    <p>I am trying to to use mail api from <a href="http://sendgrid.com/docs/API_Reference/Web_API/mail.html" rel="nofollow">sendgrid.com</a> but everytime it finishes with failure block. Also I don't understand how to send the image as an attachment in the email. Can anybody tell me whats wrong in below code &amp; how can I send image ? I am using below code for now</p> <pre><code>-(void)sendEmail { NSMutableDictionary *params = [[NSMutableDictionary alloc]init]; [params setValue:@"username" forKey:@"api_user"]; [params setValue:@"sdsfddf23423" forKey:@"api_key"]; [params setValue:@"test@gmail.com" forKey:@"to"]; [params setValue:@"test user" forKey:@"toname"]; [params setValue:@"Test SendGrid" forKey:@"subject"]; [params setValue:@"Test SendGrid from iOS app" forKey:@"text"]; [params setValue:@"noreply@gmail.com" forKey:@"from"]; NSURL *url = [NSURL URLWithString:@"https://sendgrid.com/api"]; AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL: url]; NSMutableURLRequest *request = [client requestWithMethod:POST path:@"/mail.send.json" parameters:params]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil]; DLog(@"Get latest product info response : %@", response); NSLog(@"Success"); } failure: ^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Failure"); }]; [operation start]; } </code></pre> <p>Thanks in advance.</p> <p>Update </p> <p>I made some changes in code &amp; now I can send the email successfully as below</p> <pre><code>-(void)sendEmailWithoutImage { NSDictionary *parameters = @{@"api_user": @"username", @"api_key": @"sdsfddf23423", @"subject":@"Test SendGrid", @"from":@"noreply@gmail.com", @"to":@"test@gmail.com", @"text":@"Test SendGrid from iOS app"}; [[MyAPIClient sharedAPIClient] POST:@"mail.send.json" parameters:parameters success:^(NSURLSessionDataTask *task, id responseObject) { NSLog(@"Success::responseObject : %@", responseObject); } failure:^(NSURLSessionDataTask *task, NSError *error) { NSLog(@"Error::Mail response : %@", error); }]; } </code></pre> <p>But when I try to send the image as attachment then it result in 400 bad request.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
