পরবর্তী গন্তব্যে যাওয়ার সময় পাওয়া যাচ্ছে
পরবর্তী গন্তব্যে যাওয়ার সময় পেতে, timeToNextDestination() কল করুন। এটি একটি NSTimeInterval মান প্রদান করে। নিম্নলিখিত উদাহরণটি পরবর্তী গন্তব্যে লগ করার সময় দেখায়:
সুইফট
if let navigator = mapView.navigator {
let time = navigator.timeToNextDestination
let minutes = floor(time/60)
let seconds = round(time - minutes * 60)
NSLog("Time to next destination: %.0f:%.0f", minutes, seconds)
}
উদ্দেশ্য-C
NSTimeInterval time = _mapView.navigator.timeToNextDestination;
int minutes = floor(time/60);
int seconds = round(time - minutes * 60);
NSLog(@"%@", [NSString stringWithFormat:@"Time to next destination: %i:%i.", minutes, seconds]);
পরবর্তী গন্তব্যে দূরত্ব পাচ্ছি
পরবর্তী গন্তব্যের দূরত্ব পেতে, distanceToNextDestination() কল করুন। এটি একটি CLLocationDistance মান প্রদান করে। ইউনিট মিটারে নির্দিষ্ট করা হয়।
সুইফট
if let navigator = mapView.navigator {
let distance = navigator.distanceToNextDestination
let miles = distance * 0.00062137
NSLog("Distance to next destination: %.2f miles.", miles)
}
উদ্দেশ্য-C
CLLocationDistance distance = _mapView.navigator.distanceToNextDestination;
double miles = distance * 0.00062137;
NSLog(@"%@", [NSString stringWithFormat:@"Distance to next destination: %.2f.", miles]);
পরবর্তী গন্তব্যে ট্র্যাফিক পরিস্থিতি পাওয়া
পরবর্তী গন্তব্যে ট্রাফিকের প্রবাহ নির্দেশ করে এমন একটি মান পেতে, delayCategoryToNextDestination এ কল করুন। এই প্যারামিটারটি GMSNavigationDelayCategory প্রদান করে। নিম্নলিখিত উদাহরণটি ফলাফলের মূল্যায়ন এবং একটি ট্রাফিক বার্তা লগিং দেখায়:
সুইফট
if let navigator = mapView.navigator {
// insert sample for evaluating traffic value
let delay = navigator.delayCategoryToNextDestination
let traffic = "unavailable"
switch delay {
case .noData:
traffic = "unavailable"
case .heavy:
traffic = "heavy"
case .medium:
traffic = "moderate"
case .light:
traffic = "light"
default:
traffic = "unavailable"
}
print("Traffic is \(traffic).")
}
উদ্দেশ্য-C
GMSNavigationDelayCategory delay = mapView.navigator.delayCategoryToNextDestination;
NSString *traffic = @"";
switch (delayCategory) {
case GMSNavigationDelayCategoryNoData:
traffic = @"No Data";
break;
case GMSNavigationDelayCategoryHeavy:
traffic = @"Heavy";
break;
case GMSNavigationDelayCategoryMedium:
traffic = @"Medium";
break;
case GMSNavigationDelayCategoryLight:
traffic = @"Light";
break;
default:
NSLog(@"Invalid delay category: %zd", delayCategory);
}
NSLog(@"%@", [NSString stringWithFormat:@"Traffic is %@.", traffic]);
বর্তমান পা সম্পর্কে তথ্য পাওয়া
বর্তমান রুট লেগ সম্পর্কে তথ্য পেতে, currentRouteLeg এ কল করুন। এটি একটি GMSRouteLeg উদাহরণ প্রদান করে, যেখান থেকে আপনি পেতে পারেন:
পায়ের জন্য গন্তব্য।
পায়ে চূড়ান্ত স্থানাঙ্ক।
স্থানাঙ্ক ধারণকারী পাথ যা রুট লেগ তৈরি করে।
নিম্নলিখিত উদাহরণটি পরবর্তী রুট লেগের জন্য শিরোনাম এবং ল্যাট/এলএনজি স্থানাঙ্কগুলি লগিং দেখায়:
সুইফট
if let navigator = mapView.navigator {
let currentLeg = navigator.currentRouteLeg
let nextDestination = currentLeg?.destinationWaypoint?.title
let lat = currentLeg?.destinationCoordinate.latitude.description
let lng = currentLeg?.destinationCoordinate.longitude.description
NSLog(nextDestination! + ", " + lat! + "/" + lng!)
}
অতি সম্প্রতি ভ্রমণ করা পথ পেতে, traveledPath কল করুন। এটি একটি GMSPath উদাহরণ প্রদান করে যা অপ্রয়োজনীয় পয়েন্টগুলি সরানোর জন্য সরলীকৃত করা হয়েছে (উদাহরণস্বরূপ পরপর কলিনিয়ার পয়েন্টগুলিকে একটি একক লাইন বিভাগে পরিণত করা)। নির্দেশিকা শুরু না হওয়া পর্যন্ত এই পথটি খালি। নিম্নলিখিত উদাহরণটি দেখায় যে সাম্প্রতিক ভ্রমণের পথ পাওয়া যাচ্ছে:
সুইফট
if let navigator = mapView.navigator {
let latestPath = navigator.traveledPath
if latestPath.count() > 0 {
let begin: CLLocationCoordinate2D = latestPath.coordinate(at: 0)
let current: CLLocationCoordinate2D = latestPath.coordinate(at: latestPath.count() - 1)
print("Path from (\(begin.latitude),\(begin.longitude)) to (\(current.latitude),\(current.longitude))")
}
}
উদ্দেশ্য-C
GMSPath *latestPath = mapView.navigator.traveledPath;
if (latestPath.count > 0) {
CLLocationCoordinate2D begin = [latestPath coordinateAtIndex:0];
CLLocationCoordinate2D current = [latestPath coordinateAtIndex:latestPath.count - 1];
NSLog(@"Path from %f/%f to %f/%f",
begin.latitude,
begin.longitude,
current.latitude,
current.longitude);
