Question

我在一个视图中使用了4个UILabel。

-(void)setQuestion{
Challenge = [[[UILabel alloc] initWithFrame:CGRectMake(16, 70, 294, 150)] autorelease];
Challenge.text = challengetext ;
Challenge.lineBreakMode = UILineBreakModeWordWrap;
Challenge.backgroundColor = [UIColor clearColor];
[self.view addSubview:Challenge];

Question = [[[UILabel alloc] initWithFrame:CGRectMake(16, 100 + Challenge.frame.size.height, 294, 150)] autorelease];
Question.text = activeQuestion ;
Question.lineBreakMode = UILineBreakModeWordWrap;
Question.backgroundColor = [UIColor clearColor];
[self.view addSubview:Question];

Answer = [[[UILabel alloc] initWithFrame:CGRectMake(16, 130 + Challenge.frame.size.height + Question.frame.size.height , 294, 150)] autorelease];
Answer.text = [theQuiz objectAtIndex:row+1] ;
Answer.lineBreakMode = UILineBreakModeWordWrap;
Answer.backgroundColor = [UIColor clearColor];
[self.view addSubview:Answer];

Description = [[[UILabel alloc] initWithFrame:CGRectMake(16, 160 + Challenge.frame.size.height + Question.frame.size.height + Answer.frame.size.height , 294, 150)] autorelease];
Description.text = [theQuiz objectAtIndex:row+2] ;
Description.lineBreakMode = UILineBreakModeWordWrap;
Description.backgroundColor = [UIColor clearColor];
[self.view addSubview:Description];
}

下一个问题有一个按钮。

-(IBAction)next{

[scrollview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO]; 
NSInteger endOfQuiz = [theQuiz count];
//[Challenge setHidden:YES];
if((((questionNumber - 1) * 4) + 4) == endOfQuiz)
{
    restartGame = YES;


}else
{
        [self setQuestion];        
}
}

当我点击下一个按钮时，我从我的文本文件中得到了下一个问题但问题是我每次点击标签重叠上的文字。

我该怎么做？

谢谢..

在执行removeFromSuperview之前尝试[self setQuestion]您的标签：

- (IBAction)next {

    [scrollview scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO]; 
    NSInteger endOfQuiz = [theQuiz count];
    //[Challenge setHidden:YES];
    if((((questionNumber - 1) * 4) + 4) == endOfQuiz) {
        restartGame = YES;
    } else {
        [Challenge removeFromSuperview];
        [Question removeFromSuperview];
        [Answer removeFromSuperview];
        [Description removeFromSuperview];
        [self setQuestion];        
    }
}
