开发者可在百度地图iOS SDK的下载页面下载到最新版的地图SDK，下载地址为：http://developer.baidu.com/map/index.php?title=iossdk/sdkiosdev-download

1.申请密钥

百度地图iOS SDK开发密钥的申请地址为：http://lbsyun.baidu.com/apiconsole/key

2.配置开发环境

2.1、根据需要导入 .framework包

百度地图 iOS SDK 采用分包的形式提供 .framework包，请广大开发者使用时确保各分包的版本保持一致。其中BaiduMapAPI_Base.framework为基础包，使用SDK任何功能都需导入，其他分包可按需导入。
将所需的BaiduMapAPI_.framework拷贝到工程所在文件夹下。
在 TARGETS->Build Phases-> Link Binary With Libaries中点击“+”按钮，在弹出的窗口中点击“Add Other”按钮，选择BaiduMapAPI_.framework添加到工程中。
注: 静态库中采用Objective-C++实现，因此需要您保证您工程中至少有一个**.mm**后缀的源文件(您可以将任意一个.m后缀的文件改名为.mm)，或者在工程属性中指定编译方式，即在Xcode的Project -> Edit Active Target -> Build Setting 中找到 Compile Sources As，并将其设置为**"Objective-C++"**

2.2、引入所需的系统库

百度地图SDK中提供了定位功能和动画效果，v2.0.0版本开始使用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以前为 libsqlite3.0.dylib）
CoreTelephony.framework
libstdc++.6.0.9.tbd（xcode7以前为libstdc++.6.0.9.dylib）。
（注：加粗标识的系统库为v2.9.0新增的系统库，使用v2.9.0及以上版本的地图SDK，务必增加导入这3个系统库。）
添加方式：在Xcode的Project -> Active Target ->Build Phases ->Link Binary With Libraries，添加这几个系统库即可。

2.3、引入mapapi.bundle资源文件

如果使用了基础地图功能，需要添加该资源，否则地图不能正常显示mapapi.bundle中存储了定位、默认大头针标注View及路线关键点的资源图片，还存储了矢量地图绘制必需的资源文件。如果您不需要使用内置的图片显示功能，则可以删除bundle文件中的image文件夹。您也可以根据具体需求任意替换或删除该bundle中image文件夹的图片文件。方法：选中工程名，在右键菜单中选择Add Files to “工程名”…，从BaiduMapAPI_Map.framework||Resources文件中选择mapapi.bundle文件，并勾选“Copy items if needed”复选框，单击“Add”按钮，将资源文件添加到工程中。

2.4、环境配置

1）如果您只在Xib文件中使用了BMKMapView，没有在代码中使用BMKMapView，编译器在链接时不会链接对应符号，需要在工程属性中显式设定：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，为了能够在iOS9中正常使用地图SDK，请在"Info.plist"中进行如下配置，否则影响SDK的使用。

NSAppTransportSecurity NSAllowsArbitraryLoads ```

3）如果在iOS9中使用了调起百度地图客户端功能，必须在"Info.plist"中进行如下配置，否则不能调起百度地图客户端。

LSApplicationQueriesSchemes baidumap```

2.5、引入头文件

在使用SDK的类按需引入下边的头文件：

#import //引入base相关所有的头文件
#import //引入地图功能所有的头文件
#import //引入检索功能所有的头文件
#import //引入云检索功能所有的头文件
#import //引入定位功能所有的头文件
#import //引入计算工具所有的头文件
#import //引入周边雷达功能所有的头文件
#import < BaiduMapAPI_Map/BMKMapView.h>//只引入所需的单个头文件```

#3、相关代码
#3.1管理地图的生命周期
自2.0.0起，BMKMapView新增viewWillAppear、viewWillDisappear方法来控制BMKMapView的生命周期，并且在一个时刻只能有一个BMKMapView接受回调消息，因此在使用BMKMapView的viewController中需要在viewWillAppear、viewWillDisappear方法中调用BMKMapView的对应的方法，并处理delegate，代码如下：

-(void)viewWillAppear:(BOOL)animated {
[_mapView viewWillAppear];
_mapView.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
}

-(void)viewWillDisappear:(BOOL)animated {
[_mapView viewWillDisappear];
_mapView.delegate = nil; // 不用时，置nil
}```

3.2 使用百度地图，启动BaiduMapManager

2）在AppDelegate里操作：

@interface AppDelegate : NSObject { BMKMapManager* _mapManager;}```

@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 1.创建窗口
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
// 2.设置窗口的根控制器
[self.window switchRootViewController];
// 3.显示窗口
[self.window makeKeyAndVisible];
float version = [[[UIDevice currentDevice] systemVersion] floatValue];
if (version >= 8.0) {
// iOS8+ IconBadge需授权
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
// 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:BaiduMapAppKey generalDelegate:self];
if (!ret) {
NSLog(@"manager start failed!");
}
return YES;
}```

4、定位功能及反地理编码出地理位置

1）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```

![](http://upload-images.jianshu.io/upload_images/2023270-e1e5ae4e6eebe331.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240)
2）部分代码如下：

@interface QTXHomeController (){
BMKLocationService *_locService;
BMKGeoCodeSearch *_geoCodeSearch;
}```

- (void)viewDidLoad { 
[super viewDidLoad]; // 设置地图定位
 [self setupBMKLocation];
}
#pragma mark - BMKLocationService- (void)setupBMKLocation { 
//初始化
BMKLocationService _locService = [[BMKLocationService alloc]init]; 
  _locService.delegate = self; // 初始化编码服务

  _geoCodeSearch.delegate = self; //启动
  LocationService [_locService startUserLocationService];
}
-(void)viewWillAppear:(BOOL)animated { 
  [super viewWillAppear:animated];
   _locService.delegate = self;
}
-(void)viewWillDisappear:(BOOL)animated { 
  [super viewWillDisappear:animated]; 
  _locService.delegate = nil;
