百度地图集成 ，划线定位 ，修改地图图标时时划线 ，源码分享 话不多说直接源码。
注意：导入 sdk,如有方法报错 注意inforplist 和 viewcontroller.mm
1.AppDelegate 添加头文件 定义属性
@interface AppDelegate (){
BMKMapManager* _mapManager;
}
2.didFinishLaunchingWithOptions 方法里添加
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
_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:@"imlNRyuFnypuLPFe7WCAjnSPSLjC2EE1" generalDelegate:nil];
if (!ret) {
NSLog(@"manager start failed!");
}
// Add the navigation controller's view to the window and display.
[self.window makeKeyAndVisible];
return YES;
}
viewController里添加
// ViewController.m
// baidumap
