如何在skobbler導航中啓用標題下一回合視圖

Question

在演示版本中，我注意到帶有箭頭的標題，指向下一個回合，以及距離和用戶需要轉向的下一條街道的名稱。

這裏是截圖：

我無法從文檔也不演示應用程序如何啓用它搞清楚。 Anny的建議？

Answer 1

首先，必須實施SKNavigationDelegate和SKRoutingDelegate。

不要忘記設置代表：

[SKRoutingService sharedInstance].routingDelegate = self; 
[SKRoutingService sharedInstance].navigationDelegate = self; 

和代碼非常重要的一塊：

SKAdvisorSettings* advisorSettings = [[SKAdvisorSettings alloc]init]; 
[SKRoutingService sharedInstance].advisorConfigurationSettings = advisorSettings; 
[Constants shared].route.requestAdvices=YES; 

然後，計算出的路線後，您就可以與這些玩方法：

-(void)routingService:(SKRoutingService *)routingService didChangeNextStreetName:(NSString *)nextStreetName streetType:(SKStreetType)streetType countryCode:(NSString *)countryCode 
{ 
// This method returns the Name of the next street 
_txtNextStreetName.text = [NSString stringWithFormat:@"%@",nextStreetName]; 
} 

// This method returns visual guidance to the next turn on the road 
-(void)routingService:(SKRoutingService *)routingService didChangeCurrentAdviceImage:(UIImage *)adviceImage withLastAdvice:(BOOL)isLastAdvice 
{ 
[_imgVisualAdvice setImage:adviceImage]; 
} 

//和距離

-(void)routingService:(SKRoutingService *)routingService didChangeSecondaryVisualAdviceDistance:(int)distance withFormattedDistance:(NSString *)formattedDistance 
{ 

    _txtNextStreetDistance.text = [NSString StringWithFormat:@"%@",formattedDistance]; 

}
