viewDidLoad is not called after the setting of no storyboard

Question

What I would like to do is to create UIImageView without storyboard, but failed to let it show. At first I deleted storyboard , LaunchScreen.xib and Main StoryBoard file base name from info.plist. and then what I created is as follows:

AppDelegate.h

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.backgroundColor = [UIColor greenColor];
    [self.window makeKeyAndVisible];

    return YES;
}

ViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];


    UIImage *imageData =[UIImage imageNamed:@"aaa.png"];

    UIImageView *myImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 30, 100, 100)];
    myImage.image = imageData;
    [self.view addSubview:myImage];

}

I am a beginner and couldn't find any solution. Does anybody know how to solve this? Thank you in advance.

You just need to set your window's root view controller to an instance of ViewController

self.window.rootViewController = [[ViewController alloc] init];

You'll also have to import ViewController.h at the top of your AppDelegate file
