将GameKit键添加到info plist文件中（错误）

Question

我在“功能”标签上有一个“为您的信息plist文件添加GameKit键”错误。那是什么意思？

Gamekit修复Inf​​o.plist http://i.stack.imgur.com/zVUev.png

  

只需在 Info.plist 中的必需的设备功能中添加项目。

来自文档：

  

如果您的应用需要（或明确禁止）游戏中心（iOS 4.1及更高版本），请包含此密钥。

Answer 2

我需要从命令行（在CI中）执行此操作。这是我的方式。

# make a copy of the Info.plist
cp Info.plist before.plist

# open xcode and hit Fix issue button
# compare the results
diff Info.plist before.plist

结果

<       <string>gamekit</string>

更多细节

cat Info.plist | grep gamekit --context=3

返回：

<key>UIRequiredDeviceCapabilities</key>
<array>
    <string>armv7</string>
    <string>gamekit</string>
</array>

因此可以使用以下代码段与https://jsfiddle.net/rntshg76/4/一起执行与命令行中的按钮相同的操作：

# Adds UIRequiredDeviceCapabilities item to Info.plist
# || true prevents command line from failing if key already exists
/usr/libexec/PlistBuddy -c "Add :UIRequiredDeviceCapabilities array" Info.plist || true

# Add <string>gamekit</string> to array (at index 1) in Info.plist
# considering index 0 is already there and contains armv7
# Running Add multiple times will append a new line each time
# Here, we do it only if not already present
if grep -q "<string>gamekit</string>" Info.plist; then
    echo gamekit already present
else
    /usr/libexec/PlistBuddy -c "Add UIRequiredDeviceCapabilities:1 string gamekit" Info.plist
