iOS开发-启动页广告实现

启动页广告实现是一个非常常见的广告展示模式。就是在启动时候显示广告，之后点击跳转到广告页面或者其他APP。

在这里插入图片描述

一、实现启动页广告

启动页广告控件实现，将View放置在keyWindow上，显示广告图片，点击广告图片进行跳转。
如果没有操作，倒计时5s后进行App

具体代码如下

SDFullScreenADView.h

#import <UIKit/UIKit.h>#define kFullScreenAdTag  9012//跳转按钮样式
typedef NS_ENUM(NSUInteger, SDSkipButtonType) {SDSkipButtonTypeText = 0,
};typedef void(^SDFullScreenADBlock)();@interface SDFullScreenADView : UIView/**广告图的显示时间（默认5秒）*/
@property (nonatomic, assign) NSUInteger duration;/**右上角按钮的样式（默认倒计时+跳过）*/
@property (nonatomic, assign) SDSkipButtonType skipType;/**广告图*/
@property (nonatomic, strong) UIImage *adImage;/**广告数据，跳转数据*/
@property (nonatomic, strong) id data;@property (nonatomic, copy) SDFullScreenADBlock block;/**显示广告*/
- (void)show;/**默认广告@return id*/
+ (SDFullScreenADView *)defaultFullScreenADView;@end

SDFullScreenADView.m

#import "SDFullScreenADView.h"#define kMainScreenWidth [UIScreen mainScreen].bounds.size.width@interface SDFullScreenADView ()@property (nonatomic, strong) UIImageView *adImageView;   //广告界面
