這個(gè)方法不常用,容易被忽略,但是用起來(lái)還是蠻方便的

@implementation HMAdViewController

- (void)viewDidLoad

{

? ? [super viewDidLoad];

?? ?

? ? // 1.背景圖片

? ? UIImageView *bg = [[UIImageView alloc] init];

? ? bg.image = [UIImage imageNamed:@"Default"];

? ? bg.frame = self.view.bounds;

? ? [self.view addSubview:bg];

?? ?

? ? // 2.廣告圖片(真實(shí)的廣告圖片應(yīng)該要先下載廣告圖片)

? ? UIImageView *ad = [[UIImageView alloc] init];

? ? ad.image = [UIImage imageNamed:@"ad"];

? ? ad.width = 280;

? ? ad.height = 300;

? ? ad.centerX = self.view.width * 0.5;

? ? ad.y = 60;

? ? [self.view addSubview:ad];

?? ?

? ? // 3.2s后調(diào)到下一個(gè)主界面

? ? dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

? ? ? ? UIWindow *window = [UIApplication sharedApplication].keyWindow;

? ? ? ? UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

? ? ? ? window.rootViewController = [storyboard instantiateViewControllerWithIdentifier:@"Main"];

? ? });

}

?

@end

?

從storyBoard的里面加載控制器的方法
