When closing lines of a polygon that after the third point in the map marking calculates an area between the points, it presented an error after the iOS 15.0 update. Some tests they work but most tests performed the polygon does not close visually and does not show the calculation. Even previous versions did not have this error.

i have 3 annotation and i draw polyline between first and second annotation but i need the therd one move over that polyline but it's always move in street polyline to the destnation
-my code
func moveDelivery(_ destinationCoordinate : CLLocationCoordinate2D{
self.deliveryAnnotation.coordinate = CLLocationCoordinate2DMake(29.959640, 31.270421)
let sourcePlaceMark = MKPlacemark(coordinate: self.userAnnotation.coordinate)
//sourcePlaceMark.title
let destPlaceMkark = MKPlacemark(coordinate: self.deliveryAnnotation.coordinate)
let sourceItem = MKMapItem(placemark: sourcePlaceMark)
let destItem = MKMapItem(placemark: destPlaceMkark)
let directionRequest = MKDirections.Request()
directionRequest.source = sourceItem
directionRequest.destination = destItem
directionRequest.transportType = .any
let direction = MKDirections(request: directionRequest)
direction.calculate(completionHandler: {
response, error in
guard let response = response else {
if let error = error {
print(error.localizedDescription)
} else {
self.deliveryAnnotation.courseDegrees = self.getHeadingForDirectionFromCoordinate(self.kitchenAnnotation.coordinate, toLoc: self.userAnnotation.coordinate)
self.view.transform = CGAffineTransform(rotationAngle:CGFloat(self.deliveryAnnotation.courseDegrees))
}
return
}
guard let primaryRoute = response.routes.first else { return }
let route = response.routes[0]
self.mapView.addOverlay(route.polyline, level: .aboveRoads)
let rekt = route.polyline.boundingMapRect
self.mapView.setRegion(MKCoordinateRegion(rekt), animated: true)
})
//
UIView.animate(withDuration: Double(60), animations: {
self.deliveryAnnotation.coordinate = destinationCoordinate
}, completion: { success in
if success {
}
})
}
Your third annotation isn't following the route because you're animating it moving in a straight line between the first and second line. Try getting the coordinates from the MKRoute's polyline and animate between each one (According to apple's docs MKRoutes are made up of coordinates, but you might be able to use points as well)
If you'd like it to animate over the span of 60 seconds:
func moveDelivery(_ destinationCoordinate: CLLocationCoordinate2D) {
// I don't know why you have the delivery annotation start here, is this for testing?
deliveryAnnotation.coordinate = CLLocationCoordinate2DMake(29.959640, 31.270421)
let sourcePlaceMark = MKPlacemark(coordinate: destinationCoordinate)
let destPlaceMkark = MKPlacemark(coordinate: userAnnotation.coordinate)
let directionRequest = MKDirections.Request()
directionRequest.source = MKMapItem(placemark: sourcePlaceMark)
directionRequest.destination = MKMapItem(placemark: destPlaceMkark)
directionRequest.transportType = .any
let direction = MKDirections(request: directionRequest)
direction.calculate(completionHandler: {
response, error in
guard let response = response else {
print("MKRequest gave no response")
if let error = error {
print(error.localizedDescription)
} else {
self.deliveryAnnotation.courseDegrees = self.getHeadingForDirectionFromCoordinate(self.kitchenAnnotation.coordinate, toLoc: self.userAnnotation.coordinate)
self.view.transform = CGAffineTransform(rotationAngle:CGFloat(self.deliveryAnnotation.courseDegrees))
}
return
}
guard let primaryRoute = response.routes.first else {
print("response has no routes")
return
}
self.mapView.addOverlay(primaryRoute.polyline, level: .aboveRoads)
let rekt = primaryRoute.polyline.boundingMapRect
self.mapView.setRegion(MKCoordinateRegion(rekt), animated: true)
let coordinateArray = primaryRoute.polyline.coordinates
assert(coordinateArray.count > 0, "coordinate array is empty")
self.routeCoordinates = coordinateArray
// initiate recursive animations
self.coordinateIndex = 0
})
}
var routeCoordinates = [CLLocationCoordinate2D]()
var avgAnimationTime: Double {
return 60 / Double(routeCoordinates.count)
}
var coordinateIndex: Int! {
didSet {
guard coordinateIndex != routeCoordinates.count else {
print("animated through all coordinates, stopping function")
return
}
animateToNextCoordinate()
}
}
func animateToNextCoordinate() {
let coordinate = routeCoordinates[coordinateIndex]
UIView.animate(withDuration: avgAnimationTime, animations: {
self.deliveryAnnotation.coordinate = coordinate
}, completion: { _ in
self.coordinateIndex += 1
print("moved between coordinates")
})
}
EDIT
make sure to include this extension, otherwise you won't be able to get the coordinates of the MKRoute (source: https://gist.github.com/freak4pc/98c813d8adb8feb8aee3a11d2da1373f)
public extension MKMultiPoint {
var coordinates: [CLLocationCoordinate2D] {
var coords = [CLLocationCoordinate2D](repeating: kCLLocationCoordinate2DInvalid,
count: pointCount)
getCoordinates(&coords, range: NSRange(location: 0, length: pointCount))
return coords
}
}
EDIT #2
See above, edited original answer to animate through each coordinate after the previous finishes animating. Really rough but it should work.
EDIT #3
Added your code to get the destination variable as well as some assert and debug printing calls. If things aren't working this time, please tell me which debug messages you get.
EDIT #4

Below I have a list of cities and I compare a user's current location to the cities and use the (min) function
let closestCity = min(theDistanceInMetersFromBusselton,theDistanceInMetersFromBunbury,theDistanceInMetersFromJoondalup,theDistanceInMetersFromArmadale)
to return the closest city, though now I would like to return the second and third closest city.
I haven't been able to get this to work as yet though I'm thinking something along the lines of:
citiesArray - closestCity = SecondClosestCitiesArray
then do a secondClosestCity = min(SecondClosestCitiesArray) to get the second closest city.
Then repeat this to find the third closest?
Any ideas?

You can add these value into an array and while adding it, make sure that they are getting added to sorting order. The array at any given point will give you closest city on the first index and second closest city on the second index.
Here is an example :
extension Array where Element == Double {
mutating func appendSorted(_ element: Double) {
if self.count == 0 {
self.append(element)
return
}
for i in 0..<self.count {
if element < self[i] {
self.insert(element, at: i)
return
}
}
self.append(element)
}
}
I am trying to show Invisible characters using below class & func, and it is working fine.
But replaceGlyphAtIndex is deprecated in OS X 10.11 and we need to use setGlyhs()
setGlyphs(<#T##glyphs: UnsafePointer<CGGlyph>##UnsafePointer<CGGlyph>#>, properties: <#T##UnsafePointer<NSGlyphProperty>#>, characterIndexes: <#T##UnsafePointer<Int>#>, font: <#T##NSFont#>, forGlyphRange: <#T##NSRange#>)
But i am having difficulties on how to convert replaceGlyphAtIndex to setGlyphs.
Can any one suggest me how to convert below replaceGlyphAtIndex to setGlyphs()?
I tried as below but it is crashing.
let data = String(g).dataUsingEncoding(NSUTF8StringEncoding)
let cgG = UnsafePointer<CGGlyph>(data!.bytes)
self.setGlyphs(cgG, properties: nil, characterIndexes: UnsafePointer<Int>(bitPattern: characterIndex), font: font as! NSFont, forGlyphRange: NSMakeRange(glyphIndex, 1))
Can any one let me know whats going wrong in the above line of code?
class MyLayoutManager: NSLayoutManager {
override func drawGlyphsForGlyphRange(glyphsToShow: NSRange, atPoint origin: NSPoint) {
if let storage = self.textStorage {
let s = storage.string
let startIndex = s.startIndex
for glyphIndex in glyphsToShow.location ..< glyphsToShow.location + glyphsToShow.length {
let characterIndex = self.characterIndexForGlyphAtIndex(glyphIndex)
let ch = s[startIndex.advancedBy(characterIndex)]
switch ch {
case " ": //Blank Space
let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
if let font = attrs[NSFontAttributeName] {
let g = font.glyphWithName("period")//("periodcentered")
self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)
// let data = String(g).dataUsingEncoding(NSUTF8StringEncoding)
// let cgG = UnsafePointer<CGGlyph>(data!.bytes)
//
// self.setGlyphs(cgG, properties: nil, characterIndexes: UnsafePointer<Int>(bitPattern: characterIndex), font: font as! NSFont, forGlyphRange: NSMakeRange(glyphIndex, 1))
}
case "\n": //New Line
let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
if let font = attrs[NSFontAttributeName] {
let g = font.glyphWithName("logicalnot")
self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)
}
case newLineUniCodeStr:
let attrs = storage.attributesAtIndex(characterIndex, effectiveRange: nil)
if let font = attrs[NSFontAttributeName] {
let g = font.glyphWithName("logicalnot")
self.replaceGlyphAtIndex(glyphIndex, withGlyph: g)
}
default:
break
}
}
}
super.drawGlyphsForGlyphRange(glyphsToShow, atPoint: origin)
}
}
I found another way to display Glyphs. (Posting my code below as it may be useful to others)
override func drawGlyphsForGlyphRange(glyphsToShow: NSRange, atPoint origin: NSPoint) {
if let storage = self.textStorage {
let s = storage.string
let startIndex = s.startIndex
var padding:CGFloat = 0
for glyphIndex in glyphsToShow.location ..< glyphsToShow.location + glyphsToShow.length {
let characterIndex = self.characterIndexForGlyphAtIndex(glyphIndex)
if characterIndex < s.characters.count
{
var glyphStr = ""
let ch = s[startIndex.advancedBy(characterIndex)]
switch ch {
case " ": //Blank Space
glyphStr = periodCenteredUniCodeStr
case "\n": //New Line
glyphStr = lineBreakUniCodeStr
case newLineUniCodeStr:
glyphStr = lineBreakUniCodeStr
padding += 5
default:
break
}
var glyphPoint = self.locationForGlyphAtIndex(glyphIndex)
let glyphRect = self.lineFragmentRectForGlyphAtIndex(glyphIndex, effectiveRange: nil)
if glyphStr.characters.count > 0{
glyphPoint.x = glyphPoint.x + glyphRect.origin.x
glyphPoint.y = glyphRect.origin.y
NSString(string: glyphStr).drawInRect(NSMakeRect(glyphPoint.x, glyphPoint.y, 10, 10), withAttributes: nil)
}
}else{
print("Wrong count here")
}
}
}
super.drawGlyphsForGlyphRange(glyphsToShow, atPoint: origin)
}
I'm trying to make an app, where you get buses positions from web API. When I got the data, I put annotations on mapview for all of the coordinates i got from API. Then, when annotation is tapped on, I try to hide all the annotations which aren't on the same route as the one clicked. It works fine, but when I zoom out the annotations that weren't in the original region aren't hidden. Is there a way to refresh what is displayed when user zooms on map view?

I am using this lib for drawChart. Link: https://github.com/danielgindi/Charts
THis is my code. When i draw only CandleChart, it is OK.
But when I try to draw CombinedChart. I receiver this result.
This is my result
#IBOutlet weak var chart: CombinedChartView!

var open = [Double]()
var high = [Double]()
var low = [Double]()

chart.pinchZoomEnabled = false
let xAxis = chart.xAxis
xAxis.labelPosition = ChartXAxis.XAxisLabelPosition.Bottom
xAxis.spaceBetweenLabels = 15

let leftAxis = chart.leftAxis
leftAxis.labelCount = 7

Please help me :)
Please take a look at the ChartsDemo which is part of the library, there is combined chart for your reference.
