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
