//设置导航栏的背景图片
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"tabBar.png"]forBarMetrics:UIBarMetricsDefault];

//自定义导航栏的标题
    UILabel *titleText = [[UILabel alloc] initWithFrame: CGRectMake(140, 0, 200, 50)];
    
    titleText.backgroundColor = [UIColor clearColor];
    
    titleText.textColor=[UIColor whiteColor];
    
    [titleText setFont:[UIFont systemFontOfSize:37.0]];
    
    [titleText setText:@"XXX"];
    
    self.navigationItem.titleView=titleText;
    
    [titleText release];

 // 自定义返回按钮
    UIBarButtonItem *backItem=[[UIBarButtonItem alloc]init];
    
    backItem.title=@"后退";
    
    backItem.tintColor=[UIColor redColor];
    
    self.navigationItem.backBarButtonItem = backItem;
    
    [backItem release];

@implementation MyCell
@synthesize label;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialization code

        label = [[UILabel alloc]initWithFrame:CGRectMake(250, 10, 70, 20)];
