Question

我正在做一个关于如何向scrollview添加标签的小概念。我写了一段代码

但我的应用程序正在终止。但我无法理解为什么它会终止。可以帮助解决这个问题....我的应用程序终止插入第三个标签..

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)];

尝试使用以下修改过的代码

     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];

                    }
