Flutter_Library not loaded: @rpath/App.framework/App

问题描述

更新了FlutterSDK，模拟器运行无问题，真机运行崩溃

报错结果如下：

dyld[15588]:

原因分析：

经过排查，发现是Flutter的App.framework没有导入

---

解决方案1：

打开 Pods-xx-frameworks.sh，然后添加以下代码

install_framework "${PODS_ROOT}/../merchant_flutter/.ios/Flutter/App.framework"

• ../merchant_flutter这段路径可以复制 Podfile内flutter_application_path值

• xx：工程名称

• 参考链接

• 此种解决方式存在弊端：每次工程进行pod install以后Pods-xx-frameworks.sh 文件将会被重置，添加的代码会被删除。可以采用解决方案2

解决方案2：

• 打开 TARGETS -> Build Phases -> + -> New Run Script Phase
• 添加指令

install_framework()
{
  if [ -r "${BUILT_PRODUCTS_DIR}/$1" ]; then
    local source="${BUILT_PRODUCTS_DIR}/$1"
  elif [ -r "${BUILT_PRODUCTS_DIR}/$(basename "$1")" ]; then

    local source="$1"
  fi

  local destination="${TARGET_BUILD_DIR}/${FRAMEWORKS_FOLDER_PATH}"

  if [ -L "${source}" ]; then
    echo "Symlinked..."
    source="$(readlink "${source}")"
  fi

  if [ -d "${source}/${BCSYMBOLMAP_DIR}" ]; then
    # Locate and install any .bcsymbolmaps if present, and remove them from the .framework before the framework is copied
    find "${source}/${BCSYMBOLMAP_DIR}" -name "*.bcsymbolmap"|while read f; do
      echo "Installing $f"
      install_bcsymbolmap "$f" "$destination"
      rm "$f"
    done
    rmdir "${source}/${BCSYMBOLMAP_DIR}"
  fi

  # Use filter instead of exclude so missing patterns don't throw errors.
  echo "rsync --delete -av "${RSYNC_PROTECT_TMP_FILES[@]}" --links --filter \"- CVS/\" --filter \"- .svn/\" --filter \"- .git/\" --filter \"- .hg/\" --filter \"- Headers\" --filter \"- PrivateHeaders\" --filter \"- Modules\" \"${source}\" \"${destination}\""

  local basename
  basename="$(basename -s .framework "$1")"
  binary="${destination}/${basename}.framework/${basename}"

  if ! [ -r "$binary" ]; then
    binary="${destination}/${basename}"
  elif [ -L "${binary}" ]; then
    echo "Destination binary is symlinked..."
    dirname="$(dirname "${binary}")"
    binary="${dirname}/$(readlink "${binary}")"
  fi

  # Strip invalid architectures so "fat" simulator / device frameworks work on device
  if [[ "$(file "$binary")" == *"dynamically linked shared library"* ]]; then
    strip_invalid_archs "$binary"
  fi

  # Resign the code if required by the build settings to avoid unstable apps
  code_sign_if_enabled "${destination}/$(basename "$1")"
