Flutter-代码签名“ App.framework”失败

如何解决Flutter-代码签名“ App.framework”失败

我是新手，想在iOS上实现我的第一个应用程序，但是，自上周以来，我正面临着这个问题，并试图解决它。

1。运行“ Flutter build ios”后，构建和签名成功

2。项目存档也很成功

（问题） 但是，当我单击验证应用程序时。我收到以下问题，我花了很多时间并进行了很多调试，但找不到导致此问题的原因。

解决方法

以下是解决此错误的方法： 您必须在xcode中添加脚本，以删除第3方库的未使用代码。 当您使用xcode打开flutter iOS项目时，您会在构建阶段部分看到flutter已经有一个脚本。不要弄乱这个脚本，相反，您将添加一个新脚本。 这张图片如下：

然后您将看到类似这样的内容：

在此之后，打开运行脚本并放置以下代码：

# Type a script or drag a script file from your workspace to insert its path.APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"
# This script loops through the frameworks embedded in the application and
# removes unused architectures.

find "$APP_PATH" -name 'FRAMEWORK_NAME*.framework' -type d | while read -r
FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"

EXTRACTED_ARCHS=()

for ARCH in $ARCHS
do
echo "Extracting $ARCH from $FRAMEWORK_EXECUTABLE_NAME"
lipo -extract "$ARCH" "$FRAMEWORK_EXECUTABLE_PATH" -o
"$FRAMEWORK_EXECUTABLE_PATH-$ARCH"
EXTRACTED_ARCHS+=("$FRAMEWORK_EXECUTABLE_PATH-$ARCH")
done

echo "Merging extracted architectures: ${ARCHS}"
lipo -o "$FRAMEWORK_EXECUTABLE_PATH-merged" -create
"${EXTRACTED_ARCHS[@]}"
rm "${EXTRACTED_ARCHS[@]}"

echo "Replacing original executable with thinned version"
rm "$FRAMEWORK_EXECUTABLE_PATH"
mv "$FRAMEWORK_EXECUTABLE_PATH-merged" "$FRAMEWORK_EXECUTABLE_PATH"

done

如果遇到错误指出脚本中存在语法错误，请尝试删除在尝试复制脚本时可能已复制的无法识别的字符 因为xcode不会处理它们，所以它发生在我身上。因此，将代码复制并放置在能够处理此类字符的其他代码编辑器中（例如，Visual Studio），然后从某些行的末尾删除不需要的字符。 所以现在总共有两个脚本在运行

,

经过大量搜索和尝试，我发现我在配置中出错，解决了此问题后，我设法验证了该应用并将其成功上传到App Store。
