从storyBoard的里面加载控制器的方法

这个方法不常用,容易被忽略,但是用起来还是蛮方便的

@implementation HMAdViewController

- (void)viewDidLoad

{

[super viewDidLoad];

// 1.背景图片

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

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

bg.frame = self.view.bounds;

[self.view addSubview:bg];

// 2.广告图片(真实的广告图片应该要先下载广告图片)

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后调到下一个主界面

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
