创建表视图后如何解决IOS异常

Question

创建第二个表视图控制器后，我在单击连接到此表视图的选项卡栏项时出现以下异常：

2012-09-18 10:45:33.202 testStoryboard[5792:14203] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Requesting the window of a view (<UITableViewCell: 0x6b80190; frame = (0 0; 0 0); transform = [0, 0, 0, 0, 0, 0]; alpha = 0; opaque = NO; autoresize = W; layer = (null)>) with a nil layer.

编辑：这是我的代码：

//  SecondTableViewController.m
#import "SecondTableViewController.h"
@interface SecondTableViewController ()
@end
@implementation SecondTableViewController
- (id)initWithStyle:(UITableViewStyle)style
{
     self = [super initWithStyle:style];
     if (self) {
        // Custom initialization
     }
     return self;
}
- (void)viewDidLoad
{
   [super viewDidLoad];
   //Initialize the array.
   myArray2 = [[NSMutableArray alloc] init];
   //Add items
   [myArray2 addObject:@"Iceland"];
   [myArray2 addObject:@"Greenland"];
   [myArray2 addObject:@"Switzerland"];
   [myArray2 addObject:@"Norway"];
   [myArray2 addObject:@"New Zealand"];
   [myArray2 addObject:@"Greece"];
   [myArray2 addObject:@"Rome"];
   [myArray2 addObject:@"Ireland"];
   //Set the title
   self.navigationItem.title = @"Countries";
}
- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:   (UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#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 [myArray2 count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell == nil)
    {
        cell = [UITableViewCell alloc];
    }
    cell.textLabel.text = [myArray2 objectAtIndex:indexPath.row];
    return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Navigation logic may go here. Create and push another view controller.
    /*
     <#DetailViewController#> *detailViewController = [[<#DetailViewController#> alloc] initWithNibName:@"<#Nib name#>" bundle:nil];
     // ...
     // Pass the selected object to the new view controller.
     [self.navigationController pushViewController:detailViewController animated:YES];
     */
}
@end

我是IOS的新手，有人可以让我朝着正确的方向前进吗？

你对

单元的启动还没有完成，你必须初始化单元，而不仅仅是分配它。

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