当我点击屏幕时,导致我导航栏(顶部栏)出现/消失,并且也位于背景图像的顶部。它的工作,但有一个问题:我突然有两个导航栏!首先,有一个后退按钮命名为“后退”,当我按下“后退”时,它会弹出一个新的导航栏,并带有名为“Vinene”的后退按钮,这是它返回的TableView的标题。这就是我想要保留的那个。我认为这个问题在DetailViewController.m或MasterViewController.m的didselectrowatindexpath中。希望有人能看到问题!不需要的双导航栏
DetailViewController.m:
@interface WinesDetailViewController()
@end
@implementation WinesDetailViewController
@synthesize wineDictionary;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.navigationController.navigationBar.translucent = YES;
self.wantsFullScreenLayout = YES;
UITapGestureRecognizer *tap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation)] autorelease];
tap.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tap];
}
- (void) hideShowNavigation
{
[self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)hidesBottomBarWhenPushed{
return TRUE;
}
@end
MasterViewController.m:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSDictionary *dictionary = [wine libraryItemAtIndex:indexPath.row];
if (winesDetailViewController == nil) {
// Init the wine detail view
winesDetailViewController = [[WinesDetailViewController alloc] init];
}
// Here you pass the dictionary
winesDetailViewController.wineDictionary = dictionary;
[self.navigationController pushViewController:winesDetailViewController animated:YES];
}
}
