首先按照百度配置要求配置开发环境

1:在AppDelegate.mm中设置百度定位的key

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [self configureBaiduLocation];
    return YES;
}
-(void)configureBaiduLocation
{
    _mapManager = [[BMKMapManager alloc]init];
    BOOL ret = [_mapManager start:@"bP9bEpZ5WjmIUo10dQQGKo0EXcXxtvnh" generalDelegate:self];
    if (!ret) {
        NSLog(@"manager start failed!");
    }
}
- (void)onGetNetworkState:(int)iError
{
    if (0 == iError) {
        NSLog(@"联网成功");
    }
    else{
        NSLog(@"onGetNetworkState %d",iError);
    }
    
}

- (void)onGetPermissionState:(int)iError
{
    if (0 == iError) {
        NSLog(@"授权成功");
    }
    else {
        NSLog(@"onGetPermissionState %d",iError);
    }
}
