这里以监听播放按钮的点击为例:

获取对应的item, 并注册通知:

- (void)test {   
    SJEdgeControlButtonItem *playItem = [_player.defaultEdgeControlLayer.bottomAdapter itemForTag:SJEdgeControlLayerBottomItem_Play];
    [NSNotificationCenter.defaultCenter addObserver:self selector:@selector(itemActionDidPerformWithNote:) name:SJEdgeControlButtonItemPerformedActionNotification object:playItem];
}

实现通知回调:

- (void)itemActionDidPerformWithNote:(NSNotification *)note {
#ifdef DEBUG
    NSLog(@"%d - %s", (int)__LINE__, __func__);
#endif
}
