Question

ok,我找不到国际会计师联合会提出的新观点的方法。

i have an app based on UINavigationController. Once i come to a view showing details of the object, i have 1 toolBar at the bottom so i can give some options to user. When he press on barButtomItem, i want to show a new view but not changing the navigationbar, so if i press back button he goes back from detail view and not from new option.

i 知道推进的方法观点主计长,但并不按需要行事。

thx in advance!

edit: just to be a more bit more clear if i call [[self navigationController]pushViewController:loteCompraViewController animated:YES]; i get a new view, related to the new controller but it also changes the navigationbar and that is not good for me.

您对“显示物体详细情况的概览”两种方法的看法控制员:isShowingOverlayView和dismissOverlayView。在isShowingOverlayView中,如果你重新表示“新观点”,将YES退回,因为“他关于ButtomItem的新闻”。在<编码>dismissOverlayView中,隐藏着“新观点”。

然后,使你自己成为UINavigation子类主计长。您的子流层中压倒性popViewController Animated:使用您的物体尾目观测控制器的这些方法,如:

- (UIViewController *)popViewControllerAnimated:(BOOL)animated
{
    if ([self.topViewController respondsToSelector:@selector(isShowingOverlayView)]
        && [(id)self.topViewController isShowingOverlayView])
    {
        [(id)self.topViewController dismissOverlayView];
        return nil;
    } else {
        return [super popViewControllerAnimated:YES];
    }
}

Use this subclass instead of the standard UINavigationController.
