我以这种格式从API获取数据,但问题是我想从API获得所有问题和答案,但每当我尝试使用键值获取值时,它返回nil值并且应用程序崩溃
这是我从API获取数据的代码
Alamofire.request(url, method: .post, parameters: parameters,encoding: JSONEncoding.default, headers: header ).responseJSON {
response in
switch response.result {
case .success:
print(response)
if let result = response.result.value {
print(result)
let responseDict = result as! [String : Any]
print(responseDict)
let data = responseDict["Result"] as! [Any]
print(data)
}
break
case .failure(let error):
print(error)
}
}
你可以试试
if let res = responseDict["Result"] as? [[String:Any]] {
for item in res {
if let ques = item["Question"] as? String {
print(ques)
}
if let op = item["Options"] as? [[String:Any]] {
print(op)
}
}
}
