我的代码如下：

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    [RMMapView class]; 
    TokenManager* tokenManager = [[TokenManager alloc] initWithApikey:@"a53b3323702f42fc8486e24df34f9ac3"]; 
    _routingManager = [[CMRoutingManager alloc] initWithMapView:mapView tokenManager:tokenManager]; 
    _routingManager.delegate = self; 
    CLLocationCoordinate2D from; 
    from.latitude= 53.358311; 
    from.longitude=-6.481934; 
    CLLocationCoordinate2D to; 
    to.latitude=52.657616; 
    to.longitude=-8.635254; 
    CMRoutingVehicle transport = CMVehicleCar;//CMVehicleWalking or CMVehicleBike 
    [_routingManager findRouteFrom:from to:to onVehicle:transport]; 
}

任何帮助将不胜感激:)

此异常

2011-06-23 17:07:56.154 TopStation[1307:9b03] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSArray arrayWithContentsOfURL:headers:]: unrecognized selector sent to class 0x2bdb4c4'

说，你正在发送消息给一个类，它没有方法，适合它。 +[NSArray arrayWithContentsOfURL:headers:]

我的猜测：你是不是进口的NSArray上一个类别，声明和实现+arrayWithContentsOfURL:headers:

并确保您添加的链接标志-ObjC -all_load

我不能添加'-ObjC'和' -all_load' 标志，因为我使用JSON，并在编译时产生错误。 – Malloc

比你应该调查。 – vikingosegundo
