在UINavigationBar下面添加一个小栏

Question

我想在我的应用程序中使用许多像这样的酒吧（我不知道如何命名它：包含“早期秀”“48小时”的酒吧）。

有没有一种简单的方法来创建这样的东西？使用的基本对象是什么？ 感谢。

AKAIK，SDK中没有任何内容可以帮助您。但是，UIScroll视图可以使用一些自定义UIButons和一个漂亮的蒙版图像来重现您在屏幕截图中显示的内容。

·H

IBOutlet UIScrollView *scrollView;

@property ( nonatomic , retain )  IBOutlet UIScrollView *scrollView;

-(void)AppleVijayAtFacebookDotCom:(id)sender;

-(void)createMenuWithButtonSize:(CGSize)buttonSize withOffset:(CGFloat)offset noOfButtons:(int)totalNoOfButtons;

的.m

@synthesize scrollView;



-(void)AppleVijayAtFacebookDotCom:(id)sender{


    NSLog(@"AppleVijayAtFacebookDotCom called");


    UIButton *button=(UIButton *)sender;


    if (button.tag == 0) {

        NSLog(@"hey have clicked first button, this is my tag : %i \n\n",button.tag);
    }
    else if (button.tag == 1) {

        NSLog(@"hey have clicked second button, this is my tag : %i \n\n",button.tag);

    }
    // ......like this

    NSLog(@"button clicked is : %iBut \n\n",button.tag);



}       



-(void)createMenuWithButtonSize:(CGSize)buttonSize withOffset:(CGFloat)offset noOfButtons:(int)totalNoOfButtons{

for (int i = 0; i < totalNoOfButtons; i++) {

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

    [button addTarget:self action:@selector(AppleVijayAtFacebookDotCom:) forControlEvents:UIControlEventTouchUpInside];

        //[button1 setImage:[UIImage imageNamed:@"Button.png"] forState:UIControlStateNormal];//with image

        //OR

    [button setTitle:[NSString stringWithFormat:@"%iBut",i] forState:UIControlStateNormal];//with title

    button.frame = CGRectMake(i*(offset+buttonSize.width), 8.0, buttonSize.width, buttonSize.height);

    button.clipsToBounds = YES;

    button.showsTouchWhenHighlighted=YES;

    button.layer.cornerRadius = 10;//half of the width

    button.layer.borderColor=[UIColor redColor].CGColor;

    button.layer.backgroundColor=[UIColor blackColor].CGColor;

    button.layer.borderWidth=2.0f;

    button.tag=i;

    [self.scrollView addSubview:button];

}

self.scrollView.contentSize=CGSizeMake((buttonSize.width + offset) * totalNoOfButtons, buttonSize.height);

    //self.navigationItem.titleView=self.scrollView;//if u have navigationcontroller then enable this line

}

不要忘记在界面构建器中连接scrollView

在IB中创建滚动视图时确保你的scrollView高度为44.这是导航栏的默认值。所以它看起来不错。

in viewDidLoad call 

[self createMenuWithButtonSize:CGSizeMake(70.0, 30.0) withOffset:20.0f noOfButtons:30];
