APP启动图之后，淡入淡出广告页，用户可以选择跳过广告。很多APP都有类似的功能。如下图：

OC实现方法：（LBLaunchImage文件需要结合SDWebImage一起使用）
在AppDeleagte.h文件中，引入LBLaunchImage
#import "AppDelegate.h"
#import "LBLaunchImageAdView.h"
#import "TestViewController.h"

  在下边方法内实现如下代码：
  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

/* FullScreenAdType 全屏广告
 * LogoAdType 带logo的广告类似网易广告，值得注意的是启动图片必须带logo图
 * ImgUrl  图片url
 */
LBLaunchImageAdView * adView = [[LBLaunchImageAdView alloc]initWithWindow:self.window andType:FullScreenAdType andImgUrl:@"http://www.uisheji.com/wp-content/uploads/2013/04/19/app-design-uisheji-ui-icon20121_55.jpg"];

//各种回调
adView.clickBlock = ^(NSInteger tag){
    switch (tag) {
        case 1100:{
            NSLog(@"点击广告回调");
            TestViewController *vc = [[TestViewController alloc]init];
            vc.view.backgroundColor = [UIColor whiteColor];
            [self.window.rootViewController presentViewController:vc animated:YES completion:^{
                
            }];
        }
            break;
        case 1101:
            NSLog(@"点击跳过回调");
            break;
        case 1102:
            NSLog(@"倒计时完成后的回调");
            break;
        default:
            break;
    }
   
};

return YES;
}

Swift实现：

         func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        let adView = LBLaunchImageAdView(window: window, andType: 1, andImgUrl: "http://www.uisheji.com/wp-content/uploads/2013/04/19/app-design-uisheji-ui-icon20121_55.jpg")
        adView.clickBlock = { tag in
        switch tag {
        case 1100:
            print("点击广告回调")
        case 1101:
            print("点击跳过回调")
            break;
        case 1102:
            print("倒计时完成后的回调")
        default: break
        }
        
    }
    // Override point for customization after application launch.
    return true
}
