Write NSData to a file?

Question

I am trying to write an nsdata to a file on my disk, I have the following code and it doesn't work, am i doing anything wrong?

Boolean result = [data writeToFile:@"/Users/aryaxt/Desktop/test2.avi" atomically:YES];

test2.avi doesn't exist, I am assuming that writeToFile would create it for me

Answer 1

Try using :

NSError *error = nil;
path=@"/Users/aryaxt/Desktop/test2.avi";
[data writeToFile:path options:NSDataWritingAtomic error:&error];
NSLog(@"Write returned error: %@", [error localizedDescription]);

That'll tell you why the write is failing.
