Redrawing a view in ios

Question

Is it possible to redraw the whole view.

I need it to complete my language settings. The problem is that the language only changes after the views there drawn again

Answer 1

In ARC:

- (void)setLanguage:(LanguageType)languageType
{
    _language = languageType;

    //TODO:your settings

    [_theWholeView setNeedsDisplay];
}

If that can not work , there is a very troublesome solution , it can reload the whole view.

You can code like this: In the view.h , you need creat a delegate. @protocol WholeViewDelegate

- (void)reloadData;

@end

In the view.m

- (void)setLanguage:(LanguageType)languageType
{
    _language = languageType;

    //TODO:your settings

    [_delegate reloadData];
}

In the controller you need to implement the delegate In the controller.m

- (void)reloadData
{
    if(_wholeView)
    {
        [_wholeView removeFromSuperview];
    }
    // in the wholeView init method you should refresh your data
    _wholeView = [[WholeView alloc] init];
    self.view addSubview:_wholeView
}
