请告诉我，由于可选的json，我无法解析此josn响应，我无法在标签中进行解析
我已经尽力了，但是我是新手，所以我无法解开可选的json 响应：：

因为这个原因，我在所有类似名称文本的推文中都获得了零价值，请告诉我如何解决这个问题
var timeline = (FHSTwitterEngine.shared().getTimelineForUser(FHSTwitterEngine.shared().authenticatedUsername, isID: true, count: 10), terminator: "")
从这一行中我得到了完整的答复
然后我在数组上创建并存储到下面的数组中
var serviceData = [AnyObject]()
let timelinedata = [timeline] as [AnyObject]
serviceData = (timelinedata)
print(serviceData)
答案 0 :(得分：0)
通常，任何可选内容都可以像这样展开：
let optionalValue: String? = "Hello, this is optional!"
if let noLongerOptional = optionalValue {
print("\(noLongerOptional) no its not! ahah")
}
编辑：更具体的示例...
假设您有一个变量“ myJson”，其中包含您的可选值...并且您做到了：
print("\(myJson)")
您可以通过以下方法解决此问题：
if let validJson = myJson {
print("\(validJson)")
}
编辑2：... FHSTwitter ...（已更新。...时间越来越长）
let twitterEngine = FHSTwitterEngine.sharedEngine()
let twitterUser = twitterEngine.authenticatedID
let timeline = twitterEngine.getTimelineForUser(twitterUser, isID: true, count: 10)
根据FHSTwitterEngine文档... getTimelineForUser（）将返回NSError或Tweets数组。
所以...
if let error = timeline as? Error {
print("Oops, looks like something went wrong: \(error)")
} else {
if let tweets = timeline as? [Any] {
for tweet in tweets {
print("This is a tweet: \(tweet)")
}
}
}
