控制台或设备上的崩溃日志中是否有任何消息？当您收到“操作无法完成”时Cocoa API中的错误，它通常表示与负责执行操作的系统守护进程通信时发生某种故障。例如，在这种情况下，healthd可能已崩溃。我收到的唯一控制台消息是：“***向训练添加样本时出错：操作无法完成。（Cocoa错误4097。）***"这很可能意味着healthd在响应您的请求时崩溃。您应该找到healthd崩溃日志，然后向Apple提交一个错误：。@tshortli，详细检查我的回答，确认崩溃是由于samples可变数组造成的。该数组包含一组HKQuantityType对象，但它应该是HKQuantitySample或HKCategorySample.T谢谢，我确实从一个样本中看到HealthKit中的“334”kcal，这正是我所需要的。一个问题，当使用workoutWithActivityType创建HKWorkout对象时，变量“energyBurned”是作为一个参数包含的，似乎没有使用。由于HKSample实际提供kcal，我可以将nil传递给此参数吗？如果不是，我如何处理此无关代码？@MattMiller，根据苹果的HealthKit设计理念，HKSample是HKQuantitySample和HKCategorySample类的基类。HKSample的目的是在我们的案例中，要存储样本的类型，它是“HKQuantityTypeIdentifierActivityBurned”。但是，HKSample不能存储数据的度量值（数量/类别）。存储此类数据是HKSample的子类的责任。即使无法通过“init”方法实例化HKSample。
