زمان رسیدن به مقصد بعدی
برای دریافت زمان به مقصد بعدی، timeToNextDestination() را فراخوانی کنید. این مقدار NSTimeInterval را برمی گرداند. مثال زیر ثبت زمان رسیدن به مقصد بعدی را نشان می دهد:
سویفت
ifletnavigator=mapView.navigator{lettime=navigator.timeToNextDestinationletminutes=floor(time/60)letseconds=round(time-minutes*60)NSLog("Time to next destination: %.0f:%.0f",minutes,seconds)}
هدف-C
NSTimeIntervaltime=_mapView.navigator.timeToNextDestination;intminutes=floor(time/60);intseconds=round(time-minutes*60);NSLog(@"%@",[NSStringstringWithFormat:@"Time to next destination: %i:%i.",minutes,seconds]);
فاصله گرفتن تا مقصد بعدی
برای دریافت فاصله تا مقصد بعدی، distanceToNextDestination() را فراخوانی کنید. این یک مقدار CLLocationDistance را برمی گرداند. واحدها بر حسب متر مشخص می شوند.
سویفت
ifletnavigator=mapView.navigator{letdistance=navigator.distanceToNextDestinationletmiles=distance*0.00062137NSLog("Distance to next destination: %.2f miles.",miles)}
هدف-C
CLLocationDistancedistance=_mapView.navigator.distanceToNextDestination;doublemiles=distance*0.00062137;NSLog(@"%@",[NSStringstringWithFormat:@"Distance to next destination: %.2f.",miles]);
رسیدن به شرایط ترافیکی به مقصد بعدی
برای دریافت مقداری که جریان ترافیک به مقصد بعدی را نشان میدهد، delayCategoryToNextDestination فراخوانی کنید. این پارامتر GMSNavigationDelayCategory را برمی گرداند. مثال زیر ارزیابی نتیجه و ثبت یک پیام ترافیک را نشان می دهد:
سویفت
ifletnavigator=mapView.navigator{// insert sample for evaluating traffic valueletdelay=navigator.delayCategoryToNextDestinationlettraffic="unavailable"switchdelay{case.noData:traffic="unavailable"case.heavy:traffic="heavy"case.medium:traffic="moderate"case.light:traffic="light"default:traffic="unavailable"}print("Traffic is \(traffic).")}
هدف-C
GMSNavigationDelayCategorydelay=mapView.navigator.delayCategoryToNextDestination;NSString*traffic=@"";switch(delayCategory){caseGMSNavigationDelayCategoryNoData:traffic=@"No Data";break;caseGMSNavigationDelayCategoryHeavy:traffic=@"Heavy";break;caseGMSNavigationDelayCategoryMedium:traffic=@"Medium";break;caseGMSNavigationDelayCategoryLight:traffic=@"Light";break;default:NSLog(@"Invalid delay category: %zd",delayCategory);}NSLog(@"%@",[NSStringstringWithFormat:@"Traffic is %@.",traffic]);
دریافت اطلاعات در مورد پای فعلی
برای دریافت اطلاعات در مورد مسیر فعلی، با currentRouteLeg تماس بگیرید. این یک نمونه GMSRouteLeg را برمی گرداند که از آن می توانید دریافت کنید:
مقصد برای پا.
مختصات نهایی در ساق پا.
مسیری که شامل مختصاتی است که پای مسیر را تشکیل می دهد.
مثال زیر ثبت مختصات عنوان و lat/lng را برای قسمت بعدی مسیر نشان می دهد:
برای دریافت آخرین مسیر طی شده، با traveledPath تماس بگیرید. این یک نمونه GMSPath را برمی گرداند که برای حذف نقاط اضافی ساده شده است (به عنوان مثال تبدیل نقاط خطی متوالی به یک پاره خط منفرد). این مسیر تا شروع راهنمایی خالی است. مثال زیر دریافت آخرین مسیر طی شده را نشان می دهد:
سویفت
ifletnavigator=mapView.navigator{letlatestPath=navigator.traveledPathiflatestPath.count() > 0{letbegin:CLLocationCoordinate2D=latestPath.coordinate(at:0)letcurrent:CLLocationCoordinate2D=latestPath.coordinate(at:latestPath.count()-1)print("Path from (\(begin.latitude),\(begin.longitude)) to (\(current.latitude),\(current.longitude))")}}
هدف-C
GMSPath*latestPath=mapView.navigator.traveledPath;if(latestPath.count > 0){CLLocationCoordinate2Dbegin=[latestPathcoordinateAtIndex:0];CLLocationCoordinate2Dcurrent=[latestPathcoordinateAtIndex:latestPath.count-1];NSLog(@"Path from %f/%f to %f/%f",begin.latitude,begin.longitude,current.latitude,current.longitude);}
