OneTouchRotateGestureRecognizer Properties

Allows simultaneous execution if the platform specific views do no match. Default is true.

Angle threshold in radians that must be met before rotation starts - this is the amount of rotation that must happen to start the gesture. Default is 0.05.

Whether tracked touches are cleared when the gesture ends or fails, default is false. By setting to true, you allow the gesture to possibly execute again with a different touch even if the original touch it failed on is still on-going. This is a special case, so be sure to watch for problems if you set this to true, as leaving it false ensures the most correct behavior, especially with lots of gestures at once.

The current tracked touches for the gesture

Custom data for the gesture that you can attach, or just leave null if you don't need this This is useful if you want to retrieve this in a callback function, but it is not require for the gesture to work properly

Change in focus x in pixels

Change in focus y in pixels

The distance (in pixels) the gesture focus has moved from where it started along the x axis

The distance (in pixels) the gesture focus has moved from where it started along the y axis

Whether the gesture is Enabled. Default is true.

Focus x value in pixels (average of all touches)

Focus y value in pixels (average of all touches)

True if gesture is in process of restarting, false otherwise

The maximum number of touches to track. This gesture will never track more touches than this. Default is usually 1 or 2. Not all gestures will honor values higher than 1.

The minimum number of touches to track. This gesture will not start unless this many touches are tracked. Default is usually 1 or 2. Not all gestures will honor values higher than 1.

A platform specific view object that this gesture can execute in, null if none

The platform specific view scale (default is 1.0). Change this if the view this gesture is attached to is being scaled.

Average pressure of all tracked touches

Previous focus x

Previous focus y

Whether additional touches were added to the gesture since the last execute state.

If this gesture reaches the EndPending state and the specified gestures fail, this gestures will end. If the specified gesture begins, executes or ends, then this gesture will immediately fail.

Convenience method to add / remove one gesture to require failure on. Set to null to clear all require gestures to fail.

Whether the gesture should reset when it ends

The current rotation angle in degrees.

The change in rotation degrees.

The current rotation angle in radians.

The change in rotation radians.

The speed of the gesture in pixels using focus

Start focus x value in pixels (average of all touches)

Start focus y value in pixels (average of all touches)

Get the current gesture recognizer state

The gesture focus must change distance by this number of units from the start focus in order to start. Default is 0.0.

Whether the current number of tracked touches is within the min and max number of touches to track

Velocity x in pixels using focus

Velocity y in pixels using focus
