这一切的基础设施 UITableView更好

UILabel不是交互式组件Girish。所以你不能得到它的选择事件。更好地使用UIButtons。 我编辑了您的代码并添加了一个方法。只需使languageArray全局和代码工作正常。

-(void)youMethod 
{ 
    //int y=0; 
    //NSMutableArray *languageArray=[[NSMutableArray alloc]initWithObjects:@"Chinese",@"Spanish",@"English",@"Arabic",@"Hindi",@"Bengali",@"Portuguese",@"Russian",@"Japanese",@"German",nil]; 
    //UILabel *languageLabel=[[UILabel alloc]initWithFrame:CGRectMake(0, y ,90,30)]; 

    languagValue=0; 

    int y=0; 
    NSMutableArray *languageArray=[[NSMutableArray alloc]initWithObjects:@"Chinese",@"Spanish",@"English",@"Arabic",@"Hindi",@"Bengali",@"Portuguese",@"Russian",@"Japanese",@"German",nil]; 


    for(languagValue=0;languagValue<[languageArray count];languagValue++) 
    { 
     UILabel *languageLabel=[[UILabel alloc]initWithFrame:CGRectMake(0, y ,90,30)]; 
     UIButton * btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
     btn.frame = CGRectMake(0, y ,90,30); 
     btn.tag = languagValue; 
     [btn addTarget:self action:@selector(languageSelected:) forControlEvents:UIControlEventTouchUpInside]; 
     NSLog(@"array count is @%d",[languageArray count]); 
     languageLabel.text=[languageArray objectAtIndex:languagValue]; 
     NSLog(@"array objectat index is @%@",[languageArray objectAtIndex:languagValue]); 
     languageLabel.font=[UIFont systemFontOfSize:19.0]; 
     languageLabel.backgroundColor=[UIColor clearColor]; 
     [languageScrollView addSubview:languageLabel]; 
     [languageScrollView addSubview:btn]; 
     // [languageScrollView addSubview:languageLabel]; 
     //y+=90;   
     y+=languageLabel.frame.size.height; 
     [languageLabel release]; 

     } 
     [languageScrollView setShowsHorizontalScrollIndicator:NO]; 
     [languageScrollView setShowsVerticalScrollIndicator:NO]; 

     [languageScrollView setContentSize:CGSizeMake(genderScrollView.frame.size.width, y)]; 

} 

-(void)languageSelected:(id)sender 
{ 
    UIButton * btn = (UIButton*)sender; 
    int selectedIndex = btn.tag; 
    NSString * selectedLanguage = [languageArray objectAtIndex:selectedIndex]; 
}

，必须有人已经设定了这些价值观，不是吗？ :)为什么你会问标签的价值，当你已经必须知道它设置它的第一位。

编辑：看到你的代码，你大概可以从滚动视图的contentOffset弄清楚，但似乎你会用UIPicker或者免费提供
