創(chuàng)建iOS項(xiàng)目

這里我們先創(chuàng)建一個(gè)空的iOS項(xiàng)目來(lái)模擬已有的項(xiàng)目柠逞，取名叫iOS_demo

創(chuàng)建flutter模塊

進(jìn)入你的項(xiàng)目同一層目錄,創(chuàng)建flutter模塊

flutter create -t module flutter_lab

關(guān)閉Bitcode

Flutter混合開(kāi)發(fā)還不支持Bitcode，所以在iOS工程檢查項(xiàng)目并關(guān)閉Bitcode

Bitcode.png

iOS項(xiàng)目相關(guān)配置

Flutter.xcconfig 內(nèi)容

#include "../flutter_lab/.ios/Flutter/Generated.xcconfig"
ENABLE_BITCODE=NO

Debug.xcconfig 內(nèi)容 （對(duì)應(yīng)的名字換成自己）

#include "Flutter.xcconfig"

// 如果使用了Cocoapods聂受，那么需要引入 cocoapods 的config文件饥悴，因?yàn)槿绻远x了config坦喘，那么cocoapods 的 config 就不會(huì)自動(dòng)指定了盲再。
#include "Pods/Target Support Files/Pods-iOS_demo/Pods-iOS_demo.debug.xcconfig"

Release.xcconfig

#include "Flutter.xcconfig"
FLUTTER_BUILD_MODE=release

// 如果使用了Cocoapods，那么需要引入 cocoapods 的config文件瓣铣，因?yàn)槿绻远x了config答朋，那么cocoapods 的 config 就不會(huì)自動(dòng)指定了。
#include "Pods/Target Support Files/Pods-iOS_demo/Pods-iOS_demo.release.xcconfig"

指定 config 文件棠笑，Debug 對(duì)應(yīng) Debug梦碗，Release 對(duì)應(yīng) Release

增加 Flutter 的腳本

image.png

"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build

修改Flutter腳本

在下載的flutter SDK中找到xcode_backend文件

image.png

注釋這段腳本

編譯iOS項(xiàng)目，在項(xiàng)目目錄下會(huì)生成一個(gè)flutter文件夾

image.png

右鍵項(xiàng)目 - Add Files to 'xxx' 【Options先選Create groups】蓖救，選擇Flutter目錄

image.png

但是flutter_assets 并不能使用Create groups 的方式添加洪规，只能使用Creat folder references 的方式添加進(jìn)Xcode項(xiàng)目?jī)?nèi)，否則跳轉(zhuǎn)flutter會(huì)頁(yè)面渲染失斞唷（頁(yè)面空白）斩例。

文件夾再Add Files to 'xxx'，選擇Creat folder references 巨柒；最終如下圖
