iOS百度地图探索

新建工程后,几项准备:

1、工程中一个文件设为.mm后缀

2、在Xcode的Project -> Edit Active Target -> Build -> Linking -> Other Linker Flags中添加-ObjC

3、 设置静态库的链接路径，在Xcode的Project -> Edit Active Target -> Build -> Search Path -> Library Search Paths中添加您的静态库目录，比如"$(SRCROOT)/../libs/Release$(EFFECTIVE_PLATFORM_NAME)"，$(SRCROOT)宏代表您的工程文件目录，$(EFFECTIVE_PLATFORM_NAME)宏代表当前配置是OS还是simulator

4、framework: CoreLocation.framework和QuartzCore.framework、OpenGLES.framework、SystemConfiguration.framework、CoreGraphics.framework、Security.framework

5、自iOS SDK v2.5.0起，为了对iOS8的定位能力做兼容，做了相应的修改，开发者在使用过程中注意事项如下： 需要在info.plist里添加（以下二选一，两个都添加默认使用NSLocationWhenInUseUsageDescription）：

NSLocationWhenInUseUsageDescription ，允许在前台使用时获取GPS的描述

NSLocationAlwaysUsageDescription ，允许永久使用GPS的描述

首先要在appdelegate里面添加

BMKMapManager

- (BOOL)application:(UIApplication *)application   
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {       // 要使用百度地图，请先启动BaiduMapManager  
    _mapManager = [[BMKMapManager alloc]init];   
// 如果要关注网络及授权验证事件，请设定     generalDelegate参数  
    BOOL ret = [_mapManager start:@"在此处输入您的授权Key"  generalDelegate:nil];  
    if (!ret) {  
        NSLog(@"manager start failed!");  
    }  
// Add the navigation controller's view to the window and display.  
    [self.window addSubview:navigationController.view];  
    [self.window makeKeyAndVisible];  
   return YES;  
}

定位：

@interface ViewController ()<BMKMapViewDelegate,BMKCloudSearchDelegate,BMKLocationServiceDelegate>
{
    BMKMapView* mapView;
    BMKCloudSearch* search;
    BMKLocationService* location;
}

 

- (void)viewDidLoad {
    [super viewDidLoad];
    CGRect rect = CGRectMake(0, 0, 320, 400);
    mapView = [[BMKMapView alloc] initWithFrame:rect];
    [self.view addSubview:mapView];
    mapView.showsUserLocation= YES;
    //搜索
    search = [[BMKCloudSearch alloc] init];
    search.delegate = self;
    //服务
    location = [[BMKLocationService alloc] init];
    location.delegate = self;
    [location startUserLocationService];
    mapView.showsUserLocation = NO;
    mapView.userTrackingMode = BMKUserTrackingModeFollowWithHeading;
    mapView.showsUserLocation = YES;
    //搜索按钮
    UIButton* btSearch = [UIButton buttonWithType:UIButtonTypeCustom];
    [btSearch setTitle:@"搜索" forState:UIControlStateNormal];
    [btSearch addTarget:self action:@selector(clickSearch:) forControlEvents:UIControlEventTouchUpInside];
    [btSearch setFrame:CGRectMake(0, 400, 320, 80)];
    [btSearch setTintColor:[UIColor whiteColor]];
    [btSearch setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [self.view addSubview:btSearch];
}
-(void)viewWillAppear:(BOOL)animated{
    [mapView viewWillAppear];
    mapView.delegate = self;
}
-(void)viewWillDisappear:(BOOL)animated{
    [mapView viewWillDisappear];
    mapView.delegate = nil;
}

mapview代理实现:

- (void)didUpdateUserHeading:(BMKUserLocation *)userLocation
{
    [mapView updateLocationData:userLocation];
}
//处理位置坐标更新
- (void)didUpdateUserLocation:(BMKUserLocation *)userLocation
{
    [mapView updateLocationData:userLocation];
}

本地云检索：

 BMKCloudLocalSearchInfo *cloudLocalSearch = [[BMKCloudLocalSearchInfo alloc] init];
    cloudLocalSearch.ak = @"pjzXs0beL65WCNiRvtLrOe5X";
    cloudLocalSearch.geoTableId = 87197;
    cloudLocalSearch.pageIndex = 0;
    cloudLocalSearch.pageSize = 8;
    //
    cloudLocalSearch.region = @"成都市";
    cloudLocalSearch.keyword = @"ex";
    BOOL flag = [search localSearchWithSearchInfo:cloudLocalSearch];
    if (flag) {
        NSLog(@"本地云检索成功");
    }
    else{
        NSLog(@"本地云检索失败");
    }

检索回调：

- (void)onGetCloudPoiResult:(NSArray*)poiResultList searchType:(int)type errorCode:(int)error{
    // 清楚屏幕中所有的annotation
    NSArray* array = [NSArray arrayWithArray:mapView.annotations];
    [mapView removeAnnotations:array];
    if (error == BMKErrorOk) {
        BMKCloudPOIList* result = [poiResultList objectAtIndex:0];
        for (int i = 0; i < result.POIs.count; i++) {
            BMKCloudPOIInfo* poi = [result.POIs objectAtIndex:i];
            BMKPointAnnotation* item = [[BMKPointAnnotation alloc] init];
            CLLocationCoordinate2D pt = (CLLocationCoordinate2D){ poi.longitude,poi.latitude};
            item.coordinate = pt;
            item.title = poi.title;
            [mapView addAnnotation:item];
        }
    } else {
        NSLog(@"error ==%d",error);
    }
}

但到目前为止，使用xcode6.2beta，真机使用iphone5，始终在本地云检索的时候报错：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSCFConstantString stringByAppendingString:]: nil argument'

。求高人指教啊

终于找到原因所在，原来我的服务端的ak设置的sn校验，虽然我不知道什么是sn校验，但是最后改成了ip白名单。然后在“我的服务”中打开了服务，终于，奇迹出现了。终于回调成功了。。。呵呵呵。。。
