Device free space and sandbox space used

Question

I'm trying to get the free space on the device and the amount of space my sandbox is using. Any thoughts?

Thanks, Rick

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 your app is using read this question: Calculate the size of a folder
