Loading an Image with AFNetworking 2.0 - ios

Question

I'm trying to add a photo to a POST using the AFNetworking 2.0.
This ios App sends a post an a photo to a blog.
I can'f figure out why the images don't load.
Here is what I got so far:
// publish text and image
-(void)publishTextAndImage:(NSString*)resultDisplay and:(NSString*)subject with:(NSString*)nonce
{
imageData = UIImageJPEGRepresentation(selectedImage, 0.7); // create a data object from selected image
NSString *myUUID = [[NSUUID UUID] UUIDString]; // create a UUID
NSString *formatString = [NSString stringWithFormat:#"<img src=\"/wp-content/uploads/%#\"/>",myUUID];
NSString *contentString = [formatString stringByAppendingString:resultDisplay];
NSString *moodString = [NSString stringWithFormat:#"%d",self.moodNumber];
NSDictionary *parameters = #{#"title":subject,
#"content":contentString,
#"status":#"publish",
#"author":#"wordpress",
#"user_password":#"xrayyankee",
#"nonce":nonce,
#"categories":moodString,
#"attachment":#"image/jpeg"};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:#"http://thrills.it/?json=posts/create_post"
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
if (selectedImage)
{
[formData appendPartWithFileData:imageData name:#"photo" fileName:myUUID mimeType:#"image/jpeg"];
}
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
}
Thanks a bunch

Answer 1

I use the AFNetworking in this way :
AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:#"http://thrills.it/?json=posts"]];
NSURLRequest *request = [client multipartFormRequestWithMethod:#"POST" path:#"create_post" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
if (selectedImage)
{
[formData appendPartWithFileData:imageData name:#"photo" fileName:myUUID mimeType:#"image/jpeg"];
}
} ];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(#"Error: %#", error);
}];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
float progressValue = (float)((double)totalBytesWritten/(double)totalBytesExpectedToWrite);
NSLog(#"%f", progressValue);
}];
[self.queue addOperation:operation];
.
#property (nonatomic, strong) NSOperationQueue *queue;
My client is created earlier but it's created like that.
I hope that will help.

I got it, the code was fine it was an issue with the naming of the parameters, here it is:
// publish text and image
-(void)publishTextAndImage:(NSString*)resultDisplay and:(NSString*)subject with: (NSString*)nonce
{
imageData = UIImageJPEGRepresentation(selectedImage, 0.7); // create a data object from selected image
NSString *myUUID = [[NSUUID UUID] UUIDString]; // create a UUID
NSString *formatString = [NSString stringWithFormat:#"<img src=\"/wp- content/uploads/%#\"/>",myUUID];
NSString *contentString = [formatString stringByAppendingString:resultDisplay];
NSString *moodString = [NSString stringWithFormat:#"%d",self.moodNumber];
NSDictionary *parameters = #{#"title":subject,
#"content":contentString,
#"status":#"publish",
#"author":#"wordpress",
#"user_password":#"xrayyankee",
#"nonce":nonce,
#"categories":moodString};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:#"http://thrills.it/?json=posts/create_post"
parameters:parameters
constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
if (selectedImage)
{
[formData appendPartWithFileData:imageData name:#"attachment" fileName:myUUID mimeType:#"image/jpeg"];
}
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
so basically I removed the "attachment" parameter from the parameters dictionary and changed the name of the appended imageData to #"attachment". it was an issue of wordpress json api being very picky (:
