迅速，传球类数据的viewController

Question

我从插座

数据获取和存储我它的对象 我用NSNotificationCenter。有没有另一种方式将这些数据从套接字类直接传递给Controller？

Answer 1

创建ResponseDelegate协议

protocol ResponseDelegate { 
    func didReceiveResponse(data:AnyObject?) 
} 

在插座类

class SocketClass { 
    var responseDelegate:ResponseDelegate //This should be implemented and referred to your ViewController 

    func getCurrentAmount() { 
     [socket on:@"currentAmount" callback:^(NSArray* data, SocketAckEmitter* ack) { 
      responseDelegate.didReceiveResponse(data) 
     } 
    } 
} 

对您的委托引用在你ViewController

//Set your delegate here 
socketClassObject.responseDelegate = self 

func didReceiveResponse(data:AnyObject) { 
     println("Recieved data:\(data)") 
} 

使用NSNotificationsCentre

在你的ViewController

//Subscribe/Listen for the events 
NSNotificationCenter.defaultCenter().addObserver(self, selector: "didReceiveResponse:", name:"CurrentAmountNotification", object: nil) 

func didReceiveResponse(notification: NSNotification) { 
     println("Recieved data:\(notification.userInfo)") 
} 

在你SocketClass

class SocketClass { 

    func getCurrentAmount() { 
     [socket on:@"currentAmount" callback:^(NSArray* data, SocketAckEmitter* ack) { 
      NSNotificationCenter.defaultCenter().postNotificationName("CurrentAmountNotification", object: nil, userInfo:data) 
     } 
    } 
} 

Answer 2

你得给SEGUE在故事板的标识符。（说vs_segue）

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?){....} 

是要求所有塞格斯被称为表格当前的UIViewController。因此，标识是区分不同塞格斯

然后使用此代码：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "vs_segue" { 
    var nextScene = segue.destinationViewController as! VehicleDetailsTableViewController 

    // Pass the selected object to the new view controller. 
     nextScene.currentObjectInNextScreen = selectedObjectWhichYouHave 
    } 
} 

广场VAR nextScene后一个破发点，看看它是否正在对点击/更改视图控制器触发。如果不是，那么故事板中提供的标识符名称必须与此处给出的名称不同。

谢谢

快乐编码。
