UITableView内容更改后滚动

我有自定义TableView动态填充自定义单元格，每个单元格包含2个按钮图像和2个标签。UITableView内容更改后滚动

当滚动我的表格视图和滚动回来按钮picures被改变。这是我的自定义单元格 .h文件中

class @interface CatalogCategoriesDetailsCell : UITableViewCell 
@property (nonatomic, weak) IBOutlet UIButton * firstStickerImageButton; 
@property (nonatomic, weak) IBOutlet UIButton *secondStickerImageButton; 
@property (strong, nonatomic) IBOutlet UILabel * firstStickerName; 
@property (strong, nonatomic) IBOutlet UILabel * secondStickerName; 
@end

.m文件

@implementation CatalogCategoriesDetailsCell 
@synthesize firstStickerImageButton = _firstStickerImageButton; 
@synthesize secondStickerImageButton = _secondStickerImageButton; 
@synthesize firstStickerName = _firstStickerName; 
@synthesize secondStickerName = _secondStickerName; 
@end

我TableViewControllerClass .h文件中

#import "CatalogCategoriesStickerDetails.h" 

@interface CatalogCategoriesDetails : UITableViewController 
{ 
    TagSingleton *sobj; 
} 

@property (strong,nonatomic) NSArray *categoryDetails; 
@property (strong,nonatomic) NSString *selectedCategoryId; 
@property (strong,nonatomic) NSMutableArray *categoryFileNames; 
@property (strong, nonatomic) NSString *documentsDirectory; 

@end

.m文件代码

{ 
    // Return the number of sections. 
    return 1;

我已经解决了这个问题，问题是我使用自己的索引而不是将单元格连接到[indexpath row]。 –
