IOS facebook PoP first experience, iosfacebook

Speaking of pop, I learned a lot. I used the cocopods tool for the first time. Because I am not familiar with the operation, I learned it for a long time yesterday. From installation to running. To help more people learn about pop, I will write a brief introduction to the full version from cocopods to pop animation.

1. Install cocopods. Open the terminal and enter this command: gem sources -- remove https://rubygems.org/wait for a response and then enter: gem sources-a http://ruby.taobao.org/it is best to enter gem sources-l

Check whether

With this, we can install cocopods. Then enter sudo gem install cocoapods in the terminal to download it. At this time, you can have a cup of tea and wait until it is automatically downloaded. After the download is complete, you can use it. Create a project first. Then open the terminal again. First use the command line to enter the folder where I am placing it on the desktop (cd ~ /Desktop/file name) Input touch podfile on the terminal. Then you will see a red arrow pointing to the file. Now you can use the text editor that comes with mac to open it and enter:

Platform: ios, '7. 0'
Pod 'pop', '~> 1.0'

In this case, OK. Then, enter "pod install" in the terminal to download the file. After the download is complete, there will be multiple files in the Q & A folder:

Now you want to open xcworkspace, run it, and you don't have to open the original xocde. After running, check whether there are any errors. If you don't congratulate you, you can continue to do things.

Let's take a look at my code:
