在UINavigationBar下面添加一個小酒吧

Question

我想在我的應用程序中使用很多像這樣的酒吧（我不知道如何命名它：包含「早期秀」「48小時」的酒吧）。

有沒有簡單的方法來創建這樣的東西？什麼是基本對象使用？ 謝謝。

Answer 1

AKAIK，沒有什麼，這是否適合您的SDK。但是，可以使用UIScroll視圖以及一些自定義UIButons和漂亮的蒙版圖像來重現您在屏幕截圖中顯示的內容。

.H

IBOutlet UIScrollView *scrollView; 

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

-(void)AppleVijayAtFacebookDotCom:(id)sender; 

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

.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 

}

不要忘記了滾動連接在Interface Builder

雖然在IB創建滾動視圖確保你的scrollView高度是44.這是默認導航bar.so它會看起來不錯。

in viewDidLoad call 

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