A threadsafe, lightweight implementation of Promises in Objective-C.

Installation

I reccomend installation through CocoaPods, although you can use git submodules if you wish. pod 'DANPromise'

Usage

DANDeferredValue *deferred = [DANDeferredValue deferredValue];
DANPromise *promise = [deferred promise];

[promise then:^(id result) {
    NSLog(@"Completed with result: %@", result);
}];

[promise fullfill:@"Hello"];
