SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components


I’m trying to convert Android (Java) code to iOS (Swift), and I need to create a custom SCIZoomPanModifier. In the android code, onFling, onDown, and onDown were overridden, but I can’t seem to do that in iOS. How can I override onFling, onDown, and onUp in iOS to mimic the android code?

Hello Yatharth

You can import protected API via the code below:

import SciChart.Protected.SCIChartModifierBase

and use it’s “internalHandleGesture:” method, in which you can handle different UIGestureRecognizer states.

For more information on how to create custom modifier – please see Custom Modifiers – the SCIGestureModifierBase API article in our documentation.

Hope that helps.

Best Regards,
Nazar R.
