ios tableview/collectionView关于点击cell后 刷新cell
用数组记录点击cell的索引值,然后用数组的- (BOOL)containsObject:(ObjectType)anObject;这个方法判断该点击cell的索引值是否在数组中,来进行相应的操作。

WLSelectSeatCollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:seatCell forIndexPath:indexPath];
cell.titleLabel.text = [NSString stringWithFormat:@"%ld",indexPath.row +1];
if ([self.seatArray containsObject:indexPath])
{
cell.titleLabel.textColor = [UIColor redColor];
cell.titleLabel.layer.borderColor = [UIColor redColor];
}
else
{
cell.titleLabel.textColor = [UIColor lightGrayColor];
cell.titleLabel.layer.borderColor = [UIColor lightGrayColor].CGColor;
}
return cell;
