Instance Property


The number of frames that must pass before the display link notifies the target again.


@property(nonatomic) NSInteger frameInterval;


The default value is 1, which results in your application being notified at the refresh rate of the display. If the value is set to a value larger than 1, the display link notifies your application at a fraction of the native refresh rate. For example, setting the interval to 2 causes the display link to fire every other frame, providing half the frame rate.

Setting this value to less than 1 results in undefined behavior and is a programmer error.
