Passing image from TableView to UIView - ios

Question

I have a tableView which I get the content from Parse.com (an image, one title and one description) and I am using a UIView for my detailView. When a cell is tapped UIView comes in with an animation. I managed to get My title and description of events but I couldn't get the Image file.
How to pass the parsed image into the UIView?
Thanks.
Here is my .h file
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#import "TableCell.h"
#interface ViewController : UIViewController <UITableViewDelegate> {
NSArray *events;
}
#property (weak, nonatomic) IBOutlet UITableView *newsTable;
#property (strong, nonatomic) IBOutlet UIView *detailView;
#property (strong, nonatomic) IBOutlet UILabel *InfoDetailLabel;
- (IBAction)backBtn:(id)sender;
#property (strong, nonatomic) IBOutlet UILabel *viewTitle;
Here is the .m file
#import "ViewController.h"
#import "TableCell.h"
#import "Reachability.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize newsTable;
- (BOOL)connected
{
Reachability *reachability = [Reachability reachabilityForInternetConnection];
NetworkStatus networkStatus = [reachability currentReachabilityStatus];
return !(networkStatus == NotReachable);
}
- (void)viewDidLoad
{
[super viewDidLoad];
//Pull to refresh
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:#selector(refresh:) forControlEvents:UIControlEventValueChanged];
[self.newsTable addSubview:refreshControl];
//Checking connection
if (![self connected])
{
// not connected
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Internet Connection Not Found" message:#"Please check your network settings!" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert show];
} else
{
// connected, do some internet stuff
}
// Do any additional setup after loading the view, typically from a nib.
[self performSelector: #selector(retreiveFromParse)];
}
//pull to refresh
- (void)refresh:(UIRefreshControl *)refreshControl {
[refreshControl endRefreshing];
}
- (void) retreiveFromParse {
PFQuery *retrieveEvents = [PFQuery queryWithClassName:#"News"];
[retrieveEvents findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
events = [[NSArray alloc] initWithArray:objects];
}
[newsTable reloadData];
}];
}
//*********************Setup table of folder names ************************
//get number of sections in tableview
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
//get number of rows by counting number of folders
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

}
//setup cells in tableView
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//setup cell
static NSString *CellIdentifier = #"EventCell";
TableCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
PFObject *tempObject = [events objectAtIndex:indexPath.row];
cell.TitleLabel.text = [tempObject objectForKey:#"Event"];
cell.DescriptionLabel.text = [tempObject objectForKey:#"Description"];
// To get the image file from Parse class
PFFile *imageFile = [tempObject objectForKey:#"imageFile"];
PFImageView *imageView = [[PFImageView alloc] init];
imageView.file = imageFile;
[imageView loadInBackground:^(UIImage *img,NSError *error){
if(!error)
{
UIImageView *yourImageView = [[UIImageView alloc] init];
yourImageView.image = imageView.image;
/*OR*/
cell.imageView.image = imageView.image;
}}];
return cell;
}
//user selects folder to add tag to
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"cell tapped");
//For detail view
PFObject *tempObject = [ events objectAtIndex:indexPath.row];
NSLog(#"%#", tempObject.objectId);
_InfoDetailLabel.text = [tempObject objectForKey:#"detailinformation"];
[self animateDetailView];
_viewTitle.text = [tempObject objectForKey:#"Event"];
[self animateDetailView];
}
//for animation of detailview
- (void) animateDetailView {
[UIView animateWithDuration:0.3 animations:^{
_detailView.frame = CGRectMake(0, 0, 320, 518);
}];
}
//back button with animation
- (IBAction)backBtn:(id)sender {

}];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
and my cell .h
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#interface TableCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;
#property (strong, nonatomic) IBOutlet UILabel *DescriptionLabel;
#property (strong, nonatomic) IBOutlet PFImageView *imageView;
#end

Answer 1

Try,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"cell tapped");
//Assuming not reordering the cells after it loaded
TableCell *cell = (TableCell *)[tableView cellForRowAtIndexPath:indexPath];
[[yourDetailView imageView] setImage:[[cell imageView] image]];
.....
}
or you can use the same method loadInBackground: used in cellForRow in detailView also
