iOS 启动页广告详解

现在的项目中, 添加广告越来越普遍, 那么在启动页添加广告就是重中之重, 下面是我开发过程中的经验.

添加启动页广告的步骤

1.先创建一个UIViewController作为广告页.
2.请求广告.
3.显示广告.
4.缓存这次的广告信息.
5.下一次优先显示上次缓存的广告信息.

创建UIViewController

@interface UserBaseInfoVC : UIViewController

@end

• 在显示广告前, 应用启动页图片来代替广告, 这样就会给用户造成一个假象, 以为还在启动页.

#pragma mark - 启动页
- (void)setScreenForLauchScreen {
    
    self.LaunchImageView = [[UIImageView alloc] init];
    [self.view addSubview:self.LaunchImageView];
    
    if ([UIScreen mainScreen].bounds.size.height == 736) {
        self.LaunchImageView.image = [UIImage imageNamed:@"736"];
    }else if([UIScreen mainScreen].bounds.size.height == 667){
        self.LaunchImageView.image = [UIImage imageNamed:@"667"];
    }else if([UIScreen mainScreen].bounds.size.height == 568){
        self.LaunchImageView.image = [UIImage imageNamed:@"568"];
    }else if ([UIScreen mainScreen].bounds.size.height == 480){
        self.LaunchImageView.image = [UIImage imageNamed:@"480"];
    }else if ([UIScreen mainScreen].bounds.size.height == 812){
        self.LaunchImageView.image = [UIImage imageNamed:@"812"];
    }else if ([UIScreen mainScreen].bounds.size.height == 896){
        self.LaunchImageView.image = [UIImage imageNamed:@"896"];
    }
    
    [self.LaunchImageView mas_makeConstraints:^(MASConstraintMaker *make) {
        make.edges.equalTo(self.view);
    }];
}

• 请求广告

#pragma mark - 获取广告信息
- (void)getAdListData {
    [AdViewModel getAdDataSuccess:^(AdListModel * _Nonnull adList) {
        NSLog(@"获取广告信息 UserBaseInfoVC");
        if (adList) {
            //赋值
            [[SaveDataTools shareSaveDataTools] saveAdList:adList];
        }
    } fail:^(NSError * _Nonnull error) {
    }];
}

• 显示广告

 UIImageView *adImageView = [[UIImageView alloc] init];
    adImageView.userInteractionEnabled = YES;
        int arc4random = kArc4random([[SaveDataTools shareSaveDataTools] getAdList].tdList3.count);
        AdModel *adModel = [[SaveDataTools shareSaveDataTools] getAdList].tdList3[arc4random];
        __weak typeof(self) weakSelf = self;
        [self.view addSubview:adImageView];
        [adImageView mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.top.mas_equalTo(0);
            make.size.mas_equalTo(CGSizeMake(kScrentW, kScrentH - 60 - 30 - 30));
        }];
        //添加手势
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(clickAdImageViewTap)];
        [adImageView addGestureRecognizer:tap];
        
        //加载图片
        [adImageView sd_setImageWithURL:[NSURL URLWithString:adModel.image_url] placeholderImage:nil completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
            
            //隐藏启动页
            weakSelf.LaunchImageView.hidden = YES;
            
            //压缩图片
            image = [image scaleToWidth:kScrentW];
            if (image.size.height > (kScrentH - 120)) {
                adImageView.contentMode = UIViewContentModeCenter;
            }
            adImageView.image = image;
            
            //广告标记
            UIImageView *adtab = [[UIImageView alloc] init];
            adtab.image = [UIImage imageNamed:@"广告"];
            [weakSelf.view addSubview:adtab];
            [adtab mas_makeConstraints:^(MASConstraintMaker *make) {
                make.right.equalTo(adImageView);
                make.bottom.equalTo(adImageView);
            }];
            
            //底部
            UIImageView *bootomImageView = [[UIImageView alloc] init];
            bootomImageView.image = [UIImage imageNamed:@"启动页-icon"];
            [weakSelf.view addSubview:bootomImageView];
            [bootomImageView mas_makeConstraints:^(MASConstraintMaker *make) {
                make.centerX.equalTo(self.view);
                make.bottom.equalTo(self.view).offset(-30);
                make.size.mas_equalTo(CGSizeMake(173, 60));
            }];
            
            //赋值
            weakSelf.adModel = adModel;
        }];

• 缓存广告信息

#pragma mark - 获取广告信息
- (void)getAdListData {
    [AdViewModel getAdDataSuccess:^(AdListModel * _Nonnull adList) {
        NSLog(@"获取广告信息 UserBaseInfoVC");
        if (adList) {
            //赋值
            [[SaveDataTools shareSaveDataTools] saveAdList:adList];
        }
    } fail:^(NSError * _Nonnull error) {
    }];
}

• 到这基本上大功告成了.
