我怎么才能从A到B的Xcode中找到iPhone ios6应用的方向呢?

I want to update an app from iOS < 6 that uses Google Maps. My app has a lot of pins on a map, and, when a user taps over one of them, the iPhone call Maps like a shared application to get direction from his current location and the destination with the native Maps App. With iOS 6, the same instructions (posted below) obviously open Safari instead Google Maps. I want to write an if-cycle that checks the iOS installed on the device: if < 6, nothing changed, if iOS > 6 then..... (open new apple maps and get direction there).

我想更新一个iOS < 6中使用谷歌地图的应用。我的程序有很多地图上的别针,,当一个用户在其中一个水龙头,iPhone电话像一个共享的应用程序映射到获取当前位置和目标方向与本地地图应用。iOS 6,相同的指令(发布)显然开放Safari而不是谷歌地图。我想写一个if-cycle，检查设备上安装的iOS: if < 6，没有变化，如果iOS > 6，则……(打开新的苹果地图，找到那里的方向)。

Someone can help me please?

有人能帮我吗?

Here the Action before iOS 6

这里是iOS 6之前的动作

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {

    [self.navigationController pushViewController:[[UIViewController alloc] init] animated:YES];


    NSString* addr = [NSString stringWithFormat:@"http://maps.google.com/maps?daddr=%1.6f,%1.6f&saddr=Posizione attuale", view.annotation.coordinate.latitude,view.annotation.coordinate.longitude];

    NSURL* url = [[NSURL alloc] initWithString:[addr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];  
    [[UIApplication sharedApplication] openURL:url];



}

I recommend using [MKMapItem openMapsWithItems:] instead of opening the maps app via a URL in iOS 6. If you use a URL, you will not be able to pass "Current Location" and will lose the ability to do turn-by-turn navigation. MKMapItem has a specific item for current location that, when passed, will open Maps using Current Location as the source address thus enabling turn-by-turn navigation.

我建议使用[MKMapItem openMapsWithItems:]而不是通过ios6中的URL打开地图应用。如果您使用一个URL，您将不能通过“当前位置”，并且将失去进行逐转导航的能力。MKMapItem有一个针对当前位置的特定项，该项在传递时将使用当前位置作为源地址打开映射，从而支持逐向导航。

- (void)openMapsWithDirectionsTo:(CLLocationCoordinate2D)to {
    Class itemClass = [MKMapItem class];
    if (itemClass && [itemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) {
        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];
    } else {
        NSMutableString *mapURL = [NSMutableString stringWithString:@"http://maps.google.com/maps?"];
        [mapURL appendFormat:@"saddr=Current Location"];
        [mapURL appendFormat:@"&daddr=%f,%f", to.latitude, to.longitude];
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[mapURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
    }
}

I've used a preprocessor code like this one posted below to define my condition for the if cycle.

我使用了如下所示的预处理器代码来定义if循环的条件。

#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

Then:

然后:

if (SYSTEM_VERSION_LESS_THAN(@"6.0")) {
         NSString* addr = [NSString stringWithFormat:@"http://maps.google.com/maps?daddr=%1.6f,%1.6f&saddr=Posizione attuale", view.annotation.coordinate.latitude,view.annotation.coordinate.longitude];
         NSURL* url = [[NSURL alloc] initWithString:[addr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
         [[UIApplication sharedApplication] openURL:url];
    }

else {
        NSString* addr = [NSString stringWithFormat:@"http://maps.apple.com/maps?daddr=%1.6f,%1.6f&saddr=Posizione attuale", view.annotation.coordinate.latitude,view.annotation.coordinate.longitude];
        NSURL* url = [[NSURL alloc] initWithString:[addr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        [[UIApplication sharedApplication] openURL:url];


    }

It seems to work Bye !

看来要结束了!

The accepted answer didn't work for me. The Current Location needs to be in the correct language and also the ios6 version didn't load correctly. For me the following worked.

公认的答案对我不起作用。当前位置需要使用正确的语言，而且ios6版本没有正确加载。对我来说，以下方法是有效的。

NSString *destinationAddress = @"Amsterdam";

Class itemClass = [MKMapItem class];
if (itemClass && [itemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) {

    CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder geocodeAddressString:destinationAddress completionHandler:^(NSArray *placemarks, NSError *error) {
        if([placemarks count] > 0) {

            MKPlacemark *placeMark = [[MKPlacemark alloc] initWithPlacemark:[placemarks objectAtIndex:0]];

            MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:placeMark];

            MKMapItem *mapItem2 = [MKMapItem mapItemForCurrentLocation];


            NSArray *mapItems = @[mapItem, mapItem2];

            NSDictionary *options = @{
        MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,
        MKLaunchOptionsMapTypeKey:
            [NSNumber numberWithInteger:MKMapTypeStandard],
        MKLaunchOptionsShowsTrafficKey:@YES
            };

            [MKMapItem openMapsWithItems:mapItems launchOptions:options];

        } else {
            //error nothing found
        }
    }];
    return;
} else {

    NSString *sourceAddress = [LocalizedCurrentLocation currentLocationStringForCurrentLanguage];

    NSString *urlToOpen = [NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%@&daddr=%@",
                 [sourceAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
                 [destinationAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlToOpen]];
}

For ios5 I use the LocalizedCurrentLocation from this post http://www.martip.net/blog/localized-current-location-string-for-iphone-apps

对于ios5，我使用本文中的LocalizedCurrentLocation http://www.martip.net/blog/localized-current- localized- string-for iphone应用

For ios6 I use the CLGeocoder to get the placemark and then open the map with it and the current location.

对于ios6，我使用CLGeocoder获取placemark，然后用它和当前位置打开映射。

Remember to add CoreLocation.framework and MapKit.framework

记住要添加coreloc.framework和MapKit.framework
