ipad - 如何在 ipad 的 UiSplitviewcontroller 中隐藏主视图

Question

有没有办法以编程方式隐藏 splitviewcontroller 中的主视图。在我的应用程序中，第一个屏幕将是 splitviewcontroller，下一个屏幕我不需要任何拆分视图。我怎么能做到这一点

Answer 1

in SDK 5.0 they added new method for UISplitViewControllerDelegate that would do this easily for you. Just implement it like next and you would not see the master view:

- (BOOL)splitViewController:(UISplitViewController*)svc 
   shouldHideViewController:(UIViewController *)vc 
              inOrientation:(UIInterfaceOrientation)orientation 
{
    return YES;
}

The only place when you can see it is rotation - the part of master view is visible during animation. I've fixed that in simple way, just loaded empty and black view in master.

PS: not sure whether this is actual for i0707. But hope this could be useful for other people that now have the same issues.

与杰克的回答相同，但只有一条线。过去进入 - (void)setDetailItem:(id)newDetailItem { ... } 以解雇主人。

[[UIApplication sharedApplication] sendAction: self.navigationItem.leftBarButtonItem.action
                                           to: self.navigationItem.leftBarButtonItem.target
                                         from: nil
                                     forEvent: nil];

SplitViewController 提供的 BarButtonItem 是以编程方式隐藏 Master View Controller 的关键。

这段代码很危险！但优雅:)

导入objective c消息库

#import <objc/message.h>

接下来，获取 SplitViewController 提供的 UIBarButtonItem 的句柄

- (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem
           forPopoverController:(UIPopoverController *)popoverController
    {
        barButtonItem.title = @"Master";
        [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES];

        //Obtain handle to BarButtonItem
        [self setMasterButtonItem:barButtonItem];
    }

然后当触发事件时应该触发主视图控制器的自动关闭，即

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

你可以这样做

objc_msgSend(self.masterButtonItem.target, self.masterButtonItem.action);

Matt Gemmell 创建了一个出色的自定义 splitViewController，称为“MGSplitViewController”。它非常容易实现，注释很多，并且包含许多普通 splitViewController 所没有的优秀功能（在横向视图上隐藏主视图，在横向视图中更改拆分的位置，允许用户在运行时流畅地更改拆分的大小， ETC）。

Answer 5

但是，当我尝试时，上面的代码对我不起作用

CGRect selfFrame = self.splitViewController.view.frame; 

它做了。所以..这对我有用..（这段代码应该在你的detailviewcontroller中）

-(void)hideMaster {
    UIViewController *masterController = GetAppDelegate().masterController;

    CGRect selfFrame = self.splitViewController.view.frame; 
    CGFloat aWidth = masterController.view.frame.size.width;

    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.30f];

    if(orientation == UIDeviceOrientationLandscapeLeft)
    {
        selfFrame.size.height += aWidth;
        selfFrame.origin.y -= aWidth;
    }
    else if(orientation == UIDeviceOrientationLandscapeRight)
    {
        selfFrame.size.height += aWidth;
    }

    [self.splitViewController.view setFrame:selfFrame];

    [UIView commitAnimations];

    }

为了允许旋转，这是需要的：

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration
{
    [super willAnimateRotationToInterfaceOrientation:interfaceOrientation duration:duration]; // not sure if needed
    //By the time this method is called the bounds of the view have been changed
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationBeginsFromCurrentState:YES];

    if (UIInterfaceOrientationIsPortrait(interfaceOrientation)) {
        if (masterIsHidden) {
            [self showMaster];
        }
    } else {
        if (self.editing) {
            [self hideMaster];
        }
    }
       [UIView setAnimationDuration:duration];
    [UIView commitAnimations];
}

Answer 6

尝试这个：

splitVC.modalPresentationStyle = UIModalPresentationFullScreen;
[splitVC presentModalViewController:[[splitVC viewControllers] objectAtIndex:1] animated:NO];

对我来说适用于 4.2！

这是另一个很棒的技巧。视频链接在这里。

虽然它不会有很好的转换（抱歉），但您可以通过将根视图设置为详细视图控制器的视图来实现此目的，然后将视图与 UISplitView 交换并将详细视图移动到 UISplitView。（实际上，您可能能够为视图交换设置动画（推/翻转/等），但在视图更改动画期间更改任何内容是个坏主意，并且将详细视图移动到 UISplitView 内部可能符合条件。）

Answer 8

不知道这是不是你要找的。例如，要在单击按钮时以横向模式隐藏主视图，您可以执行以下操作（在选择器方法中）

UIViewController *master = [splitViewController.viewControllers objectAtIndex:0];
UIViewController *detail = [splitViewController.viewControllers objectAtIndex:1];

[master.view setFrame:CGRectMake(0, 0, 0, 0)];
detail.view.frame = splitViewController.view.bounds;   // or use master and detail length

Answer 9

这有效：

将“隐藏”方法附加到您的按钮，例如：

UIBarButtonItem *hideButton = [[UIBarButtonItem alloc] initWithTitle:@"hide"
                                         style: UIBarButtonItemStylePlain
                                        target: self
                                        action: @selector(hide:)
                              ];

[self.mainView.navigationItem setLeftBarButtonItem:hideButton];

在这段代码中，“self.mainView”是 splitview 的第二个视图中导航控制器中的视图控制器 - 仅作为参考。

hide 方法看起来像这样。

-(void)hide:(id)sender
{
    UIViewController *masterController = [self.viewControllers objectAtIndex:0];

    CGRect selfFrame = self.view.frame; 
    CGFloat aWidth = masterController.view.frame.size.width;

    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.30f];

    if(orientation == UIDeviceOrientationLandscapeLeft)
    {
        selfFrame.size.height += aWidth;
        selfFrame.origin.y -= aWidth;
    }
    else if(orientation == UIDeviceOrientationLandscapeRight)
    {
        selfFrame.size.height += aWidth;
    }

    [self.view setFrame:selfFrame];

    [UIView commitAnimations];

}

这是起点，显然需要做更多的逻辑来处理旋转，再次显示等等......

我希望这有帮助。
