ios upload image with multiple parameters to server - ios

Question

I am trying to upload an image with some other variables but I failed. Please tell me where I am doing mistake. I have provided some variables at the top of the code e.g. type , copies and sizing etc . If I post these values to the server without the image parameter It posted successfully But when I try to upload the image with it then it failed. Please watch the code and tell me where I am doing wrong.
`UIImage *img = [UIImage imageNamed:#"java_url.jpg"];
NSData *data = UIImageJPEGRepresentation(img,90);
NSString *md5Hash = [self md5:[NSString stringWithFormat:#"%#",data]];

I normally use AFNetworking its best library out there for any server requests try this code bellow,
it required AFNetworking
- (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];
}
