正好做到百度地图的poi检索，拿来分享一下，基于百度地图2.3.0SDK开发，说实话，这个新版本poi真不好用
先来看头文件里面，定义poi对象，当然你也可以写到实现文件里面
#import <UIKit/UIKit.h>
#import "BMapKit.h"
@interface NearByPlaceViewController : ViewControllerBase <BMKPoiSearchDelegate>
{
BMKPoiSearch *_poiSearch; //poi搜索
}
@end
#import "NearByPlaceViewController.h"
#import "UserLocationManager.h"
#import "iToast.h"
@interface NearByPlaceViewController ()
{
NSString *_cityName; // 检索城市名
NSString *_keyWord; // 检索关键字
int currentPage; // 当前页
}
@property (retain,nonatomic) NSMutableArray *poiResultArray; //poi结果信息集合
@end
@implementation NearByPlaceViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];
[self setArraySpace];
[self initPoiSearch];
}
#pragma mark --对数组开空间
-(void)setArraySpace
{
NSMutableArray *mutArr1 = [[NSMutableArray alloc]init];
_poiResultArray = mutArr1;
NSMutableArray *mutArr2 = [[NSMutableArray alloc]init];
_searchHistoryArray = mutArr2;
}
#pragma mark --初始化poi类
-(void)initPoiSearch
{
_poiSearch = [[BMKPoiSearch alloc]init];
_poiSearch.delegate = self;
currentPage = 0;
//附近云检索，其他检索方式见详细api
BMKNearbySearchOption *nearBySearchOption = [[BMKNearbySearchOption alloc]init];
nearBySearchOption.pageIndex = currentPage; //第几页
nearBySearchOption.pageCapacity = 10; //最多几页
nearBySearchOption.keyword = @"设施"; //检索关键字
nearBySearchOption.location = [UserLocationManager sharedInstance].clloction.coordinate; // poi检索点
nearBySearchOption.radius = 1000; //检索范围 m
BOOL flag = [_poiSearch poiSearchNearBy:nearBySearchOption];
if(flag)
{
NSLog(@"城市内检索发送成功");
}
else
{
NSLog(@"城市内检索发送失败");
}
}
#pragma mark --BMKPoiSearchDelegate
/**
*返回POI搜索结果
*@param searcher 搜索对象
*@param poiResult 搜索结果列表
*@param errorCode 错误号，@see BMKSearchErrorCode
*/
- (void)onGetPoiResult:(BMKPoiSearch*)searcher result:(BMKPoiResult*)poiResult errorCode:(BMKSearchErrorCode)errorCode
{
if (errorCode == BMK_SEARCH_NO_ERROR)
{
for (int i = 0; i < poiResult.poiInfoList.count; i++)
{
BMKPoiInfo* poi = [poiResult.poiInfoList objectAtIndex:i];
[_poiResultArray addObject:poi];
}
}
else if (errorCode == BMK_SEARCH_RESULT_NOT_FOUND)
{
[self setToast:iToastGravityBottom withText:@"抱歉,查不到你附近范围内的信息!"];
}
}
#pragma mark - toast
-(void)setToast:(iToastGravity) gravity withText:(NSString*) text
{
iToast *toast = [iToast makeText:text];
[toast setGravity:gravity];
[toast setDuration:5];
[toast setFontSize:15];
[toast show];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

大家有什么不明白的可以给我留言，必回，彼此交流一下，后续我会把做到的百度地图遇到的问题详细记录，大家可以多交流一下！
