如何将标签添加到滚动视图

Question

我正在做一个关于如何将标签添加到滚动视图的小概念。我已经写了一个代码

但我的应用程序正在终止，但我不明白为什么它终止。可以帮助任何人解决这个问题....我的应用程序终止于插入第三个标签..

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)]; 

for(int i=0;i<[languageArray count];i++) 
{ 

    NSLog(@"array count is @%d",[languageArray count]); 
    languageLabel.text=[languageArray objectAtIndex:i]; 
    NSLog(@"array objectat index is @%@",[languageArray objectAtIndex:i]); 
    languageLabel.font=[UIFont systemFontOfSize:19.0]; 
    languageLabel.backgroundColor=[UIColor clearColor]; 
    [languageScrollView addSubview:languageLabel]; 
    // [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)];

下面修改后的代码尝试给我response..it工作

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


        for(int i=0;i<[languageArray count];i++) 
        { 
         UILabel *languageLabel=[[UILabel alloc]initWithFrame:CGRectMake(0, y ,90,30)]; 
         NSLog(@"array count is @%d",[languageArray count]); 
         languageLabel.text=[languageArray objectAtIndex:i]; 
         NSLog(@"array objectat index is @%@",[languageArray objectAtIndex:i]); 
         languageLabel.font=[UIFont systemFontOfSize:19.0]; 
         languageLabel.backgroundColor=[UIColor clearColor]; 
         [languageScrollView addSubview:languageLabel]; 
        // [languageScrollView addSubview:languageLabel]; 
         //y+=90;   
         y+=languageLabel.frame.size.height; 
         [languageLabel release]; 

        }
