ios – 使用AFNetworking 2.0加载图像

我正在尝试使用AFNetworking 2.0将照片添加到POST.
此ios应用程序将一张照片发送到博客.
我无法弄清楚图像无法加载的原因.

这是我到目前为止所得到的：

// 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);
 }];

}

谢谢你们
