AI-generated Key Takeaways
-
GCKSessionTraits is an object describing the traits and capabilities of a session.
-
It includes properties for minimum and maximum volume, volume increment, and whether muting is supported.
-
It provides designated and convenience initializers to set these volume-related traits.
-
There is an instance method to check if the device has fixed volume.

Sets the volume range to [0.0, 1.0], the volume increment to 0.05 (5%), and the supportsMuting flag to YES.
| - (BOOL) isFixedVolume |
Whether this is a fixed volume device.
Property Detail
|
readnonatomicassign |
The minimum volume value.
Must be non-negative and less than or equal to the maximum volume.
|
readnonatomicassign |
The maximum volume value.
Must be non-negative and greater than or equal to the minimum volume.
|
readnonatomicassign |
The volume increment for up/down volume adjustments.
May be 0 to indicate fixed volume. Must be non-negative and less than or equal to the difference between the maximum volume and minimum volume.
|
readnonatomicassign |
Whether the audio can be muted.
