ChimpKit 3.1.1

ChimpKit is an API wrapper for the MailChimp API 2.0.

Requirements

A MailChimp account and API key. You can see your API keys here.

ChimpKit includes uses ARC. If your project doesn't use ARC, you can enable it per file using the -fobjc-arc compiler flag under "Build Phases" and "Compile Sources" on your project's target in Xcode.

Installation

There are two ways to add ChimpKit to your project:

Or using Git submodules. Add ChimpKit as a submodule of your git repository by doing something like:

cd myrepo
git submodule add https://github.com/mailchimp/ChimpKit3.git Libs/ChimpKit

Now add ChimpKit to your project by dragging the everything in the ChimpKit3 directory into your project.

Usage

First, set an API key:

[[ChimpKit sharedKit] setApiKey:apiKey];

You can now make requests. For example, here's how to subscribe an email address:

Using a block:

NSDictionary *params = @{@"id": listId, @"email": @{@"email": @"[email protected]"}, @"merge_vars": @{@"FNAME": @"Freddie", @"LName":@"von Chimpenheimer"}};
[[ChimpKit sharedKit] callApiMethod:@"lists/subscribe" withParams:params andCompletionHandler:^(ChimpKitRequest *request, NSError *error) {
    NSLog(@"HTTP Status Code: %d", request.response.statusCode);
    NSLog(@"Response String: %@", request.responseString);

    if (error) {
       //Handle connection error
        NSLog(@"Error, %@", error);
        dispatch_async(dispatch_get_main_queue(), ^{
            //Update UI here
        });
    } else {
        NSError *parseError = nil;
        id response = [NSJSONSerialization JSONObjectWithData:request.responseData
                                                      options:0
                                                        error:&parseError];
        if ([response isKindOfClass:[NSDictionary class]]) {
            id email = [response objectForKey:@"email"];
            if ([email isKindOfClass:[NSString class]]) {
                //Successfully subscribed email address
                dispatch_async(dispatch_get_main_queue(), ^{
                    //Update UI here
                });
            }
        }
    }
}];

Using the delegate pattern:

NSDictionary *params = @{@"id": listId, @"email": @{@"email": @"[email protected]"}, @"merge_vars": @{@"FNAME": @"Freddie", @"LName":@"von Chimpenheimer"}};
[[ChimpKit sharedKit] callApiMethod:@"lists/subscribe" withParams:params andDelegate:self];

And implement the ChimpKitRequestDelegate protocol:

- (void)ckRequestSucceeded:(ChimpKitRequest *)aRequest {
    NSLog(@"HTTP Status Code: %d", aRequest.response.statusCode);
    NSLog(@"Response String: %@", aRequest.responseString);

    NSError *parseError = nil;
    id response = [NSJSONSerialization JSONObjectWithData:request.responseData
                                                  options:0
                                                    error:&parseError];
    if ([response isKindOfClass:[NSDictionary class]]) {
        id email = [response objectForKey:@"email"];
        if ([email isKindOfClass:[NSString class]]) {
            //Successfully subscribed email address
            dispatch_async(dispatch_get_main_queue(), ^{
                //Update UI here
            });
        }
    }
}

- (void)ckRequestFailed:(ChimpKitRequest *)aRequest andError:(NSError *)anError {
    //Handle connection error
    NSLog(@"Error, %@", anError);
    dispatch_async(dispatch_get_main_queue(), ^{
        //Update UI here
    });
}

Calling other API endpoints works similarly. Read the API documentation for details.

Blocks and delegate methods can be called from a background queue

The examples above use dispatch_async to call back onto the main queue after parsing the response. If you've set shouldUseBackgroundThread to YES then ChimpKit will call your block from a background queue so you can parse the JSON response with low impact on interface responsiveness. You should dispatch_* back to the main queue before updating your UI as shown above. You can enable this behavior like so:

[[ChimpKit sharedKit] setShouldUseBackgroundThread:YES];

Controlling Timeout

ChimpKit defaults to a 10 second timeout. You can change that (globally) to 30 seconds like so:

[[ChimpKit sharedKit] setTimeoutInterval:30.0f];

MailChimp now supports OAuth2 and so does ChimpKit:

An example of logging in via OAuth is provided in the sample application. See ViewController.m.
