设置Table Cell的背景图的类

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface UITableViewCell (UITableViewCellExt)

- (void)setBackgroundImage:(UIImage*)image;
- (void)setBackgroundImageByName:(NSString*)imageName;

@end


#import "UITableViewCellExt.h"


@implementation UITableViewCell (UITableViewCellExt)

- (void)setBackgroundImage:(UIImage*)image
{
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
    imageView.contentMode = UIViewContentModeCenter;
    self.backgroundView = imageView;
    [imageView release];
    
}

- (void)setBackgroundImageByName:(NSString*)imageName
{
    [self setBackgroundImage:[UIImage imageNamed:imageName]];
}


@end

调用示例：

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        
        [cell setBackgroundImageByName:@"text-background.png"];
        
        
    }
    
    return cell;
}
