    static NSString *simpleTableIdentifier = @"SimpleCell";
    SimpleCell *cell = (SimpleCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
    if (cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SimpleCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }

    //[sender setBackgroundImage:[UIImage imageNamed:@"swipe.png"] forState:UIControlStateNormal];
    sender.tag = indexPath.row;

    titleString =@"Send A Gift";
    UITableViewRowAction *sendAGift = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleNormal title:titleString handler:^(UITableViewRowAction *action, NSIndexPath *indexPath){
       // [self deleteMail:[NSArray arrayWithObject:indexPath]:YES];

    }];

    [sendAGift setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"swipe.png"]]];



    return @[sendAGift];
}

推荐答案

我认为你的班级 SimpleCell 应包含UIButton，以便正确执行重用。

I think your class SimpleCell should contain the UIButton, in order perform reusing correctly.

如果您创建一个自定义 UITableViewCell ，它包含单元格上的所有UI操作并运行它们会更简单在单元格内，而不是 UITableView 本身。

It will be simpler if you create a custom UITableViewCell that contains all the UI actions over the cell and operate them within the cell, not in the UITableView itself.

让我们看一个例子：

这是customCell.h文件：

Here's the customCell.h file:

@interface customCell : UITableViewCell {
    UIButton *buttonSwipe;
}
@end

这是customCell.h文件：

Here's the customCell.h file:

#import "customCell.h"

@implementation customCell

- (instancetype) initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self) {
        [self commonInit];
    }

    return self;
}

- (instancetype) initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        [self commonInit];
    }

    return self;
}

- (instancetype)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        [self commonInit];
    }

    return self;
}

- (void) commonInit {
    buttonSwipe = [UIButton... // Initialize here your button
    [buttonSwipe addTarget:self action:@selector(swipeCell:) forControlEvents:UIControlEventTouchUpInside]; 
}

- (void) swipeCell {
    // Embed here the code that makes the effect of swipe the cell.
}

这是一个快速未经测试的解决方法，带有一些预定义的代码，但我认为它是一个工作示例，如果你想让你的单元格用你自己的代码刷

This is a fast-untested workaround with some predefined code, but I think it's a working example if you want to make your cells swipe with your own code.

但如果你想要更快的方式，我建议你去访问上的 Chris Wendel 和他的 SWTableViewCell GitHub
