Question

我有正常单元格和工作成功的项目，但我想用自定义单元格更改它我将Cell.h和Cell.m文件添加到我的项目中，我需要将自定义单元格集成到我的工作单元格中。最后我想显示详细视图标题描述和图像（我添加了标题代码）我的代码在

下

Cell.h

#import <UIKit/UIKit.h>

@interface Cell : UITableViewCell

@property (nonatomic, weak) IBOutlet UIImageView *imaj;

@property (nonatomic, weak) IBOutlet UILabel *descriptionLabel;

@property (nonatomic, weak) IBOutlet UILabel *titleLabel;

@end

Cell.m

#import "Cell.h"

@implementation Cell

@synthesize imaj = _imaj;
@synthesize descriptionLabel = _descriptionLabel;
@synthesize titleLabel = _titleLabel;


@end

ViewController.m

#import "MasterViewController.h"
#import "DetailViewController.h"
#import "SDWebImage/UIImageView+WebCache.h"

在你的

中

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
Cell *cell;
// rest of your code 
}

会这样做。您已经使用了UITableViewCell，您需要将其替换为自定义单元类。

定制单元集成到工作单元中不起作用
