我需要让iPhone振动,但我不知道如何在Swift中做到这一点.我知道在Objective-C中,你只需写:

import AudioToolbox
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);

但那不适合我.

我正在Swift中编写一个iOS游戏,我想在最后添加一个高分标签.我认为保存功能是正确的,但负载一是给我带来问题的.我已经创建了一个实体("BestScores")和属性("classicBestScoreTF"):

要保存高分:

var bestscore25 = 1000
var score: int

func savescore() {    
    var appDel: AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
    var context:NSManagedObjectContext = appDel.managedObjectContext!
    var score25: AnyObject! = NSEntityDescription.insertNewObjectForEntityForName("BestScores", inManagedObjectContext: context) as NSManagedObject
    score25.setValue(score, forKey: "classicBestScoreTF")
    context.save(nil)
}

func loadscore() {
    var appDel: AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
    var context:NSManagedObjectContext = appDel.managedObjectContext!
    bestScore25 = valueForKey("classicBestScoreTF") as Int
}

func endgame() {

    if score > bestScore25 {
        savescore()
        loadscore()
        bestScoreLabel.text = "Best Score: \(bestScore25)"
    }

    if score < bestscore {            
        loadscore()
        bestScoreLabel.text …
