#pragma mark - email
- (void)showMailPicker
{
Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil) {

}
}else{

NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
