Declaration

@property(nonatomic, readonly, getter=isSuspended) BOOL suspended;

Discussion

Some devices disallow data capture due to a feature on the device.

For example, isSuspended returns YES for an external iSight camera when its privacy iris is closed, or for the internal iSight camera on a notebook when the notebook’s display is closed.

You can observe changes to the value of this property using Key-value observing.
