How to get value of multidimensional array - objective-c

Question

I have a problem when trying to retrieve values from an array.
I want to get all the values from this array in order to display them in a IUTableView.
Should I use a double for function ?
{
1 = {
dishId = 1;
dishName = "Tomato Salades";
dishPrice = 13;
dishTypeId = 1;
dishTypeName = Starter;
};
2 = {
dishId = 2;
dishName = "Leeks Salades";
dishPrice = 12;
dishTypeId = 1;
dishTypeName = Starter;
};
3 = {
dishId = 3;
dishName = Fries;
dishPrice = 14;
dishTypeId = 2;
dishTypeName = "Main Course";
};
4 = {
dishId = 4;
dishName = Beef;
dishPrice = 15;
dishTypeId = 2;
dishTypeName = "Main Course";
};
7 = {
dishId = 7;
dishName = "Cheese Cake";
dishPrice = 8;
dishTypeId = 3;
dishTypeName = Dessert;
};
menuCountry = France;
menuDescription = "un menu pas comme les autres pour une region pas comme les autres";
menuId = 1;
menuName = "Autour de l\\Alsace";
menuState = 1;
}
This is my Python code which creates a Dictionary in a Array :
def getDishOfTheWeek():
menuArray = []
menuDic = Ddict(dict)
for menu in Menus.select().where(state=True):
menuDic['menuId']=menu.id
menuDic['menuName']=menu.name
menuDic['menuCountry']=menu.country.name
menuDic['menuDescription']=menu.description
menuDic['menuState']=menu.state
for d in DishMenuRels.select().where(menu = menu.id).join(Dishes).join(DishTypes).order_by((DishTypes,'name')):
menuDic[str(d.dish.id)] = {}
menuDic[str(d.dish.id)]['dishTypeName'] = d.dish.dishType.name
menuDic[str(d.dish.id)]['dishTypeId'] = d.dish.dishType.id
menuDic[str(d.dish.id)]['dishId'] = d.dish.id
menuDic[str(d.dish.id)]['dishName'] = d.dish.name
menuDic[str(d.dish.id)]['dishPrice'] = d.dish.price
menuArray.append(menuDic)
return json.dumps(menuArray)
This is my Objectiv-C code in order to get the DataJson and put it in an Array:
- (void)stream:(NSStream *)theStream handleEvent:(NSStreamEvent)streamEvent {
switch (streamEvent) {
case NSStreamEventOpenCompleted:
[[ConnectionSingleton getInstance] setConnectionMade:YES];
NSLog(#"Stream opened");
break;
case NSStreamEventHasBytesAvailable:
if (theStream == inputStream) {
uint8_t buffer[1024];
int len;
while ([inputStream hasBytesAvailable]) {
len = [inputStream read:buffer maxLength:sizeof(buffer)];
if (len > 0) {
NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];
output = [output substringToIndex:[output length] - 2];
if (nil != output) {
NSError* error; // Obligatoir pour le JSON
menu = [NSJSONSerialization JSONObjectWithData:[output dataUsingEncoding:NSUTF8StringEncoding] options:
NSJSONReadingMutableContainers error:&error]; // Put Json in the Array
[[self tableView] reloadData]; // Reload Array to populate it
}
}
}
}
break;
case NSStreamEventErrorOccurred:
NSLog(#"Can not connect to the host!");
break;
case NSStreamEventEndEncountered:
break;
default:
NSLog(#"Unknown event");
}
}

I think this should do the trick
NSArray *firstArray = [NSArray arrayWithObjects:[NSArray arrayWithObjects:#"1",#"2",#"3",#"4",#"5",#"6",nil], [NSArray arrayWithObjects:#"1",#"2",#"3",#"4",#"5",#"6",nil],[NSArray arrayWithObjects:#"1",#"2",#"3",#"4",#"5",#"6",nil],[NSArray arrayWithObjects:#"1",#"2",#"3",#"4",#"5",#"6",nil],[NSArray arrayWithObjects:#"1",#"2",#"3",#"4",#"5",#"6",nil],#"String",#"String",#"String",#"String",#"String",nil];
NSInteger count_i = firstArray.count;
NSInteger count_j;
id val;
for (NSInteger i = 0; i < count_i; i++) {
if ([[firstArray objectAtIndex:i] isKindOfClass:[NSArray class]]) {
count_j = [[firstArray objectAtIndex:i] count];
for (NSUInteger j = 0; j < count_j; j++) {
val = [[firstArray objectAtIndex:i] objectAtIndex:j];
NSLog(#"%#",val);
}
}else{
val = [firstArray objectAtIndex:i];
NSLog(#"%#",val);
}
}
But your values are of different types, so you have to deal with them in different ways depending of the value of j.
