I tried the following :
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"export.csv"];
if ([records writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:&error] == NO) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Export error" message:@"An error occured while writing the file."
delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
[alert release];
static NSString *email = @"[email protected]";
NSString *outMailtoPath = [NSString stringWithFormat:@"mailto:%@?subject=Review&body=%@&attachment=%@", email, @"test", path, nil];
NSURL *url = [NSURL URLWithString: [(NSString *)CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)outMailtoPath,NULL,NULL,kCFStringEncodingUTF8) autorelease]];
[[UIApplication sharedApplication] openURL:url]
