如何在Swift应用内容中间插入AdMob自适应横幅广告？

你之前尝试直接拼接字符串和广告是行不通的——因为GADBannerView是UI组件，不是文本内容，没法和字符串直接相加。下面是两种可行的实现方案：

方案1：使用UITableView（适合长内容） #

把内容拆分成「文本块-广告-文本块」三个部分，用TableView的不同cell来承载：

步骤1：定义Cell类型 #

先创建两个自定义Cell：

// 显示文本的Cell
class TextContentCell: UITableViewCell {
    let contentLabel: UILabel = {
        let label = UILabel()
        label.numberOfLines = 0
        label.translatesAutoresizingMaskIntoConstraints = false
        return label
    }()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        contentView.addSubview(contentLabel)
        NSLayoutConstraint.activate([
            contentLabel.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 16),
            contentLabel.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16),
            contentLabel.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
            contentLabel.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -16)
        ])
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

// 显示广告的Cell
class AdBannerCell: UITableViewCell {
    var bannerView: GADBannerView!
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        setupBannerView()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    private func setupBannerView() {
        let adWidth = UIScreen.main.bounds.width - 32 // 左右留边
        let adSize = GADCurrentOrientationInlineAdaptiveBannerAdSizeWithWidth(adWidth)
        bannerView = GADBannerView(adSize: adSize)
        bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
        bannerView.rootViewController = self.window?.rootViewController
        bannerView.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(bannerView)
        
        NSLayoutConstraint.activate([
            bannerView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 16),
            bannerView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16),
            bannerView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
            bannerView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -16)
        ])
        
        // 加载广告
        bannerView.load(GADRequest())
    }
}

步骤2：分割内容并配置TableView #

在你的ViewController里：

class ContentViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    let tableView = UITableView()
    var firstHalfText = ""
    var secondHalfText = ""
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupTableView()
        splitContent()
    }
    
    private func splitContent() {
        let cont = "This is my content here" // 实际替换为WordPress接口返回的内容
        let words = cont.components(separatedBy: " ")
        guard !words.isEmpty else { return }
        let halfLength = words.count / 2
        firstHalfText = words[0..<halfLength].joined(separator: " ")
        secondHalfText = words[halfLength..<words.count].joined(separator: " ")
    }
    
    private func setupTableView() {
        tableView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(tableView)
        NSLayoutConstraint.activate([
            tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
            tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            tableView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor)
        ])
        
        tableView.register(TextContentCell.self, forCellReuseIdentifier: "TextCell")
        tableView.register(AdBannerCell.self, forCellReuseIdentifier: "AdCell")
        tableView.dataSource = self
        tableView.delegate = self
    }
    
    // MARK: - TableView DataSource
    func numberOfSections(in tableView: UITableView) -> Int {
        return 3 // 文本块1、广告、文本块2
    }
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        switch indexPath.section {
        case 0:
            let cell = tableView.dequeueReusableCell(withIdentifier: "TextCell", for: indexPath) as! TextContentCell
            cell.contentLabel.text = firstHalfText
            return cell
        case 1:
            let cell = tableView.dequeueReusableCell(withIdentifier: "AdCell", for: indexPath) as! AdBannerCell
            return cell
        case 2:
            let cell = tableView.dequeueReusableCell(withIdentifier: "TextCell", for: indexPath) as! TextContentCell
            cell.contentLabel.text = secondHalfText
            return cell
        default:
            return UITableViewCell()
        }
    }
}

方案2：使用UIStackView（适合短内容） #

如果内容不长，直接用StackView把文本标签和广告视图按顺序排列：

class ContentViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        setupContentAndAd()
    }
    
    private func setupContentAndAd() {
        // 1. 分割内容
        let cont = "This is my content here"
        let words = cont.components(separatedBy: " ")
        guard !words.isEmpty else { return }
        let halfLength = words.count / 2
        let firstHalf = words[0..<halfLength].joined(separator: " ")
        let secondHalf = words[halfLength..<words.count].joined(separator: " ")
        
        // 2. 创建文本标签
        let firstLabel = UILabel()
        firstLabel.text = firstHalf
        firstLabel.numberOfLines = 0
        
        let secondLabel = UILabel()
        secondLabel.text = secondHalf
        secondLabel.numberOfLines = 0
        
        // 3. 创建广告视图
        let adWidth = UIScreen.main.bounds.width - 32
        let adSize = GADCurrentOrientationInlineAdaptiveBannerAdSizeWithWidth(adWidth)
        let bannerView = GADBannerView(adSize: adSize)
        bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
        bannerView.rootViewController = self
        bannerView.load(GADRequest())
        
        // 4. 用StackView组合
        let stackView = UIStackView(arrangedSubviews: [firstLabel, bannerView, secondLabel])
        stackView.axis = .vertical
        stackView.spacing = 16
        stackView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(stackView)
        
        NSLayoutConstraint.activate([
            stackView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 16),
            stackView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 16),
            stackView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -16)
        ])
    }
}

注意事项 #

• 自适应横幅的宽度要根据实际布局设置（比如去掉左右内边距后的宽度），不要固定320，适配不同屏幕。
• 可以监听GADBannerViewDelegate的bannerViewDidReceiveAd(_:)和bannerView(_:didFailToReceiveAdWithError:)方法，处理广告加载成功/失败的布局调整。
• 测试时用AdMob提供的测试ID，上线前替换为正式ID。
