iOS经过URL调用第三方地图进行导航

    在app中有许多场景须要用到导航,好比 我给你发了一个地理位置,你能够打开这个位置而后经过位置导航找到我.

    导航能够经过内嵌三方SDK实现也能够经过跳转三方app实现,后者相对前者来讲相对简单并且也能有效的减少app体积.下面就为你们介绍下后者实现.

    

// 代码以下 这里只添加了三种地图 (苹果官方地图,高德,百度),若有其它须要能够本身添加,若是没有安装高德或者百度地图 sheet的titles里面是不会显示的

UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"选择地图" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:nil, nil];
 
    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"http://maps.apple.com/"]])
    {
        [sheet addButtonWithTitle:@"苹果地图"];
    }
    
    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]])
    {
        [sheet addButtonWithTitle:@"百度地图"];
    }

    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]])
    {
        [sheet addButtonWithTitle:@"高德地图"];
    }

    [sheet showInView:self.view];

下面实现actionSheet的代理方法

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    NSString *title = [actionSheet buttonTitleAtIndex:buttonIndex];
    
    if ([title isEqualToString:@"苹果地图"]) {
            MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
        MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:_currentLocationCoordinate addressDictionary:nil]];
        // 目的地名字
        toLocation.name = self.addressString;
        
            [MKMapItem openMapsWithItems:@[currentLocation, toLocation]
                           launchOptions:@{MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];

    } else if ([title isEqualToString:@"高德地图"]) {
            NSString *urlString = [[NSString stringWithFormat:@"iosamap://navi?sourceApplication=%@&backScheme=%@&lat=%f&lon=%f&dev=0&style=2",self.appName,self.urlScheme,
                                    _toLocationCoordinate.latitude,
                                    _toLocationCoordinate.longitude]
                                   stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

    } else if ([title isEqualToString:@"百度地图"]) {
            NSString *urlString = [[NSString stringWithFormat:@"baidumap://map/direction?origin=%f,%f&destination=latlng:%f,%f|name:%@&mode=driving&src=dangdang://&coord_type=gcj02",
                                    _myLocation.latitude,_myLocation.longitude,
                                    _toLocationCoordinate.latitude,
                                    _toLocationCoordinate.longitude,
                                    self.addressString] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            NSLog(@"%@",urlString);

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
    }
}

 

// 通用参数
self.appName = app名称  self.urlScheme = appUrlScheme _toLocationCoordinate = 目的地经纬度

// 只有调用百度地图才须要当前的经纬度
_myLocation = 当前经纬度 

 具体 这些URL以及参数的设置均可以在官方文档查看
 须要注意的是 iOS9.0以上的系统须要在info.plist文件设置白名单才能调起三方地图

 白名单设置

设置URLScheme

info->URLTypes 添加urlScheme

如此即可以轻松的在app中调用三方地图进行导航了!
