iOS实现动态的开屏广告示例代码
作者：小白yige
启动图是在iOS开发过程中必不可少的一个部分，很多app在启动图之后会有一张自定义的开屏广告图，但是有的时候需要让启动图看起来就是一个广告，而且还要这个广告里面会动，iOS的启动图只能是静态的，而且固定，为了实现看起来的动画效果，只能进行伪造了。下面来一起看看
一、实现效果图
二、实现思路：
用一个固定的png图片左启动图，应该和广告视图需要进行动画的期初的位置一致，当启动图消失的时候，呈现出图片，实际遇到的困难是，因为广告图片是从网络请求加载的，当时把广告视图放在了请求数据的块里面，广告出现的时候会闪一下，放在外面就没事了。
三、实现示例
1.广告的头文件
// XBAdvertView.h // scoreCount // // Created by 王国栋 on 15/12/22. // Copyright © 2015年 xiaobai. All rights reserved. // #import <UIKit/UIKit.h> @protocol XBAdvertViewDelegate <NSObject> /** * 图片被点击的代理 */ -(void)adViewClick; @end @interface XBAdvertView : UIView @property (nonatomic,weak) id<XBAdvertViewDelegate> delegate; @property (nonatomic,strong) UIImage* adimage; @end
2.广告的m文件
//
// XBAdvertView.m
// scoreCount
