Retrieving objects from parse into table view cell - ios

Question

I have created an object and saved it to the backend named NewCar and there are 4 strings attached to which are year, make, model, horsepower I'm having troubles pulling the data from parse and placing it into my table here is a few pieces of my code.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
PFQuery *query = [PFQuery queryWithClassName:#"NewCar"];
[query whereKey:#"year" equalTo:[[PFUser currentUser] objectId]];
[query orderByAscending:#"createdAt"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error) {
} else {
self.cars = objects;
[self.tableView reloadData];
}
}];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.cars count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"garageCell";
garageCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[garageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.usernameDisplay.text = [[PFUser currentUser] objectForKey:#"username"];
//I need to display the year, make and model below here.
cell.carYearLabel.text = [[PFObject objectWithClassName:#"NewCar"] objectForKey:#"year"];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 236;
}
I am able to display the username in my custom cell, but can't figure out how to display the year, make and model values. Any help would be much appreciated.
I have been looking through the documentation in Parse and can't seem to figure it out just in case you are wondering if I tried there.
I also want to add in the code where I added the object to Parse this might help in figuring this out as well.
- (IBAction)save:(id)sender {
NSString *year = self.carYear.text;
NSString *make = self.carMake.text;
NSString *model = self.carModel.text;
NSString *horsepower = self.carHorsepower.text;
if ([year length] == 0 || [make length] == 0 || [model length] == 0 || [horsepower length] == 0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:#"You might have missed a field" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alertView show];
} else {
PFObject *newCar = [PFObject objectWithClassName:#"NewCar"];
newCar[#"year"] = year;
newCar[#"make"] = make;
newCar[#"model"] = model;
newCar[#"horsepower"] = horsepower;
[newCar saveInBackground];
[self.navigationController popToRootViewControllerAnimated:YES];
}
}

Answer 1

Okay so instead of using
cell.carYearLabel.text = [[PFObject objectWithClassName:#"NewCar"] objectForKey:#"year"];
You can use the following
cell.carYearLabel.text = [self.cars objectForKey:#"NewCar"] valueForKey:#"year"];
