CKModifyRecordsOperation对象的recordsToSave属性能否在其modifyRecord CompletionBlock中安全使用

假设我使用CKModifyRecordsOperation对象启动saveOperation。当我在操作完成后执行的modifyRecordsCompletionBlock中访问该对象时,我可以安全地假设该对象的recordsToSave将存储开始时给定的记录列表吗。

我想是这样,但后来我在Apple文档中看到了这一行(基本上不确定“initial”是什么意思:数组的初始内容被设置为您在initWithRecordsToSave:recordIDsToDelete:方法中指定的记录。您可以在执行操作之前根据需要修改此数组。

如果在极少数情况下它可以改变,那么我想在我的重试逻辑中走另一条路。

EDIT添加代码

   CKModifyRecordsOperation *saveOperation = [[CKModifyRecordsOperation alloc] initWithRecordsToSave:recordsToSave recordIDsToDelete:nil] ;
saveOperation.modifyRecordsCompletionBlock = completionBlock ; //see completion block definition below
[self.publicDatabase addOperation:saveOperation] ; 

[self.OperationQ addObject: saveOperation] ; //Saved in Q for later retrieval 

completionBlock定义为

  ^(NSArray *savedRecords, NSArray *deletedRecordIDs, NSError * operationError){
 if(operationError)
 {
    DDLogError(@"Save of Touch event records failed with error %@",operationError) ;
    //Retry, can I do this and safely assume first record retrieved here is the first record I inserted into original recordsToSave array

    CKRecord *cardinalRecord = self.OperationQ[0].recordsToSave[0] ;

     //Read a field from it to decide how to handle retry (e.g: retry after delay if important set of records, don't retry if not etc)..
 }
 else
 {
   //Handle success case
 }
}
