UINavigationBar 上面添加多个按钮

http://xiaohui3837843.blog.163.com/blog/static/54388740201111615432445/

此方法已经验证，可行

UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 150, 45)]; 
[tools setTintColor:[self.navigationController.navigationBar tintColor]]; 
[tools setAlpha:[self.navigationController.navigationBar alpha]]; 
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:2];

UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd 
                        target:self action:@selector(clickSettings:)];

UIBarButtonItem *anotherButton1 = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UITabBarSystemItemContacts 
                                                        target:self action:@selector(clickEdit:)]; 
[buttons addObject:anotherButton]; 
[anotherButton release]; 
[buttons addObject:anotherButton1]; 
[anotherButton1 release]; 
[tools setItems:buttons animated:NO]; 
[buttons release]; 
UIBarButtonItem *myBtn = [[UIBarButtonItem alloc] initWithCustomView:tools]; 
self.navigationItem.rightBarButtonItem = myBtn;

[myBtn release]; 
[tools release];

次方法验证，暂时不可行，没查明原因

UIView * rightButtonParentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
 

  rightButtonParentView.backgroundColor = [UIColor clearColor];
    
    int buttonSize = 32;
    int rightOffset = 20;
    UIButton * setButton = [[UIButton alloc] initWithFrame:CGRectMake(rightButtonParentView.frame.size.width - buttonSize - rightOffset, 6, buttonSize, buttonSize)];
    [setButton setBackgroundImage:[UIImage imageNamed:@"star.png"] forState:UIControlStateNormal];
    [setButton addTarget:self action:@selector(NSlog) forControlEvents:UIControlEventTouchUpInside];
    [rightButtonParentView addSubview:setButton];
    [setButton release];
    
    UIButton * searchButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 6, buttonSize, buttonSize)];
    [searchButton setBackgroundImage:[UIImage imageNamed:@"star.png"] forState:UIControlStateNormal];
    [searchButton addTarget:self action:@selector(NSlog) forControlEvents:UIControlEventTouchUpInside];
    [rightButtonParentView addSubview:searchButton];
    [searchButton release];
    
    
    UIBarButtonItem * rightButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButtonParentView];
    [rightButtonParentView release];                            
    self.navigationItem.rightBarButtonItem = rightButtonItem;
    [rightButtonItem release];
