Swift learns the second practice--swift project time Movie

A previous OC Practice project was re-written with Swift, as the compatibility of the update to Swift for the Xcode version is also changing, and this version applies to xcode6.1.

This project uses Swift to encapsulate HTTP in the iOS official SDK, using Swift's method of loading the network images asynchronously. Practice the method of using Swift to operate the interface layout, jump interface and so on.

The following is the core code for the encapsulated download class:

Private var httpconnection:nsurlconnection?class zyhhttprequset: nsobject, Nsurlconnectiondatadelegate{    var requesturl:string?    var  downloaddata:nsmutabledata=nsmutabledata ()     var isDownloadSuccess:Bool?     var delegate:ZYHHttpRequestDelegate?    class func  Requestformurl (url:nsstring)->zyhhttprequset{        var  Oldrequest:zyhhttprequset?=zyhhttprequestmanager.sharedhttprequestmanager (). Requestforkey (URL)          if  (Oldrequest != nil) {             PRINTLN ("This task exists")              return oldRequest!        }         //New Download Task   &Nbsp;     var request:zyhhttprequset=zyhhttprequset ()          request.requestUrl=url         Request.startrequesturl (URL)          Zyhhttprequestmanager.sharedhttprequestmanager (). AddTask (Request, key: url)          return request    }         func stop () {        if httpconnection != nil  {            httpconnection?. Cancel ()             httpconnection = nil         }    }         //Start Download Request     private func startrequestURL (url:nsstring) {        if httpconnection != nil  {            httpconnection!. Cancel ()             httpConnection==nil         }        //Creating a Connection object          var request=nsurlrequest (Url: nsurl (string: url)!)         httpconnection=nsurlconnection (request: request,  Delegate: self)             }     //method     func connection in the rewrite protocol (connection: nsurlconnection,  Didreceiveresponse response: nsurlresponse)  {         downloaddata.length=0    }     func connection (Connection: nsurlconnection, didreceivedata data: nsdata )  {        downloaddata.appenddata (data)     }     func connectiondidfinishloading (connection: nsurlconnection)  {         isDownloadSuccess = true         delegate!. Zyhhttprequestsuccsee (self)          Zyhhttprequestmanager.sharedhttprequestmanager (). Removetaskfromurl (self.requesturl!)     }    func connection (connection: nsurlconnection,  Didfailwitherror error: nserror)  {        println ("Load failed ")         println (Error)          self.isdownloadsuccess=false   &nbSp;    zyhhttprequestmanager.sharedhttprequestmanager (). Removetaskfromurl (self.requestUrl!)     }                 }protocol zyhhttprequestdelegate{    func zyhhttprequestsuccsee ( Request:zyhhttprequset)}
