TableViewController.m

  @interface TableViewController () @end @implementation TableViewController @synthesize colorsTable; - (void) retrieveFromParse { PFQuery *retrieveColors = [PFQuery queryWithClassName:@"Hracky1"]; [retrieveColors findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (!error) { colorsArray = [[NSArray alloc] initWithArray:objects]; } [colorsTable reloadData]; }]; [self.colorsTable reloadData]; [self.refreshControl endRefreshing]; } - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; [self performSelector:@selector(retrieveFromParse)]; UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init]; self.refreshControl = refreshControl; [refreshControl addTarget:self action:@selector(retrieveFromParse) forControlEvents:UIControlEventValueChanged]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } #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 colorsArray.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"colorsCell"; CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; PFObject *tempObject = [colorsArray objectAtIndex:indexPath.row]; [cell.imageview setFile: [tempObject objectForKey:@"ImageURL"]]; [cell.imageview loadInBackground]; cell.cellTitle.text = [tempObject objectForKey:@"cellTitle"]; cell.cellDescript.text = [tempObject objectForKey:@"cellDescript"]; return cell; } @end 

CustomCell.h

 #import <UIKit/UIKit.h> #import "Parse/Parse.h" @interface CustomCell : UITableViewCell @property (strong, nonatomic) IBOutlet UILabel *cellTitle; @property (strong, nonatomic) IBOutlet UILabel *cellDescript; @property (strong, nonatomic) IBOutlet PFImageView *imageview; @end 

CustomCell.m

 #import "CustomCell.h" @implementation CustomCell @synthesize cellTitle; @synthesize cellDescript; @synthesize imageview; - (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

Parse using PFImageView for display a image file(PFile). Change your UIImageView to PFImageVIew
if you have xib file, change your class.

    @property (strong, nonatomic) IBOutlet PFImageView *imageview;  

In cellForRow :

     [cell.imageview setFile: [tempObject objectForKey:@"ImageURL"]];                  
     [cell.imageview loadInBackground];
