I'm trying to subclass SChartCrosshairTooltip with 2.2.1 version of Shinobi Chart Library:
#import <UIKit/UIKit.h>
#import <ShinobiCharts/SChartCrosshairTooltip.h>
@interface Tooltip : SChartCrosshairTooltip
@end
No matter what I do, I always get this error:
ShinobiCharts Trial 2.2.1/Demos/LineChart/ShinobiCharts.embeddedframework/ShinobiCharts.framework/Headers/SChartCrosshairTooltip.h:21:5: Unknown type name 'SChartCrosshairStyle'; did you mean 'SChartCrosshairTooltip'?
as if it was impossible to subclass the SChartCrosshairTooltip differently from what documentation says.
I cannot switch to newer versions of the library (now is 2.5.0), but I really need to customize the crosshair tooltip.
The reason that this isn't working is because SChartCrosshairStyle is forward-defined in SChartCrosshairTooltip. I think that you could get around this by adding an import for SChartCrosshairStyle:
#import <UIKit/UIKit.h>
#import <ShinobiCharts/SChartCrosshairStyle.h>
#import <ShinobiCharts/SChartCrosshairTooltip.h>
...however, there are other forward definitions inside SChartCrosshairTooltip, so I suspect that you will get other unknown class issues.
The recommended way is to use the common Shinobi header import:
#import <ShinobiCharts/ShinobiChart.h>
This will import all the relevant classes.
