I am programming an iOS app using swift where i have 3 UILabels which will show data different sensors data into the same corresponding labels.
These are 3 labels which i am using.
@IBOutlet weak var xAccel: UILabel!
@IBOutlet weak var yAccel: UILabel!
@IBOutlet weak var zAccel: UILabel!
I am using UIsegmentedControl to change the display of data which is as follows.
@IBAction func AccelDidChange(_ sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0:
myAccelerometer()
break
case 1:
myGyroscope()
break
default:
myAccelerometer()
}
Above used 2 functions are as follows
func myAccelerometer() {
// sets the time of each update
motion.accelerometerUpdateInterval = 0.1
//accessing the data from the accelerometer
motion.startAccelerometerUpdates(to: OperationQueue.current!) { (data, error) in
// can print the data on the console for testing purpose
//print(data as Any)
if let trueData = data {
self.view.reloadInputViews()
//setting different coordiantes to respective variables
let x = trueData.acceleration.x
let y = trueData.acceleration.y
let z = trueData.acceleration.z
//setting the variable values to label on UI
self.SensorName.text = "Accelerometer Data"
self.xAccel.text = "x : \(x)"
self.yAccel.text = "y : \(y)"
self.zAccel.text = "z : \(z)"
}
}
}
func myGyroscope() {
motion.gyroUpdateInterval = 0.1
motion.startGyroUpdates(to: OperationQueue.current!) { (data, error) in
if let trueData = data {
self.view.reloadInputViews()
//setting different coordiantes to respective variables
let x = trueData.rotationRate.x
let y = trueData.rotationRate.y
let z = trueData.rotationRate.z
//setting the variable values to label on UI
self.SensorName.text = "Gyroscope Data"
self.xAccel.text = "x: \(x)"
self.yAccel.text = "y: \(y)"
self.zAccel.text = "z: \(z)"
}
}
}
** Problem is it keeps on displaying both the Accelerometer and Gyroscope data on UILabels at the same time instead of only showing the data of a particular sensor when tapped. I have tried to use the break option but still not working. If any one could point out the possible solution, that would be great. Thanks **
EIDT - Here is the output on screen where you can see the values fluctuates between different sensors. I only want readings from 1 sensor at a time. https://imgur.com/a/21xW4au
@IBAction func AccelDidChange(_ sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0:
motion.stopGyroUpdates()
myAccelerometer()
break
case 1:
motion.stopDeviceMotionUpdates()
myGyroscope()
break
default:
myAccelerometer()
}
}
You need to stop unneeded resource before the switch. Try this please
