有没有办法直接看到什么被保存到NSUserDefaults ?我想看看我的数据保存是否正确。


当前回答

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;
    ...

斯威夫特3

print(UserDefaults.standard.dictionaryRepresentation())

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。

它将在更高版本的SWIFT 4上工作

只需要把代码放在AppDelegate的any方法中,并在那里设置断点

**> let path =
> NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory,
> FileManager.SearchPathDomainMask.userDomainMask, true).first**

当你运行一个项目,打印“路径”,你会得到路径到达信息。使用userdefaults进行Plist 然后到finder,粘贴这个路径 那份文件找到你了

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]);
    }
}
