1.申請密鑰

百度地圖iOS SDK開發密鑰的申請地址為：
http://lbsyun.baidu.com/apiconsole/key

2.配置開發環境

2.1、根據需要導入 .framework包

百度地圖 iOS SDK 采用分包的形式提供 .framework包，請廣大開發者使用時確保各分包的版本保持一致。其中BaiduMapAPI_Base.framework為基礎包，使用SDK任何功能都需導入，其他分包可按需導入。
將所需的BaiduMapAPI_.framework拷貝到工程所在文件夾下。
在 TARGETS->Build Phases-> Link Binary With Libaries中點擊“+”按鈕，在彈出的窗口中點擊“Add Other”按鈕，選擇BaiduMapAPI_.framework添加到工程中。
注: 靜態庫中采用Objective-C++實現，因此需要您保證您工程中至少有一個**.mm**后綴的源文件(您可以將任意一個.m后綴的文件改名為.mm)，或者在工程屬性中指定編譯方式，即在Xcode的Project -> Edit Active Target -> Build Setting 中找到 Compile Sources As，并將其設置為**"Objective-C++"**

2.2、引入所需的系統庫

百度地圖SDK中提供了定位功能和動畫效果，v2.0.0版本開始使用OpenGL渲染，因此您需要在您的Xcode工程中引入CoreLocation.framework和QuartzCore.framework、OpenGLES.framework、SystemConfiguration.framework、CoreGraphics.framework、Security.framework、libsqlite3.0.tbd（xcode7以前為 libsqlite3.0.dylib）、CoreTelephony.framework 、libstdc++.6.0.9.tbd（xcode7以前為libstdc++.6.0.9.dylib）。
（注：加粗標識的系統庫為v2.9.0新增的系統庫，使用v2.9.0及以上版本的地圖SDK，務必增加導入這3個系統庫。）
添加方式：在Xcode的Project -> Active Target ->Build Phases ->Link Binary With Libraries，添加這幾個系統庫即可。

2.3、引入mapapi.bundle資源文件

如果使用了基礎地圖功能，需要添加該資源，否則地圖不能正常顯示mapapi.bundle中存儲了定位、默認大頭針標注View及路線關鍵點的資源圖片，還存儲了矢量地圖繪制必需的資源文件。如果您不需要使用內置的圖片顯示功能，則可以刪除bundle文件中的image文件夾。您也可以根據具體需求任意替換或刪除該bundle中image文件夾的圖片文件。
方法：選中工程名，在右鍵菜單中選擇Add Files to “工程名”…，從BaiduMapAPI_Map.framework||Resources文件中選擇mapapi.bundle文件，并勾選“Copy items if needed”復選框，單擊“Add”按鈕，將資源文件添加到工程中。

2.4、環境配置

1）如果您只在Xib文件中使用了BMKMapView，沒有在代碼中使用BMKMapView，編譯器在鏈接時不會鏈接對應符號，需要在工程屬性中顯式設定：在Xcode的Project -> Edit Active Target -> Build Setting -> Other Linker Flags中添加-ObjC

2）由于iOS9改用更安全的https，為了能夠在iOS9中正常使用地圖SDK，請在"Info.plist"中進行如下配置，否則影響SDK的使用。

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

3）如果在iOS9中使用了調起百度地圖客戶端功能，必須在"Info.plist"中進行如下配置，否則不能調起百度地圖客戶端。

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>baidumap</string>
</array>

2.5、引入頭文件

在使用SDK的類 按需 引入下邊的頭文件：
#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相關所有的頭文件
 
#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地圖功能所有的頭文件
 
#import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入檢索功能所有的頭文件
 
#import <BaiduMapAPI_Cloud/BMKCloudSearchComponent.h>//引入云檢索功能所有的頭文件
 
#import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的頭文件
 
#import <BaiduMapAPI_Utils/BMKUtilsComponent.h>//引入計算工具所有的頭文件
 
#import <BaiduMapAPI_Radar/BMKRadarComponent.h>//引入周邊雷達功能所有的頭文件
 
#import < BaiduMapAPI_Map/BMKMapView.h>//只引入所需的單個頭文件

3、相關代碼

3.1管理地圖的生命周期

自2.0.0起，BMKMapView新增viewWillAppear、viewWillDisappear方法來控制BMKMapView的生命周期，并且在一個時刻只能有一個BMKMapView接受回調消息，因此在使用BMKMapView的viewController中需要在viewWillAppear、viewWillDisappear方法中調用BMKMapView的對應的方法，并處理delegate，代碼如下：

-(void)viewWillAppear:(BOOL)animated      
{      
    [_mapView viewWillAppear];      
    _mapView.delegate = self; // 此處記得不用的時候需要置nil，否則影響內存的釋放      
}      
-(void)viewWillDisappear:(BOOL)animated      
{      
        [_mapView viewWillDisappear];      
      _mapView.delegate = nil; // 不用時，置nil      
}

3.2 使用百度地圖，啟動BaiduMapManager

2）在AppDelegate里操作：

@interface AppDelegate : NSObject <UIApplicationDelegate, BMKGeneralDelegate>
{
    BMKMapManager* _mapManager;
}

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // 1.創建窗口
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    // 2.設置窗口的根控制器
    [self.window switchRootViewController];
    // 3.顯示窗口
    [self.window makeKeyAndVisible];
    
    float version = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (version >= 8.0) { // iOS8+ IconBadge需授權
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    }
    
    // 要使用百度地圖，請先啟動BaiduMapManager
    _mapManager = [[BMKMapManager alloc]init];
    // 如果要關注網絡及授權驗證事件，請設定generalDelegate參數
    BOOL ret = [_mapManager start:BaiduMapAppKey generalDelegate:self];
    if (!ret) {
        NSLog(@"manager start failed!");
    }

    return YES;
}

4、定位功能及反地理編碼出地理位置

1）自iOS SDK v2.5.0起，為了對iOS8的定位能力做兼容，做了相應的修改，開發者在使用過程中注意事項如下：

 需要在info.plist里添加（以下二選一，兩個都添加默認使用NSLocationWhenInUseUsageDescription）：
NSLocationWhenInUseUsageDescription ，允許在前臺使用時獲取GPS的描述
NSLocationAlwaysUsageDescription ，允許永久使用GPS的描述

2）部分代碼如下：

@interface QTXHomeController ()<BMKLocationServiceDelegate, BMKGeoCodeSearchDelegate>
{
    BMKLocationService *_locService;
    BMKGeoCodeSearch *_geoCodeSearch;
    
}

- (void)viewDidLoad {
    [super viewDidLoad];

    // 設置地圖定位
    [self setupBMKLocation];
}

#pragma mark - BMKLocationService

- (void)setupBMKLocation {
    
    //初始化BMKLocationService
    _locService = [[BMKLocationService alloc]init];
    _locService.delegate = self;
    
    // 初始化編碼服務
    _geoCodeSearch = [[BMKGeoCodeSearch alloc] init];
    _geoCodeSearch.delegate = self;
    
    //啟動LocationService
    [_locService startUserLocationService];
}

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    _locService.delegate = self;
}

-(void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    _locService.delegate = nil;
}

    _routesearch.delegate = self; // 此處記得不用的時候需要置nil，否則影響內存的釋放

    // 開始定位

    _mapView.showsUserLocation = NO;
}

- (void)dealloc {
    if (_routesearch != nil) {
        _routesearch = nil;
    }
    if (_mapView) {
        _mapView = nil;
    }
}

- (void)mapLocationClick {
    
    // 創建一張百度地圖
    // 1.首先接受基本的地圖功能
    _mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0, UI_View_Width, UI_View_Height)];
    _mapView.delegate = self;
    [self.view addSubview:_mapView];
    
    // 2.開始定位
