目前可以重写setupSubviews，这样解决
(void)setupSubviews{
[super setupSubviews];
/// 获取底部按钮，添加背景视图
for (UIView *subView in self.contentView.subviews) {
if ([subView isKindOfClass:UIButton.class]) {
UIButton * button = (UIButton *)subView;
[button setImage:[UIImage imageNamed:@"certificate_btn_right"] forState:UIControlStateNormal];
}
}
}
