Table View滑动时报错

 

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

 

经过反复的测试后，解决办法如下：

在第17行加上：

[tableData retain];

这样就可以解决报错问题了。
