我正在使用带有CKFetchRecordsChangeToken的CKFetchRecordChangesOperation来获取更改,它告诉我“AppDefaultZone不支持同步语义”。
以下是有问题的代码:
- (void)downloadServerChangesWithCompletionBlock:(void (^)(NSError *error))completionBlock
{
// Prepare to fetch remote changes
CKDatabase *database = [CKContainer defaultContainer].privateCloudDatabase;
CKRecordZoneID *zoneID = [[CKRecordZoneID alloc] initWithZoneName:CKRecordZoneDefaultName ownerName:CKOwnerDefaultName];
// Initialize fetch record changes operation
CKFetchRecordChangesOperation *fetchRecordChangesOperation = [[CKFetchRecordChangesOperation alloc] initWithRecordZoneID:zoneID previousServerChangeToken:[self changeToken]];
fetchRecordChangesOperation.recordChangedBlock = ^(CKRecord *record) {
[self performRecordChange:record];
};
fetchRecordChangesOperation.recordWithIDWasDeletedBlock = ^(CKRecordID *recordID){
[self performRecordDeletion:recordID];
};
fetchRecordChangesOperation.fetchRecordChangesCompletionBlock = ^(CKServerChangeToken *serverChangeToken, NSData *clientChangeTokenData, NSError *error) {
if (error) {
completionBlock(error);
} else {
[self setChangeToken:serverChangeToken];
completionBlock(nil);
}
};
// Perform the operation
[database addOperation:fetchRecordChangesOperation];
}
这是打印出来的错误
[PBCloudKitSyncManager] Error Downloading Data:
<CKError 0x157a2500: "Server Rejected Request" (15/2027);
server message = "AppDefaultZone does not support sync semantics";
uuid = [redacted];
container ID = "[redacted]">
答案 0 :(得分:2)
我通过切换到自定义区域来解决问题。我在初始化CloudKit时创建了区域,当我初始化zoneID时,我使用它:
CKRecordZoneID *zoneID = [[CKRecordZoneID alloc] initWithZoneName:@"Custom Zone Name" ownerName:userRecordName];
其中userRecordName是我在Cloudkit初始化中调用此方法时为用户获取的CKRecord的记录名称:
[CKContainer defaultContainer] fetchUserRecordIDWithCompletionHandler:^(CKRecordID *recordID, NSError *error) {
if (recordID) {
// Save the user record id
[self saveUserRecordName:recordID.recordName];
/...
}
}];
