iphone - 在 iOS 6.0 中打开 Apple map 并立即开始从当前位置到家的路线

Question

我想在我的应用程序中创建一个基本上标记为“带我回家”的链接。按下时，我希望它打开 Apple map ，从当前位置到家的路线，并开始逐向导航。

我找到了这个方案，但它并没有完成我所希望的一切:

http://maps.apple.com/maps?saddr=%f,%f&daddr=%f,%f

Answer 1

这是打开带有路线的 map 的工作代码(包括显示适用于 iOS5 的 Google map 的选项)

-(IBAction)showMapApp:(id)sender
{

CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(self.location.latitude,self.location.longitude);

//create MKMapItem out of coordinates
MKPlacemark* placeMark = [[MKPlacemark alloc] initWithCoordinate:coordinate addressDictionary:nil];
MKMapItem* destination =  [[MKMapItem alloc] initWithPlacemark:placeMark];

if([destination respondsToSelector:@selector(openInMapsWithLaunchOptions:)])
{
    //using iOS6 native maps app
    if(_mode == 1)
    {
        [destination openInMapsWithLaunchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeWalking}];

    }
    if(_mode == 2)
    {
        [destination openInMapsWithLaunchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving}];

    }
    if(_mode == 3)
    {
        [destination openInMapsWithLaunchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving}];

    }

} else{

    //using iOS 5 which has the Google Maps application
    NSString* url = [NSString stringWithFormat: @"http://maps.google.com/maps?saddr=Current+Location&daddr=%f,%f", self.location.latitude, self.location.longitude];
    [[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];
}
}
