CreateSend Objective-C

CreateSend Objective-C is a library for talking to the Campaign Monitor API from Cocoa & Cocoa Touch applications. It supports iOS 5.0+ & Mac OS X 10.7+.

Features

• Implements the complete functionality of the API.
• Provides a drop-in UI for adding new subscribers to your lists, with custom field support.

Sample Project

A sample project is included in $SRCROOT/Example/CreateSendExample/CreateSendExample.xcodeproj. With the help of IBAForms by the friendly folks at Itty Bitty Apps, CreateSendExample demonstrates presenting a form for subscribing to a Campaign Monitor list.

You will need to specify your API key in CSExampleAppDelegate.m before building & running CreateSendExample.

The provided CSSubscriptionFormViewController class can present a simple form with name & email address, or it can display the custom fields configured for the subscription list. Set the customFieldBehavior variable in CSExampleAppDelegate.m to any of the values specified in CSExampleAppCustomFieldBehavior to configure the form in fixed-fields or dynamic-fields mode.

Basic API Wrapper Usage Examples

If you prefer to build your own custom UI, you can simply use the API wrapper directly. For full documentation of the API wrapper, see the class documentation is available in Documentation/html/index.html (generated with rake docs:generate).

Here's a some examples to get you started.

Authenticating using OAuth 2

The Campaign Monitor API supports authenticating using either OAuth 2 or an API key over basic authentication. Using OAuth 2 is recommended. For full details see the API documentation.

Here's the recommended approach for authenticating using OAuth 2 from this library.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    API = [[CSAPI alloc] initWithClientID:@"CLIENT_ID" clientSecret:@"CLIENT_SECRET" scope:@[CSAPIClientScopeManageLists, CSAPIClientScopeImportSubscribers]];
    if (!API.isAuthorized) {
        [API authorize];    
    }
}

Once authorized, your app will be launched with the URL scheme csapiCLIENT_ID. The easiest way to register for this scheme is right-click on your app's plist file and select Open As → Source Code, and add the following code below the first <dict> tag, substituting CLIENT_ID with your app's client id:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>csapiCLIENT_ID</string>
        </array>
    </dict>
</array>

Now that your app is registered for the correct scheme, you need to add the following code to your application delegate in order to complete the authorization flow:

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    if ([API handleOpenURL:url]) {
        if (API.isAuthorized) {
            NSLog(@"App has been authorized successfully!");
            // At this point you can start making API calls
        }
        return YES;
    }
    // Add whatever other url handling code your app requires here
    return NO;
}

Getting an API key

As an alternative to using OAuth 2 for authentication, you can also use an API key.

Here's how you get an API key using this library.

CSAPI *API = [[CSAPI alloc] init];

[API getAPIKeyWithSiteURL:@"http://yoursite.createsend.com/" username:@"yourusername" password:@"yourpassword" completionHandler:^(NSString *APIKey) {
    NSLog(@"Your API key is %@", APIKey);
} errorHandler:^(NSError *error) {
    NSLog(@"Something went wrong: %@", error);
}];

Subscribing to a list

Here's an example of how to subscribe to a list (authenticating with API key rather than OAuth).

CSAPI *API = [[CSAPI alloc] initWithAPIKey:@"ab6b0598d32fecd63485b18abb4f0ad7"];

NSArray *customFields = @[
    [CSCustomField customFieldWithKey:@"AddressStreet" value:@"1 Infinite Loop"],
    [CSCustomField customFieldWithKey:@"AddressSuburb" value:@"Cupertino"]
];

[API subscribeToListWithID:@"66f889ae2e1981157285b4f76f2e02ad"
              emailAddress:@"[email protected]"
                      name:@"Johnny Appleseed"
         shouldResubscribe:YES
              customFields:customFields
         completionHandler:^(NSString *subscribedAddress) {
            NSLog(@"Successfully subscribed %@", subscribedAddress);
         } errorHandler:^(NSError *error) {
            NSLog(@"Something went wrong: %@", error);
         }];
