objective-c – Grand Central Dispatch(GCD)Key-Value Observin

- (void) method
{
    [currentPlayer addObserver:self forKeyPath:@"some" options:some context:some];
}

所有更改都以这些方法处理：

- (void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context

如果我将我的方法修改为：

- (void) method
{
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH,0),^{
        [currentPlayer addObserver:self forKeyPath:@"some" options:some context:some];
    });
}

这是否意味着 – (void)observeValueForKeyPath …将在DISPATCH_QUEUE_PRIORITY_HIGH中工作？

附：我希望KVO能够在DISPATCH_QUEUE_PRIORITY_HIGH中工作.

编辑：

我观察AVPlayer变量.如：

[currentPlayer addObserver:self forKeyPath:@"currentItem.loadedTimeRanges" options:NSKeyValueObservingOptionNew context:kTimeRangesKVO];

这些变量会自动更改.

每次调用“observeValueForKeyPath”时我都会检查队列,它仍然是dispatch_get_main_queue(),我不知道如何将其更改为其他队列.
