设置App的编译阶段 (Build Phases)
<h1>设置App的编译阶段 (Build Phases) (共3步)</h1>
<p>1 在目标App的编译阶段(Build Phases)中，添加一个脚本运行阶段 (Run Script Phase)。

2 请确认该脚本运行阶段放置在所有阶段的最后。

3 将下面代码段的内容粘贴到新增的脚本运行阶段中。
<strong>在原有的脚本中，增强日志输入，以便于Debug</strong></p>
<pre><code># Output Log to /tmp/*_BSSDKRunScript.log
exec &gt; /tmp/${PROJECT_NAME}_${TARGET_NAME}_BSSDKRunScript.log 2&gt;&amp;1
echo &quot;Architectures trimming begins&quot;

echo &quot;APP_PATH:${APP_PATH}&quot;
# This script loops through the frameworks embedded in the application and
# removes unused architectures.
find &quot;$APP_PATH&quot; -name '*.framework' -type d | while read -r FRAMEWORK
do
FRAMEWORK_EXECUTABLE_NAME=$(defaults read &quot;$FRAMEWORK/Info.plist&quot; CFBundleExecutable)
FRAMEWORK_EXECUTABLE_PATH=&quot;$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME&quot;

EXTRACTED_ARCHS=()
echo &quot;Architectures to keep:${ARCHS}&quot;

<p>4 该步骤设置结束，用于在生成App时，把非对应CPU架构的Binary给清掉，以减小<strong>App</strong>的大小。</p>
