Deferred

Introduction

A little Functional & Reactive programming library.

Installation

Cocoapods

Add TanDeferred in your Podfile:

use_frameworks!

pod "TanDeferred"

Then run the following command:

$ pod install

Manually

1. Download the source code.
2. Drag folder Deferred/Deferred into your project.

Usage

Basic usage

// Create an instance of Deferred
Deferred *deferred = [Deferred deferred];

// Subscribe
[deferred subscribe:^(id  _Nullable value) {
    NSLog(@"%@", value);
}];

// Just fill it
[deferred fill:@"Hello World"];

Or you can create with an initialized value:

Deferred *deferred = [Deferred just:@"Hello World"];

Map & FlatMap

[[[deferred map:^id _Nullable(id  _Nullable value) {
    return [value stringByAppendingString:@"Good morning"];
}] flatMap:^Deferred * _Nonnull(id  _Nullable value) {
    return [Deferred just:[value stringByAppendingString:@"Good night"]];
}] subscribe:^(id  _Nullable value) {
    NSLog(@"%@", value);
}];

Multi-thread

There are four queues to control Deferred to execute missions with multi-thread:

• MainQueue
• SyncQueue （Default）
• AsyncQueue
• CustomQueue

[[deferred mapOn:[AsyncQueue shared] with:^id _Nullable(id  _Nullable value) {
    return [value stringByAppendingString:@"Baby"];
}] subscribeOn:[MainQueue shared] with:^(id  _Nullable value) {
    NSLog(@"%@", value);
}];
