MMX-PromiseKit

#Installation

Include the PromiseKit category with #import "MMX+PromiseKit.h".

#Usage

Most methods are a straightforward conversion from callbacks to promises. For example, to find channels with tag foo:

  [MMXChannel findByTags:[NSSet setWithArray:@[@"foo"]]]
  .then(^(NSNumber *count, NSArray* channels){
  });

For message methods that return a messageID before executing the callback, a promise is returned with the messageID as the first argument, and the completion promise as the second:

  MMXMessage *messsage = [MMXMessage messageToChannel:someChannel messageContent:someContent];
  [message send]
  .then(^(NSString *messageID, PMKPromise *complete){
    //Do something with messageID
    return complete;
  })
  .then(^(){
    //Message is now sent
  });
