Used space for free space and space for the sandbox

Question

I try to get free space on the device and the amount of space that my sandbox uses. Any thoughts?

Thanks Rick

Answer 1

In Objective-C, you can get the available file system space with NSFileManager:

NSFileManager* filemgr = [NSFileManager defaultManager];

NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [paths objectAtIndex:0];            

NSDictionary* fsAttr = [filemgr attributesOfFileSystemForPath:docDirectory error:NULL];

unsigned long long freeSize = [(NSNumber*)[fsAttr objectForKey:NSFileSystemFreeSize] unsignedLongLongValue];

To get the amount of space used by your application, read this question: Calculate folder size

Answer 2

it's close but not perfect.

NSFileManager a = NSFileManager.DefaultManager;
NSError _error;

string _databaseFolder = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "..");
NSDictionary _b =  a.GetFileSystemAttributes(_databaseFolder,out _error);
NSObject _d =  NSObject.FromObject("NSFileSystemFreeSize");
NSObject _c =  _b.ObjectForKey(_d);

This is a direct translation from @ phix23 to MonoTouch (sorry for the length of the lines, cocoa is too verbose):

var docDir = NSSearchPath.GetDirectories(NSSearchPathDirectory.DocumentDirectory,NSSearchPathDomain.User, true)[0];
var freeSpace = NSFileManager.DefaultManager.GetFileSystemAttributes(docDir).FreeSize;
