- [UITableViewCell setDefaultColor：]：无法识别的选择器发送到实例0x1092910e0

Question

这是我在这里总是找到答案之后的第一个问题但是无法解决这个问题，尽管我确信这有一个简单的答案。

我正在尝试将MCSwipeTableViewCell实现到我的项目中但我一直收到错误

  

- [UITableViewCell setDefaultColor：]：无法识别的选择器发送到实例0x1092910e0

如果我没有正确发布问题，请原谅我。

我所做的就是添加MCSwipeTableViewCell Pod

到目前为止，这是我的代码：

MasterViewController.h

#import <UIKit/UIKit.h>
#import "MCSwipeTableViewCell.h"

@interface MasterViewController : UITableViewController <UITableViewDataSource, UITableViewDelegate, MCSwipeTableViewCellDelegate>

@property(nonatomic) NSUInteger maximumNumberOfTouches;
@property(nonatomic) NSUInteger minimumNumberOfTouches;
@property (nonatomic, assign) NSUInteger nbItems;
@property (nonatomic, strong) MCSwipeTableViewCell *cellToDelete;


@end

MasterViewController.m

#import "MasterViewController.h"
#import "MCSwipeTableViewCell.h"
#import "DetailViewController.h"

static NSUInteger const kMCNumItems = 7;


@interface MasterViewController () <MCSwipeTableViewCellDelegate, UIAlertViewDelegate> {

    NSMutableArray *_objects;

}
@end

@implementation MasterViewController

- (id)initWithStyle:(UITableViewStyle)style {
    self = [super initWithStyle:style];
    if (self) {
        _nbItems = kMCNumItems;
    }
    return self;
}

- (void)awakeFromNib
{
    [super awakeFromNib];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.navigationItem.leftBarButtonItem = self.editButtonItem;

    UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject:)];
    self.navigationItem.rightBarButtonItem = addButton;

    UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
    [backgroundView setBackgroundColor:[UIColor whiteColor]];
    [self.tableView setBackgroundView:backgroundView];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)insertNewObject:(id)sender
{
    if (!_objects) {
        _objects = [[NSMutableArray alloc] init];
    }
    [_objects insertObject:[NSDate date] atIndex:0];
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
    [self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

    NSDate *object = _objects[indexPath.row];
    cell.textLabel.text = [object description];
    return cell;
}

我遇到了同样的问题，解决方案非常简单。您必须将单元格的自定义类设置为 MCSwipeTableViewCell 。

这是参考的截图。
