tableView: didSelectRowAtIndexPath: appels TTNavigator openURLAction: applyAnimated: - UITabBar et navigationItem disparaissent

Question

J'ai un projet iphone existant avec un UITabBar. Maintenant, j'ai besoin de texte stylisé et de liens vers d'autres ViewControllers dans mon application. J'essaie d'intégrer TTStyledTextLabel.

J'ai un FirstViewController: UITabelViewController avec ce tableView: didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    NSString *url; 
    if ([self.filteredQuestions count]>0) { 
     url = [NSString stringWithFormat:@"%@%d", @"tt://question/", [[self.filteredQuestions objectAtIndex:indexPath.row] id]]; 

     [[TTNavigator navigator] openURLAction:[[TTURLAction actionWithURLPath: url] applyAnimated:YES]]; 
    } else { 
     Question * q = [self.questions objectAtIndex:indexPath.row] ; 
     url = [NSString stringWithFormat:@"%@%d", @"tt://question/", [q.id intValue]]; 
    } 

    TTDPRINT(@"%@", url); 
    TTNavigator *navigator = [TTNavigator navigator]; 
    [navigator openURLAction:[[TTURLAction actionWithURLPath: url] applyAnimated:YES]]; 

} 

Ma cartographie ressemble à ceci:

TTNavigator* navigator = [TTNavigator navigator]; 
navigator.window = window; 
navigator.supportsShakeToReload = YES; 
TTURLMap* map = navigator.URLMap; 
[map from:@"*" toViewController:[TTWebController class]]; 
[map from:@"tt://question/(initWithQID:)" toViewController:[QuestionDetailViewController class]]; 

et mon QuestionDetailViewController:

@interface QuestionDetailViewController : UIViewController <UIScrollViewDelegate , QuestionDetailViewProtocol> { 
    Question *question; 

} 

@property(nonatomic,retain) Question *question; 

-(id) initWithQID:(NSString *)qid; 
-(void) goBack:(id)sender; 

@end 

Quand je frappe une cellule, q QuestionDetailViewController sera appelé - mais le n avigationBar coutume

@implementation QuestionDetailViewController 
@synthesize question; 


-(id) initWithQID:(NSString *)qid 
{ 
    if (self = [super initWithNibName:@"QuestionDetailViewController" bundle:nil]) { 
    //; 
    TTDPRINT(@"%@", qid); 

    NSManagedObjectContext *managedObjectContext = [(domainAppDelegate*)[[UIApplication sharedApplication] delegate] managedObjectContext]; 

    NSPredicate *predicate =[NSPredicate predicateWithFormat:@"id == %@", qid]; 
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Question" 
               inManagedObjectContext:managedObjectContext]; 

    NSFetchRequest *request = [[NSFetchRequest alloc] init]; 
    [request setEntity:entity]; 
    [request setPredicate:predicate]; 
    NSError *error = nil; 
    NSArray *array = [managedObjectContext executeFetchRequest:request error:&error]; 

    if (error==nil && [array count]>0) { 
     self.question = [array objectAtIndex:0]; 
     } else { 
      TTDPRINT(@"error: %@", array); 
     } 
    } 
    return self; 
} 


- (void)viewDidLoad { 
    [super viewDidLoad]; 
    [TTStyleSheet setGlobalStyleSheet:[[[TextTestStyleSheet alloc] init] autorelease]]; 

    [self.navigationController.navigationBar setTranslucent:YES]; 
    NSArray *includedLinks = [self.question.answer.text vs_extractExternalLinks]; 

    NSMutableDictionary *linksToTT = [[NSMutableDictionary alloc] init]; 
    for (NSArray *a in includedLinks) { 
     NSString *s = [a objectAtIndex:3]; 
     if ([s hasPrefix:@"/answer/"] || [s hasPrefix:@"http://domain.com/answer/"] || [s hasPrefix:@"http://www.domain.com/answer/"]) { 
      NSString *ttAdress = @"tt://question/"; 
      NSArray *adressComps = [s pathComponents]; 
      for (NSString *s in adressComps) { 
       if ([s isEqualToString:@"qid"]) { 
        ttAdress = [ttAdress stringByAppendingString:[adressComps objectAtIndex:[adressComps indexOfObject:s]+1]]; 
       } 
      } 
      [linksToTT setObject:ttAdress forKey:s]; 
     } 
    } 
    for (NSString *k in [linksToTT allKeys]) { 
     self.question.answer.text = [self.question.answer.text stringByReplacingOccurrencesOfString:k withString: [linksToTT objectForKey:k]]; 
    } 

    TTStyledTextLabel *answerText = [[[TTStyledTextLabel alloc] initWithFrame:CGRectMake(0, 0, 320, 700)] autorelease]; 
    if (![[self.question.answer.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] hasPrefix:@"<div"]) { 
     self.question.answer.text = [NSString stringWithFormat:@"%<div>%@</div>", self.question.answer.text]; 
    } 

    NSString * s = [NSString stringWithFormat:@"<div class=\"header\">%@</div>\n%@",self.question.title ,self.question.answer.text]; 

    answerText.text = [TTStyledText textFromXHTML:s lineBreaks:YES URLs:YES]; 
    answerText.contentInset = UIEdgeInsetsMake(20, 15, 20, 15); 
    [answerText sizeToFit]; 

    [self.navigationController setNavigationBarHidden:NO animated:YES]; 
    [self.view addSubview:answerText]; 
    [(UIScrollView *)self.view setContentSize:answerText.frame.size]; 
    self.view.backgroundColor = [UIColor whiteColor]; 
    [linksToTT release]; 
} 


.......

Cela fonctionne très bien, dès qu'une cellule est touchée, un QuestionDetailViewController est appelé et poussé - mais le tabBar disparaîtra, et la navigationItem - Je l'ai mis comme ceci: self.navigationItem.title =@"back to first screen"; - ne sera pas être montré. Et il apparaît juste sans animation.

Mais si j'appuie sur un lien à l'intérieur du TTStyledTextLabel, l'animation fonctionne, l'élément navigationItem sera affiché.

Comment puis-je afficher l'animation, l'élément navigationItem et le tabBar?

J'ai trouvé une solution:

Mon QuestionDetailViewController implémente le TTNavigatorDelegate.

-(BOOL)navigator:(TTNavigator *)navigator shouldOpenURL:(NSURL *)URL vaudra toujours NO, mais appellera [self.navigationController pushViewController:c animated:YES];

-(BOOL)navigator:(TTNavigator *)navigator shouldOpenURL:(NSURL *)URL { 
    NSEntityDescription *entity; 
    NSPredicate *predicate; 
    NSFetchRequest *request = [[NSFetchRequest alloc] init]; 
    if ([[URL host] isEqualToString:@"question"]) { 
     entity =[NSEntityDescription entityForName:@"Question" inManagedObjectContext:managedObjectContext]; 
     predicate = [NSPredicate predicateWithFormat:@"id == %@", [[URL path] stringByReplacingOccurrencesOfString:@"/" withString:@""]]; 

     [request setEntity:entity]; 
     [request setPredicate:predicate]; 

     NSError *error =nil; 
     NSArray *array = [managedObjectContext executeFetchRequest:request error:&error]; 
     if (error==nil && [array count] >0) { 
      QuestionDetailViewController *c = [[[QuestionDetailViewController alloc] init] autorelease]; 
      c.question = [array objectAtIndex:0]; 
      [self.navigationController pushViewController:c animated:YES]; 
     } 
    } 
    [request release]; 
    return NO; 
}

Dans votre TableViewController, ajoutez:

- (id<UITableViewDelegate>)createDelegate { 
    return self; 
} 

Ensuite, vous pouvez mettre en œuvre vos propres méthodes de didSelectRowAtIndexPath et accessoryButtonTappedForRowWithIndexPath.
