重用UIView

Question

我有一个UIView，根据用户在某个级别上的表现显示图像，然后用户可以选择继续到下一个级别，一旦完成了那个，UIView再次显示依赖于图像他们做得多好

我在用户决定要进入下一级并且在UIView内部之后释放UIView我很确定在完成它之后我会释放所有内容但是当第二次加载UIView时从第一次起仍然存在，第二个图像放在它上面，所以你可以同时看到两个图像。

我不确定为什么会这样，就像我说我很确定我在UIView中发布了所有内容然后在用户完成后释放UIView

我使用Interface Builder

创建了UIView

任何帮助将不胜感激

//this is the code to access the UIView
-(void)DisplayStatsForLevel:(NSInteger)level ScoreEarned:(NSInteger)pScore NumberHit:(NSInteger)pNumberHit TotalTargets:(NSInteger)pTotalTargets MedalEarned:(NSInteger)pMedalEarned BulletsFired:(NSInteger)pBulletsFired
{
switch(level)
{
    case 1: 
        [levelOne removeFromSuperview];
        [levelOne release]; levelOne = nil;
        [self.view addSubview:levelComplete];
        [levelComplete SetupScreen:pScore NumberHit:pNumberHit TotalTargets:pTotalTargets MedalEarned:pMedalEarned BulletsFired:pBulletsFired];
        break;
    case 2:
        [levelTwo removeFromSuperview];
        [levelTwo release]; levelTwo = nil;
        [self.view addSubview:levelComplete];
        [levelComplete SetupScreen:pScore NumberHit:pNumberHit TotalTargets:pTotalTargets MedalEarned:pMedalEarned BulletsFired:pBulletsFired];
        break;
    default:
        break;
}

}

//this is the code that releases the UIView
-(void)NextLevel:(NSInteger)nextLevel
{
switch (nextLevel)
{
    case 2:
        [levelComplete removeFromSuperview];
        [levelComplete release]; levelComplete = nil;
        [self.view addSubview:levelTwo];
        [levelTwo SetupLevel];
        break;
    default:
        break;
}

}

//this is the code that displays the image
switch (medalWon)
{
    case 1:
        medalImage = [UIImage imageNamed:@"Bronze.png"];
        break;
    case 2:
        medalImage = [UIImage imageNamed:@"Silver.png"];
        break;
    case 3:
        medalImage = [UIImage imageNamed:@"Gold.png"];
        break;
    case 4:
        medalImage = [UIImage imageNamed:@"Platinum.png"];
        break;
    default:
        break;
}

medal =[[UIImageView alloc] initWithFrame:medalFrame];
medal.image = medalImage;
[medalImage release];
[medal setNeedsDisplay];

[self addSubview:medal];

Answer 1

我刚才尝试了类似的东西，为了获得两个重叠的图像，我不得不称之为两次：

medal = [[UIImageView alloc] initWithFrame：medalFrame]; medal.image = medalImage; [medalImage发布]; [medal setNeedsDisplay];

[self addSubview：medal];

你能检查一下你是否这样做吗？
