前言

术语：

1. 应用外导航：是指以URL跳转的方式(在iOS中就是以URL Scheme的方式)，直接跳到对应的地图APP中，直接利用对方的功能来导航。这样的优点，一是接入方便，二是不增加自己APP的开销。
2. 应用内导航：是指使用地图服务提供的SDK(如高德,百度)，直接将导航功能嵌入到我们自己的APP内部。

需求：跳转到已经安装的地图
背景：为了减少app内存开支，以URI跳转的方式直接跳转到对应的地图进行导航，让最专业的人做最专业的事。

I 开发步骤

1.1 添加Scheme白名单

iOS 9 之后涉及到app跳转时，系统会自动到项目info.plist下检测是否设置相关平台Scheme。

<!--具体方法：在项目的info.plist中添加LSApplicationQueriesSchemes字段，类型是Array，然后添加Item。-->
    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>baidumap</string>
        <string>iosamap</string>
        <string>comgooglemaps</string>
        <string>qqmap</string>
    </array>

苹果自带地图： if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"http://maps.apple.com/"]]) {

百度地图 ：baidumap://

高德地图 ：iosamap://

谷歌地图： comgooglemaps://

腾讯地图：qqmap://

1.2 检测是否安装相应APP

使用canOpenURL:方法来检测该手机是否安装相应APP

- (void)showSheet
{
    NSString * appleMap  = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"http://maps.apple.com/"]] ? @"苹果地图" : nil;
    
    NSString * baiduMap  = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]] ? @"百度地图" : nil;
    NSString * gaodeMap  = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]] ? @"高德地图":nil;
    //谷歌地图:不能用，需翻_墙
    NSString * googleMap = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]] ? nil :nil;
    //
    NSString * tencentMap  = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://map/"]] ? nil : nil;
    
    
    UIActionSheet * actionSheet = [[UIActionSheet alloc] initWithTitle:@"请选择您已经安装的导航工具" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:gaodeMap otherButtonTitles:appleMap,baiduMap,tencentMap,nil];//googleMap
    [actionSheet showInView:[UIApplication sharedApplication].keyWindow];
}

1.3 封装跳转URL

1. 地址系列

    //    //腾讯,type=bus 或 type=drive 或 type=walk 或 type=bike referer开发者key:
    NSString * tencentAddressUrl = [[NSString stringWithFormat:@"qqmap://map/routeplan?type=walk&from=%@&to=%@&policy=1&referer=%@",mb.start, mb.end,_appName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    //苹果
    NSString *appleAddressUrl = [[NSString stringWithFormat:@"http://maps.apple.com/?saddr=%@&daddr=%@&dirflg=w",_start, mb.end] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    
    //百度
    NSString *baiduAddressUrl = [[NSString stringWithFormat:@"baidumap://map/direction?origin=%@&destination=%@&mode=walking&region=%@&src=%@",mb.start, mb.end,_city,_appName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    //高德
    NSString *gaodeAddressUrl = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&sid=BGVIS1&sname=%@&did=BGVIS2&dname=%@&dev=0&m=2&t=2",_appName,mb.start,mb.end] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    //谷歌
    NSString *googleAddressUrl = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=%@&daddr=%@&directionsmode=bicycling",_appName,_urlScheme,mb.start, mb.end] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    

1. 通过经纬度参数打开

    NSString * baiduUrlStr = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name=目的地&mode=driving&coord_type=gcj02",mb.Coordinate2D.latitude, mb.Coordinate2D.longitude] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    
    NSString * goooleUrlStr = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=&daddr=%f,%f&directionsmode=driving",_appName,_urlScheme,mb.Coordinate2D.latitude, mb.Coordinate2D.longitude] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
    
    NSString * gaodeUrlStr= [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",_appName,_urlScheme,mb.Coordinate2D.latitude, mb.Coordinate2D.longitude] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

1. 方便弹回来

为了能够跳转回的自己的APP，需要在 URL Types里填写你的app的 URL Schemes

II 代码封装

完整代码获取，请联系我：#公号：iOS逆向。

2.1 API

#import <MapKit/MKMapItem.h>//用于苹果自带地图

#import <MapKit/MKTypes.h>//用于苹果自带地图

/**
 地图类型
 */
typedef enum : NSUInteger {
    k_MapSelect4Apple = 0,
    k_MapSelect4Baidu,
    k_MapSelect4Google,
    k_MapSelect4Gaode,
    k_MapSelect4Tencent
} k_MapSelect;

/**
 跳转URL的参数类型
 */
typedef enum : NSUInteger {
    /**
     地址
     */
    k_MapNavStyle4Address = 0,
    /**
     经纬度
     */
    k_MapNavStyle4Coordinates
} k_MapNavStyle;


@interface MapNavigationManager : NSObject

+ (void)showSheetWithCity:(NSString *)city start:(NSString *)start end:(NSString *)end;
+ (void)showSheetWithCoordinate2D:(CLLocationCoordinate2D)Coordinate2D;

@end

用法

            NSString *start = @"";            
            [ERPMapNavManager showSheetWithCity:self.models.delivery.cityName start:start end:self.models.delivery.address];
            

2.2 核心实现

    NSString * urlString = [self getUrlStr:index];
    if (urlString != nil) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    }

2.3 注意事项

1. 腾讯地图需要给默认开始位置:https://lbs.qq.com/webApi/uriV1/uriGuide/uriMobileGuide

    NSString *start = mb.start.length>0 ?mb.start :@"我的位置";

1. 创建UIActionSheet时，otherButtonTitles参数最多支持3个，因为推荐使用UIAlertController。

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"请选择您已经安装的导航工具" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    __weak __typeof__(self) weakSelf = self;

    
    if(gaodeMap){
        UIAlertAction *action = [UIAlertAction actionWithTitle:gaodeMap style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
            
            
            NSString * urlString = [self getUrlStr:k_MapSelect4Gaode];
            
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

        }];

        [alert addAction:action];
    }
    
    if(appleMap){
        UIAlertAction *action = [UIAlertAction actionWithTitle:appleMap style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
            
            if(weakSelf.style == k_MapNavStyle4Coordinates)
                
            {
                MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
                MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:self.Coordinate2D addressDictionary:nil]];
                [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
                               launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
                return;
            }
            
            NSString * urlString = [self getUrlStr:k_MapSelect4Apple];
            
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

        }];

        [alert addAction:action];
    }
    
    
    
    UIAlertAction *action = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
    [alert addAction:action];

    [[QCT_Common getCurrentVC] presentViewController:alert animated:YES completion:^{
        
    }];
