是否可以在按下按钮时隐藏标签栏以允许全屏显示内容？

问题描述：

我在基于导航的应用程序的详细视图中有一个UITabBar。我将文本和图像存储在tableview中，并希望用户能够点击单元格以隐藏导航控制器和标签栏以全屏查看内容。

I have a UITabBar in the detail view of my navigation based application. I am storing text and images in a tableview and would like the user to be able to tap on a cell to hide the navigation controller and the tabbar for full screen viewing of the content.

我发现此代码隐藏了顶部栏，但隐藏标签栏似乎并不容易。

I found this code for hiding the top bars, but it does not seem as easy to hide the tabbar.

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];
 [self.navigationController setNavigationBarHidden:YES animated:YES];

有谁知道怎么做？

一旦视图已加载，此代码无法隐藏tabBar。

This code does not work to hide the tabBar once the view is already loaded.

  yourTabViewController.hidesBottomBarWhenPushed = YES;

这是我找到的代码。似乎仅在加载视图时才起作用，因此一旦它出现，它就不能用于隐藏标签栏。我仍然在努力做这项工作。请帮忙!!!

This is the code I found. Seems to only work when the view is loaded though, so it can't be used to hide the tabbar once it has already appeared. I'm still struggling to make this work. Please help!!!

    self.tabBarController.tabBar.hidden = YES;

我找到的最佳解决方法是更改视图大小，以便它覆盖tabbar。这是我选择行时隐藏statusBar，navBar和tabBar的代码：

The best workaround I have found is to change the view size so that it covers the tabbar. Here's my code for hiding the statusBar, navBar, and tabBar when a row is selected:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

if (appDelegate.navigationController.navigationBar.hidden == NO)
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES];
    [appDelegate.navigationController setNavigationBarHidden:YES animated:YES];

    [UIView beginAnimations:@"HideTabbar" context:nil];
    [UIView setAnimationDuration:.2];
    self.view.frame = CGRectMake(0,0,320,480);
    [UIView commitAnimations];
}
if (appDelegate.navigationController.navigationBar.hidden == YES)
{
    [[UIApplication sharedApplication] setStatusBarHidden:NO animated:YES];
    [appDelegate.navigationController setNavigationBarHidden:NO animated:YES];

    [UIView beginAnimations:@"ShowTabbar" context:nil];
    [UIView setAnimationDuration:.2];
    self.view.frame = CGRectMake(0,0,320,368);
    [UIView commitAnimations];
}   
}
