模棱两可地提及OCKCarePlanActivity成员的评估

Question

使用Xcode 9.4、Swift 3和CareKit框架1.2.1错误消息：

模棱两可地引用成员(withIdentifier:groupIdentifier:title:text:tintColor:resultResettable:schedule:userInfo:thresholds:optional:)‘的OCKCarePlanActivity评估

这是密码。

    let pulseActivity = OCKCarePlanActivity
            .assessment(withIdentifier: ActivityIdentifier.pulse.rawValue,
                        groupIdentifier: nil,
                        title: "Pulse",
                        text: "Do you have one?",
                        tintColor: UIColor.darkGreen(),
                        resultResettable: true,
                        schedule: CarePlanData.dailyScheduleRepeating(occurencesPerDay: 1),
                        userInfo: ["ORKTask": AssessmentTaskFactory.makePulseAssessmentTask()]
)

更新的CareKit框架添加了可选参数。

let pulseActivity = OCKCarePlanActivity
        .assessment(withIdentifier: ActivityIdentifier.pulse.rawValue,
                    groupIdentifier: nil,
                    title: "Pulse",
                    text: "Do you have one?",
                    tintColor: UIColor.darkGreen(),
                    resultResettable: true,
                    schedule: CarePlanData.dailyScheduleRepeating(occurencesPerDay: 1),
                    userInfo: ["ORKTask": AssessmentTaskFactory.makePulseAssessmentTask()],
                    optional: true) //--> NEW

这一变化纠正了我的错误。希望它能帮助别人。
