ios - 关于 :Please add -ObjC to 'Other Linker Flags' in your project settings 的 card-io 异常

Question

我没有使用 CocoaPods 将 Core-io 添加到我的项目中
然后我遵循了正确的步骤:

1. 下载最新版本:card.io-iOS-SDK-5.2.2
2. 将 CardIO 目录添加到我的项目
3. 在 PROJECTS 部分，将 -lc++ 添加到 Other Linker Flags
4. 仅将这些框架添加到我的项目中:(Accelerate、AVFoundation、AudioToolbox、CoreMedia、MobileCoreServices)
5. 确认这两个build设置都已启用:(启用模块(C 和 Objective-C)、自动链接框架)

这是我的简单代码:

//用户确认扫描信息
func userDidProvideCreditCardInfo(cardInfo: CardIOCreditCardInfo!, inPaymentViewController paymentViewController: CardIOPaymentViewController!) {
    if let card = cardInfo {
        labelResult.text = "卡号:\(card.cardNumber)\n过期年月:\(card.expiryYear)年\(card.expiryMonth)月\nCVV:\(card.cvv)"
    }
    paymentViewController.dismissViewControllerAnimated(true, completion: nil)
}

开始扫描:

//begin scan
@IBAction func startScan(sender: UIButton) {
    let cardVC = CardIOPaymentViewController(paymentDelegate: self)
    cardVC.modalPresentationStyle = .FormSheet
    presentViewController(cardVC, animated: true, completion: nil)
}

以下是异常:

我尝试将 -ObjC 添加到 Other Linker Flags，但构建失败。

Answer 1

我将 -l"CardIO"添加到其他链接器标志，它对我有用
