Fetching Image from Parse class - uitableview

Question

Beginner here guys. I already managed to get the text from Parse class to table view. In the same class i have another column where I put the associated image file and somehow i could not get the image file. I will be glad if you can help me with this issue. Parse class name is News and the column i would like to get is imageFile. Here is my code.
.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;
#end
.m file
#import "ViewController.h"
#import "TableCell.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize newsTable;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self performSelector: #selector(retreiveFromParse)];
}
- (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 {
return events.count;
}
//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"];
return cell;
}
//user selects folder to add tag to
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"cell tapped");
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
My Cell.h
#import <UIKit/UIKit.h>
#import <Parse/Parse.h>
#interface TableCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;
#end
My cell.m
#import "TableCell.h"
#implementation TableCell
#synthesize TitleLabel;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
#end

Answer 1

Just after
PFObject *tempObject = [events objectAtIndex:indexPath.row];
cell.TitleLabel.text = [tempObject objectForKey:#"Event"];
Write below lines..
PFFile *imageFile = [tempObject objectForKey:#"image"];
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;
}
}];
This might get you going.

Answer 2

This will fetch the associated file and put it in cell.imageView, which is a PFImageView (the Parse edition of UIImageView):
PFObject *tempObject = [events objectAtIndex:indexPath.row];
cell.TitleLabel.text = [tempObject objectForKey:#"Event"];
PFFile *imageFile = [tempObject objectForKey:#"imageFile"];
if (imageFile) {
cell.imageView.file = imageFile;
[cell.imageView loadInBackground];
} else {
cell.imageView.image = [UIImage imageNamed:#"AvatarPlaceholder.png"];
}
