iOS 和 NativeScript 的最佳实践

委托、委托、委托！

始终保留您在自定义 iOS 类中使用的自定义委托实现。如果不这样做，可能会导致您的委托过早被垃圾回收，并且功能无法按预期工作。

例如

错误

let applePayController: PKPaymentAuthorizationViewController

applePayController =
  PKPaymentAuthorizationViewController.alloc().initWithPaymentRequest(
    paymentRequest
  )
applePayController.delegate =
  PKPaymentAuthorizationViewControllerDelegateImpl.initWithOwner(this)

正确

let applePayController: PKPaymentAuthorizationViewController
let applePayControllerDelegate: PKPaymentAuthorizationViewControllerDelegateImpl

applePayController =
  PKPaymentAuthorizationViewController.alloc().initWithPaymentRequest(
    paymentRequest
  )
applePayControllerDelegate =
  PKPaymentAuthorizationViewControllerDelegateImpl.initWithOwner(this)
applePayController.delegate = applePayControllerDelegate

委托、委托、委托！ ​
