Question

in the main view i call the ViewB like this

viewB=[[ViewB alloc] initWithNib:@"ViewB" bundle:nil]
[self.View addSubview:viewB];

in viewB i call ViewC like this

viewC=[[ViewC alloc] initWithNib:@"ViewC" bundle:nil]
[self.View addSubview:viewC];

i close ViewC like this to return to viewB

[self.view removeFromSuperview];

When i close ViewC i want to run - (void)viewDidLoad in ViewB i mean i want to reload the ViewB

Answer 1

You should never call viewDidLoad directly. If you need some loading functionality that is called several times them create a method and do it there:

-(void) reloadData;

First time you call it in viewDidLoad. The next time do it when you remove your ViewC. It would be a good idea not to call [self.view removeFromSuperview]; in ViewC. Add method to ViewB:

-(void) dismissViewC {
    [viewC removeFromSuperview];
    [self reloadData];
}

and call it from ViewC.

However if you’re using view controller you can reload your data in

-(void) viewWillAppear:(BOOL) animated;
