comment accéder à toute la gamme de contenu du dictionnaire

Question

J'ai mis en œuvre l'ensemble du contenu du dictionnaire les méthodes d'accès, mais il est l'accès qu'un seul contenu, s'il vous plaît aider sur ce

Voici mon fichier de données

<__NSArrayM 0x8b7a350>(
{ 
    clkDate = "Wednesday, April 11, 2012"; 
    resData =  (
       {

dans le fichier de données ci-dessus j'ai besoin d'accéder à "independentItem = 1" éléments liés

i essayées code source est

for (int i = 0; i < [self.gluClkDetailArray count]; i++) 
     { 
      NSMutableDictionary *mDict = [self.gluClkDetailArray objectAtIndex:i]; 
      { 
       NSMutableArray *mResData = [mDict objectForKey:@"resData"]; 
       NSDate *mTimestamp = [[mResData objectAtIndex:0] objectForKey:@"timestamp"]; 

       NSDateFormatter *mFormatter = [[NSDateFormatter alloc] init]; 
       [mFormatter setDateStyle:NSDateFormatterFullStyle]; 

       NSString *mClkDate = [mFormatter stringFromDate:mTimestamp]; 
       [mDict setValue:mClkDate forKey:@"clkDate"]; 

       NSString *mIndItem = [[mResData objectAtIndex:0] objectForKey:@"independentItem"]; 
       if (mIndItem.intValue == 1) 
       { 
        [mDict setValue:mIndItem forKey:@"clkIndependentItem"]; 
        [mIndpendentArray addObject:mDict]; 
       } 
       [gluClkResultArray addObject:mDict]; 

     } 

quand je mets le mResData objectAtIndex: 0 au lieu de i, l'application a planté. J'ai tableau sauvé des valeurs de dictionnaire en fonction de la séquence contre

Merci à l'avance

Answer 1

changement

NSString *mIndItem = [[mResData objectAtIndex:0] objectForKey:@"independentItem"]; 

que:

NSString *mIndItem = [[mResData objectAtIndex:1] objectForKey:@"independentItem"]; 

Le independentItem est dans le dictionnaire que dans au index 1, pas 0.

Espérons que cela aide
