题

我想要在我的应用程序中创建一个链接，基本上将被标记为“带我回家”。按下时，我希望它打开Apple地图，从当前位置到家庭，然后通过转动导航开始转动。

我找到了这个方案，但它不做我希望的一切： 

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

有帮助吗？

解决方案

以下是使用路由打开地图的工作代码（包括为iOS5显示Google地图的选项） 

-(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]];
}
}
.

其他提示

对我来说，它的工作精细:: 

NSString* url = [NSString stringWithFormat: @"http://maps.apple.com/maps?saddr=44.521358,11.374080&daddr=44.518640,11.362665"];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: url]];
.
