如何在iOS 6中启动具有特定地址的iOS Maps App？ [英] How to launch iOS Maps App with specific address in iOS 6?

问题描述

我有一个应用程序，允许用户启动Google地图应用程序（Google或Apple）查看地址。 我曾经这样做过：

p>

  Address * address = [self.person.addresses objectAtIndex：0]; 
 
 NSString * addressString = [NSString stringWithFormat：@％@％@％@％@，％@％@，
 address.line1 == nil？ @：address.line1，
 address.line2 == nil？ @：address.line2，
 address.line3 == nil？ @：address.line3，
 address.city == nil？ @：address.city，
 address.state == nil？ @：address.state，
 address.zip == nil？ @：address.zip]; 
 
 NSString * mapsURL = [NSString stringWithFormat：@http://maps.google.com/maps?q=%@，[addressString stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]]; 
 
 [[UIApplication sharedApplication] openURL：[NSURL URLWithString：mapsURL]]; 
  

但是为了支持iOS 6，我将其更改为：

  Address * address = [self.person.addresses objectAtIndex：0]; 
 
 NSString * addressString = [NSString stringWithFormat：@％@％@％@％@，％@％@，
 address.line1 == nil？ @：address.line1，
 address.line2 == nil？ @：address.line2，
 address.line3 == nil？ @：address.line3，
 address.city == nil？ @：address.city，
 address.state == nil？ @：address.state，
 address.zip == nil？ @：address.zip]; 
 
 //检查iOS 6 
类mapItemClass = [MKMapItem class]; 
 if（mapItemClass&& [mapItemClass respondsToSelector：@selector（openMapsWithItems：launchOptions :)]）
 {
 / * 
 //创建一个MKMapItem传递给地图app 
 MKPlacemark * placemark = [[MKPlacemark alloc] initWithCoordinate：nil 
 addressDictionary：nil]; 
 
 MKMapItem * mapItem = [[MKMapItem alloc] initWithPlacemark：placemark]; 
 [mapItem openInMapsWithLaunchOptions：nil]; 
 * / 
 
 //我想要的是这样的：
 MKMapItem * mapItem = [[MKMapItem alloc] initWithAddressQuery：addressString]; 
 [mapItem openInMapsWithLaunchOptions：nil]; 
} 
 else 
 {
 NSString * mapsURL = [NSString stringWithFormat：@http://maps.google.com/maps?q=%@，[addressString stringByAddingPercentEscapesUsingEncoding ：NSUTF8StringEncoding]]; 
 
 [[UIApplication sharedApplication] openURL：[NSURL URLWithString：mapsURL]]; 
 
 
 $ / code> 

基本上，用原始地址（no ABPersonRef 的或任何东西）我需要在Apple Maps中打开位置。 Google曾经这样做很好。



我尝试了从 maps.google.com 到地图的简单切换。 apple.com ，但在iOS 5中打开Goog​​le Maps网络应用程序 - 我不想！有一个非常好的本地应用程序。

解决方案

找到答案此处。它通过使用 CLGeocoder 类来完成：



  //检查iOS 6 
类mapItemClass = [MKMapItem class]; 
 if（mapItemClass&& [mapItemClass respondsToSelector：@selector（openMapsWithItems：launchOptions :)]）
 {
 CLGeocoder * geocoder = [[CLGeocoder alloc] init]; 
 [geocoder geocodeAddressString：addressString 
 completionHandler：^（NSArray * placemarks，NSError * error）{
 
 //将CLPlacemark转换为MKPlacemark 
 //注意：检查失败的地理编码没有错误
 CLPlacemark * geocodedPlacemark = [placemarks objectAtIndex：0]; 
 MKPlacemark * placemark = [[MKPlacemark alloc] 
 initWithCoordinate：geocodedPlacemark.location.coordinate 
 addressDictionary：geocodedPlacemark.addressDictionary]; 
 
 //创建地图项以传递给地图应用的地理编码地址
 MKMapItem * mapItem = [[MKMapItem alloc] initWithPlacemark：placemark]; 
 [mapItem setName：geocodedPlacemark.name]; 
 
 //将方向模式设置为驾驶
 //可以使用MKLaunchOptionsDirectionsModeWalking来代替
 NSDictionary * launchOptions = @ {MKLaunchOptionsDirectionsModeKey：MKLaunchOptionsDirectionsModeDriving}; 
 
 //获取当前用户位置MKMapItem 
 MKMapItem * currentLocationMapItem = [MKMapItem mapItemForCurrentLocation]; 
 
 //将当前位置和目标地图项目传递给地图应用程序
 //在launchOptions字典中设置方向模式
 [MKMapItem openMapsWithItems：@ [currentLocationMapItem，mapItem] launchOptions：launchOptions]; 
 
}]; 
} 
 // iOS 4/5：
 else 
 {
 NSString * mapsURL = [NSString stringWithFormat：@http://maps.google.com/ maps？q =％@，[addressString stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]]; 
 ... 
  




I have an app in which I allow users to launch the Maps App (Google or Apple) to view an address.

I used to do this:

Address *address = [self.person.addresses objectAtIndex:0]; 

NSString *addressString = [NSString stringWithFormat:@"%@ %@ %@ %@, %@ %@",
                                   address.line1 == nil ? @"" : address.line1,
                                   address.line2 == nil ? @"" : address.line2,
                                   address.line3 == nil ? @"" : address.line3,
                                   address.city == nil ? @"" : address.city,
                                   address.state == nil ? @"" : address.state,
                                   address.zip == nil ? @"" : address.zip];

NSString *mapsURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", [addressString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mapsURL]];

But to support iOS 6, I've changed it to this:

Address *address = [self.person.addresses objectAtIndex:0]; 

        NSString *addressString = [NSString stringWithFormat:@"%@ %@ %@ %@, %@ %@",
                                   address.line1 == nil ? @"" : address.line1,
                                   address.line2 == nil ? @"" : address.line2,
                                   address.line3 == nil ? @"" : address.line3,
                                   address.city == nil ? @"" : address.city,
                                   address.state == nil ? @"" : address.state,
                                   address.zip == nil ? @"" : address.zip];

        // Check for iOS 6
        Class mapItemClass = [MKMapItem class];
        if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)])
        {
            /*
            // Create an MKMapItem to pass to the Maps app
            MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:nil
                                                           addressDictionary:nil];

            MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark];
            [mapItem openInMapsWithLaunchOptions:nil];
            */

            // I want something like this:
            MKMapItem *mapItem = [[MKMapItem alloc] initWithAddressQuery:addressString];
            [mapItem openInMapsWithLaunchOptions:nil];
        }
        else
        {
            NSString *mapsURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", [addressString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:mapsURL]];

        }

Basically, with the raw address (no ABPersonRef's or anything) I need to open the location in Apple Maps. Google used to do this just fine.

I've tried the simple switch from maps.google.com to maps.apple.com but in iOS 5 it opens to Google Maps web app -- which I don't want! There's a perfectly good native app.

解决方案

Found the answer here. It is accomplished by using the CLGeocoder class:

// Check for iOS 6
    Class mapItemClass = [MKMapItem class];
    if (mapItemClass && [mapItemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)])
    {
        CLGeocoder *geocoder = [[CLGeocoder alloc] init];
        [geocoder geocodeAddressString:addressString
                     completionHandler:^(NSArray *placemarks, NSError *error) {

                         // Convert the CLPlacemark to an MKPlacemark
                         // Note: There's no error checking for a failed geocode
                         CLPlacemark *geocodedPlacemark = [placemarks objectAtIndex:0];
                         MKPlacemark *placemark = [[MKPlacemark alloc]
                                                   initWithCoordinate:geocodedPlacemark.location.coordinate
                                                   addressDictionary:geocodedPlacemark.addressDictionary];

                         // Create a map item for the geocoded address to pass to Maps app
                         MKMapItem *mapItem = [[MKMapItem alloc] initWithPlacemark:placemark];
                         [mapItem setName:geocodedPlacemark.name];

                         // Set the directions mode to "Driving"
                         // Can use MKLaunchOptionsDirectionsModeWalking instead
                         NSDictionary *launchOptions = @{MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving};

                         // Get the "Current User Location" MKMapItem
                         MKMapItem *currentLocationMapItem = [MKMapItem mapItemForCurrentLocation];

                         // Pass the current location and destination map items to the Maps app
                         // Set the direction mode in the launchOptions dictionary
                         [MKMapItem openMapsWithItems:@[currentLocationMapItem, mapItem] launchOptions:launchOptions];

                     }];
    }
    //iOS 4/5:
    else
    {
        NSString *mapsURL = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", [addressString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
        ...
