当按下按钮允许全屏查看内容时,是否可以隐藏选项卡?

有一种内置的方法可以做到这一点:

self.hidesBottomBarWhenPushed = YES;

但在视图被推送之前,您必须这样做。以下是您可能希望使用的方式:

ChildViewController* childVC = [[ChildViewController alloc] init];
childVC.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:childVC animated:YES];
[childVC release];

我发现的最佳解决方法是更改视图大小,使其覆盖选项卡。以下是选择行时隐藏状态栏、导航栏和选项卡栏的代码:

- (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];
}   
}

我的解决方案:

// Hide tab bar animated
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionFade];
[[self.view.window layer] addAnimation:animation forKey:@"layerAnimation"]; 
[self.tabBarController.tabBar setHidden:YES];

// Display tab bar animated
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionFade];
[[self.view.window layer] addAnimation:animation forKey:@"layerAnimation"]; 
[self.tabBarController.tabBar setHidden:NO];

你必须增加 #import <QuartzCore/QuartzCore.h>

我找到了这个问题的一个答案,非常简单有效。

解决方案是设置选项 “按下时隐藏下栏” 在所有视图中,查看应用程序的控制器和选项卡栏控制器。

您可以在ib中或者通过代码来实现这一点。

希望这能帮助大家…

为了调整窗口的大小,首先需要在Inspector窗口的“属性”选项卡下的状态栏字段中选择“无”选项。然后,Interface Builder将允许您更改窗口的大小。

以防任何人需要单触式操作系统这个很酷的小把戏。(谢谢!)
