将标签添加到条形图、核心图

Question

在添加标签时遇到问题。我通过在循环中传递数组并设置x&y轴的位置来静态添加标签。传递彩色图像数组和标签array..even。这里，获取颠倒的标签和颜色images..wat。问题可能是以下代码: be..down：

for( int i=0;i< [PieChartColorDescriptionArray count]; i++)
    {
        UIButton* blueButton=[UIButton buttonWithType:UIButtonTypeCustom];
        [blueButton setFrame:CGRectMake(165+80,65+(40*i),10,20)];
        [blueButton setTitle:@"" forState:UIControlStateNormal];
        [blueButton setAutoresizingMask:UIViewAutoresizingFlexibleWidth ];
        [blueButton setBackgroundImage:[UIImage imageNamed:[PieChartButtonImagesArray objectAtIndex:i]] forState:UIControlStateNormal];
        [blueButton setAutoresizingMask:AUTORESIZEMASK];
        [blueButton setUserInteractionEnabled:FALSE];
        [self.view addSubview:blueButton];
        [blueButton retain];
        UILabel* loLabel1=[[UILabel alloc]initWithFrame:CGRectMake(178+80,50+(40*i),50,50)];
        [loLabel1 setBackgroundColor:[UIColor clearColor]];
        [loLabel1 setTag:101];
        [loLabel1 setTextColor:[UIColor blackColor]];
        [loLabel1 setTextAlignment:UITextAlignmentCenter];
        [loLabel1 setAdjustsFontSizeToFitWidth:NO];
        [loLabel1 setNumberOfLines:1];
        [loLabel1 setFont:[UIFont systemFontOfSize:11]];
        [loLabel1 setText:[PieChartColorDescriptionArray objectAtIndex:i]];
       //loLabel1.transform=CGAffineTransformMakeRotation(-360.0);
        [loLabel1 setAutoresizingMask:AUTORESIZEMASK];
        [self.view addSubview:loLabel1];

        [loLabel1 retain];

    }

self.view是核心绘图托管视图吗？如果是这样的话，不要向其中添加任何子视图。相反，创建一个层次结构的视图，并在顶部创建某种容器视图。添加宿主视图以及标签和按钮作为容器视图的子视图。
