Sqlite 文件位置核心数据

I managed to locate the sqlite file, and its in this path now:

Library/Developer/CoreSimulator/Devices/(numbers and letters)/data/Containers/Data/Application/(numbers and letters)/Documents/

(numbers and letters) stands for a folder that would be unique to your app/computer, but would look like this: 779AE2245-F8W2-57A9-8C6D-98643B1CF01A

I was able to find it by going into appDelegate.m, scrolling down to the

- (NSURL *)applicationDocumentsDirectory

method, and NSLogging the return path, like this:

// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory
{
NSLog(@"%@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory  inDomains:NSUserDomainMask] lastObject]);


return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}

This will give you your unique path, making it easier for you, because it is tricky locating it with the 2 unnamed folders/strings of letters and numbers.

Swift 4.2:

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
print(paths[0])

I was able to locate simulators folder with the next console output:

NSLog(@"app dir: %@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]);

in my case it was (Xcode 6 beta)

app dir: file:///Users/user/Library/Developer/CoreSimulator/Devices/D00C56D4-DDA3-47B0-9951-27D3B9EC68E8/data/Applications/6ABF3E54-37F5-4AD1-A223-F7467F601FB6/Documents/

If you're using Swift, this will return the document directory's absolute path:

func applicationDirectoryPath() -> String {
return NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).last! as String
}

I wrote a bash script for finding the location of your Application folder and the Application data folder within a simulator, you can download it here. Once you have unzipped the script you can navigate to the folder the script is in and use it. If you call it with no options it will give you a list of installed iOS simulators. You can then use the options to find your program. Writing:

./simulatorAppFolders -s "iPad Air" -i iOS-8-0 -a <MyApp>

will find the application folder and home area folder for your app on the iPad Air iOS 8 simulator. Here's an example:

MacBook-Air:_posts user$ ./simulatorAppFolders -s "iPad Air" -i iOS-8-0 -a MyApp
App folder = /Users/james/Library/Developer/CoreSimulator/Devices/6A9DEE93-FAEF-4BF4-9989-BC14CD38AEA0/data/Containers/Bundle/Application/8F64CD7F-A227-43D6-98AC-41D3919827CB
dataFolder = /Users/james/Library/Developer/CoreSimulator/Devices/6A9DEE93-FAEF-4BF4-9989-BC14CD38AEA0/data/Containers/Data/Application/96C40A21-5A5C-4399-839C-B155B8A72932

Update

There's an update to the original script which allows you to search based on the device type using a -d option. I've also written another script which makes a series of sensibly named folders so you can find your application and application documents. This script will make a folder called iOS_SIMULATORS in your home area and you can easily navigate to your application from there.

Like James Snook I created my own script to provide easier access to the simulator apps. I think it can be handy to many people getting here, other than me.

Unlike his script, mine is not a search tool, it creates a complete (and human readable) folder structure with all the devices/runtimes, and puts soft links to the apps in them.

You can get it in this Gist.

Run it every time you install an app in the simulator, or just run it every time you are going fetch an app for any reason (it will update, and open the devices folder in Finder).

If your app is using Core Data, it's just a matter of searching for the sqlite file in Terminal:

find ~ -name app_db_file_name.sqlite

The results will list the full path to the simulator folders containing your app.

I hacked this one-liner (Gist): find ~/Library/Developer/CoreSimulator/Devices/ -name device.plist -exec sh -c "/usr/libexec/PlistBuddy -c \"print UDID\" '{}' | tr '\n' ' '" \; -exec sh -c "/usr/libexec/PlistBuddy -c \"print name\" '{}' | tr '\n' ' '" \; -exec sh -c "/usr/libexec/PlistBuddy -c \"print runtime\" '{}' | sed -n 's/com\.apple\.CoreSimulator.SimRuntime\.\(.*\)/\1/p'" \;

This prints:

Update:

As someone pointed out here, it is also possible to run xcrun simctl list devices to get a similar result:

Try this Simple 3 Step

1. Copy the following code in didFinishLaunchingWithOptions your appdelegate.m and add a break point before the NSLog()

   (BOOL)application:(UIApplication *)application
   
   
   didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   
   
   NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
   NSLog(@"%@",[paths objectAtIndex:0]);
   }
   

Or in Swift:

let paths = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
print(paths[0])

2.Open Finder->Go -> Go to folder and paste the path copied from step 1

3. Yah!!! You are in your Destination.

Based on Michaels answers, this is for Swift 3

    func applicationDirectoryPath() -> String {
return NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).last! as String
}

After new updates of Xcode I found that the sql files are now stored in new folder /Library/Application Support this could be a unique situation but if you did not found the sql files in document folder search them here:

~/Library/Developer/CoreSimulator/Devices/[@device_id@]/data/Containers/Data/Application/[@application_id@]/Library/Application Support/

before it was stored in Documents folder:

~/Library/Developer/CoreSimulator/Devices/[@device_id@]/data/Containers/Data/Application/[@application_id@]/Documents/

For Swift 3.0

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
print(paths[0])

you can get location of Coredata in Xcode 8.2

For swift 3

print(NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory, .userDomainMask, true).last! as String)

For SWIFT 3 :

Copy paste this code in didFinishLaunchingWithOptions

 print(NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory, .userDomainMask, true).last! as String)

For iOS 10.0+ you can use persistentContainer.persistentStoreCoordinator.persistentStores.first?.url

I have created the Utility function that copies the sqlite file to your desired location (works only for simulator).

You can use it like

import CoreData




let appDelegate = UIApplication.shared.delegate as! AppDelegate
UTility.getSqliteTo(destinationPath: "/Users/inderkumarrathore/Desktop", persistentContainer: appDelegate.persistentContainer)

If you've already access to sqlite, shm and wal files then run the commands in the terminal to merge the WAL file into the sqlite file.

$ sqlite3 persistentStore
sqlite> PRAGMA wal_checkpoint;
Press control + d

After running the above commands you can see the data in your sqlite file.

Here is definition of utility method for swift

/**
Copies the sqlite, wal and shm file to the destination folder. Don't forget to merge the wal file using the commands printed int the console.
@param destinationPath Path where sqlite files has to be copied
@param persistentContainer NSPersistentContainer
*/
public static func getSqliteTo(destinationPath: String, persistentContainer: NSPersistentContainer) {
let storeUrl = persistentContainer.persistentStoreCoordinator.persistentStores.first?.url


let sqliteFileName = storeUrl!.lastPathComponent
let walFileName = sqliteFileName + "-wal"
let shmFileName = sqliteFileName + "-shm"
//Add all file names in array
let fileArray = [sqliteFileName, walFileName, shmFileName]


let storeDir = storeUrl!.deletingLastPathComponent()


// Destination dir url, make sure file don't exists in that folder
let destDir = URL(fileURLWithPath: destinationPath, isDirectory: true)


do {
for fileName in fileArray {
let sourceUrl = storeDir.appendingPathComponent(fileName, isDirectory: false)
let destUrl = destDir.appendingPathComponent(fileName, isDirectory: false)
try FileManager.default.copyItem(at: sourceUrl, to: destUrl)
print("File: \(fileName) copied to path: \(destUrl.path)")
}
}
catch {
print("\(error)")
}
print("\n\n\n ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ NOTE ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~\n")
print("In your terminal run the following commands to merge wal file. Otherwise you may see partial or no data in \(sqliteFileName) file")
print("\n-------------------------------------------------")
print("$ cd \(destDir.path)")
print("$ sqlite3 \(sqliteFileName)")
print("sqlite> PRAGMA wal_checkpoint;")
print("-------------------------------------------------\n")
print("Press control + d")
}

For objective-c

/**
Copies the sqlite, wal and shm file to the destination folder. Don't forget to merge the wal file using the commands printed int the console.
@param destinationPath Path where sqlite files has to be copied
@param persistentContainer NSPersistentContainer
*/
+ (void)copySqliteFileToDestination:(NSString *)destinationPath persistentContainer:(NSPersistentContainer *)persistentContainer {
NSError *error = nil;
NSURL *storeUrl = persistentContainer.persistentStoreCoordinator.persistentStores.firstObject.URL;
NSString * sqliteFileName = [storeUrl lastPathComponent];
NSString *walFileName = [sqliteFileName stringByAppendingString:@"-wal"];
NSString *shmFileName = [sqliteFileName stringByAppendingString:@"-shm"];
//Add all file names in array
NSArray *fileArray = @[sqliteFileName, walFileName, shmFileName];


// Store Directory
NSURL *storeDir = storeUrl.URLByDeletingLastPathComponent;


// Destination dir url, make sure file don't exists in that folder
NSURL *destDir = [NSURL fileURLWithPath:destinationPath isDirectory:YES];


for (NSString *fileName in fileArray) {
NSURL *sourceUrl = [storeDir URLByAppendingPathComponent:fileName isDirectory:NO];
NSURL *destUrl = [destDir URLByAppendingPathComponent:fileName isDirectory:NO];
[[NSFileManager defaultManager] copyItemAtURL:sourceUrl toURL:destUrl error:&error];
if (!error) {
RLog(@"File: %@ copied to path: %@", fileName, [destUrl path]);
}
}




NSLog(@"\n\n\n ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ NOTE ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~\n");
NSLog(@"In your terminal run the following commands to merge wal file. Otherwise you may see partial or no data in %@ file", sqliteFileName);
NSLog(@"\n-------------------------------------------------");
NSLog(@"$ cd %@", destDir.path);
NSLog(@"$ sqlite3 %@", sqliteFileName);
NSLog(@"sqlite> PRAGMA wal_checkpoint;");
NSLog(@"-------------------------------------------------\n");
NSLog(@"Press control + d");
}

Swift 3.x

Locate didFinishLaunchingWithOptions function in your AppDelegate file and past this code there.

let path = NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory, .userDomainMask, true)
print("\(path)")

None of the answers mentioned the simplest way to actually get the location of the DB file.

It doesn't even require you to modify your source code, as it's a simple run time switch in XCode.

1. Choose Edit Scheme... next to the Run button.

   

2. Select Run / Arguments and add the following two options:

   -com.apple.CoreData.SQLDebug 1
   -com.apple.CoreData.Logging.stderr 1
   

   

3. Run the app, and you'll see in the logs:

   

If you haven't specified any directory then you can use the below code to print default directory:

print(NSPersistentContainer.defaultDirectoryURL())

Swift 4.x

    let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
print(paths[0])

You can use following code.

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
**print(persistentContainer.persistentStoreDescriptions)**
return true
}

It will print location of core data persistent storage i.e sqlite

Swift 4.2

let paths = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true)
print(paths[0])

Swift 4.2

I have created an extension for the NSPersistentStoreDescription

import CoreData


extension NSPersistentStoreDescription {
func getDatabaseLocation() -> String? {
return self
.url?
.absoluteString
.replacingOccurrences(of: "file://", with: "") // Remove file suffix
.replacingOccurrences(of: "%20", with: "\\ ") // Make the spaces to support terminal paste
}
}

Then I use it when I initialize the NSPersistentContainer

lazy var persistentContainer: NSPersistentContainer = {


let container = NSPersistentContainer(name: "CoreDataDemo")
        

container.loadPersistentStores(completionHandler: { (storeDescription, error) in
            

#if DEBUG
debugPrint(storeDescription.getDatabaseLocation() ?? "No database location")
#endif
            

if let error = error as NSError? {
assertionFailure("Unresolved error \(error), \(error.userInfo)")
}
})
        

return container
}()

swift 4.x

You can reliably fetch it from your NSPersistentContainer description.

for description in container.persistentStoreDescriptions {
print("db location: \(description.url!)")
}

1. Chose the edit Scheme enter image description here

2. Select Run / Arguments and add the following two options:- Add two Aurgument

-com.apple.CoreData.SQLDebug 1 -com.apple.CoreData.Logging.stderr 1

enter image description here

1. You will get in console of XCode enter image description here

2. Click on -> Finder -> then Click GO

3. List item

4. copy and paste

5. List item
