我想在iOS默认Map App中的两个位置之间实现get direction功能,我试过这个
Class itemClass = [MKMapItem class];
if (itemClass && [itemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) {
// Use iOS 6 maps
NSString *latString = @"23.0300";
NSString *longString = @"72.5800";
CLLocationCoordinate2D ctrpoint;
ctrpoint.latitude = [latString doubleValue];
ctrpoint.longitude = [longString doubleValue];
MKPlacemark *placemark2 = [[MKPlacemark alloc] initWithCoordinate:ctrpoint addressDictionary:nil];
MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark2];
[mapItem openInMapsWithLaunchOptions:nil];
}

但它显示方向错误如下:
我甚至打开了地图应用程序,找到了我当前的位置,在离我所在位置最近的地图上添加了一个图钉,并且获取方向仍然无效.
此外,"总之,即使在本机应用程序中,Get Direction也无法正常工作"任何人都可以帮助我实现这一目标吗?

Apple Maps不支持印度的路线.
您可以使用谷歌地图获取路线,如果它在手机上可用.如果谷歌地图应用程序无法使用Apple地图.
以下代码块可能会有所帮助.
NSURL *appUrl;
//Is Google Maps App Installed ?
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
// Use Google Maps App to get Directions
appUrl = [NSURL URLWithString:[NSString stringWithFormat:@"comgooglemaps://?daddr=%f,%f&saddr=%f,%f",
destLocation.coordinate.latitude, destLocation.coordinate.longitude,
_currentLocation.coordinate.latitude,_currentLocation.coordinate.longitude]];
}
// Google Maps not Installed
else {
// Use Apple Maps App to get Directions
appUrl = [NSURL URLWithString:[NSString stringWithFormat:@"http://maps.apple.com/?daddr=%f,%f&saddr=%f,%f",
destLocation.coordinate.latitude, destLocation.coordinate.longitude,
_currentLocation.coordinate.latitude,_currentLocation.coordinate.longitude]];
}
[[UIApplication sharedApplication] openURL:appUrl];
