我根据Morion的建议构建了这个方法，以便更好地呈现。通过调用[self logAllUserDefaults]使用它

- (void) logAllUserDefaults
{
    NSArray *keys = [[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allKeys];
    NSArray *values = [[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allValues];
    for (int i = 0; i < keys.count; i++) {
        NSLog(@"%@: %@", [keys objectAtIndex:i], [values objectAtIndex:i]);
    }
}

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

我在桌面上保留了模拟器文件夹的快捷方式，在那里保存应用程序，即:

/Users/gary/Library/Application Support/iPhone Simulator/User/Applications

按最近的日期排序，然后进入最近的应用程序文件夹库/首选项，并在plist编辑器中查看文件。

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。

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。
