如何在Skobbler SDK for iOS中更改可视顾问颜色

Question

我正在尝试研究如何更改Skobbler SDK for iOS导航方面的视觉建议（箭头）颜色。我想在颜色方面定制视觉建议的各个方面......

我有以下内容：

    let configAdvice = SKVisualAdviceConfiguration.visualAdviceColor()
    configAdvice.countryCode = "US"
    configAdvice.streetType = SKStreetType.Secondary
    configAdvice.routeStreetColor = UIColor.blackColor()
    configAdvice.allowedStreetColor = UIColor.blackColor()
    configAdvice.forbiddenStreetColor = UIColor.blackColor()
    //        config.routeStreetColor = [UIColor colorWithHex:color alpha:1.0];
    //        config.allowedStreetColor = [UIColor colorWithHex:color alpha:0.0f];
    //        config.forbiddenStreetColor = [UIColor colorWithHex:color alpha:0.0f];

    SKRoutingService.sharedInstance().visualAdviceConfigurations = [configAdvice]

    let settings: SKAdvisorSettings = SKAdvisorSettings()
    let currentLanguage: String = "en_us"
    settings.advisorVoice = currentLanguage
    settings.advisorType = .AudioFiles
    SKRoutingService.sharedInstance().advisorConfigurationSettings = settings

结果是：

正如您所见，箭头是白色的，很难看到。所以我不确定为什么代码没有反映在视觉效果......

Answer 1

视觉指示：听didChangeFirstVisualAdvice。 在SKRouteState参数内，您将找到有关以下内容的信息：

• 当前（第一个）可视建议的路径：currentVisualAdvicePath（如果您想要彩色图像使用firstVisualAdviceImageWithColor）
• 下一个（第二个）可视建议的路径：secondaryVisualAdvicePath（如果你想要彩色图像使用secondVisualAdviceImageWithColor）

设置＆＃34;彩色建议的颜色方案＆＃34;使用以下visualAdviceConfigurations设置：

SKVisualAdviceConfiguration *visualAdviceColor1 = [SKVisualAdviceConfigurationvisualAdviceColor];
visualAdviceColor1.countryCode = @“DE";
visualAdviceColor1.streetType = SKStreetTypeSecondary;
visualAdviceColor1.routeStreetColor = [UIColor whiteColor];
visualAdviceColor1.allowedStreetColor = [UIColor grayColor];
visualAdviceColor1.forbiddenStreetColor = [UIColor blackColor];
[SKRoutingServicesharedInstance].visualAdviceConfigurations = @[visualAdviceColor1];

以下是演示应用程序（SDKTools项目）中使用的代码：

- (void)updateVisualAdviceSign {
    SKTNavigationVisualAdviceView *adviceView = self.mainView.navigationView.visualAdviceView;
    if (self.navigationInfo.firstAdvice) {
        if (self.navigationInfo.firstAdviceIsLast) {
            NSString *imageName = self.colorScheme[[SKTNavigationUtils destinationImageNameForStreetType:self.navigationInfo.nextStreetType]];
            imageName = [@"Icons/DestinationImages" stringByAppendingPathComponent:imageName];
            adviceView.signImageView.image = [UIImage navigationImageNamed:imageName];
        } else {
            SKVisualAdviceConfiguration *config = [self configurationForStreetType:self.navigationInfo.nextStreetType];
            adviceView.signImageView.image = [[SKRoutingService sharedInstance] visualAdviceImageForRouteAdvice:self.navigationInfo.firstAdvice color:config];
        }
    } else {
        adviceView.signImageView.image = nil;
    }
}

和

- (SKVisualAdviceConfiguration *)configurationForStreetType:(SKStreetType)streetType {
    NSString *name = [SKTNavigationUtils adviceSignColorNameForStreetType:streetType];
    uint32_t color = [self.colorScheme[name] unsignedIntValue];
    SKVisualAdviceConfiguration *config = [SKVisualAdviceConfiguration visualAdviceColor];
    config.streetType = streetType;
    config.countryCode = self.navigationInfo.currentCountryCode;
    config.routeStreetColor = [UIColor colorWithHex:color alpha:1.0];
    config.allowedStreetColor = [UIColor colorWithHex:color alpha:0.0f];
    config.forbiddenStreetColor = [UIColor colorWithHex:color alpha:0.0f];

    return config;
}
