当我点击“同意”按钮时,它应该转到consentCompletionStep但它会同意不同意步骤。任何人都可以指出问题是什么吗?

问题是传递给+predicateForConsentWithResultSelector:didConsent:
的resultSelector必须提供所需的步骤标识符(stepIdentifier参数)和所需的签名标识符(resultIdentifier参数)。
而不是:
let resultSelector = ORKResultSelector(resultIdentifier:String(describing: Identifier.consentReviewStep))
let predicateAgree = ORKResultPredicate.predicateForConsent(with: resultSelector, didConsent: true)
应该是:
let resultSelector = ORKResultSelector(stepIdentifier: String(describing: Identifier.consentReviewStep), resultIdentifier: signature.identifier)
let predicateAgree = ORKResultPredicate.predicateForConsent(with: resultSelector, didConsent: true)
