我正在尝试用Swift解析我的api响应。
但是,我有以下错误
线程8:信号sigabret
我的json模态类是
struct storyDataClass : Codable {
var storyDictionary : storyDictionary?
}
struct storyDictionary: Codable {
var nameString : String?
var lineString : String?
var image : String?
}
而API调用是
dataViewModelClass.getData(completionHandler: {data, error -> Void in
if (data != nil) {
print(data?.count)
if let retriveData = data {
for (index,value) in retriveData.enumerated() {
print(index)
// print(value)
var dataJson = storyDataClass.init(storyDictionary: value as! storyDictionary)
print(dataJson.storyDictionary?.lineString)
}
}
} else {
print("api.getData failed")
print(error as! NSError)
}
})
在响应中,value在Story key下有多个字典。
{
"name" = "name";
line = "some name";
"image" = "https://";
}
{
"name" = "name";
line = "some name";
"image" = "https://";
}
以及API回调方法
class DataViewViewModel {
typealias DataCompletion = (String) -> Void
func getData(completionHandler: ((Array<Any>?, Error?) -> Void)!) -> Void {
let url = URL(string: mainDataURL)
URLSession.shared.dataTask(with:url!) { (data, response, error) in
if error != nil {
print(error?.localizedDescription ?? "Error")
return completionHandler(nil, error)
} else {
do {
let parsedData = try JSONSerialization.jsonObject(with: data!) as! [String:Any]
let itemsArray = parsedData["items"] as! Array<Any>
print(itemsArray)
return completionHandler(itemsArray, nil)
} catch let error as NSError {
print(error)
}
}
}.resume()
}
}
有什么建议吗?
