svprogresshud not showing in xcode5 ios7 - objective-c

Question

I am trying to use SVProgressHUD with cocoapods. I have install it in my xcode workspace following numerous tutorials online. It seems simple enough to use, but I cannot get it to work. Here my code to load data from rottentomatoes app. I want to show "loading" while the network request is doing its thing. I am wondering if this is ui thread issue ? I added a sleep inside the network request because the results were coming back too fast !
- (void) reload{
[SVProgressHUD showWithStatus:#"Updating" maskType:SVProgressHUDMaskTypeBlack];
NSString *url = #"http://api.rottentomatoes.com/api/public/v1.0/lists/dvds/top_rentals.json?";
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
[NSThread sleepForTimeInterval:3];
NSDictionary *object = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSMutableArray *array = [[NSMutableArray alloc]initWithArray:[object objectForKey:#"movies"]];
self.movies = [[NSMutableArray alloc]init];
for(NSDictionary *item in array){
SFMovie *movie = [[SFMovie alloc]initWithDictionary:item];
[self.movies addObject:movie];
}
[SVProgressHUD dismiss];
[self.tableView reloadData];
}];
}
EDIT for comment:
The reload is called on both init methods (since I am using storyboard for this project)
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
[self reload];
}
return self;
}
- (id) initWithCoder:(NSCoder *)aDecoder{
self = [super initWithCoder:aDecoder];
if(self){
[self reload];
}
return self;
}
Second EDIT:
I added a pull down to refresh and the "updating ..." shows up when I pull the tableview down. But it does not show up on init.
- (void)viewDidLoad
{
[super viewDidLoad];
UIRefreshControl *refreshControl = [UIRefreshControl new];
[refreshControl addTarget:self action:#selector(refresh:) forControlEvents:UIControlEventValueChanged];
refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:#"Pull to refresh..."];
self.refreshControl = refreshControl;
}
- (void)refresh:(UIRefreshControl *)sender{
[self reload];
[sender endRefreshing];
}
So I guess I cannot run UI stuff on init methods as the view is not ready. I am now calling the reload method on viewdidload and it works file. Thank you John !

In any init methods, messing with the view hierarchy is tricky business -- keep that logic in viewDidLoad to avoid any of those modifications from being wiped (especially from storyboard initialization).
