你可以NSLog你设置的每个值，比如:

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

您可以使用它来获得用户首选项、缓存和许多其他数据的完整路径

print (NSSearchPathForDirectoriesInDomains(。文件目录。

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。

享受吧!

使用下面的代码。

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

在阅读了这个问题的公认答案后，我把这个简单的脚本放在一起，打开iOS模拟器用来存储NSUserDefaults首选项的plist文件，虽然它假设了某种设置(非常适合我的设置)，但它可以作为其他人的起点。

$ cat open-prefs-plist.sh
#!/bin/sh

# The project name based on the workspace path, e.g. "MyProject" from "./MyProject.xcworkspace"
WORKSPACE_NAME=$(echo `find . -name *.xcworkspace -type d -exec basename {} \;` | cut -d'.' -f1)
SIMULATOR_PATH="$HOME/Library/Application Support/iPhone Simulator"
# The App's bundle ID taken from its info plist, e.g "com.myproject" from "./MyProject/MyProject-Info.plist"
BUNDLE_ID=`/usr/libexec/PlistBuddy -c Print:CFBundleIdentifier $WORKSPACE_NAME/$WORKSPACE_NAME"-Info.plist"`
# Open all plist files in the simulator path that match the app's bundle ID 
# normally one per iOS version
find "$SIMULATOR_PATH" -name $BUNDLE_ID".plist" -type f -print0 \
    | while IFS= read -r -d '' PLIST; do
    echo $PLIST
    open "$PLIST"
done

例放置:

$ ls -1
MyProject
MyProject Tests
MyProject.xcodeproj
MyProject.xcworkspace
Podfile
open-prefs-plist.sh

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;
    ...
