iOS 开发笔记

导航到地图，已经不是什么新鲜事了。网上有好多参考的资料，我总结出只需要两步

第一步：在info中加上支持的各平台

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

    <key>LSApplicationQueriesSchemes</key>
    <array>
        <string>iosamap</string>
        <string>comgooglemaps</string>
        <string>baidumap</string>
        <string>qqmap</string>
    </array>

第二步：直接在使用的地方，调用下面的代码即可

- (void)mapChooose {
    //系统版本高于8.0，使用UIAlertController
    UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"导航到设备" message:nil preferredStyle:UIAlertControllerStyleActionSheet];
    //自带地图
    [alertController addAction:[UIAlertAction actionWithTitle:@"自带地图" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        NSLog(@"alertController -- 自带地图");
        //使用自带地图导航
        MKMapItem *currentLocation =[MKMapItem mapItemForCurrentLocation];
        MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:self.coordinate addressDictionary:nil]];
        [MKMapItem openMapsWithItems:@[currentLocation,toLocation] launchOptions:@{MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving, MKLaunchOptionsShowsTrafficKey:[NSNumber numberWithBool:YES]}];
    }]];
    
    //判断是否安装了高德地图，如果安装了高德地图，则使用高德地图导航
    if ( [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"iosamap://"]]) {
        [alertController addAction:[UIAlertAction actionWithTitle:@"高德地图" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSLog(@"alertController -- 高德地图");
            NSString *urlsting =[[NSString stringWithFormat:@"iosamap://navi?sourceApplication= &backScheme= &lat=%f&lon=%f&dev=0&style=2",self.coordinate.latitude,self.coordinate.longitude]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            [[UIApplication  sharedApplication]openURL:[NSURL URLWithString:urlsting]];
        }]];
    }
    
    //判断是否安装了百度地图，如果安装了百度地图，则使用百度地图导航
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"baidumap://"]]) {
        [alertController addAction:[UIAlertAction actionWithTitle:@"百度地图" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSLog(@"alertController -- 百度地图");
            NSString *urlsting =[[NSString stringWithFormat:@"baidumap://map/direction?origin={{我的位置}}&destination=latlng:%f,%f|name=目的地&mode=driving&coord_type=gcj02",self.coordinate.latitude,self.coordinate.longitude] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlsting]];
        }]];
    }
    
    //判断是否安装了谷歌地图，如果安装了谷歌地图，则使用谷歌地图导航
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"comgooglemaps://"]]) {
        [alertController addAction:[UIAlertAction actionWithTitle:@"谷歌地图"style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            NSString *urlString = [[NSString stringWithFormat:@"comgooglemaps://?x-source=%@&x-success=%@&saddr=&daddr=%f,%f&directionsmode=driving",
                                    @"",//appName,
                                    @"",//urlScheme,
                                    self.coordinate.latitude,
                                    self.coordinate.longitude]
                                   stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];
        }]];
    }
    
    //添加取消选项
    [alertController addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
        [alertController dismissViewControllerAnimated:YES completion:nil];
    }]];
    
    //显示alertController
    [self presentViewController:alertController animated:YES completion:nil];
}
