[英]saving fetched XMPPframeWork vCards into CoreData in Swift4
I was able to create and update a vCard using this code 我可以使用此代码创建和更新vCard
let xmppvCardStorage = XMPPvCardCoreDataStorage.sharedInstance()
let xmppvCardTempModule = XMPPvCardTempModule.init(vCardStorage:xmppvCardStorage!)
xmppvCardTempModule.activate(self.stream)
xmppvCardTempModule.addDelegate(self, delegateQueue: DispatchQueue.main)
let vCard = DDXMLElement(name: "vCard", xmlns: "vcard-temp")
let vCardTemp = XMPPvCardTemp.vCardTemp(from: vCard)
vCardTemp.nickname = "john"
vCardTemp.jid = XMPPJID(string: "john123@www.example.com")
Also I was able to fetch that vCard using the following code: 另外,我还可以使用以下代码来获取该vCard:
let xmppvCardStorage = XMPPvCardCoreDataStorage.sharedInstance()
let xmppvCardTempModule = XMPPvCardTempModule.init(vCardStorage: xmppvCardStorage!)
xmppvCardTempModule.activate(self.stream)
let jID = XMPPJID(string: "john@www.example.com")
xmppvCardTempModule.addDelegate(self,delegateQueue:DispatchQueue.main)
xmppvCardTempModule.fetchvCardTemp(for: jID!, ignoreStorage:false)
As you can see I am fetching the vCard from my server. 如您所见,我正在从服务器中获取vCard。 This is done by setting
ignoreStorage
to false
这是通过将
ignoreStorage
设置为false
来完成的
My question is does the XMPPFrameWork support a way to store the retrieved vCards in CoreData such that I don't have to retrieve it every time 我的问题是XMPPFrameWork是否支持一种将检索到的vCard存储在CoreData中的方法,这样我就不必每次都检索它
fetchvCardTemp
simply fetches the vCardTemp for the given JID if it is not in the storage.when you set ignoreStorage
to false you are saying that i don't want to use storage and i want to fetch it via the XMPPStream. fetchvCardTemp
简单地获取了vCardTemp对于给定的JID如果它不是在你设定的storage.when ignoreStorage
假你说的,我不希望使用存储,我想通过XMPPStream去取。 you should use just xmppvCardStorage and one of it's function called vCardTempForJID
and simply pass your favorite jID and it will return it to you 您应该只使用xmppvCardStorage及其功能之一,即
vCardTempForJID
然后简单地传递您喜欢的jID,它将其返回给您
