转：用Category类别来设置TableViewCell的背景图

直接上转载代码吧！

?

// UITableViewCellExt.h

 

@interface UITableViewCell (UITableViewCellEx)

- (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;

}
