Not sure whether I understand what you want, but you get the user's home directory with:

NSArray *docDirs = NSSearchPathForDirectoriesInDomains(
                    NSDownloadsDirectory,
                    NSUserDomainMask, YES);
NSString *doc = [docDirs objectAtIndex:0];

And then you can construct the path:

NSString *path = [NSString stringWithFormat:@"%@/x.pdf", doc];
