我试图让设备运动(俯仰,滚动,偏航),但是我的函数handleDeviceMotionUpdate没有启动(我在
iphone 5s上尝试它),这里是代码：
import UIKit
import CoreMotion
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
var motionManager = CMMotionManager()
motionManager.startDeviceMotionUpdates()
motionManager.deviceMotionUpdateInterval = 0.1
motionManager.startDeviceMotionUpdatesToQueue(
NSOperationQueue.currentQueue()!,withHandler: {
(deviceMotion,error) -> Void in
if(error == nil) {
self.DeviceMotionUpdate(deviceMotion!)
} else {
print("error")
}
})
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func DeviceMotionUpdate(deviceMotion:CMDeviceMotion) {
print("function launched")
var attitude = deviceMotion.attitude
var roll = (attitude.roll)
var pitch = (attitude.pitch)
var yaw = (attitude.yaw)
print("Roll: \(roll),Pitch: \(pitch),Yaw: (yaw)")
}
}
我没有在startDeviceMotionUpdatesToQueue中得到错误.我在motionManager.deviceMotionActive和motionManager.deviceMotionAvailable上都是如此
