【问题描述】：

我是 iphone 编程新手。我在 iTunes 上浏览不同的应用程序。找到了这个很棒的菜单。你们能帮我理解在技术上要做什么来实现这个菜单吗？

用户可以从左向右滑动此菜单，反之亦然，而不会影响底部的视图。如何做到这一点？提前致谢

【解决方案1】：

IBOutlet UIScrollView *scrollView;

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

-(void)AppleVijayAtFacebookDotCom:(id)sender;

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

@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

}

不要忘记在界面生成器中连接scrollView

在 IB 中创建滚动视图时，确保您的滚动视图高度为 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];
