到目前为止一切顺利。

推荐答案

样本中由用户手动输入的HealthKit将具有 HKMetadataKeyWasUserEntered 元数据键的YES值。要创建仅匹配非用户输入的样本的谓词，您可以使用以下内容：

Samples in HealthKit that were manually entered by the user will have have a YES value for the HKMetadataKeyWasUserEntered metadata key. To create a predicate that matches only samples that were not user-entered, you could do use the following:

[NSPredicate predicateWithFormat:@"metadata.%K != YES", HKMetadataKeyWasUserEntered];

请注意，这必须表示为 value！= YES 因为键的值可以是YES，NO或nil，nil表示NO。

Note that this must be formulated as value != YES because the value for the key could be YES, NO, or nil and nil implies NO.
