http://maps.apple.com/maps?saddr=%f,%f&daddr=%f,%f 会提示无法定位,不知道为什么?
使用maps://saddr=%f,%f&daddr=%f,%f 会找不到当前位置,也不清楚原因?
不过还是找到了解决方法,如下(包括两种地图调用方式):
if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下,调用google map
NSString *urlString = [[NSString alloc]
initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",
cutLat,cutLon,stationLat,stationLon];
NSURL *aURL = [NSURL URLWithString:urlString];
[urlString release];
[[UIApplication sharedApplication] openURL:aURL];
} else { // 直接调用ios自己带的apple map
CLLocationCoordinate2D to;
to.latitude = stationLat;
to.longitude = stationLon;
MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[[MKPlacemark alloc] initWithCoordinate:to addressDictionary:nil] autorelease]];
toLocation.name = @"Destination";
[MKMapItem openMapsWithItems:[NSArray arrayWithObjects:currentLocation, toLocation, nil]
launchOptions:[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:MKLaunchOptionsDirectionsModeDriving, [NSNumber numberWithBool:YES], nil]
forKeys:[NSArray arrayWithObjects:MKLaunchOptionsDirectionsModeKey, MKLaunchOptionsShowsTrafficKey, nil]]];
[toLocation release];
}
记得加上:
#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
