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。

对于OS X应用程序，使用默认命令行实用程序更简单，而不是寻找应用程序的默认plist文件。

NAME defaults -- access the Mac OS X user defaults system SYNOPSIS defaults [-currentHost | -host hostname] read [domain [key]] defaults [-currentHost | -host hostname] read-type domain key defaults [-currentHost | -host hostname] write domain { 'plist' | key 'value' } defaults [-currentHost | -host hostname] rename domain old_key new_key defaults [-currentHost | -host hostname] delete [domain [key]] defaults [-currentHost | -host hostname] { domains | find word | help } DESCRIPTION defaults allows users to read, write, and delete Mac OS X user defaults from a command-line shell. Mac OS X applications and other programs use the defaults system to record user preferences and other information that must be maintained when the applications aren't running (such as default font for new documents, or the position of an Info panel). Much of this information is accessible through an appli- cation's Preferences panel, but some of it isn't, such as the position of the Info panel. You can access this information with defaults

例子:

$ defaults read com.apple.Safari
{
    AutoplayPolicyWhitelistConfigurationUpdateDate = "2018-08-24 17:33:48 +0000";
    AutoplayQuirksWhitelistConfigurationUpdateDate = "2018-08-24 17:33:48 +0000";
    DefaultBrowserPromptingState2 = 4;
    ...

MacOS应用 进入:/Users/{User}/Library/Containers/com。{你的公司}。{your app}/Data/Library/Preferences，然后用Xcode打开你的app的pList。

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

这是您的UserDefaults键值将在plist文件中的整个路径。跟踪并找到你的应用程序包标识符。plist文件。

/Users/'您的用户名'/Library/Developer/CoreSimulator/Devices/4176EED3-B9FC-4C77-A25E-ASD201B9FDFG2/data/Containers/ data/ Application/56D7CE31-9A8B-4371-9B0F-9604E239423B0/Library/Preferences

这里的“4176EED3-B9FC-4C77-A25E-ASD201B9FDFG2”是您的设备ID

“56D7CE31-9A8B-4371-9B0F-9604E239423B0”是您的申请ID

我通常通过在查找器中根据最近修改的日期对文件夹进行排序来获得它们。最近编辑的文件夹是我的设备ID和应用ID。
