1. import "UIViewController+XHLoadingNavigationItemTitleView.h" to your Controller header        


2. set the Controller title in viewDidLoad method, like normal setter.       


3. you can call startAnimationTitle display loading HUD for loadDatasource.         


4. you can call stopAnimationTitle hide loading HUD for Done loadDataSource.         


Finally look the code:

- (void)loadDataSource {
    [self startAnimationTitle];
}

- (void)doneLoadDataSource {
    [self stopAnimationTitle];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [self loadDataSource];
    [self performSelector:@selector(doneLoadDataSource) withObject:nil afterDelay:3];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.title = @"Detail";
}
