CocoaPods is one of the best things I've found in the latest iOS app development. I use it to get the latest Github open source project as a framework and library in my project. The best part is the automatic management of the dependent library, so there is no need to drag and drop files and upload them to the blaa folder. Blaaa is just one simple pod install code, that's all! rest will be carried out using Cocoa -pods trust me, this will save you development time and your code will look clean and updated :)
If someone needs to know how to install Cocoapod just enter this into your terminal
sudo gem install cocoapods
and then create a PodFile (text to text file), as in the folder where your project is located.
platform :ios, 5.0 pod 'RestKit'
then finally at the terminal
pod install
Then see the magic :)
