I am new to iOS app development. I am trying to make a table view with custom cells but i can't achieve it. The code is crashing without any error message and it says
Thread1: Program received signal Sigbart
. Please help me with it.
SimpleTableCell.h
#import <UIKit/UIKit.h>
@interface SimpleTableCell : UITableViewCell
@property (weak, nonatomic) IBOutlet UILabel *nameLabel;
@property (weak, nonatomic) IBOutlet UILabel *prepTimeLabel;
@property (weak, nonatomic) IBOutlet UIImageView *thumbNailImageView;
@end
SimpleTableCell.m
#import "SimpleTableCell.h"
@implementation SimpleTableCell
@synthesize nameLabel;
@synthesize prepTimeLabel;
@synthesize thumbNailImageView;
- (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
SimpleTableViewController.h
#import <UIKit/UIKit.h>
@interface SimpleTableViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>
@property (strong, nonatomic) IBOutlet UITableView *table;
@end
SimpleTableViewController.m
#import "SimpleTableViewController.h"
#import "SimpleTableCell.h"
@implementation SimpleTableViewController
{
NSArray *tableData;
NSArray *thumbnails;
NSArray *prepTime;
}
@synthesize table;

{
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}

{
[super viewDidLoad];
tableData = [NSArray arrayWithObjects:@"Egg Benedict", @"Mushroom Risotto", @"Full Breakfast", @"Hamburger", @"Ham and Egg Sandwich", @"Creme Brelee", @"White Chocolate Donut", @"Starbucks Coffee", @"Vegetable Curry", @"Instant Noodle with Egg", @"Noodle with BBQ Pork", @"Japanese Noodle with Pork", @"Green Tea", @"Thai Shrimp Cake", @"Angry Birds Cake", @"Ham and Cheese Panini", nil];
thumbnails = [NSArray arrayWithObjects:@"egg_benedict.jpg", @"mushroom_risotto.jpg", @"full_breakfast.jpg", @"hamburger.jpg", @"ham_and_egg_sandwich.jpg", @"creme_brelee.jpg", @"white_chocolate_donut.jpg", @"starbucks_coffee.jpg", @"vegetable_curry.jpg", @"instant_noodle_with_egg.jpg", @"noodle_with_bbq_pork.jpg", @"japanese_noodle_with_pork.jpg", @"green_tea.jpg", @"thai_shrimp_cake.jpg", @"angry_birds_cake.jpg", @"ham_and_cheese_panini.jpg", nil];

}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [tableData count];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"SimpleTableCell";
SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbNailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = [prepTime objectAtIndex:indexPath.row];
return cell;
}
- (void)viewDidUnload
{
[self setTable:nil];
[super viewDidUnload];
}
@end
Please help. Thanks

Custom cells need to be registered for reuse before calling dequeue....]
You can do this in the viewDidLoad
[self.tableView registerClass:[UITableViewCell class] forCellWithReuseIdentifier:@"CustomCell"];

You should double check all connections in Interface Builder. It look likes you have a error in connection between your cell or controller to xib files

The proble lies in the cellForRowAtIndexPath section. In which you define a cell as first object nib array. But it may not be a UITableViewCell class. So you have to check whether it is a UITableViewCell class object. Try this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"SimpleTableCell";
SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleTableCell" owner:nil options:nil];
for (id eachObject in nib) {
if ([eachObject isKindOfClass:[UITableViewCell class]]) {
cell = eachObject;
break;
}
}
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbNailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = [prepTime objectAtIndex:indexPath.row];
return cell;
}
