学习表视图（Table View）的应用时，自己写了个demo，最后表格出来了，可是滑动时报错了,报错如下：

这是我ViewController.m部分的代码：

 #import "ViewController.h"

 @interface ViewController ()

 @end

 @implementation ViewController

 {

     NSArray *tableData;

 }

 - (void)viewDidLoad

 {

     [super viewDidLoad];

     // Do any additional setup after loading the view, typically from a nib.

     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" , @"green tea" , @"thai shrimp cake" , @"angry birds cake" , @"ham and cheese panini" , nil];

     //[tableData retain];

 }

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

 {

     return [tableData count];

 }

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

 {

     static NSString *simpleTableIdentifier = @"SimpleTableItem";

     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

     if (cell == nil) {

         cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];

     }

     //[[cell textLabel] setText:[tableData objectAtIndex:[indexPath row]]];

     cell.textLabel.text = [tableData objectAtIndex:indexPath.row];

     cell.imageView.image = [UIImage imageNamed:@"icon.png"];

     return cell;

 }

 - (void)didReceiveMemoryWarning

 {

     [super didReceiveMemoryWarning];

     // Dispose of any resources that can be recreated.

 }

 @end
