在Swift 2.2中

let path = NSSearchPathForDirectoriesInDomains(.LibraryDirectory, .UserDomainMask, true)
let folder = path[0]
NSLog("Your NSUserDefaults are stored in this folder: \(folder)/Preferences")

将打印出NSUserDefaults在Xcode调试控制台的plist文件夹位置。复制路径字符串。打开Finder，选择Go菜单项中的“转到文件夹”，粘贴路径字符串。双击plist文件。你会在Xcode编辑器中看到内容。

只能在模拟器中工作

谢谢@Niels Castle

模拟器应用程序

这个shell脚本搜索应用程序的名称，获取bundle id，并打开包含Plist文件的文件夹。

#!/bin/bash

appname="$1"
[ -z $appname ] && read -p "Application name : " appname

apppath=$(find ~/Library/Developer/CoreSimulator/Devices/ -name "$appname.app" -print -quit)
if [[ ! -z $apppath ]]; then
    appbundle=$(osascript -e "id of app \"$apppath\"")
    find ~/Library/Developer/CoreSimulator/Devices/ -name "$appbundle.plist" -exec bash -c 'open "$(dirname "$1")"' -- {} \;
else
    echo "No application found by that name: $appname.app"
fi

扩展脚本版本

用法:iphone- App -文件夹“My App”

#!/bin/bash
appname="$1"
[ -z "$appname" ] && read -p "Application name : " appname

apppath=$(find ~/Library/Developer/CoreSimulator/Devices -name "$appname.app" -print -quit)
if [[ ! -z $apppath ]]; then
    appbundle=$(osascript -e "id of app \"$apppath\"")
    echo "Found app $appname (${appbundle})"
    echo -e "\033[1;30m$apppath\033[0m"
    plists=$(find ~/Library/Developer/CoreSimulator/Devices -name "$appbundle.plist" -print -quit)
    count=$(echo plists | wc -l | sed "s/ //g")
    if [[ $count -eq 1 ]] && [[ -f "$plists" ]]; then
        echo -e "\033[1;32mUserDefaults found for $appname\033[0m"
        echo -e "\033[1;30m$plists\033[0m"
        plistutil -i "$plists"
        /usr/bin/open $(dirname "$plists")
    elif [[ ${#plists} -gt 0 ]]; then
        echo -e "\033[1;32mUserDefaults found for $appname\033[0m"
        i=1
        while read line; do
            echo "[${i}] ${line} "
            i=$((i+1))
        done < <(echo "$plists")
        echo
        read -p "Select defaults to read: [1-${count}] " choice
        plist=$(echo ${plists} | sed -n "${choice}p")
        plistutil -i "$plist"
        /usr/bin/open $(dirname "$plist")
    else
        echo -e "\033[31mNo UserDefaults plist found for $appname\033[0m"
    fi
else
    echo -e "\033[31mNo application found by that name: $appname.app\033[0m"
fi

Mac应用程序

defaults read com.bundleid.app

很简单，因为plist文件名为<app-bundle-identifier>。Plist，你可以使用find命令找到它的路径。但如果你搜索整台电脑，会花很长时间，所以你必须选择一个好的范围，比如Xcode 6的~/Library/Developer/CoreSimulator。

例子:

查找~/Library/Developer/CoreSimulator -type f -name com.awesome.app.plist

输出将是这样的…

\用户hlung / Library /开发商CoreSimulator / / B61913F6-7D7C-4E45-AE2F-F45220A71823带给您Containers /数据/应用程序/ E4CC51CF-11E5-4168-8A74-6BAE3B89998F / Library / Preferences / com . awesome app。plist

然后你可以使用open命令。或者如果使用iTerm2，只需在路径上单击命令打开它。

使用下面的代码。

NSLog(@"NSUserDefault: %@", [[NSUserDefaults standardUserDefaults] dictionaryRepresentation]);

你可以打印出应用程序的首选项目录的路径:didFinishLaunchingWithOptions:回调在你的AppDelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    print(FileManager.default.urls(for: .preferencePanesDirectory, in: .userDomainMask).first!)
    return true
}

然后你可以直接查看plist文件，看看里面保存了什么。
