http://blog.csdn.net/hufeng825/article/details/7643532#）

.Label属性设置

    titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(, , , )];

    titleLabel.backgroundColor = [UIColor clearColor];//设置Label背景透明

    titleLabel.font = [UIFont boldSystemFontOfSize:];

    titleLabel.textColor = [UIColor colorWithRed:0.0/255.0 green:255.0/255.0 blue:0.0/255.0 alpha:];

    titleLabel.textAlignment = UITextAlignmentCenter;

    titleLabel.text = @"自定义标题";

.button属性设置

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

    [button setTitle:@"Button" forState:UIControlStateNormal];

    [button sizeToFit];

.在navigationItem中添加Label

   self.navigationItem.titleView = self.titleLabel;

.创建一个UIBarButtonItem用的方法主要有：

[UIBarButtonItem alloc]initWithTitle:(NSString *) style:(UIBarButtonItemStyle) target:(id) action:(SEL)

[UIBarButtonItem alloc]initWithBarButtonSystemItem:(UIBarButtonSystemItem) target:(id) action:(SEL)

   self.navigationItem.titleView = self.titleLabel;

.创建一个UIBarButtonItem用的方法主要有：

[UIBarButtonItem alloc]initWithTitle:(NSString *) style:(UIBarButtonItemStyle) target:(id) action:(SEL)

[UIBarButtonItem alloc]initWithBarButtonSystemItem:(UIBarButtonSystemItem) target:(id) action:(SEL)

 .在navigationItem中添加多个右按钮

定义一组button，将buttons放入array，再令rightBarButtonItems(注意有s) = array。

    UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:nil];

    UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:nil];

    UIBarButtonItem *button3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:nil];

    UIBarButtonItem *button4 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:nil];

    NSArray *array = [[NSArray alloc] initWithObjects:button1,button2,button3,button4, nil];

    self.navigationItem.rightBarButtonItems = array;

.设置NavigationBar背景颜色

self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:/ green:/ blue:/ alpha:];

.设置NavigationBar背景图片

    UIImage *title_bg = [UIImage imageNamed:@"title_bg"]; //获取图片

    CGSize titleSize = self.navigationController.navigationBar.bounds.size; //获取NavigationBar的位置和大小

    title_bg = [self scaleToSize: title_bg size:titleSize];

    //设置图片大小与NavigationBar相同

    [self.navigationController.navigationBar setBackgroundImage:title_bg forBarMetrics:UIBarMetricsDefault];

    //设置背景

//用于调整图片大小的方法

-(UIImage *) scaleToSize: (UIImage *) img size:(CGSize) size{

    UIGraphicsBeginImageContext(size);

    [img drawInRect:CGRectMake(, , size.width, size.height)];

    UIImage *scaledImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return scaledImage;

}

    UIBarButtonItem *button4 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:nil];
