I. How to use a third-party framework
* Search online/or directly on the SDK website
* Find the corresponding download location
* Download SDK package corresponding to application development platform
* Read through the SDK's documentation to integrate the SDK with Project engineering
* After integrating SDK package, use the SDK function according to the prompt demo code (using steps)

Iv. When using the view model, note
* Which view model to use, the header file of which view model should be imported

///////////////////////////////////////2///////////////////////////////////////

View Model Transformation principle:
//dictionary array to model array
Nsarray *themeitems = [tjtopicitem mj_objectarraywithkeyvaluesarray:responseobject[@ "List"];

//Create variable array
Nsmutablearray *themeitem = [Nsmutablearray array];

traversing an array model
For (Tjtopicitem *item on themeitems) {
//Create a View model object
Tjthemeviewmodel *VM = [Tjthemeviewmodel alloc] init]
Vm.item = Item;
    
//Save view View Model
[Themeitem ADDOBJECT:VM];
self.themeviewmodels = Themeitem;
}

installing Alcatraz in Xcode 7
first step: Turn off Xcode.
Step Two: If you have previously installed Alcatraz, uninstall it. Run Command
rm-rf ~/library/application\ Support/developer/shared/xcode/plug-ins/alcatraz.xcplugin

Step Three: The most critical step is to run the command:
Find ~/library/application\ support/developer/shared/xcode/plug-ins-name info.plist-maxdepth 3 | xargs-i{} Defaults write {} dvtplugincompatibilityuuids-array-add defaults read/applications/xcode.app/contents/info Dvtplugincompatibilityuuid sudo xcode-select--reset

Fourth step: Install Alcatraz.
Curl-fssl https://raw.github.com/supermarin/Alcatraz/master/Scripts/install.sh | sh

I. Swift and OC code mixing
using Swift in OC
* #import "occallswift-swift.h"
using OC files in Swift
* You must create a/= Configuration bridging file

first, the installation and use of Cocoapods:
1. Upgrade Gems first (can be omitted)
sudo gem update--system

2. Switch the cocoapods data source
"First Delete, then add, view"
gem sources--remove https://rubygems.org/
Gem sources-a https://ruby.taobao.org/
Gem Sources-l

3. Installing Cocoapods
sudo gem install cocoapods
or (e.g. 10.11 system) sudo gem install-n/usr/local/bin cocoapods

4. Setting up the Pod warehouse
pod Setup

5. Testing
"If there is a version number, the installation was successful"
pod--version

6.cocoapods Uninstall
sudo gem uninstall cocoapods


7. View Cocoapods Download Progress
CD ~/.cocoapods to this directory, use the DU-SH * command to view

8. Installation
pod Install--no-repo-update
pod Update--no-repo-update

9. Description
Platform:ios, ' 7.0 ' is used to set the minimum iOS version supported by all third-party libraries
pod ' sdwebimage ', ' ~>3.7.5 ' sets the frame name and version number
rule for version number:
' >1.0 ' can install any version above 1.0
' >=1.0 ' can install any version above or equal to 1.0
' <1.0 ' any version less than 1.0
' <=1.0 ' any version less than or equal to 1.0
' ~>0.1 ' any version above or equal to 0.1, but does not contain a version above 1.0
' ~>0 ' any version, equivalent to the non-specified version, by default the latest version number

10. General procedure after installing the framework using the Pod Install command:
01 Analysis Dependency: This step analyzes podfile to see dependencies between different class libraries. If more than one class library relies on the same class library, but relies on different versions, Cocoapods automatically sets a compatible version.
02 Download Dependency: Download the specified version of the class library to a local project, based on the results of the analysis dependency.
03 Build Pods Project: Create a Pods project that is designed to compile and manage third-party frameworks, Cocoapods will add the required frameworks, libraries, and so on to the project, and configure them accordingly.
04 Integration Pods Project: Integrate pods and projects into one workspace and set up file links.


Second, cocoapods command line update (install) step "Update"

$ sudo gem update--system//update gem First, domestic need to switch source
$ gem Sources--remove https://rubygems.org/
$ gem sources-a https://ruby.taobao.org/
$ gem sources-l
\*\*\* current SOURCES \*\*\*
https://ruby.taobao.org/
$ sudo gem install cocoapods//install Cocoapods
$ pod Setup

COMMAND + B:
compile the code. We write a time code, compile it first, and see if there are any grammatical errors, which is a good habit. In fact, in the process of Xcode running the project, through a few stages, compiled---link, build target file, execute.
