Question

在采用新的UISplitViewController时，我尝试将更改作为使用UISplitViewControllerDisplayModeAutomatic模式时发生的默认行为。

当以纵向工作时，我希望当用户触发推送到细节侧时隐藏主要叠加层。默认情况下，覆盖图保持在屏幕上，直到用户点击详细信息一侧。

我已尝试将以下内容与代理人一起使用：

- (BOOL)splitViewController:(UISplitViewController *)splitViewController showDetailViewController:(UIViewController *)vc sender:(id)sender
{
    if (splitViewController.displayMode == UISplitViewControllerDisplayModePrimaryOverlay) {
        [UIView animateWithDuration:0.3 animations:^{
            splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
        }];
    }
    return NO;
}

这为我提供了所需的纵向行为，但这打破了横向模式（我想表现得像UISplitViewControllerDisplayModeAllVisible）。如果您已完成推动然后旋转设备，则左侧仍然是隐藏的（如预期的那样）。我无法找到一个appriprite地方来重新设置旋转时的首选模式以显示左侧（因为特征集合不能用于告诉iPad上的横向与纵向）。

如何手动触发重叠的解雇？

Dupe note： iOS8 完全改变了UISplitViewController，所以在2014年6月之前所有其他的SO答案都可能是错误的（我已经挖过许多他们，只是因为）

Answer 1

我遇到了和你一样的问题。我在Xamarin的单声道触控平台上这样做，但我认为结果会是一样的。

与LaborEtArs所说的一样，将代码移动到主视图控制器的prepareForSegue:sender:方法。然后在将模式设置为隐藏后将模式设置为自动：

if (splitViewController.displayMode == UISplitViewControllerDisplayModePrimaryOverlay) {
    splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
    splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModeAutomatic;
}

以这种方式完成后，它不再破坏横向模式。

只需将代码（不含return NO;）放在主视图控制器prepareForSegue:sender:或tableView:didSelectRowAtIndexPath:方法中。它完美无缺！

除了LaborEtArs在prepareForSegue:sender:或tableView:didSelectRowAtIndexPath:中制作动画的建议外，如果您的应用通常将splitViewController:preferredDisplayMode设置为UISplitViewControllerDisplayModeAutomatic，则只需使用animateWithDuration:方法和完成处理程序在动画后恢复displayMode：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([[segue identifier] isEqualToString:@"showDetail"]) {

        // configure the detail controller

        if (self.splitViewController.displayMode == UISplitViewControllerDisplayModePrimaryOverlay) {
            [UIView animateWithDuration:0.3 animations:^{
                self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
            } completion:^(BOOL finished){
                self.splitViewController.preferredDisplayMode = UISplitViewControllerDisplayModeAutomatic;
        }];
    }
}

使用拆分视图委托可以轻松实现，如下所示：

@interface AppDelegate ()
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
@property (nonatomic, assign) UIPopoverController *splitPopoverController;
#pragma clang diagnostic pop
@end

@implementation AppDelegate

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
- (void)splitViewController:(UISplitViewController *)splitViewController popoverController:(UIPopoverController *)popoverController willPresentViewController:(UIViewController *)vc{
#pragma clang diagnostic pop
    self.splitPopoverController = popoverController;
}

- (BOOL)splitViewController:(UISplitViewController *)splitViewController showDetailViewController:(UIViewController *)vc sender:(nullable id)sender{
    [self.splitPopoverController dismissPopoverAnimated:YES];
    return NO;
}

@end

这是Swift版本：

if (self.splitViewController?.displayMode == UISplitViewControllerDisplayMode.PrimaryOverlay){
    splitViewController?.preferredDisplayMode = UISplitViewControllerDisplayMode.PrimaryHidden
    splitViewController?.preferredDisplayMode = UISplitViewControllerDisplayMode.Automatic
} else {
    println(self.splitViewController?.displayMode)
}

放在prepareForSegue

中

@implementation SplitProductView

- (void)viewDidLoad {
    [super viewDidLoad];
    self.delegate = self;

}


- (void)viewWillAppear:(BOOL)animated{
    [self resetSplit:[[UIApplication sharedApplication] statusBarOrientation]];

    [super viewWillAppear:animated];
}

-(void)resetSplit :(UIInterfaceOrientation)toInterfaceOrientation {

    //TODOX:iphone
    if (isPad)
    {
        if(UIInterfaceOrientationIsPortrait(toInterfaceOrientation)){
            self.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryOverlay;
        }
        else{
            //if (self.displayMode == UISplitViewControllerDisplayModePrimaryOverlay)
            {
                self.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
                self.preferredDisplayMode = UISplitViewControllerDisplayModeAllVisible;
                self.preferredDisplayMode = UISplitViewControllerDisplayModeAutomatic;

            }
        }
    }
}

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
    if (isPad)
    {
        if (!UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation])){
            self.preferredDisplayMode =UISplitViewControllerDisplayModePrimaryOverlay;
        }
    }

    [self resetSplit:toInterfaceOrientation];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


- (BOOL)splitViewController:(UISplitViewController *)splitViewController
collapseSecondaryViewController:(UIViewController *)secondaryViewController
  ontoPrimaryViewController:(UIViewController *)primaryViewController {
    return YES;
}

隐藏UISplitViewController叠加在纵向
