開發者可在百度地圖iOS SDK的下載頁面下載到最新版的地圖SDK，下載地址為：http://developer.baidu.com/map/index.php?title=iossdk/sdkiosdev-download
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
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;
}
