NSMutableDictionary *selectedDict = [NSMutableDictionary new]; 
    [selectedDict setObject:editedLineItem forKey:@"Text"]; 
    [selectedDict setObject:@"fa-check" forKey:@"IconClass"]; 
    NSMutableArray *tagListDictionary = [NSMutableArray new]; 
    [tagListDictionary addObject:selectedTagsArray]; 
    LineItemsStorage *linestorage = [LineItemsStorage sharedManager]; 
    if(![linestorage.packagesArray valueForKey:@"Id"])

Verwenden Sie diesen Code

NSMutableDictionary *selectedDict = [[NSMutableDictionary new]mutableCopy]; 
    [selectedDict setObject:editedLineItem forKey:@"Text"]; 
    [selectedDict setObject:@"fa-check" forKey:@"IconClass"]; 
    NSMutableArray *tagListDictionary = [[NSMutableArray new]mutableCopy]; 
    [tagListDictionary addObject:selectedTagsArray]; 
    LineItemsStorage *linestorage = [LineItemsStorage sharedManager]; 
    if(![linestorage.packagesArray valueForKey:@"Id"]) 
    { 
     [linestorage.selectedLineItemsAndTagsArray addObject:selectedDict]; 
    } 
    else{  [[linestorage.packagesArray valueForKey:@"LineItems"]addObject:[NSMutableArray arrayWithObject:selectedDict]]; 
    }
