I am writing a core data app that uses an sqlite-type persistent store and I know the tables and the data are stored somewhere on the device.
Is it possible to check how much memory Core Data is using to store objects? Maybe by checking the size of the sqlite db files?
If possible, how? I could really use your ideas

Answer 1

It depends on the xcode you are using
In ios8
It stored somewhere
/ 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
You can do by writing below method intoappDelegate.m,
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];
}
It will give you document directory url on simulator.Than go to finder Cmd+Shift+G and type this address here you can navigate to sqlite files which used by core data to store the data of your app
for Xcode 3 ,Xcode 4 and for Xcpde 5 it stores in
~/Library/Application Support/iPhone Simulator/[SDK
version]/Applications/[App GUID]/Documents
EDIT You can use following code for check the size of your sqlite db of core data.I think it will work in all cases but i am not sure and also i do not verified its acuuracy.But i think it is one way to give top level details of checking the coredata db size programmatically
-(NSUInteger)calculate{
//Check where you are making the sqlite
NSURL *url = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:#"yourPersistentStoreName"];
NSUInteger sizeOfData = [[NSData dataWithContentsOfURL:url] length];
NSLog(#"sizeOfDAta in bytes %lu",(unsigned long)sizeOfData);
return sizeOfData;
}
