Question

我想在Memory for Memory Leak中运行我的iPad应用程序并使用终端进行对象分配。

我也完成了goggling。我知道如何使用以下命令打开终端：

open /Developer/Applications/Instruments.app

我也尝试过以下命令。

instruments -t "/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Resources/templates/Leaks.tracetemplate" -/Users/iOSRider/Downloads/samplecode/build/Release-iphoneos/sample.app

但我得到以下错误：

`-[NSAlert alertWithError:] called with `nil NSError.

将显示一般错误消息，但用户应该得到更好的效果。

然后我尝试了

instruments -w "cd73f2aadff0726a923b22bc69fdca4420f08ffb" -t "/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/Resources/templates/Leaks.tracetemplate" -/Users/iOSRider/Downloads/samplecode/build/Release-iphoneos sample.app

但我得到以下错误：

Instruments Trace Error : Failed to start trace.

我也尝试过以下命令

 instruments -t /Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate /Users/iOSRider/Library/Developer/Xcode/DerivedData/sample-ejuawqyrosinegcnvzhyrjhxkyue/Build/Products/Debug-iphonesimulator/sample.app

但我现在收到新错误

Instruments Trace Error : Failed to start trace.

我想从Jenkins运行仪器，这就是我在终端测试的原因。

我正在使用带有iOS 6.1.3的iPad 2。如果它也适用于模拟器，我很好。

如果我犯了任何错误，请指导我。

您似乎缺少特定的设备ID（[-w device]）。虽然模板可能有它，但我认为您无论如何都需要在命令行中指定它。

我做了一些谷歌搜索，发现this article。

以下是基于该文章的配对向下脚本，您可以使用它从命令行运行Instruments。

runTests.sh

XCODE_PATH=`xcode-select -print-path`
TRACETEMPLATE="$XCODE_PATH/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate"
APP_LOCATION=$2
DEVICE_ID=$3

if [ ! $# -gt 1 ]; then
    echo "You must specify the app location and the test file."
    echo "\t (optionally supply unique device ID of physical iOS device)"
    echo "\t eg. ./build.sh suite.js <xcodeproject directory>/build/Debug-iphonesimulator/myapp.app <device-udid>"
    exit -1
fi

# If running on device, only need name of app, full path not important
if [ ! "$DEVICE_ID" = "" ]; then
  RUN_ON_SPECIFIC_DEVICE_OPTION="-w $DEVICE_ID"
  APP_LOCATION=`basename $APP_LOCATION`
fi

# Kick off the instruments build
instruments \
$RUN_ON_SPECIFIC_DEVICE_OPTION \
-t $TRACETEMPLATE \
$APP_LOCATION \
-e UIARESULTSPATH /var/tmp
