我正在开发一个包含多个模态视图控制器的棒球游戏应用程序。但是，当我进行从“BasicGameSetupViewController”到“BasicViewController”的模态转换时，会发生转换（因为我在 BasicViewController 的 ViewDidLoad 方法中有 NSLog 语句），但实际视图不会更新。这是我转换到 BasicViewController 的方法（此代码在 BasicGameSetupViewController 中）：

- (IBAction)pressedBeginPlay:(id)sender {
    numOfInnings = [selectInnings selectedSegmentIndex];
    numOfInnings = numOfInnings + 1;
    row = [teamSelector selectedRowInComponent:0];
    visitor = [teams objectAtIndex:row];
    row = [teamSelector selectedRowInComponent:1];
    home = [teams objectAtIndex:row];
    NSLog(@"%@", visitor);
    NSLog(@"%@", home);
    if([awaySelect selectedSegmentIndex] == 0)
    {
        awayPlayer = @"Human";
    }
    else
    {
        awayPlayer = @"CPU";
    }
    if([homeSelect selectedSegmentIndex] == 0)
    {
        homePlayer = @"Human";
    }
    else
    {
        homePlayer = @"CPU";
    }
    [self performSegueWithIdentifier:@"startBeginnerToBasic" sender:self];
}

（这个块还有一个“prepareForSegue”方法）下面是 BasicViewController 中的 viewDidLoad 方法：

- (void)viewDidLoad{
    NSLog(@"Made it to basic View controller");
    homeLineup = [[NSMutableArray alloc] initWithCapacity:9];
    visitorLineup = [[NSMutableArray alloc] initWithCapacity:9];
    batter = [[NSMutableArray alloc] initWithCapacity:22];
    homePitcher = [[NSMutableArray alloc] initWithCapacity:22];
    awayPitcher = [[NSMutableArray alloc] initWithCapacity:22];
    pitcher = [[NSMutableArray alloc] initWithCapacity:22];
    homeAlreadyPitched = [[NSMutableArray alloc]initWithCapacity:5];
    awayAlreadyPitched = [[NSMutableArray alloc] initWithCapacity:5];
    NSLog(@"arrays initialized");
    [super viewDidLoad];
    [self setUpTeams];
    [self checkForComputer];
    [self newBatter];
    [self atBat];
    // Do any additional setup after loading the view.
}

我完全不知道为什么我的观点没有显示出来。上面 ViewDidLoad 代码块中的 NSLog 语句会显示，但我无法显示视图。有没有人有任何想法？预先感谢您的帮助！
