<blockquote>
5+
<p>CocoaPods: The best way to manage library dependencies in Objective-C projects.</p></p>
6+
</blockquote>
7+
<p>If you&#39;re familiar with Ruby on Rails, it&#39;s the same thing as <a href="http://gembundler.com/">Bundler</a>, or it&#39;s lame copy attempt for Symfony 2, <a href="http://getcomposer.org/">Composer</a>.</p>
8+
<p>If you&#39;re not, and you haven&#39;t sorted it out from the quote above, CocoaPods is a tool that&#39;s let us manage our libraries and their dependencies in our Objective-C projects. This means:</p>
9+
<ol>
10+
<li>No more wasted time downloading all the libraries the one we want to use depends on.</li>
11+
<li>Smart and safe version management, specially when we&#39;re working on a project with other people, which is 90% of the time.</li>
12+
</ol>
13+
<p>To <em>&quot;get my hands dirty&quot;</em> with CocoaPods I made this little project called <a href="https://github.com/mokagio/justninegags">JustNineGags</a>, feel free to check it out on GitHub.</p>
14+
<h2 id="why-should-i-use-it-">Why should I use it?</h2>
15+
<p>Because it&#39;s awesome! It makes development faster and easier, and also safer! It easier to work in teams and keep the libraries versions even. Should I go on? Ok! Just think about this: you won&#39;t download and move in your project a library anymore, <code>pod</code> will do it all for you!</p>
16+
17+
<h2 id="installing-cocoapods">Installing CocoaPods</h2>
18+
<p>Installing CocoaPods is as simple as installing all the other Ruby Gems, I shouldn&#39;t even writing this, as what&#39;s written in the <a href="http://cocoapods.org/#install">install section</a> is more than enough, anyway:</p>
19+
20+
<pre><code class="">gem <span class="hljs-keyword">install</span> cocoapods
21+
</code></pre><p>Once the installation is completed run:</p>
22+
23+
<pre><code class="">pod <span class="hljs-built_in">setup</span>
24+
</code></pre><p>This will, guess what, setup everything CocoaPods needs on your system. You should see an output like this:</p>
25+
26+
<pre><code class="">Setting <span class="hljs-keyword">up</span> CocoaPods master repo
27+
Cloning spec repo <span class="hljs-string">&#x27;master&#x27;</span> from <span class="hljs-string">&#x27;&lt;a href=&#x27;</span>http<span class="hljs-variable">s:</span>//github.<span class="hljs-keyword">com</span>/CocoaPods/Specs.git<span class="hljs-string">&#x27;&gt;https://github.com/CocoaPods/Specs.git&lt;/a&gt;&#x27;</span> (branch <span class="hljs-string">&#x27;master&#x27;</span>)
28+
Setup completed (<span class="hljs-keyword">read</span>-<span class="hljs-keyword">only</span> access)
29+
</code></pre><p>Done! :)</p>
30+
31+
<p><em>You should avoid using <code>sudo</code> otherwise everything else you&#39;ll do with <code>pod</code> will need to use <code>sudo</code> as well. And this mean that the folders and file that are gonna be created will be owend by <code>root</code> instead that by you.</em></p>
32+
33+
<h2>Using CocoaPods</h2>
34+
35+
<p>Again, everything written on the <a href="http://cocoapods.org/#get_started">website</a> is pretty straightforward.</p>
36+
37+
<p>Go in the root folder of your Objective-C project and create a file named <code>Podfile</code>, with whatever editor you like. We&#39;ll use this file to list all the libraries, <em>pods</em>, we need in the project. The JustNineGags <code>Podfile</code> content is:</p>
38+
39+
<pre><code class=" hljs ruby">platform <span class="hljs-symbol">:ios</span>
40+
pod <span class="hljs-string">&#x27;MBProgressHUD&#x27;</span>, <span class="hljs-string">&#x27;~&gt; 0.5&#x27;</span>
41+
pod <span class="hljs-string">&#x27;Reachability&#x27;</span>, <span class="hljs-string">&#x27;~&gt; 3.1.0&#x27;</span>
42+
</code></pre>
43+
<h3>Adding a Pod</h3>
44+
45+
<p>As you can see adding a Pod is really easy, just go on <a href="http://cocoapods.org">CocoaPods website</a>, look for the it, and then add it to the <code>Podfile</code> using it&#39;s name and the version you need.</p>
46+
47+
<h3>Installing the Pods</h3>
48+
49+
<p>Right now we&#39;ve told CocoaPods the Pods we need but they aren&#39;t yet in out project. So let&#39;s run</p>
50+
51+
<pre><code class="">pod <span class="hljs-keyword">install</span>
52+
</code></pre><p>This will download all the libraries we&#39;ve asked for, and all their dependencies. Sweet!</p>
53+
54+
<p>The first time we run <code>pod install</code> something else will happen, a <code>Pods/</code> folder, a <code>Podfile.lock</code>, and a <code>YourProjectName.xcworkspace</code> will be created.</p>
55+
56+
<p><strong>Important!</strong> From now on remember to open your project through the <code>YourProjectName.xcworkspace</code> file, otherwise the pods won&#39;t be loaded by Xcode.</p>
57+
58+
<p>That&#39;s all folks! :)</p>
59+
60+
<h3>What should we track?</h3>
61+
62+
<p>Using CocoaPods adds some files and folders to our project, which of those should we track in our repo, and which should be left aside, adding them to the <code>.gitignore</code>? That of course assuming you&#39;re using git, and you definitely should. Let&#39;s have a look at the new stuff:</p>
63+
64+
<ul>
65+
<li><code>Podfile</code>, we definitely <b>need</b> this one, as all the pods we need are listed in it.</li>
66+
<li><code>Podfile.lock</code>, as for all the other library management systems, we <b>need</b> this one too, because it&#39;s used to assure all the developers are using the same versions of the pods and their dependencies.</li>
67+
<li><code>Pods/</code>, we <b>don&#39;t need</b> to track this folder, it&#39;s created by <code>pod install</code>, and all it&#39;s content is downloaded for us from other repos.</li>
68+
<li><code>YourProjectName.xcworkspace</code>, we <b>don&#39;t need</b> this one either, because it&#39;s generated by <code>pod install</code> too.</li>
69+
</ul>
70+
71+
<h2>What&#39;s coming next?</h2>
72+
73+
<p>How to setup our own pods. I&#39;ll probably write a little and simple Category to add other colors to the <code>UIColor</code> factories, stay tuned!</p>
74+

<h2>Update 2013-01-06</h2>
78+
79+
<p>To implement HTTP requests in <a href="https://github.com/mokagio/justninegags">JustNineGags</a> I used <code><a href="https://github.com/nfarina/webrequest">SMWebRequest</a></code> because I&#39;m too lazy to write everything by myself. <code>SMWebRequest</code> wasn&#39;t a Pod yet so I opened an <a href="https://github.com/nfarina/webrequest/issues/7">issue</a> asking good guy <a href="https://twitter.com/nfarina">nfarina</a> to add it. In less than 12 hours the Pod was added! :D</p>
