloc] init];
riptor.urlPath = @"/videos/77091919";
riptor.modelClass = [VIMVideo class];

MSession sharedSession].client requestDescriptor:descriptor completionBlock:^(VIMServerResponse *response, NSError *error) {

VIMVideo *video = (VIMVideo *)response.result;
NSLog(@"VIMVideo object: %@", video);

Collection Request

equestDescriptor *descriptor = [[VIMRequestDescriptor alloc] init];
riptor.urlPath = @"/me/videos";
riptor.modelClass = [VIMVideo class];
riptor.modelKeyPath = @"data";

MSession sharedSession].client requestDescriptor:descriptor completionBlock:^(VIMServerResponse *response, NSError *error) {

NSArray *videos = (NSArray *)response.result; 
NSLog(@"Array of VIMVideo objects: %@", videos);

Caching Behavior

equestDescriptor *descriptor = [[VIMRequestDescriptor alloc] init];
riptor.urlPath = @"/videos/77091919";
riptor.modelClass = [VIMVideo class];
riptor.cachePolicy = VIMCachePolicy_NetworkOnly; // Or VIMCachePolicy_LocalOnly etc.
riptor.shouldCacheResponse = NO; // Defaults to YES



ee VIMRequestDescriptor.h/m additional request configuration options

Request Cancellation

IMRequestToken> currentRequest = [[VIMSession sharedSession].client requestURI:@"/videos/77091919" completionBlock:^(VIMServerResponse *response, NSError *error) {

id JSONObject = response.result;
NSLog(@"JSONObject: %@", JSONObject);



MSession sharedSession].client cancelRequest:currentRequest];

r

MSession sharedSession].client cancelAllRequests];

Lightweight Use

If you want to use your own OAuth token you can circumvent VIMSession and its authentication mechanisms and make requests like so:

lient *client = [[VIMClient alloc] initWithDefaultBaseURL];
nt.requestSerializer = ...

here client.requestSerializer is an AFJSONRequestSerializer subclass that sets the following information for each request:
serializer setValue:@"application/vnd.vimeo.*+json; version=3.2" forHTTPHeaderField:@"Accept"];
serializer setValue:@"Bearer your_oauth_token" forHTTPHeaderField:@"Authorization"];

ent requestURI:@"/videos/77091919" completionBlock:^(VIMServerResponse *response, NSError *error)


id JSONObject = response.result;
NSLog(@"JSONObject: %@", JSONObject);

Caching

If you'd like to turn on caching for this lighter weight use case:

lient *client = [[VIMClient alloc] initWithDefaultBaseURL];
nt.cache = VIMCache *cache = [VIMCache sharedCache];
r client.cache = VIMCache *cache = [[VIMCache alloc] initWithName:@"your_cache_name"];

VIMObjectMapper

VIMObjectMapper converts JSON into model objects. If you'd like to use it on its own (by including the raw source in your project, or by including the ObjectMapper subspec, follow the steps below.

Subclass VIMModelObject

Make your custom model object a subclass of VIMModelObject and optionally implement the VIMMappable protocol methods:

ort "VIMModelObject.h"

ss VIMPictureCollection;

erface VIMUser : VIMModelObject

perty (nonatomic, copy) NSString *name;
perty (nonatomic, strong) VIMPictureCollection *pictureCollection;
perty (nonatomic, strong) NSDictionary *uploadQuota;
perty (nonatomic, strong) NSArray *websites;

ort "VIMUser.h"
ort "VIMPictureCollection.h"
ort "VIMObjectMapper.h"

lementation VIMUser

gma mark - VIMMappable // All methods are optional, implement to specify how the object should be "inflated"

SDictionary *)getObjectMapping

rn @{@"pictures": @"pictureCollection"};


lass)getClassForCollectionKey:(NSString *)key

[key isEqualToString:@"uploadQuota"])

rn [NSDictionary class];


[key isEqualToString:@"websites"])

rn [NSArray class];


rn nil;


lass)getClassForObjectKey:(NSString *)key

[key isEqualToString:@"pictures"])

rn [VIMPictureCollection class];


rn nil;


oid)didFinishMapping

o any post-parsing work you might want to do

Get some JSON

 = {
 = "Homer Simpson";
ures = {
= "...";
s = (...);

oad_quota" = { ... };
ites = ( ... );

Let VIMObjectMapper go to work

ctionary *JSON = ...;

bjectMapper *mapper = [[VIMObjectMapper alloc] init];

per addMappingClass:[VIMUser class] forKeypath:@"user"];

ser *user = [mapper applyMappingToJSON:JSON];
