How to implement ChimpKit3? - objective-c

Question

I'm having big difficulties following the example in the ChimpKit readme on github.
NSDictionary *params = #{#"id": #"8ce4588803", #"email": #{#"email": #"foo#example.com"}, #"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
});
}
}
}
}];
Apparently this is the code to subscribe an email to a list in MailChimp
I am getting errors:
/SubscribeEmailViewController.m:146:105: Expected ')'
SubscribeEmailViewController.m:146:103: Type specifier missing,
defaults to 'int'
SubscribebeEmailViewController.m:147:44: Use of undeclared identifier
'request'
SubscribeEmailViewController.m:146:103: Incompatible block pointer
types sending 'int ((^)(void))' to parameter of type
'ChimpKitRequestCompletionBlock' (aka 'void (^)(NSURLResponse
*__strong, NSData *__strong, NSError *__strong)')
This is basically copy and paste from the example, I can't figure out what detail I'm missing here.
ChimpKit was installed via cocoapods
