obj-c AFNetworking 2.0 POST request does not work

Question

Hi want to send some data (strings and a file) to a server, by using AFNetworking 2.0. Somehow the data for the POST request (for a forumlar) ist not correct, it looks like that the encoding/serialization on the request is missing. As the server can't work with the uploaded data from me. How do I set the encoding/serialization to the request? I assume the URL Form Parameter Encoding, has to be set. The docs states ``` [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters]; ``` I tried to do that, but I cannot figure out how to do it right. With the following Xcode throughs a warning: ``` manager.requestSerializer = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:URLString parameters:parameters]; ``` /.../CameraViewController.m:105:31: Incompatible pointer types assigning to 'AFHTTPRequestSerializer *' from 'NSMutableURLRequest *' Below my sourcecode: CameraViewController.h ``` #import <UIKit/UIKit.h> @interf…

Finally it works. Was a hassle but now I am really happy... During my testing I had some problems with 'request body stream exhausted' within Wifi, what was strange.

Below the code that did the trick for me.

```
- (void)upload {

// !!! only JPG, PNG not covered! Have to cover PNG as well
    NSString *fileName = [NSString stringWithFormat:@"%ld%c%c.jpg", (long)[[NSDate date] timeIntervalSince1970], arc4random_uniform(26) + 'a', arc4random_uniform(26) + 'a'];
    // NSLog(@"FileName == %@", fileName);

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

NSDictionary *parameters = @{@"lat": @"8.444444",
                                 @"lng": @"50.44444",
                                 @"location": @"New York",
                                 @"type": @"2",
                                 @"claim": @"NYC",
                                 @"flag": @"0"};
     // BASIC AUTH (if you need):
    manager.securityPolicy.allowInvalidCertificates = YES;
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];
    [manager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"foo" password:@"bar"];
    // BASIC AUTH END

NSString *URLString = @"http://192.168.1.157/tapp/laravel/public/foobar/upload";

/// !!! only jpg, have to cover png as well
    NSData *imageData = UIImageJPEGRepresentation(self.imageView.image, 0.5); // image size ca. 50 KB
    [manager POST:URLString parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/jpeg"];
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"Success %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Failure %@, %@", error, operation.responseString);
    }];

[self dismissViewControllerAnimated:NO completion:nil];
}
```
