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。

你可以打印当前所有的NSUserDefaults到日志:

键:

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

键和值:

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

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

你可以NSLog你设置的每个值，比如:

NSLog(@"%@",[[NSUserDefaults standardDefaults] stringForKey:@"WhateverTheKeyYouSet"]);

在Swift 4.0中

//func dictionaryRepresentation() -> [String : AnyObject]

因为NSUserDefaults.standardUserDefaults()返回[String: AnyObject]

我们将它转换到NSDictionary中。然后用括号'()'把它括起来将允许我们调用。allkeys或。allvalues就像你在任何NSDictionary上一样

 print((UserDefaults.standard.dictionaryRepresentation() as NSDictionary).allKeys)

它将在更高版本的SWIFT 4上工作

只需要把代码放在AppDelegate的any方法中，并在那里设置断点

**> let path =
> NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory,
> FileManager.SearchPathDomainMask.userDomainMask, true).first**

当你运行一个项目，打印“路径”，你会得到路径到达信息。使用userdefaults进行Plist 然后到finder，粘贴这个路径 那份文件找到你了
