CollectionView的cell长按事件实现

原生cell没有长按事件，我们需要使用手势识别来绑定CollectionView。创建并绑定CollectionView如下：

 (void)viewDidLoad {
  [super viewDidLoad];

*/

  //创建长按手势监听
  UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc]
                                             initWithTarget:self
                                             action:@selector(myHandleTableviewCellLongPressed:)];
  longPress.minimumPressDuration = 1.0;
  //将长按手势添加到需要实现长按操作的视图里
  [self.collectionView addGestureRecognizer:longPress];

处理长按事件：

 (void) myHandleTableviewCellLongPressed:(UILongPressGestureRecognizer *)gestureRecognizer {

  CGPoint pointTouch = [gestureRecognizer locationInView:self.collectionView];

  if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
    NSLog(@"UIGestureRecognizerStateBegan");

    NSIndexPath *indexPath = [self.collectionView indexPathForItemAtPoint:pointTouch];
    if (indexPath == nil) {
      NSLog(@"空");
    }else{

      NSLog(@"Section = %ld,Row = %ld",(long)indexPath.section,(long)indexPath.row);

    }
  }
  if (gestureRecognizer.state == UIGestureRecognizerStateChanged) {
    NSLog(@"UIGestureRecognizerStateChanged");
  }

  if (gestureRecognizer.state == UIGestureRecognizerStateEnded) {
    NSLog(@"UIGestureRecognizerStateEnded");
  }
}
