主要实现的代码如下：

self.rateInfoView是定义好的控制属性控件可以改变透明度的值来改变毛玻璃透明的效果

// 虚拟交易费率弹窗- (void)showRateInfo{            self.rateInfoView = [[UIView alloc]initWithFrame:self.windowView.frame];    //    rateInfoView.backgroundColor = [UIColor blackColor];    self.rateInfoView.alpha = 0.f;    [self.view addSubview:self.rateInfoView];        //  创建需要的毛玻璃特效类型        UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleDark];        //  毛玻璃view 视图        UIVisualEffectView *effectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];        //添加到要有毛玻璃特效的控件中        effectView.frame = self.windowView.frame;        [self.rateInfoView addSubview:effectView];        //设置模糊透明度        effectView.alpha = .8f;        UIImageView *rateImage = [[UIImageView alloc]initWithFrame:CGRectMake(Width*0.1, (Height-Width*0.8*1.11)/2+20, Width*0.8, Width*0.8/1.11)];    rateImage.image = [UIImage imageNamed:@"虚拟费率弹窗"];    [self.rateInfoView addSubview:rateImage];        UIButton *closeInfo = [UIButton buttonWithType:UIButtonTypeCustom];    closeInfo.frame     = CGRectMake(Width*0.9-22-12, (Height-Width*0.8*1.11)/2+20+12, 22, 22);    [closeInfo setImage:[UIImage imageNamed:@"cancel"] forState:UIControlStateNormal];    [closeInfo addTarget:self action:@selector(closeRate) forControlEvents:UIControlEventTouchUpInside];    [self.rateInfoView addSubview:closeInfo];        [UIView animateWithDuration:0.2 animations:^{        self.rateInfoView.alpha = 1.0f;    }];        }- (void)closeRate{        [self.rateInfoView removeFromSuperview];    }

效果图如下：
