swift - 如何使用 slider 设置 WKInterfaceTimer 的时间值

Question

我正在创建一个测试应用程序来习惯 WatchKit，并且想知道是否可以使用 slider 来设置倒计时时间。到目前为止我有这个:

import WatchKit
import Foundation

class InterfaceController: WKInterfaceController {

@IBOutlet weak var footText: WKInterfaceLabel!
@IBOutlet weak var timerOutput: WKInterfaceTimer!

@IBAction func button() {
}
@IBAction func timeSlider(value: Float) {
var myValue = String(format: "Value is %f", value)
    func setAttributedText(attributedText: NSAttributedString?) {}

}
var testtest = "This is a test"

override func awakeWithContext(context: AnyObject?) {
    super.awakeWithContext(context)

    // Configure interface objects here.
}

override func willActivate() {
    // This method is called when watch view controller is about to be visible to user
    super.willActivate()
}

override func didDeactivate() {
    // This method is called when watch view controller is no longer visible
    super.didDeactivate()
}

}

是否可以更改计时器的值？

Answer 1

如果你想改变定时器的值，你可以这样设置:

• 首先，使用 slider 更改 countTime 的值

• 之后，您可以根据您的计数时间设置计时器:

  timer.setDate(NSDate(timeIntervalSinceNow: countTime)) 定时器.start()

希望这有帮助!
