App.net SDK in Objective-C
0.64.4
Snapper is designed to work on iOS 7.0 or higher, or Mac OS X Mavericks (10.9) or higher.
Snapper requires ARC, and should compile and test in Xcode 5.1 or higher.
Snapper makes use of the GitHub framework Mantle for its model objects. You will need to perform git submodule update --init --recursive to pull down Mantle and its dependencies.
Use of Snapper assumes familiarity with the App.net API and assumes that your app's configuration has all migrations enabled.
Snapper makes extensive use of blocks for progress and completion callbacks. All API calls are built upon NSOperation, to allow for asynchronous activity. No funny business is performed inside of these operations, so you can use them as you would any other NSOperation, including calling [op waitUntilFinished] if you need synchronous behavior. Snapper doesn't provide any specific operation queues, so you are free to queue up operations in whatever manner you see fit.
Almost all API calls require an access token of some sort. It is beyond the scope of this library to create or manage OAuth 2 access tokens, or to store them in a secure location, such as the iOS or Mac OS X keychain. However, Snapper uses an internal account store to retrieve access tokens when API calls are being constructed.
The first order of business when using Snapper is to store one or more access tokens. This is done like so:
SNPAccount* account = [[SNPAccountManager sharedAccountManager] createAccountWithName:@"The Pilgrim"
username:@"pilgrim"
userId:1199
accessToken:@"12345"
tokenType:@"Bearer"];
The returned account object includes a property, accountId, with a generated opaque ID for the account. You will use this ID for any operations which require the access token.
Note that this account manager is runtime-only. Account information is not persisted.
The following model objects are defined. Note that some of these objects are only used inside of other model objects. Operations that request an NSArray of objects expect objects of these types and not dictionaries.
Some notes are in order for a few of these model objects.
This is the object contained inside a Channel's readers or writers properties.
Represents Post, Message, or User annotations. Note that the value property is only a dictionary, to allow for the flexibility inherent in annotations.
This object represents the dictionary contained in User objects. Note that it does not contain an entities property with subordinate mentions, links, or hashtags array properties; those properties exist at the root of this object.
This is an abstract object that is inherited by the Mention, Link, and Hashtag objects. It will probably never be used directly, but provides a common base for those entities.
All operations provide their responses by way of blocks. With a few exceptions, the signature for these blocks contain one parameter: SNPResponse.
There are far too many operations defined in Snapper to list them here. Please browse the source code or headers to see which operations are available. Operations are named so that they correspond exactly or as close as possible to the resources documented in the official App.net API documents.
Responses are encapsulated in the SNPResponse object. Inside the response object is a data property (an id, because results can be an object, a dictionary, or an array of objects, depending on the endpoint), and a metadata property. The metadata property is an SNPMetadata object that contains some combination of error information, stream marker information, and/or pagination data.
When processing responses from an operation, examine the data property first: if it's nil, there is likely an error, and the various error properties in the SNPMetadata object will provide more details.
The SNPAPIUtils class provides some methods for constructing URLs to the various App.net API endpoints. You will almost never have to use these directly. However, this class provides a property that allows you to change the "API root" (i.e., https://alpha-api.app.net/stream/0) if the occasion arises (e.g., if App.net releases a "development environment", or you create a stubbed API server for testing).
Snapper includes unit tests for iOS and Mac OS X. Unit tests are provided for most functions. The notable exception is for the *Operation classes: since these require an OAuth 2 access token in order to function, creating unattended unit tests seems pointless. Insight into making this work without compromising security is greatly appreciated.
