我正在尝试使用CloudKit上传一些记录更改.我正在使用CKModifyRecordsOperation来批量上传设备上已更改的记录.记录都在自定义区域中
由于某种原因,操作不断回来,并告诉我“”保护数据不匹配“
这是代码：
- (void)updloadLocalChangesWithCompletionBlock:(void (^)(NSError *error))completionBlock
{
// Initialize the data
NSArray *localChanges = self.localChanges;
NSArray *localDeletions = self.localDeletions;
// Initialize the database and modify records operation
CKDatabase *database = [CKContainer defaultContainer].privateCloudDatabase;
CKModifyRecordsOperation *modifyRecordsOperation = [[CKModifyRecordsOperation alloc] initWithRecordsToSave:localChanges recordIDsToDelete:localDeletions];
modifyRecordsOperation.savePolicy = CKRecordSaveAllKeys;
NSLog(@"CLOUDKIT Changes Uploading: %d",localChanges.count);
// Add the completion block
modifyRecordsOperation.modifyRecordsCompletionBlock = ^(NSArray *savedRecords,NSArray *deletedRecordIDs,NSError *error) {
if (error) {
NSLog(@"[%@] Error pushing local data: %@",self.class,error);
}
[self.localChanges removeObjectsInArray:savedRecords];
[self.localDeletions removeObjectsInArray:deletedRecordIDs];
completionBlock(error);
};
// Start the operation
[database addOperation:modifyRecordsOperation];
}
这是它给我的错误：
[CloudKitSyncManager] Error Uploading Changes: <CKError 0x156654a0: "Partial Failure" (2/1011); "Failed to modify some records"; partial errors: { default-00001:(ZoneName:UserRecordID) = <CKError 0x1550b5a0: "Server Record Changed" (14/2037); "Error saving record <CKRecordID: 0x18080430; default-00001:(ZoneName:UserRecordID)> to server: Protection data didn't match"> }>
