iOS App内部调起百度地图、高德地图、腾讯地图

公司App集成的是百度地图,然后调起百度地图、高德地图、腾讯地图、苹果地图进行导航的功能.

一.首先需要在info.plist文件中添加白名单如下:

LSApplicationQueriesSchemes
    
        baidumap //百度
        iosamap //高德
        qqmap //腾讯
    

使用: [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"白名单://"]] 判断是否安装白名单里面的App.

二.由于项目继承的是百度地图,调用其他导航会有地理偏差,我们要进行坐标转换,可以使用这个转换工具.

第一种:调起苹果自带的地图进行导航:

苹果自带的地图不需要设置白名单,需要设置终点的经纬度就行,需要导入#import 头文件

//坐标转换
CLLocationCoordinate2D gcj02Coord = [JZLocationConverter bd09ToGcj02:loc];
    //用户位置
    MKMapItem *currentLoc = [MKMapItem mapItemForCurrentLocation];
    //终点位置
    MKMapItem *toLocation = [[MKMapItem alloc]initWithPlacemark:[[MKPlacemark alloc]initWithCoordinate:gcj02Coord addressDictionary:nil] ];
    toLocation.name = title;
    
    NSArray *items = @[currentLoc,toLocation];
    NSDictionary *dic = @{
                          MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving,
                          MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard),
                          MKLaunchOptionsShowsTrafficKey : @(YES)
                          };
    [MKMapItem openMapsWithItems:items launchOptions:dic];

第二种:调起百度地图进行导航:

可以参考:百度地图官方文档 实现如下:

//百度地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name:%@&mode=driving&coord_type=bd09ll",modelData.coordinate.latitude,modelData.coordinate.longitude, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]];
    }

参数设置可以参考文档

第三种:调起高德地图进行导航:

可以参考:高德地图官方文档 实现如下:

CLLocationCoordinate2D gcj02Coord = [JZLocationConverter bd09ToGcj02:modelData.coordinate];

    float shopLat = gcj02Coord.latitude;
    float shoplng = gcj02Coord.longitude;
    
    //高德地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        NSMutableDictionary *gaodeMapDic = [NSMutableDictionary dictionary];
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&backScheme=%@&sname=我的位置&dev=1&t=0&dlat=%f&dlon=%f&dname=%@&dev=0",@"AppName",@"url schemes",shopLat,shoplng, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]];  
    }

第四种:调起腾讯地图进行导航:

可以参考:腾讯地图官方文档 实现如下:

//腾讯地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"qqmap://"]]) {
        NSMutableDictionary *qqMapDic = [NSMutableDictionary dictionary];
        NSString *urlString = [[NSString stringWithFormat:@"qqmap://map/routeplan?from=我的位置&type=drive&tocoord=%f,%f&to=%@",shopLat,shoplng, modelData.titleName] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
       [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString: urlString]]; 
    }
