Installation and use of third-party network request library Alamofire in Swift

Installation and use of third-party network request library Alamofire in Swift

Alamofire is one of the more popular network request libraries in Swift: Https://github.com/Alamofire/Alamofire. Here we introduce the installation and use of this library.

One, install package management tool Cocoapods

As the domestic easy to be wall, the speed is very slow, here we use the provided source http://ruby.taobao.org/

Gem sources--remove Https://rubygems.org/gem sources–a Http://ruby.taobao.org/gem sources–l

First use the following command to upgrade the Ruby version:

update --system

Wait for the update to complete.

Then use the Gem command to download the installation Cocoapods:

install cocoapods

After installation, call the following command to make the Cocoapods settings (you can see if the installation was successful through the pod command):

pod setup

After executing the above command, the installation is successful! The following describes how to use Cocoapods.

Second, use cocoapods download Alamofire Library

We first create a swift demo project named demo, and a project file is generated demo.xcodeproj

Let's see if we can support the Alamofire three-party library

Pod Search Alamofire

Normally, some information about the three-party library is output, as well as the version number.

The following important work has begun.

Create a Pod profile with the file name Podfile, note that there is no extension, for an introduction to the Podfile file refer to: http://blog.haohtml.com/archives/16970.

The contents are as follows:

SOURCE ' Https://github.com/CocoaPods/Specs.git ' Platform:ios, ' 9.0 ' Use_frameworks!target ' demo ' dopod ' Alamofire ',: git = ' https://github.com/Alamofire/Alamofire.git ',: Tag = ' 3.4.0 ' End

Then execute the Install command

Pod Install

After the successful installation, there will be more than one demo.xcworkspace of the project files, later we develop again, we need to use this file, discard the original demo.xcodeproj file.

At this point the project directory is as follows:

The Pods folder contains the downloaded third-party dependent libraries.

Open the project file Demo.xcworkspace. The project structure at this point is as follows:

Third, the use of Alamofire library

We opened the Viewcontroller.swift and introduced the Alamofir library. Add an "import Alamofire" below the import UIKit line in the header of the file , make sure you do this step, or you will not use the library's API.

Then the super in the viewdidload () method . Viewdidload() The following line, put Https://github.com/Alamofire/Alamofire one of the API code in, and then run the project, You can see some relevant information in the output panel of Xcode, which shows that these APIs can be called normally.

If we need to install another library, such as the layout of the three-party library Snapkit, first search

Pod Search Snapkit

Results such as:

Add a line "pod ' snapkit ', ' ~> 0.14.0 '" in the Target xxx do ... end block as prompted, and the file reads as follows: Podfile

SOURCE ' Https://github.com/CocoaPods/Specs.git ' Platform:ios, ' 9.0 ' Use_frameworks!target ' demo ' dopod ' Alamofire ',: git = ' https://github.com/Alamofire/Alamofire.git ',: Tag = ' 3.4.0 ' pod ' snapkit ', ' ~> 0.14.0 ' end

Execute the installation command again

Pod Install

Can. You should see the Snapkit library in the Pods directory at this time. finally
