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。

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

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;
    ...

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

对于希望找到存储在模拟器中的首选项的新位置的用户。 这是我找到存储值的地方。

/Users/vikas/Library/Developer/CoreSimulator/Devices/CE5A0444-BD98-4FEE-A839-92728D6E9895/data/Containers/Data/Application/F7430839-ED2C-408A-8A8E-FE7FFAABA8E2/Library/Preferences

因为我们可以看到有很大的标识符，很难从终端猜出来，所以我建议在终端或finder中搜索它们。

文件名应该以{bundle id}结尾。Plist，例如com.sellerbuddy.online.plist，这样你就可以直接进入终端，输入你的应用程序包标识符。

find ~/Library/Developer/CoreSimulator/Devices -type f -name "com.sellerbuddy.online.plist"
