#pragma mark -----------------4个选择label的创建---------------------
- (UILabel *)firstLabel {
    if (!_firstLabel) {
        _firstLabel = [self createLabelWithy:70];
    }
    return _firstLabel;
}

- (UILabel *)secondLabel {
    if (!_secondLabel) {
        _secondLabel = [self createLabelWithy:(self.firstLabel.frame.origin.y+self.firstLabel.frame.size.height+10)];
    }
    return _secondLabel;
}

- (UILabel *)thirdLabel {
    if (!_thirdLabel) {
        _thirdLabel = [self createLabelWithy:(self.secondLabel.frame.origin.y+self.secondLabel.frame.size.height+10)];
    }
    return _thirdLabel;
}

- (UILabel *)fourthLabel {
    if (!_fourthLabel) {
        _fourthLabel = [self createLabelWithy:(self.thirdLabel.frame.origin.y+self.thirdLabel.frame.size.height+10)];
    }
    return _fourthLabel;
}

#pragma mark -----------------四个单选label自适应高度的方法-------------------
- (CGRect)adaptHeightWithFrame:(CGRect)frame  andText:(NSString *)text {
    CGRect frameOne = frame;
    CGRect rect = [text boundingRectWithSize:CGSizeMake(268.5, 1000)
                                     options:NSStringDrawingUsesLineFragmentOrigin
                                  attributes:@{NSFontAttributeName: [UIFont systemFontOfSize:11]}
                                     context:nil];
    frameOne.size.height = rect.size.height;
    return frameOne;
}

#pragma mark 创建四个label的方法
- (UILabel *)createLabelWithy:(CGFloat)y {
    
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(WIDTHADP*51.5, y, WIDTHADP*268.5, 0)];
    label.numberOfLines = 0;
    label.backgroundColor = [UIColor orangeColor];
    label.font = [UIFont systemFontOfSize:11.0];
    label.textColor = RGB_COLOR(120, 120, 120);
    return label;
}

整体思路：

1. 首先用方法自动创建label，可以先固定一些固定属性，如果是横排可传x
#pragma mark 创建四个label的方法
- (UILabel *)createLabelWithy:(CGFloat)y {
    
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(WIDTHADP*51.5, y, WIDTHADP*268.5, 0)];
    label.numberOfLines = 0;
    label.backgroundColor = [UIColor orangeColor];
    label.font = [UIFont systemFontOfSize:11.0];
    label.textColor = RGB_COLOR(120, 120, 120);
    return label;
    
}
2. 用懒加载加载竖排的label，用创建label方法创建
#pragma mark 四个选择单选框对应的lable
@property (nonatomic,retain) UILabel *firstLabel; //第一个对应的label
@property (nonatomic,retain) UILabel *secondLabel;
@property (nonatomic,retain) UILabel *thirdLabel;
@property (nonatomic,retain) UILabel *fourthLabel;

#pragma mark -----------------4个选择label的创建---------------------
- (UILabel *)firstLabel {
    if (!_firstLabel) {
        _firstLabel = [self createLabelWithy:70];
    }
    return _firstLabel;
}

- (UILabel *)secondLabel {
    if (!_secondLabel) {
        _secondLabel = [self createLabelWithy:(self.firstLabel.frame.origin.y+self.firstLabel.frame.size.height+10)];
    }
    return _secondLabel;
}

- (UILabel *)thirdLabel {
    if (!_thirdLabel) {
        _thirdLabel = [self createLabelWithy:(self.secondLabel.frame.origin.y+self.secondLabel.frame.size.height+10)];
    }
    return _thirdLabel;
}

- (UILabel *)fourthLabel {
    if (!_fourthLabel) {
        _fourthLabel = [self createLabelWithy:(self.thirdLabel.frame.origin.y+self.thirdLabel.frame.size.height+10)];
    }
    return _fourthLabel;
}
3. label的加载：先对label进行赋值，然后自适应方法改变frame，最后添加到需要添加的地方
