IOS 7 AFNetworking 2.0 view refresh issue - ios

Question

first I'd like to say that the issue I am having is in regards to how my own code is set, not IOS or AFNetworking.
I am going to show 1 example where a view is not refreshing immediately even though the updated JSON response object from the server is being recieved.
There are 2 views being used in the first view the button below takes the user to a second view where he can upload an image that will then be displayed in the first view.
- (IBAction)editImage:(id)sender {
UIStoryboard* storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
TDUserProfileViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"TDUserProfileImageEditViewController"];
[self.navigationController pushViewController:vc animated:YES];
}
Below is the code that uploads the new data to the server and then gets new data regarding the images's address on the server.
- (IBAction)dataSubmitToServer{
// NSLog(#"photo: %#", self.photoData);
NSString * userID = [[NSUserDefaults standardUserDefaults] objectForKey:USERID];
//make the call to the web API
NSString* command = #"setProfilePhoto";
self.params =[NSMutableDictionary dictionaryWithObjectsAndKeys:command, #"command", userID, #"userid", nil];
//////////////////
NSLog(#"%#", self.params);
self.photoName = #"newname.png";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager POST:BaseURLString parameters:self.params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:UIImageJPEGRepresentation(self.userPhoto.image, 1)
name:#"image"
fileName:self.photoName
mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", [error localizedDescription]);
[TDPublicFunctions showDefaultAlert:#"Error" body:[error description]];
}];
[self getNewProfileData];
[[NSUserDefaults standardUserDefaults] synchronize];
}
-(void)getNewProfileData{
/*start getting new data for profile pic and status message*/
NSString* command = #"displayProfileData";
NSString * userID = [[NSUserDefaults standardUserDefaults] objectForKey:USERID];
NSMutableDictionary* params =[NSMutableDictionary dictionaryWithObjectsAndKeys:command, #"command", userID,#"userid", nil];
NSLog( #"%#", params);
[SVProgressHUD showWithStatus:#"Loading..." maskType:SVProgressHUDMaskTypeBlack];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:BaseURLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
[SVProgressHUD dismiss];
if([responseObject objectForKey:#"error"])
{
[[[UIAlertView alloc] initWithTitle:#"Data Retrieval Error" message:[responseObject description] delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil] show];
}
else
{
NSString * profilePhoto = [[[responseObject objectForKey:#"result"] objectAtIndex:0] objectForKey:#"profile_picture"];
NSString * status = [[[responseObject objectForKey:#"result"] objectAtIndex:0] objectForKey:#"status"];
NSString * statusMsg = [[[responseObject objectForKey:#"result"] objectAtIndex:0] objectForKey:#"status_message"];
if(profilePhoto && ![profilePhoto isKindOfClass:[NSNull class]])
[[NSUserDefaults standardUserDefaults] setObject:profilePhoto forKey:PROFILE_PHOTO];
if(status && ![status isKindOfClass:[NSNull class]])
[[NSUserDefaults standardUserDefaults] setObject:status forKey:STATUS];
if(statusMsg && ![statusMsg isKindOfClass:[NSNull class]])
[[NSUserDefaults standardUserDefaults] setObject:statusMsg forKey:STATUS_MESSAGE];
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
//end of getting data for status message and profile pic
}
Now once this above process is over the HUD is supposed to stop and when the back button on the view is hit there should be a newly uploaded image in the first view. The code below is the last of many things that I have tried in order to get the view with the image to refresh:
-(void) viewWillAppear:(BOOL)animated
{
NSString * profPic = [[NSUserDefaults standardUserDefaults] objectForKey:PROFILE_PHOTO];
NSLog(#"profilepic: %#", profPic);
// NSString* status = [[NSUserDefaults standardUserDefaults] objectForKey:STATUS];
NSString * statusMsg = [[NSUserDefaults standardUserDefaults] objectForKey:STATUS_MESSAGE];
if(profPic)
[photo loadIconForProduct:profPic];
if(statusMsg)
statusMsgView.text = statusMsg;
//self.view=nil;
//[self viewDidLoad];
[self getFriendsList];
[photo setNeedsDisplay];
[self.view setNeedsDisplay];
}
After an image is uploaded it may work the first time an image is uploaded but it does not work if the user were to press the editImage button a second time and upload another image.
What is it that is being done wrong? Let me know if there is anything else that I can supply.
Thanks.

As I can see here, you are getting a URL back as the result of the profilePhoto. So you might as well use the AFNetworking function:
Im presuming photo is a UIImageView.
[photo setImageWithURL:[NSURL URLWithString:profPic] placeholderImage:[UIImage imageNamed:#"somePlaceholderImage"]];
