Detail View from TableView, Parsing - objective-c

Question

Can someone please help me, I looked everywhere to figure this out and nothing worked so far. I need to pass some data from table view to detail view and stick it into labels and Uiimage.
Data tableview is pulling comes from Parse database I created and seems to get pulled fine into the Tableview but I would like to use the same array that tableview is using for its data to fill out the detail view.
I am using 2 columns from parse to fill out this tableview Title and sub, and another tow columns to fill out the label and image. Here is my code so far. There is a bunch of variables that i was using in this code in DetailView
.h
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#interface BooksTableViewController : UITableViewController <UITableViewDelegate,NSObject >
{
NSArray * Booksarray;
}
#property (strong, nonatomic) IBOutlet UITableView *bookstableview;
#end
.m
#import "BooksTableViewController.h"
#import "BookDetailViewController.h"
#interface BooksTableViewController ()
#end
#implementation BooksTableViewController
#synthesize bookstableview;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self performSelector:#selector(RetrieveDatafromParse)];
// Uncomment the following line to preserve selection between presentations.
// self.clearsSelectionOnViewWillAppear = NO;
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
-(void) RetrieveDatafromParse {
PFQuery * getbooks = [PFQuery queryWithClassName:#"BooksTableView"];
[getbooks findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if(!error) {
Booksarray =[[NSArray alloc] initWithArray: objects];
}
[bookstableview reloadData];
NSLog(#"%#",objects);
}];

cell.textLabel.text = [tempObject objectForKey:#"Books"];
cell.detailTextLabel.text= [tempObject objectForKey:#"Code"];
return cell;

Answer 1

Try this:
#1 create a segue from controller to controller:
#2 Give your segue an Id for example detailSegue.
#3 Perform the segue in didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self performSegueWithIdentifier:#"detailSegue" sender:sender];
}
#4 Implement the segue delegate:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if([segue.identifier isEqualToString:#"detailSegue"]){
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
BookDetailViewController *detailVC = (BookDetailViewController *)segue.destinationViewController;
detailVC.bookDesc.text=[Booksarray objectAtIndex:indexPath.row];
//I uncommented that because it looks like a typo, same value 3 times?
//detailVC.BookImage.image=[Booksarray objectAtIndex:indexPath.row];
//detailVC.bookTitle.text=[Booksarray objectAtIndex:indexPath.row];
}
}
If this is the log you get:
2014-03-21 15:06:20.151 BookStore[25539:90b]
BookIndex= { BookDetails = "Test
test"; BookImage = ""; Books = Languages; Code =
104; }
Then you need to do it like this instead:
detailVC.bookTitle.text=[[Booksarray objectAtIndex:indexPath.row]objectForKey:#"Books"];
detailVC.bookDesc.text= [[Booksarray objectAtIndex:indexPath.row]objectForKey:#"BookDetails"];
detailVC.BookImage.image=[[Booksarray objectAtIndex:indexPath.row]objectForKey:#"BookImage"];
Or to make it shorter:
NSArray *bookAtIndex = [Booksarray objectAtIndex:indexPath.row];
detailVC.bookTitle.text=[bookAtIndex objectForKey:#"Books"];
detailVC.bookDesc.text= [bookAtIndex objectForKey:#"BookDetails"];
detailVC.BookImage.image=[bookAtIndex objectForKey:#"BookImage"];
or even shorter
NSArray *bookAtIndex = Booksarray[indexPath.row];
detailVC.bookTitle.text= bookAtIndex[#"Books"];
detailVC.bookDesc.text= bookAtIndex[#"BookDetails"];
detailVC.BookImage.image= bookAtIndex[#"BookImage"];
