Swift 5 Xcode 11.2解决方案

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!

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。

您可以检查数组中由返回的每个键的值

[[[NSUserDefaults standardUserDefaults] dictionaryRepresentation] allKeys]

print(UserDefaults.standard.dictionaryRepresentation())

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;
    ...

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)
