Delay Property

Summary

Gets the time remaining in the current wait state of an animation playback.

Syntax

Objective-C

C++/CLI

Python

public int Delay { get; }

@property (nonatomic, assign, readonly) NSUInteger delay;

public: 
property int Delay { 
   int get(); 
}

Delay # get  (RasterImageAnimator)

Property Value

Remarks

The delay is in milliseconds (ms).
