iOS讲解迷惑之集成百度地图

cmd&＃43;shift&＃43;N 创建一个 singel视图, 进行各种配置, 把任意一个.m文件的后缀名改为.mm

1. 在appdelegate中

#import "AppDelegate.h"
#import //引入所有的头文件
&＃64;interface AppDelegate ()&＃64;property (nonatomic, strong) UINavigationController *navC;
&＃64;property (nonatomic, strong) BMKMapManager *mapManager;&＃64;end&＃64;implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {// Override point for customization after application launch._mapManager &＃61; [[BMKMapManager alloc]init];// 如果要关注网络及授权验证事件&＃xff0c;请设定 generalDelegate参数BOOL ret &＃61; [_mapManager start:&＃64;"j9UnN8OK0S5EkjY3MPvFxpqc" generalDelegate:nil];if (!ret) {NSLog(&＃64;"manager start failed!");}// Add the navigation controller&＃39;s view to the window and display.[self.window addSubview:_navC.view];return YES;
}


2. 在viewController 

#import "ViewController.h"
#import //引入所有的头文件
#import "UIView&＃43;WLFrame.h"
#define kMargin 20
#define kSmallMargin 10// 遵守协议
/**BMKMapViewDelegate 地图协议BMKLocationServiceDelegate 定位服务协议BMKGeoCodeSearchDelegate 地理编码搜索协议BMKRouteSearchDelegate 路线搜索协议*/
