ios - 自定义 UITableViewCell，重新排序时删除初始 View

Question

我有一个看起来像这样的自定义单元格

细胞

-ContainingView(称为cellframe)

--标签

--标签

包含 View 的原因是我可以在单元格周围设置阴影。

下面是我的代码

#import "QuickNoteMasterViewCell.h"
#import <QuartzCore/QuartzCore.h>

@interface QuickNoteMasterViewCell ()

@property (nonatomic, strong) CAShapeLayer *shapeLayer;

@end



@implementation QuickNoteMasterViewCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state

}

-(void)setEditing:(BOOL)editing{

}

// this adds shadow and border to the cell

- (void)configureBackgroundView
{
    UIView *cellFrame = self.cellFrame;
    //cellFrame.layer.borderColor = [UIColor whiteColor].CGColor;
    //cellFrame.layer.borderWidth = 10.;

    CGSize size = cellFrame.bounds.size;
    CGFloat curlFactor = 15.0f;
    CGFloat shadowDepth = 5.0f;
    cellFrame.layer.shadowColor = [UIColor blackColor].CGColor;
    cellFrame.layer.shadowOpacity = 1.f;
    cellFrame.layer.shadowOffset = CGSizeMake(.0f, 3.0f);
    cellFrame.layer.shadowRadius = 3.0f;
    cellFrame.layer.masksToBounds = NO;

    UIBezierPath *path = [UIBezierPath bezierPath];
    [path moveToPoint:CGPointMake(0.0f, 0.0f)];
    [path addLineToPoint:CGPointMake(size.width, 0.0f)];
    [path addLineToPoint:CGPointMake(size.width, size.height + shadowDepth)];
    [path addCurveToPoint:CGPointMake(0.0f, size.height + shadowDepth)
            controlPoint1:CGPointMake(size.width - curlFactor, size.height + shadowDepth - curlFactor)
            controlPoint2:CGPointMake(curlFactor, size.height + shadowDepth - curlFactor)];
    cellFrame.layer.shadowPath = path.CGPath;
}


- (void)layoutSubviews
{
    [super layoutSubviews];

    [self configureBackgroundView];

}



@end

问题是，当我重新排列单元格时，ContainingView(称为单元格框架)被移除。

有什么解决办法吗？

Answer 1

当 UITableViewCell 被重新排序时，TableView 将隐藏所有不是 UILabel 或 UIImageView 的东西。

不太清楚它为什么这样做，但我不知道有什么办法可以解决这个问题。我知道唯一可行的方法是将阴影 View 创建为图像并将 UIView 切换为 UIImageView。

对不起!
