很简单，因为plist文件名为<app-bundle-identifier>。Plist，你可以使用find命令找到它的路径。但如果你搜索整台电脑，会花很长时间，所以你必须选择一个好的范围，比如Xcode 6的~/Library/Developer/CoreSimulator。

例子:

查找~/Library/Developer/CoreSimulator -type f -name com.awesome.app.plist

输出将是这样的…

\用户hlung / Library /开发商CoreSimulator / / B61913F6-7D7C-4E45-AE2F-F45220A71823带给您Containers /数据/应用程序/ E4CC51CF-11E5-4168-8A74-6BAE3B89998F / Library / Preferences / com . awesome app。plist

然后你可以使用open命令。或者如果使用iTerm2，只需在路径上单击命令打开它。

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]);
    }
}

您可以检查数组中由返回的每个键的值

[[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allKeys]

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)

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;
    ...

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"
