Flutter-遠程Pod集成Flutter腳本優(yōu)化

最近块茁，我研究了下不依賴flutter開發(fā)環(huán)境的方式集成剥险，推送到遠程pod倉庫，以Framework形式在cocoapods中集成狰闪。

開始

1. 創(chuàng)建flutter_module:flutter create -t module flutter_module

KKdeMacBook-Pro:remotepod kaye$ flutter create -t module flutter_module

Wrote 12 files.

All done!
Your module code is in flutter_module/lib/main.dart.

添加依賴庫梢薪，比如:

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  shared_preferences: ^0.5.6

運行flutter pub get安裝依賴庫

KKdeMacBook-Pro:flutter_module kaye$ flutter pub get
Running "flutter pub get" in flutter_module...                      0.4s

build獲取產物

KKdeMacBook-Pro:flutter_module kaye$ flutter build ios --debug --no-codesign

我們先將各個產品，手動copy出來尝哆，放到一個文件夾ios_frameworks中備用秉撇。
note：這里我們先不用腳本，手動獲取秋泄，驗證一下pod能不能成功

2. 創(chuàng)建Pod:pod lib create KKFlutterPod

KKdeMacBook-Pro:remotepod kaye$ pod lib create KKFlutterPod

Running pod install on your new library.

Analyzing dependencies
Fetching podspec for `KKFlutterPod` from `../`
Downloading dependencies
Installing KKFlutterPod (0.1.0)
Generating Pods project
Integrating client project

[!] Please close any current Xcode sessions and use `KKFlutterPod.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

[!] Automatically assigning platform `ios` with version `9.3` on target `KKFlutterPod_Tests` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

 Ace! you're ready to go!
 We will start you off by opening your project in Xcode
  open 'KKFlutterPod/Example/KKFlutterPod.xcworkspace'

將上一步的ios_frameworks文件夾移動到Pod倉庫中琐馆，目錄結構如下：

3. 創(chuàng)建遠程Pod對應的Git倉庫

3.1 創(chuàng)建倉庫

這里自己測試使用的是GitHub，創(chuàng)建過程就不描述了恒序。

3.2 關聯倉庫

tip:或者你也可以先把遠程的Pod倉庫創(chuàng)建好瘦麸，clone下來，然后把創(chuàng)建的KKFlutterPod里面除了.git之外的所有文件拷貝到你clone的git倉庫中歧胁，從而省去關聯的關系

KKdeMacBook-Pro:flutter_module kaye$ cd ../KKFlutterPod/
KKdeMacBook-Pro:KKFlutterPod kaye$ git remote add origin https://github.com/yuyangkk/flutterpod.git

修改KKFlutterPod.podsepc文件,在其末尾添加如下：

s.static_framework = true
p = Dir::open("ios_frameworks")
arr = Array.new
arr.push('ios_frameworks/*.framework')
s.ios.vendored_frameworks = arr

podsepc文件.png

3.3 提交Pod到遠程

git add .
git commit -m "初始化"
git pull origin master
git push -u origin master

git tag -m "v0.1.0" -a 0.1.0
git push --tags

3.4 使用

pod 'KKFlutterPod', :git => 'https://github.com/yuyangkk/KKFlutterPod.git'

4. 腳本化

每次我們修改了flutter代碼滋饲，都要重新打包出來Framework厉碟，然后打上tag推送到遠程，這個過程雖然簡單屠缭，但是重復性很強箍鼓，所以考慮寫成腳本實現，以免有漏掉某些步驟呵曹！
ps：腳本有點不太規(guī)范款咖，是一邊看語法，一遍寫的奄喂，所以铐殃，有問題還請指出來

4.1. 編譯Framework并導出到指定位置

#cd ~/Desktop/remotepod/flutter_module
#獲取當前腳本目錄
projectURL=$(cd $(dirname $0); pwd)

#echo $projectURL

cd ${projectURL}

#out是指將編譯號的文件copy到指定的位置的路徑
if [ -z $out ]; then
    out='../KKFlutterPod/KKFlutterPod/ios_frameworks'
fi

echo "準備輸出所有文件到目錄: $out"

echo "清除所有已編譯文件"
#find . -d -name build | xargs rm -rf
flutter clean
rm -rf $out
rm -rf build

flutter packages get

echo "編譯flutter"
flutter build ios --debug --no-codesign
#如果是release包，將debug改為release
#flutter build ios --release --no-codesign
echo "編譯flutter完成"
mkdir $out

cp -r build/ios/Debug-iphoneos/*/*.framework $out
cp -r .ios/Flutter/App.framework $out
cp -r .ios/Flutter/engine/Flutter.framework $out

#本地Pod庫中提交代碼跨新，并修改version富腊，打上標簽，標簽和version保持一致域帐，自增
#上傳到pod蟹肘，請執(zhí)行腳本push_pod_spec.sh

4.2. 將導出的Framework上傳到遠程pod倉庫

projectURL=$(cd $(dirname $0); pwd)

#echo $projectURL

cd ${projectURL}

cd ../KKFlutterPod

echo "準備更新本地倉庫"
git pull

if [ $? -eq 0 ]; then
    echo "拉取遠程代碼成功"
else
    echo "拉取遠程代碼失敗"
    exit 1
fi

cd ${projectURL}

#修改KKFlutterPod.podspec中s.version          = '0.1.0'

# 讀取KKFlutterPod.podspec的第11行
# a=`cat KKFlutterPod.podspec |head -ne12`
# echo $a
a=`sed -n 11p KKFlutterPod.podspec `
# echo $a #s.version = '0.1.4'
# echo "刪除最右邊.開始向及其左邊的數據"
vs=${a##*.}
# echo $vs
oldNum=${vs%%\'*}
# echo '當前版本:'$oldNum
newNum=$((oldNum+1))
# echo '新版本:'$newNum

# echo "替換版本號"
v=0.1.$newNum
version="  s.version          = '$v'"
echo $version
sed -i '' "s/$a/$version/" KKFlutterPod.podspec

# echo "add 并且commit"

# git status
git rm --cached
git add .
git commit -m "修改版本$v"

# echo "添加tag"
git tag -a $v -m "$v"

# echo "連同tag推送到遠程"
git push
git push --tags

自此，差不多應該可以跑起來俯树，run一下試試帘腹，如果遇見build錯誤，請查看一下Xcode的bitcode是否打開了许饿，如果打開請關閉阳欲。

5. 問題

5.1 undefined symbol:OBJC_CLASS$_GeneratedPluginRegistrant

flutter插件編譯錯誤.png

這個問題，是因為導出的包是不支持模擬器的陋率，因為通過flutter開發(fā)環(huán)境導出的包球化，是可以支持模擬器的，所以猜測是我寫的腳本有問題瓦糟，等待后續(xù)優(yōu)化下筒愚，目前是只支持真機。

5.2 有關Framework包的大小

通過flutter build ios-framework --output=導出包路徑菩浙，獲取到debug巢掺、profile、release三種情況下的包劲蜻，其中包含的Flutter.framework的包大小分別是95MB陆淀、66.8MB、369.8MB先嬉，如果用release的包轧苫，推送到遠程pod庫的時候，會超過git的100MB限制疫蔓，可能會失敗，所以我們暫時只用了debug模式下的包，推送到遠程。
當然也有可能是我使用的命令有缺陷，如果有什么可以解決release環(huán)境下叫编，包過大的問題，請務必留言給我，感謝~~~

錯誤待續(xù)。樱哼。哀九。
