Hello, iOS fellows;
\nHope life is as bright as the retina display of iPhone 4S<\/a>\u00a0 (:<\/p>\n

Well, its a Valentine’s night and I’m writing this blog post at mid night, thinking that may be someone get some benefit with these few lines and saved his\/her time to googling here and there; Ahh what a priorities of an engineer? (:
\n<\/p>\n

I was working on an iOS application where I had needed to determine the available disk space on user’s device, to warn the user about storage.<\/p>\n

Here is the code I used that finds out the space in bytes:<\/p>\n

[code]<\/p>\n

+(void)calculateSpaceOnDisk {
\n NSError *error = nil;
\n NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
\n NSDictionary *dictionary = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[paths lastObject] error: &amp;error];
\n if (dictionary) {
\n float freeSpace = [[dictionary objectForKey: NSFileSystemFreeSize] floatValue];
\n float totalSpace = [[dictionary objectForKey: NSFileSystemSize] floatValue];
\n } else {
\n NSLog(@&quot;Error Obtaining File System Info: Domain = %@, Code = %@&quot;, [error domain], [error code]);
\n }
\n}\/\/end calculateSpaceOnDisk:<\/p>\n

[\/code]<\/p>\n

The highlighted lines are soul of this post.<\/p>\n

Note that I’m storing all of my application’s data in Library\/Cache<\/em><\/strong> directory, not in \/Document<\/strong>;<\/em> Not sure right now how it may affect the above piece of code;<\/p>\n

Stay bright;<\/p>\n
