Snapshot fidelity: Combining Visual Effects with Filters

Section titled Snapshot fidelity: Combining Visual Effects with Filters

Symptom: Some elements of the snapshots may not be visible (e.g UITabBar buttons).

Explanation: Our capturing method prevents to capture views when Visual effects are combined with filters. Our tools captures as much as Xcode’s ‘Debug View Hierarchy’ feature. If you want to preview what is going to be rendered, you can use this feature to visualize your screen. Capturing a Snapshot of a UIVisualEffectView.

Gestures not attached to UIImageView

Section titled Gestures not attached to UIImageView

Symptom: When analysing the tap rate on an image, we see 0% when we know it is not possible.

Explanation: By default UIImageView have their isUserInteractionEnabled property set to false (See Apple documentation). This means that the UIImageView won’t receive any input event. All events will be handled by the first parent to have isUserInteractionEnabled set to true (usually the first parent will do).

Workaround: Create a zone on the parent view to get the taps on the image.
