集成百度地图，实现基本定位，检索，自定义大头针。
1.集成百度地图，当然前提还是去注册百度地图开发者
2.接下来创建应用
创建应用.png
3.百度地图AK
百度地图AK.png
4.cocoaPods导入百度SDK
platform :ios, '6.0'
pod 'BaiduMapKit'
5.项目plist配置
plist配置.png
接下来正事开始!
6.在AppDelegate.m中导入头文件:
#import <BaiduMapAPI_Base/BMKMapManager.h>
在didFinishLaunchingWithOptions方法中:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//创建并初始化一个引擎对象
BMKMapManager *manager = [[BMKMapManager alloc] init];
//启动地图引擎
BOOL success = [manager start:@"百度地图AK" generalDelegate:nil];
if (!success) {
NSLog(@"失败");
}
return YES;
}
7.在viewController.m 中导入头文件,根据需要导入
#import "ViewController.h"
#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件
#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件
#import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入检索功能所有的头文件
#import <BaiduMapAPI_Cloud/BMKCloudSearchComponent.h>//引入云检索功能所有的头文件
#import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件
#import <BaiduMapAPI_Utils/BMKUtilsComponent.h>//引入计算工具所有的头文件
#import <BaiduMapAPI_Radar/BMKRadarComponent.h>//引入周边雷达功能所有的头文件
#import "MZLPopImage.h"
//声明BMKMapView
@interface ViewController ()<BMKMapViewDelegate,BMKLocationServiceDelegate,BMKPoiSearchDelegate>

终于完了，够详细了吧。自己写的，看看就好。
【Update】
点击大头针切换图片MZLPopImage类
在MZLPopImage.h中
@interface MZLPopImage : NSObject
+ (UIImage*)getUIImageByValue:(NSInteger)nValue andIsSelect:(BOOL)bSelect;
@end
在MZLPopImage.m中
#define IMAGEOF(x) ([UIImage imageNamed:x])
@implementation MZLPopImage
+(UIImage*)convertViewToImage:(UIView*)view
{
CGSize s = view.bounds.size;
//第一个参数表示区域大小。第二个参数表示是否是非透明的。如果需要显示半透明效果，需要传NO，否则传YES。第三个参数就是屏幕密度了
UIGraphicsBeginImageContextWithOptions(s, NO, [UIScreen mainScreen].scale);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage*image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
//图片选中，可设置nVlaue图片上文字
+ (UIImage*)getUIImageByValue:(NSInteger)nValue andIsSelect:(BOOL)bSelect
{
UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 17, 25)];
imageView.image = bSelect ? IMAGEOF(@"icon_btn_red") : IMAGEOF(@"icon_btn_black");
UILabel *lb = [[UILabel alloc]initWithFrame:CGRectMake(5, 0, 40, 28)];
lb.text = [NSString stringWithFormat:@"%ld",(long)nValue];
lb.font = [UIFont boldSystemFontOfSize:18.f];
lb.adjustsFontSizeToFitWidth = YES;
lb.textAlignment = NSTextAlignmentCenter;
lb.textColor = [UIColor whiteColor];
[imageView addSubview:lb];
return [MZLPopImage convertViewToImage:imageView];
}
以上是全部代码，如果实现有问题请在下面回复。
最后附上官方文档。
