最近项目关于地图的,和朋友一起做的,他们用的高德地图,他做到半路有事,我来接手,结果我手机上没有安装高德地图,到我这边点击导航没啥反应,后来就查了一下,简单处理下,最终实现以下的需求:
点击导航,底部弹框,显示用户设备上所有的地图(一般就苹果自带的地图、百度地图、高德地图,当然了还有其他地图,个人感觉就这几个用的人比较多,其他的其实也类似)

具体做法如下:

  1. plist文件进行相关的配置
    LSApplicationQueriesSchemes (这个一定不要写错,一定不要写错,一定不要写错,这个我是有教训的,说多了都是泪)这是一个数组,可以添加各地图的相关url Scheme
    常见的地图对应如下:
    百度地图:baidumap
    高德地图:iosamap
    谷歌地图:comgooglemaps
    腾讯地图:qqmap

你也可以直接直接复制以下代码到plist文件

<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>baidumap</string>
        <string>iosamap</string>
        <string>comgooglemaps</string>
        <string>qqmap</string>
    </array>

2.使用系统的API判断设备是否安装相关的地图应用程序

- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);

具体写发如下:

百度地图

 [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]

高德地图

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]

谷歌地图

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]

腾讯地图

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]

该方法返回的bool值即可判断该设备有没有安装相关的地图应用
备注:苹果自带的地图是不需要判断的

这里贴一段代码,需要的时候稍微修改下即可

-(void)doNavigationWithEndLocation:(NSArray *)endLocation
{
    NSMutableArray *maps = [NSMutableArray array];
    //苹果原生地图-苹果原生地图方法和其他不一样
    NSMutableDictionary *iosMapDic = [NSMutableDictionary dictionary];
    iosMapDic[@"title"] = @"苹果地图";
    [maps addObject:iosMapDic];
    //百度地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        NSMutableDictionary *baiduMapDic = [NSMutableDictionary dictionary];
        baiduMapDic[@"title"] = @"百度地图";
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%@,%@|name=北京&mode=driving&coord_type=gcj02",endLocation[0],endLocation[1]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        baiduMapDic[@"url"] = urlString;
        [maps addObject:baiduMapDic];
    }
    
    //高德地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
        gaodeMapDic[@"title"] = @"高德地图";
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%@&lon=%@&dev=0&style=2",@"导航功能",@"nav123456",endLocation[0],endLocation[1]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        gaodeMapDic[@"url"] = urlString;
        [maps addObject:gaodeMapDic];
    }
    
    //谷歌地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
        NSMutableDictionary *googleMapDic = [NSMutableDictionary dictionary];
        googleMapDic[@"title"] = @"谷歌地图";
        NSString *urlString = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=&daddr=%@,%@&directionsmode=driving",@"导航测试",@"nav123456",endLocation[0], endLocation[1]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        googleMapDic[@"url"] = urlString;
        [maps addObject:googleMapDic];
    }
    
    //腾讯地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {
        NSMutableDictionary *qqMapDic = [NSMutableDictionary dictionary];
        qqMapDic[@"title"] = @"腾讯地图";
        NSString *urlString = [[NSString stringWithFormat:@"qqmap://map/routeplan?from=我的位置&type=drive&tocoord=%@,%@&to=终点&coord_type=1&policy=0",endLocation[0], endLocation[1]] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        qqMapDic[@"url"] = urlString;
        [maps addObject:qqMapDic];
    }
    
    //选择
    UIAlertController * alert = [UIAlertController alertControllerWithTitle:@"选择地图" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    
    NSInteger index = maps.count;
    
    for (int i = 0; i < index; i++) {
        
        NSString * title = maps[i][@"title"];
        //苹果原生地图方法
        if (i == 0) {
            UIAlertAction * action = [UIAlertAction actionWithTitle:title style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
                [self navAppleMapnavAppleMapWithArray:endLocation];
            }];
            [alert addAction:action];
            continue;
        }
        
        UIAlertAction * action = [UIAlertAction actionWithTitle:title style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSString *urlString = maps[i][@"url"];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
        }];
        
        [alert addAction:action];
    }
    
    UIAlertAction * action = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
        
    }];
    
    [alert addAction:action];
    
    [[CPBaseViewController getCurrentVC] presentViewController:alert animated:YES completion:nil];
//    [self presentViewController:alert animated:YES completion:nil];
    
}

//苹果地图
- (void)navAppleMapnavAppleMapWithArray:(NSArray*) array
{
    float lat = [NSString stringWithFormat:@"%@", array[0]].floatValue;
    float lon = [NSString stringWithFormat:@"%@", array[1]].floatValue;
    //终点坐标
    CLLocationCoordinate2D loc = CLLocationCoordinate2DMake(lat, lon);
    
    //用户位置
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    //终点位置
    MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:loc addressDictionary:nil] ];
    
    NSArray *items = @[currentLoc,toLocation];
    //第一个
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    //第二个,都可以用
    //    NSDictionary * dic = @{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,
    //                           MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]};
    
    [MKMapItem openMapsWithItems:items launchOptions:dic];
    
}

使用记得导入需要的头文件,比如苹果自带地图

import <MapKit/MapKit.h>

...

备注:
-(void)doNavigationWithEndLocation:(NSArray *)endLocation;该方法中的数组传的其实就是经纬度,到时候根据自己的需求修改下就可以直接使用

基本的使用就只这样,希望可以帮到有需求的小伙伴。。。
