Question 1

How to add annotations to a panorama in CTPanoramaView?

Accepted Answer

Use the overlayView property to add custom UI elements on top of the panorama. However, you must manage touch events to ensure they don't block navigation, as mentioned in the README for touch-based controls.

Question 2

CTPanoramaView vs PanoramaGL for iOS?

Accepted Answer

CTPanoramaView uses SceneKit for better performance and native iOS integration, while PanoramaGL might offer more format support but can be less optimized. Choose CTPanoramaView for seamless SceneKit benefits if you don't need cubic or partial panoramas.

Question 3

How to customize the compass in CTPanoramaView?

Accepted Answer

Create a custom UIView subclass conforming to the CTPanoramaCompass protocol and implement updateUI(rotationAngle:fieldOfViewAngle:). Then set it to the compass property, as shown with CTPieSliceView in the example.

Question 4

Does CTPanoramaView support virtual reality mode?

Accepted Answer

No, it focuses on 2D panoramic viewing using SceneKit without built-in VR headset integration. For VR experiences, you'd need additional frameworks like ARKit or a dedicated VR library.

Question 5

How to handle touch conflicts with overlay views?

Accepted Answer

Ensure your overlay view does not consume touch events by setting isUserInteractionEnabled appropriately or overriding hitTest methods to pass touches to the underlying CTPanoramaView instance.

Question 6

CTPanoramaView performance on older iPhones?

Accepted Answer

SceneKit rendering is generally efficient, but complex panoramas might strain older devices. Optimize by using lower-resolution images or testing on target hardware, as performance isn't guaranteed for all scenarios.
