如何在SplitView控制器中隐藏和取消隐藏Master View控制器
我有一个主详细信息视图控制器，我试图写一个方法/消息显示或隐藏主列表。 我已经按照这个几乎相同的问题的所有答案，但没有一个为我工作。 我正在开发iOS6，但即使按照解决这个问题的答案的build议，我仍然无法帮助SIG_ABRT错误。
这是我的代码：
WWFMasterViewController.h：
#import <UIKit/UIKit.h> @class WWFDetailViewController; @interface WWFMasterViewController : UITableViewController @property (strong, nonatomic) WWFDetailViewController *detailViewController; @end
WWFMasterViewController.m：
#import "WWFMasterViewController.h" #import "WWFDetailViewController.h" @interface WWFMasterViewController () @property (nonatomic,strong) NSArray * arr; @end @implementation WWFMasterViewController @synthesize arr; - (void)awakeFromNib { if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { self.clearsSelectionOnViewWillAppear = NO; self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0); } [super awakeFromNib]; } - (void)viewDidLoad { [super viewDidLoad]; arr=@[@"First",@"Second",@"Third",@"Fourth",@"Fifth"]; self.detailViewController = (WWFDetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } #pragma mark - Table View - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return arr.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath]; cell.textLabel.text = arr[indexPath.row]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { self.detailViewController.detailItem = arr[indexPath.row]; } } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([[segue identifier] isEqualToString:@"showDetail"]) { NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; [[segue destinationViewController] setDetailItem:arr[indexPath.row]]; } } @end
WWFDetailViewController.h：
#import <UIKit/UIKit.h> @interface WWFDetailViewController : UIViewController <UISplitViewControllerDelegate> @property (strong, nonatomic) id detailItem; @property (weak, nonatomic) IBOutlet UILabel *detailDescriptionLabel; @end
WWFDetailViewController.m：
#import "WWFDetailViewController.h" @interface WWFDetailViewController () @property (strong, nonatomic) UIPopoverController *masterPopoverController; - (void)configureView; @end @implementation WWFDetailViewController #pragma mark - Managing the detail item - (void)setDetailItem:(id)newDetailItem { if (_detailItem != newDetailItem) { _detailItem = newDetailItem; [self configureView]; } if (self.masterPopoverController != nil) { [self.masterPopoverController dismissPopoverAnimated:YES]; } } - (void)configureView { if (self.detailItem) { self.detailDescriptionLabel.text = [self.detailItem description]; } } - (void)viewDidLoad { [super viewDidLoad]; [self configureView]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } #pragma mark - Split view - (void)splitViewController:(UISplitViewController *)splitController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController { barButtonItem.title = NSLocalizedString(@"Master", @"Master"); [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES]; self.masterPopoverController = popoverController; } - (void)splitViewController:(UISplitViewController *)splitController willShowViewController:(UIViewController *)viewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem { [self.navigationItem setLeftBarButtonItem:nil animated:YES]; self.masterPopoverController = nil; } - (BOOL) splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation { return YES; } @end
我怎么能写这个代码的方法/消息，将显示/隐藏主列表？
TIA
Use following method to hide the split view: .h file must contain UISplitViewControllerDelegate // In split delegate - (void)hideMaster { [self.splitViewController.view setNeedsLayout]; self.splitViewController.delegate = nil; self.splitViewController.delegate = self; [self.splitViewController willRotateToInterfaceOrientation:[UIApplication sharedApplication].statusBarOrientation duration:0]; }// end hideMaster -(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation { return YES; } Use following method to show the split view: // In split delegate - (void)hideMaster { [self.splitViewController.view setNeedsLayout]; self.splitViewController.delegate = nil; self.splitViewController.delegate = self; [self.splitViewController willRotateToInterfaceOrientation:[UIApplication sharedApplication].statusBarOrientation duration:0]; }// end hideMaster -(BOOL)splitViewController:(UISplitViewController *)svc shouldHideViewController:(UIViewController *)vc inOrientation:(UIInterfaceOrientation)orientation { return NO; // Important when show the split view again }

好的，我发现如何隐藏iOS6中的主视图控制器。 这是我使用的代码：
[self.masterPopoverController dismissPopoverAnimated:YES];
而对于显示主视图控制器，我想这个function是需要presentPopoverFromBarButtonItem:permittedArrowDirections:animated:但我还没有testing过。
这段代码进入DetailViewController。
