ios - 向条形图、核心图添加标签

Question

嗨，M 在添加标签时遇到问题..M 通过在循环内传递数组并设置 x &y 轴的位置来静态添加标签..m 传递彩色图像数组和标签数组..即使在这里 M 得到颠倒的标签和彩色图像。 .wat 问题可能是..down 是代码:

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];

    }

是 self.view Core Plot 托管 View ？如果是这样，请不要向其添加任何 subview 。相反，创建一个 View 层次结构，顶部有某种容器 View 。添加托管 View 以及您的标签和按钮作为容器 View 的 subview 。
