本文介绍了一段iOS代码示例，展示了如何根据是否安装了百度地图或高德地图应用来实现导航功能的跳转。若应用已安装，则直接打开对应的地图应用并设置起点与终点坐标；若未安装，则跳转至网页版地图服务。

+ (void)jumpToMapWithStartLat:(double)startLat startLong:(double)startLong endLat:(double)endLat endLong:(double)endLong {
    BOOL hasBaiduMap = NO;
    BOOL hasGaodeMap = NO;

    //是否安装百度地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://map/"]]){
        hasBaiduMap = YES;
    }

    //是否安装高德地图
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]){
        hasGaodeMap = YES;
    }

    if (hasBaiduMap)
    {
        //跳到百度地图客户端
        NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin=latlng:%f,%f|name:我的位置&destination=latlng:%f,%f|name:终点&mode=driving",startLat, startLong, endLat, endLong] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    }
    else if (hasGaodeMap)
    {
        //跳到高德地图客户端
        NSString *urlString = [[NSString stringWithFormat:@"iosamap://path?sourceApplication=%@&backScheme=%@&sid=BGVIS1&slat=%f&slon=%f&sname=%@&did=BGVIS2&dlat=%f&dlon=%f&dname=%@&dev=0&m=0&t=0",@"小美到家", @"xmdp5bCP576O5bqX6ZO6", startLat, startLong, @"起点", endLat, endLong, @"终点"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    } else {
        NSString *urlString = [[NSString stringWithFormat:@"http://map.baidu.com?destination=latlng:%f,%f|name:终点&mode=driving",endLat, endLong] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

    }

}
