小编Fra*_*hou的帖子

在obj-c中,我可以使用这个方法:

RACSignal *signUpActiveSignal = [RACSignal combineLatest:@[validUsernameSignal, validPasswordSignal]
                reduce:^id(NSNumber*usernameValid, NSNumber *passwordValid){
                  return @([usernameValid boolValue]&&[passwordValid boolValue]);
                }];

当我把它翻译成swift时,像这样:

RACSignal.combineLatest([accountSignal, passwordSignal]) { () -> AnyObject! in
        // arguments
        return true
        }.subscribeNext { (reduceResult: AnyObject!) -> Void in
        KMLog("\(reduceResult)")
    }

我怎样才能获得参数
