- Parameters
-
Вызывается, когда очередь полностью перезагружена.
Любые ранее использованные элементы очереди следует считать недействительными.
- Parameters
-
| - (void) mediaQueue: |
|
( GCKMediaQueue *) |
queue |
| didInsertItemsInRange: |
|
(NSRange) |
range |
|
|
| |
|
optional |
Вызывается, когда в очередь вставлен непрерывный диапазон элементов очереди.
- Parameters
-
| queue | The queue. |
| range | The range indicating the starting index and count of items inserted. |
| - (void) mediaQueue: |
|
( GCKMediaQueue *) |
queue |
| didUpdateItemsAtIndexes: |
|
(NSArray< NSNumber * > *) |
indexes |
|
|
| |
|
optional |
Вызывается, когда в очереди обновляется один или несколько элементов очереди.
Это включает в себя случай, когда ранее доступные, но недоступные элементы были извлечены и помещены в кэш, а также случай, когда ранее кэшированные элементы были удалены из кэша.
- Parameters
-
| queue | The queue. |
| indexes | The ordered list of indexes of the items that have been updated. |
| - (void) mediaQueue: |
|
( GCKMediaQueue *) |
queue |
| didRemoveItemsAtIndexes: |
|
(NSArray< NSNumber * > *) |
indexes |
|
|
| |
|
optional |
Вызывается, когда один или несколько элементов очереди были удалены из очереди.
- Parameters
-
| queue | The queue. |
