Preparing NSArray from NSdictionary to show in next VC - ios

Question

pretty simple question.
How do i create two arrays from my NSDictionary full of Json data?
How do i then use these in my next vc and set that to the value of my cell.label.text?
Here is my current code as follows:
GroupsHomeViewController.h
// Toggle View Button (on button click open next view controller and populate table view with group matching data)
- (IBAction)ShowModels:(id)sender {
NSString *var1 = self.groupLabel.text.lowercaseString;
NSString *var3 = [var1 stringByReplacingOccurrencesOfString:#" " withString:#""]; //how to remove spaces personal reference.
NSString *var2 = self.groupLabel.text.lowercaseString;
NSString *var4 = [var2 stringByReplacingOccurrencesOfString:#" " withString:#""];
NSURLSession *session = [NSURLSession sharedSession];
// NSLog(#"%#", var3); used for testing remove upon completion.
NSURLSessionDataTask *dataTask = [session dataTaskWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://www.test.com/%#/%#.json", var3, var4]] completionHandler:^(
NSData *data,
NSURLResponse *response,
NSError *error) {
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
//need to assign #amount to a nsarray somehow and then display in next vc.
//need to also assign amake to an nsarray and send to next vc also.
NSLog(#"%#", json);
}];
//Run the completed task.
[dataTask resume];
}
ModelViewController.h
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Set number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Set number of rows.
return 0; //change to count.
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
}
//cell.textLabel.text = #amount //...need to find code for this...
//cell.detailedLabel.text = #model
// Set data for cell:
return cell;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
I would just like to know how to create the NSArray out of my dictionary i already know how to set them to my cell.label.text. Thanks for your help.
JSON format:
{
amount = 2;
make = V8;
}

Lee Sugden you can easily get the data from dictionary and you ca add the objects to array.
NSMutableArray *arrJsonAmount = [[NSMutableArray alloc]init];
NSMutableArray *arrJsonMake = [[NSMutableArray alloc]init];
[arrJsonAmount addObject:[json objectForKey:#"amount"]];
[arrJsonMake addObject:[json objectForKey:#"Make"]];
UITableView DataSource Methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [arrJsonAmount count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellID];
}
cell.textLabel.text = arrJsonAmount[indexPath.row];
cell.detailedLabel.text = arrJsonMake[indexPath.row];
return cell;
}
