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。

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

objectivec 复制代码

#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

objectivec 复制代码

#import "SDFullScreenADView.h"

#define kMainScreenWidth [UIScreen mainScreen].bounds.size.width

@interface SDFullScreenADView ()

@property (nonatomic, strong) UIImageView *adImageView;   //广告界面
@property (nonatomic, strong) UIButton *skipButton;       //跳过按钮
@property (nonatomic, strong) UILabel *timeLabel;         //倒计时控件

@property (nonatomic, strong) NSTimer *displayTimer;         //剩余时间倒计时

@end

@implementation SDFullScreenADView
