ios - Main.storyboard 未加载

Question

我是 iOS 新手，我正在做一些我一开始就卡住的练习。我想使用如下所示的标准 Main.storyBoard:


AppDelegate.m 文件如下所示:

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

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];
    UIViewController *vc = [storyboard instantiateInitialViewController];

    // Set root view controller and make windows visible
    self.window.rootViewController = vc;
    [self.window makeKeyAndVisible];



    return YES;
}

和 ViewControler 是否有用:

@interface ViewController ()

@property UIView *viewM;

@end

@implementation ViewController

-(void) loadView
{
    CGRect bounds = [[UIScreen mainScreen] bounds];

    self.viewM = [[UIView alloc] initWithFrame: bounds];
    self.view = self.viewM;

}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"AHAHH DOTKNIETO EKRANU");
}

-(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    self.view.backgroundColor = [UIColor blueColor];
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.view.backgroundColor = [UIColor whiteColor];


    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(100, 200, 200, 50)];

    //SET TEXT FOR THIS LABEL

    label.text = @"TEXTTTTTT";
    [self.view addSubview:label];

    // Do any additional setup after loading the view, typically from a nib.
}

每次我运行这个示例时，它都会加载我的 View ，它是白色的，而不是上面的图像。它有什么不对？我正在使用 Xcode 5.1.1 版本。

在项目 - 常规页面中，您应该看到“主界面”的设置。

删除applicationDidFinishLaunching中的所有代码除了 return YES;并确保将其设置为 Main .
