释放双眼,带上耳机,听听看~!
要跳转第三方App实现导航就首先需要了解两个问题 1.怎么判断手机上是否安装了第三方导航App 2.怎么实现跳转到第三方App
问题1 比如你如果要检测是否有安装百度地图APP,那么就是:
[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]];
常用的4个地图的 URL Scheme: 1.苹果自带地图(不需要检测,所以不需要URL Scheme) 2.百度地图 :baidumap:// 3.高德地图 :iosamap:// 4.谷歌地图 :comgooglemaps://
问题2 在 iOS 9 之后我们做跳转是需要有个白名单的

具体实现代码
#import <MapKit/MapKit.h> @implementation ThirdAppNavigationManager + (void)thirdAppNavigation:(NSString *)lat lng:(NSString *)lng { 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",lat,lng] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]; 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",lat,lng] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]; 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",lat,lng] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]; 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",lat,lng] stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]; 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 navAppleMap:lat lng:lng]; }]; [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] options:@{} completionHandler:^(BOOL success) { }]; }]; [alert addAction:action]; } UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) { NSLog(@"点击了取消"); }]; [alert addAction:cancelAction]; [[UIViewController getCurrentViewController] presentViewController:alert animated:YES completion:nil]; } //苹果地图 + (void)navAppleMap:(NSString *)lat lng:(NSString *)lng { //终点坐标 CLLocationCoordinate2D loc = CLLocationCoordinate2DMake(lat.doubleValue, lng.doubleValue); //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]; NSDictionary *dic = @{ MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving, MKLaunchOptionsMapTypeKey : @(MKMapTypeStandard), MKLaunchOptionsShowsTrafficKey : @(YES) }; [MKMapItem openMapsWithItems:items launchOptions:dic]; } @end
