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"

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

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]);
    }
}

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;
    ...

你可以NSLog你设置的每个值，比如:

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

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。
