附上部分代码：@implementation CustomBtn- (void)layoutSubviews {
    [super layoutSubviews];
    self.titleLabel.numberOfLines = 0;
    self.titleLabel.textAlignment = NSTextAlignmentCenter;

// 选中按钮
- (void)clickSegment:(id)sender {
    CustomBtn *btn = (CustomBtn *)sender;
    NSUInteger index = [_segmentArray indexOfObject:btn];
    
    [self.myDelagte buttonClick:index];
    [self updateSegmentState:index];
}

那设置选中状态的颜色呢？比如说点击的时候，找到btn上的label，点击btn的时候，把他的text颜色换了
        UILabel *label = (UILabel *)[self.view viewWithTag:201];
        label.textColor = [UIColor redColor];
