iOS调用第三方地图App进行导航方法

前言

• App内根据手机上装载的地图App将其显示在弹出的选择框，选择对应地图跳转进入地图导航。需要用到- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);方法判断手机是否已安装相应地图App。
• 要进行跳转需要先在xcode的plist文件内将目标App的url Scheme加入白名单(LSApplicationQueriesSchemes)。

常见第三方地图App的url Scheme

• 百度地图：baidumap
• 高德地图：iosamap
• 谷歌地图：comgooglemaps
• 腾讯地图：qqmap

plist文件新增LSApplicationQueriesSchemes关键字，类型为NSArray，并在其下添加子目录，类型为NSString，内容为各地图对应的url Scheme。

白名单LSApplicationQueriesSchemes:

　　　　　　　　　　

代码示例

//导航只需要目的地经纬度，endLocation为纬度、经度的数组
-(void)doNavigationWithEndLocation:(NSArray *)endLocation
{

    //NSArray * endLocation = [NSArray arrayWithObjects:@"26.08",@"119.28", nil];

    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[@"url"] = urlString;
        [maps addObject:baiduMapDic];

    }

    //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 navAppleMap];
