OC mixed with Swift, implementation of the three scenarios

Multi-language coexistence period, must be mixed into a way to achieve coexistence and OC Swift languages ​​in more than shadow turned out to be so simple

The first scenario, App achieved mixed

1. Create a bridge file *.h
   a new bridge file, New File choose  Header File to create a
2. Specifies the bridge file
   project->targets->Build Setting->All->Swift Compilter General->Objective-C-Bridging-Header to specify the new bridge just the file
   
3. OC import header file ( *.h) to the bridge file
   such as:#import "Log.h"
   
4. Complete the call
   in Swiftdirectly call the file

Note: Create a file for the first time in OC Swift project, Xcodeit will automatically be prompted to create a bridge file

The second scene, Framework implemented in mixed

1. Creating Famework
   Once created will generate a header file with the same name*.h
2. The OC header ( *.h) as the public header file
   project->targets->Build Phases->Headers->Publicdirectly dragged
   
3. OC import header file ( *.h) to a header file of the same name
   , such as:#import "Log.h" 
4. Complete the call
   in external Swiftfiles called directly
   
   Note: external classes and methods must be  public marked before visit

The third scenario, Pod the package realized mixed

After completing the second scenario, add the *.podspecfiles to achieve  Pod package

1. Generation  *.podspec
   to run the command  pod spec create [name] generates  *.podspec a file

2. Editing  *.podspec
   in  *.podspec in the header file OC ( *.hset) discloses headers
   such as:spec.public_header_files = "Log.h"

    #完整的文件信息
    Pod::Spec.new do |spec|
        spec.name         = "OCSwiftFramework"
        spec.version      = "0.0.1"
        spec.summary      = "OCSwiftFramework"
        spec.description  = <<-DESC
                        OCSWiftFramework
                        DESC
        spec.homepage     = "https://www.ichochy.com"
   
        spec.license      = "MIT"
        # spec.license      = { :type => "MIT", :file => "FILE_LICENSE" }
        spec.author             = { "MLeo" => "[email protected]" }
   
        spec.platform = :osx
        spec.osx.deployment_target = "10.10"
   
        spec.source       = { :git => "https://github.com/iChochy/HelloWorld.git", :tag => "#{spec.version}" }
   
        spec.source_files  = "**/*.{h,m,swift}"
        spec.exclude_files = "Info.plist"
        spec.public_header_files = "Flog.h"
   
        spec.swift_version = "4.2"
    end
   

3. Verify  *.podspec
   the Run command  pod lib lint to complete verification
4. Complete call a. Run command  pod trunk push [NAME.podspec] to complete the publication
   b.  Podfile Add  pod "[name]"c. Run the command  pod install to complete the  pod installation

   . d After installation directly call
   Note: Available  pod "[name]", :path => "[path]" local designated
