ストーリーボードも使わずに実現する

前回の内容をストリーボードも使わずに実現する。ただし、AppDelegateクラスについてはUINavigationControllerをプロパティとして使い、ViewControllerクラスについてはUITableViewControllerを継承する形式で実現してみる。

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) UINavigationController *navigationController;

@end

#import "AppDelegate.h"
#import "ViewController.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    ViewController *viewController = [[ViewController alloc] init];
    self.navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
    self.window.rootViewController = self.navigationController;

    [self.window makeKeyAndVisible];
    return YES;
}

@end

#import <UIKit/UIKit.h>

@interface ViewController : UITableViewController

@end

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSArray *teams = _leagues[indexPath.section];
    NSArray *teamPrefixes = _leaguePrefixes[indexPath.section];
    
    DetailViewController *detailViewController = [[DetailViewController alloc] init];
    [detailViewController setTitle:teams[indexPath.row]];
    [detailViewController setDetailItem:teamPrefixes[indexPath.row]];
    [self.navigationController pushViewController:detailViewController animated:YES];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.view.backgroundColor = [UIColor whiteColor];
    // I don't care orientation this time!
    UILabel *detailLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
    detailLabel.textAlignment = NSTextAlignmentCenter;
    detailLabel.backgroundColor = [UIColor clearColor];
    detailLabel.text = self.detailItem;
    [self.view addSubview:detailLabel];
    NSLog(@"self.detailItem is %@", self.detailItem);
}
