实现思路:

实例化view 添加到 window上,在 view上添加广告图片,跳过按钮,再做它们的相应的点击事件处理,需要引入第三方库 SDWebImage, 切记.
妥啦,就是这么简单.来上代码.

调用代码 (三行搞定) AppDelegate.m

    //本地测试
    NSString * imageURL1 = @"AD.png";
    //本地gif测试
    NSString * imageURL2 = @"ad.gif";
    ADView * adView = [[ADView alloc] initWithWindow:self.window sizeOfADImage:1.7 showTime:6 adImageURL:imageURL];
    adView.adImageClickedBlock = ^(NSInteger num){
    
        NSLog(@"在这里执行点击图片的操作,类型参数为:%ld",(long)num);
        
    };
    
    return YES;
}
