使用prepareForReuse时，获取应用程序冻结并且单元格变空

Question

我已经尝试过prepareforreuse但是现在我的应用程序在滚动和单元格为空时卡住了。 我做错了吗？我的所有子视图都添加在XIB中。

指导我正确的解决方案。

    static NSString *cellIdentifier1 = @"pollCell";

    IXPollCustomCell *pollCell = (IXPollCustomCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier1];


    if (pollCell == nil) {

        pollCell = [[[NSBundle mainBundle] loadNibNamed:@"IXPollCustomCell" owner:self options:nil] objectAtIndex:0];
        pollCell.selectionStyle = UITableViewCellSelectionStyleNone;

IXPollCustomCell.m

   - (void)prepareForReuse
 {
[[self.contentView viewWithTag:2001] removeFromSuperview]; //Does not crash if the view is nil. It's okay to send messages to nil in ObjC

 }

IXPollCustomCell.h

    @property (weak, nonatomic) IBOutlet UIView *multiChoiceView;
    @property (weak, nonatomic) IBOutlet UIView *multiOption1View;
    @property (weak, nonatomic) IBOutlet UILabel *choice1RateLabel;
    @property (weak, nonatomic) IBOutlet UILabel *color1Label;
    @property (weak, nonatomic) IBOutlet UIButton *option1Button;
