在swift 1.2中解决JSON问题
我遇到了JSON解析的问题，我的参数没有得到正确的数据响应。我已经坚持这个问题很长一段时间了。我不知道如何解决它。我是iOS开发的新手。我也没有使用任何第三方库。[不知道如何使用它们]
我在第一次迭代时获得了正确的响应，但是对于下一次迭代，上一次迭代的结果与新结果一起被添加。就像每个循环结果以上一次迭代的结果结束
我的JSON SAMPLE。 [可提供链接，请告知我们]
struct AssetItems {
var Name:String
var Desc:String
var Image:String
var entityId:String
var aFileType:String
var aFileSize:String
var aFileCreatedDate:String
var aFileRevisionDate:String
var aFileModifiedDate:String
var aProductName:String
var aVersion:String
var aAssetType:String
var aIsFolder:String
init(assetName:String,assetDescription:String,assetImage:String,entityId:String,FileType:String,FileSize:String,FileCretedDate:String,FileReveisionDate:String,FileModifiedDate:String,ProductName:String,Version:String,AssetType:String,IsFolder:String) {
self.Name = assetName
self.Desc = assetDescription
self.Image = assetImage
self.entityId = entityId
self.aFileType = FileType
self.aFileSize = FileSize
self.aFileCreatedDate = FileCretedDate
self.aFileRevisionDate = FileReveisionDate
self.aFileModifiedDate = FileModifiedDate
self.aProductName = ProductName
self.aVersion = Version
self.aAssetType = AssetType
self.aIsFolder = IsFolder
}
}
struct AssetModel {
var aName:String
var aDesc:String
var aCount:String
var aEntityId:String
var items:[AssetItems]
init(rackName:String,rackDescription:String,totalNoAssets:String,EntityId:String,rackItems:[AssetItems]) {
self.aName = rackName
self.aDesc = rackDescription
self.aCount = totalNoAssets
self.aEntityId = EntityId
self.items = rackItems
}
}
var assetData:Array<AssetModel> = Array<AssetModel>()
var assetContents:Array<AssetItems> = Array<AssetItems>()
这就是我如何参与JSON
func get_data_from_Url(url:String) {
let url = NSURL(string: url)
var request:NSMutableURLRequest = NSMutableURLRequest(URL: url!)
request.HTTPMethod = "GET"
request.addValue("application/json", forHTTPHeaderField: "Content_Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
var responseError : NSError?
var response : NSURLResponse?
var urlData: NSData? = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &responseError)
if(urlData != nil) {
var responseData:NSString = NSString(data: urlData!, encoding: NSUTF8StringEncoding)!
let res = response as! NSHTTPURLResponse
var err:NSError?
if (res.statusCode == 200)
{
var parseError: NSError?
let json:AnyObject = NSJSONSerialization.JSONObjectWithData(urlData!, options:NSJSONReadingOptions.MutableContainers , error: &err) as AnyObject!
if (parseError == nil) // no error while parsing
{
if let Asset_list = json as? NSArray
{
for (var i = 0; i < Asset_list.count ; i++ )
{
if let Asset_obj = Asset_list[i] as? NSDictionary
{
if let AssetGroupName = Asset_obj["Name"] as? String
{
if let AssetGroupDescription = Asset_obj["Description"] as? String
{
if let entityId = Asset_obj["EntityId"] as? String
{
if let totalAssets = Asset_obj["_NoOfAssets"] as? String
{
if let items = Asset_obj["Items"] as? NSArray
{
for (var j=0 ; j < items.count; j++)
{
if let asset_items = items[j] as? NSDictionary
{
if let AbsolutePath = asset_items["AbsolutePath"] as? String
{
if let Description = asset_items["_Description"] as? String
{
if let Name = asset_items["_Name"] as? String {
if let entityId = asset_items["EntityId"] as? String
{
if let FileType = asset_items["_FileType"] as? String
{
if let FileSize = asset_items["_FileSize"] as? String
{
if let FileCreatedDate = asset_items["CreatedDate"] as? String
{
if let FileModifiedDate = asset_items["ModifiedDate"] as? String
{
if let RevisionDate = asset_items["RevisionDate"] as? String
{
if let productName = asset_items["ProductName"] as? String
{
if let version = asset_items["Version"] as? String
{
if let AssetType = asset_items["_AssetType"] as? String
{
if let isFolder = asset_items["IsFolder"] as? String
{
var add = AssetItems(assetName: Name, assetDescription: Description, assetImage: AbsolutePath, entityId: entityId, FileType: FileType, FileSize: FileSize, FileCretedDate: FileCreatedDate, FileReveisionDate: RevisionDate, FileModifiedDate: FileModifiedDate, ProductName: productName, Version: version, AssetType: AssetType, IsFolder: isFolder)
assetContents.append(add)
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
var add_it = AssetModel(rackName: AssetGroupName, rackDescription: AssetGroupDescription, totalNoAssets: totalAssets, EntityId: entityId, rackItems: assetContents)
assetData.append(add_it)
}
}
}
}
}
}
}
}
}
}
}
do_table_refresh()
}
func do_table_refresh()
{
dispatch_async(dispatch_get_main_queue(),
{
self.tableView.reloadData()
})
return
}
我的输出
请有人帮我解决这个问题，任何建议都可以。
感谢
答案 0 :(得分：1)
特别感谢@SMi，凭借他的GuidLines，我能够解决我的问题。 我知道我必须在循环结束时清除内部数组[但是，我不知道如何清除它。]
var add_it = AssetModel(rackName: AssetGroupName, rackDescription: AssetGroupDescription, totalNoAssets: totalAssets, EntityId: entityId, rackItems: assetContents)
assetData.append(add_it)
assetContents.removeAll()
我所要做的就是使用 .removeAll（）方法清除 assetContents 数组。
