需要具备知识

flutter : 工程创建 , 插件与原生正逆向通道建立
iOS : swift或者oc基础 , 私有库配置

集成过程遇到的问题

集成过程按照官方文档可以很轻松的崽iOS原生实现出来 , 但是如果想过度到flutter上就需要一些注意 , 我在下方记录下我自己遇到的问题 .

1.第三方和系统自带的framework分别怎么添加到私有库中

a . 首先在我标识的路径下创建出一个frameworks文件夹(名字可以自己定义 , 只要之后路径能保持一致就好) . 然后将iflyAIUI.framework放入frameworks文件夹 .

b.然后打开dt_aiui_plugin.podspec , 在里面添加
s.vendored_frameworks = "**/iflyAIUI.framework"

c.然后继续添加系统自带的 framework :
s.frameworks = "CoreLocation","CoreTelephony","AVFoundation","AddressBook","AudioToolbox","Contacts","SystemConfiguration","QuartzCore","UIKit","Foundation","CoreGraphics"

2.系统自带的lib怎么添加到私有库中

就以我们应该添加的三个lib举例
s.libraries = "c++", "icucore", "z"

3.怎么添加资源文件 , 并加载出来

分别讲述aiui.cfg和meta_vad_16k.jet , 两个问价加载方式不一样 , meta_vad_16k.jet的路径我们控制不了 , 所以比较坑

3.1 aiui.cfg

a.创建resource文件夹 , 放在与framework同级处
b.将aiui.cfg文件放入resource中
c.在dt_aiui_plugin.podspec中添加路径
s.resources = "resource/*"
d.在代码处修改bundle的加载方法
NSString *cfgFilePath = [[NSBundle bundleForClass:[self class]] pathForResource:@"aiui" ofType:@"cfg"];

3.2 meta_vad_16k.jet

a.直接将meta_vad_16k.jet拖入到主工程中 , 目前找不到科大讯飞在哪里加载meta_vad_16k.jet的 , 只能找到路径 , 我猜测是在封装方法的内部调用bundle的加载 , 这个导致一个问题 , 如果我像aiui.cfg一样去存放文件 , 会加载不到资源 , 所以只能每次引用这个插件都在主工程中放入一次 .

最后我的podspec文件如下:

# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html.
# Run `pod lib lint dt_aiui_plugin.podspec' to validate before publishing.
#
Pod::Spec.new do |s|
  s.name             = 'dt_aiui_plugin'
  s.version          = '0.0.1'
  s.summary          = 'A new flutter plugin project.'
  s.description      = <<-DESC
A new flutter plugin project.
                       DESC
  s.homepage         = 'http://example.com'
  s.license          = { :file => '../LICENSE' }
  s.author           = { 'Your Company' => 'email@example.com' }
  s.source           = { :path => '.' }

#  s.vendored_frameworks = "frameworks/iflyAIUI.framework"
  s.vendored_frameworks = "**/iflyAIUI.framework"

  s.frameworks = "CoreLocation","CoreTelephony","AVFoundation","AddressBook","AudioToolbox","Contacts","SystemConfiguration","QuartzCore","UIKit","Foundation","CoreGraphics"

  s.source_files = 'Classes/**/*'
  s.dependency 'Flutter'
  s.library = "z"
  
  s.libraries = "c++", "icucore", "z"

  s.resources = "resource/*"

  s.platform = :ios, '9.0'

  # Flutter.framework does not contain a i386 slice.
  s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'i386' }
end```
