Objectivec 以编程方式创建 UITableView

我在Xcode 4.6中有一个应用程序，它使用故事板.我在视图控制器类中添加了一个UITableView，该类按预期工作.然而，当我试图删除情节提要中的UITableView并以编程方式将其添加回同一个类时，我遇到了两个具体问题:

1) Although I set the UITableViewCell type to be of type subtitle, the detail label no longer appears.

2) The segue that should occur when I select a cell does not occur, and prepare segue is not even being called, indicating that no message is being sent to the table view when a cell is selected.

以下是相关代码:

@interface StatsTableViewController () <UITableViewDataSource, UITableViewDelegate>
@property (strong, nonatomic) UITableView *tableView;

@end

@implementation StatsTableViewController

-(UITableView *)makeTableView
{
    CGFloat x = 0;
    CGFloat y = 50;
    CGFloat width = self.view.frame.size.width;
    CGFloat height = self.view.frame.size.height - 50;
    CGRect tableFrame = CGRectMake(x, y, width, height);

    UITableView *tableView = [[UITableView alloc]initWithFrame:tableFrame style:UITableViewStylePlain];

    tableView.rowHeight = 45;
    tableView.sectionFooterHeight = 22;
    tableView.sectionHeaderHeight = 22;
    tableView.scrollEnabled = YES;
    tableView.showsVerticalScrollIndicator = YES;
    tableView.userInteractionEnabled = YES;
    tableView.bounces = YES;

    tableView.delegate = self;
    tableView.dataSource = self;

    return tableView;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.tableView = [self makeTableView];
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"newFriendCell"];
    [self.view addSubview:self.tableView];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"newFriendCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    if (cell == nil) 
    {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }

    Friend *friend = [self.fetchedResultsController objectAtIndexPath:indexPath];

     **//THIS DATA APPEARS**
    cell.textLabel.text = friend.name;
    cell.textLabel.font = [cell.textLabel.font fontWithSize:20];
    cell.imageView.image = [UIImage imageNamed:@"icon57x57"];

    **//THIS DATA DOES NOT APPEAR**
    cell.detailTextLabel.text = [NSString stringWithFormat:@"%i Games", friend.gameCount];
    cell.detailTextLabel.textColor = [UIColor lightGrayColor];

    return cell;
}

 -(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"detailsView" sender:self];
}

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
      //I set the segue identifier in the interface builder
     if ([segue.identifier isEqualToString:@"detailsView"])
     {

         NSLog(@"segue"); //check to see if method is called, it is NOT called upon cell touch

         NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];
         ///more code to prepare next view controller....
     }
}

为了解决这两个问题，我不确定我忘记了做什么.感谢您的帮助.
