啟動圖是在iOS開發(fā)過程中必不可少的一個部分，很多app在啟動圖之后會有一張自定義的開屏廣告圖，但是有的時候需要讓啟動圖看起來就是一個廣告，而且還要這個廣告里面會動，iOS的啟動圖只能是靜態(tài)的，而且固定，為了實現(xiàn)看起來的動畫效果，只能進(jìn)行偽造了。下面來一起看看

一、實現(xiàn)效果圖

二、實現(xiàn)思路：

用一個固定的png圖片左啟動圖，應(yīng)該和廣告視圖需要進(jìn)行動畫的期初的位置一致，當(dāng)啟動圖消失的時候，呈現(xiàn)出圖片，實際遇到的困難是，因為廣告圖片是從網(wǎng)絡(luò)請求加載的，當(dāng)時把廣告視圖放在了請求數(shù)據(jù)的塊里面，廣告出現(xiàn)的時候會閃一下，放在外面就沒事了。

三、實現(xiàn)示例

1.廣告的頭文件

// XBAdvertView.h 
// scoreCount 
// 
// Created by 王國棟 on 15/12/22. 
// Copyright © 2015年 xiaobai. All rights reserved. 
// 
 
#import <UIKit/UIKit.h> 
@protocol XBAdvertViewDelegate <NSObject> 
/** 
 * 圖片被點擊的代理 
 */ 
-(void)adViewClick; 
@end 
@interface XBAdvertView : UIView 
 
 
@property (nonatomic,weak) id<XBAdvertViewDelegate> delegate; 
 
@property (nonatomic,strong) UIImage* adimage; 
 
@end

2.廣告的m文件
