Remarks

GameplayKit provides a number of pseudo-random number generators with a common interface for retrieving randomly-valued booleans, integers, and floats. There are also functions that shuffle properly. A T:GameKit.GKRandomSource instance can be used to construct a T:GameKit.GKRandomDistribution instance with a high-quality uniform, Gaussian, or shuffled distribution. GKRandomSource functions are not appropriate for use in cryptographic or security scenarios.

Constructors

GKRandomSource()

Default constructor, initializes a new instance of this class.

GKRandomSource(IntPtr)

A constructor used when creating managed representations of unmanaged objects; Called by the runtime.

GKRandomSource(NSCoder)

A constructor that initializes the object from the data stored in the unarchiver object.

GKRandomSource(NSObjectFlag)

Constructor to call on derived classes to skip initialization and merely allocate the object.
