UISplitViewController在Storyboard中隐藏/取消隐藏MasterView [英] UISplitViewController Hide/Unhide MasterView In Storyboard

问题描述

我有一个简单的iPad应用程序，带有带有tableview的MasterviewController和一个包含UIWebView的DetailViewController。然后我在我的Storyboard中拖放了一个SplitViewController，将它与我的Master和Detail控制器连接起来。在MasterViewController中，我使用以下内容：

   - （void）awakeFromNib 
 {
 self.splitViewController。代表=自我; 
} 
 
  - （BOOL）splitViewController：（UISplitViewController *）svc shouldHideViewController：（UIViewController *）vc inOrientation：（UIInterfaceOrientation）orientation 
 {
 return NO; 
} 
  

目前看起来如下：

一切都很好。 我想要做的是使用DetailViewController左上角的按钮隐藏和取消隐藏MasterViewController，就像iPad Mail应用程序一样。

<我发现了一些与此问题相关的问题，但他们并没有像我一样只是在Storyboard中拖动它并编写几行代码来创建SplitView，所以不要将其标记为重复或类似的东西。

注意：请不要建议使用MGSplitViewController或任何其他第三方库。在此先感谢。

MasterViewController嵌入在导航控制器中。虽然DetailViewController上面有一个手动添加的顶栏，因为当在SplitView中添加全部内容时，它会丢失顶部的导航栏。我所知道的是，我可以在DetailView的顶部栏上创建一个IBAction按钮，但不知道如何触发隐藏和取消隐藏功能。

解决方案

我在主视图控制器（TableController）中这样做：

  #importTableController.h
 #importViewController.h
 
 @interface TableController（）
 
 @property（强，非原子）NSArray * theData; 
 @property（强，非原子）UIViewController * detailVC; 
 
 @end 
 
 @implementation TableController 
 
 
  - （void）awakeFromNib {
 self.splitViewController.delegate = self ; 
 self.detailVC = self.splitViewController.viewControllers [1]; 
} 
 
  - （void）splitViewController：（UISplitViewController *）svc willShowViewController：（UIViewController *）aViewController invalidatingBarButtonItem：（UIBarButtonItem *）barButtonItem {
 NSMutableArray * itemArray = [self。 detailVC.toolBar.items mutableCopy]; 
 [itemArray removeObject：barButtonItem]; 
 [self.detailVC.toolBar setItems：itemArray]; 
} 
 
 
  - （void）splitViewController：（UISplitViewController *）svc willHideViewController：（UIViewController *）aViewController withBarButtonItem：（UIBarButtonItem *）barButtonItem forPopoverController：（UIPopoverController *）pc { 
 barButtonItem.title = @Master; 
 NSMutableArray * itemArray = [self.detailVC.toolBar.items mutableCopy]; 
 if（！itemArray）{
 itemArray = [NSMutableArray arrayWithObject：barButtonItem]; 
} else {
 [itemArray insertObject：barButtonItem atIndex：0]; 
} 
 [self.detailVC.toolBar setItems：itemArray]; 
} 
  

我在IB中添加了一个工具栏给细节控制器，并给了它IBOutlet，toolBar。

I have a simple iPad app with MasterviewController with a tableview and and a DetailViewController containing a UIWebView. Then i dragged and dropped a SplitViewController in my Storyboard, connected it with my Master and Detail controllers. In MasterViewController i am using the following:

- (void) awakeFromNib
{
    self.splitViewController.delegate = self;
}

- (BOOL) splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation
{
    return NO;
}

It currently looks like the following:

Everything is working great. What i want to do is to hide and unhide the MasterViewController with a button at the top left side of DetailViewController, just like the iPad Mail app.

I have found some questions related to this problem but they are not creating the SplitView as simply as i am by just dragging it in the Storyboard and writing few lines of code, So don't mark it as duplicate or something like that.

NOTE: Kindly do not suggest using MGSplitViewController or any other third party library. Thanks in advance.

The MasterViewController is embedded inside a navigation controller. While DetailViewController has a top bar manually added on it because it looses the navigation bar at top when the whole things is added in the SplitView. What i know is that i can create an IBAction button on the top bar of DetailView but dont know how to trigger the hide and unhide functionality.

解决方案

I do it like this in the master view controller (TableController):

#import "TableController.h"
#import "ViewController.h"

@interface TableController ()

@property (strong, nonatomic) NSArray * theData;
@property (strong, nonatomic) UIViewController * detailVC;

@end

@implementation TableController 


-(void)awakeFromNib {
   self.splitViewController.delegate = self;
   self.detailVC = self.splitViewController.viewControllers[1];
}

-(void)splitViewController:(UISplitViewController *)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem {
    NSMutableArray *itemArray = [self.detailVC.toolBar.items mutableCopy];
    [itemArray removeObject:barButtonItem];
    [self.detailVC.toolBar setItems:itemArray];
}


-(void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)pc {
    barButtonItem.title = @"Master";
    NSMutableArray *itemArray = [self.detailVC.toolBar.items mutableCopy];
    if (! itemArray) {
        itemArray = [NSMutableArray arrayWithObject:barButtonItem];
    }else{
        [itemArray insertObject:barButtonItem atIndex:0];
    }
    [self.detailVC.toolBar setItems:itemArray];
}

I added a tool bar in IB to the detail controller, and gave it the IBOutlet, toolBar.
