Question

我的控制器中有一个带有2个UIViews的笔尖和2个带有IBOutlet的UILabel。

我正在增加和减少这些UIViews的高度看起来像一个条形，以指示什么时候是100％或更少 - 就像一个条形图差不多。

我对两个条形图（重复使用）使用以下方法，但是第一个UIView（条形）位置正确但第二个条形图太低 - Y轴错误。然而，两者的高度都是正确的。

有人有什么想法吗？我已经将它们定位在界面构建器中，我实际上在这个方法中所做的就是改变高度（基本上）

//Position the point, size and label of a rating bar
- (void)configureRatingBar:(UIView *)vRatingBar 
            andRatingLabel:(UILabel *)lRatingLabel
               usingRating:(NSDecimalNumber *)rating
{
    //NSDecimalNumber *foodRating = [self calculateRating:self.currentHotel.foodAndBeverageRating];
    NSString *formattedRating = [self formatRating:rating];
    lRatingLabel.text = formattedRating;

    float newHeight = [rating floatValue]; //The height will be based on the rating 100 max
    CGRect currentFrame = vRatingBar.frame; //Current frame of the rating view

    //CGPoint currentPoint = 
    //  [vRatingBar convertPoint:vRatingBar.frame.origin toView:vReviews];




    CGPoint currentPoint = vRatingBar.frame.origin; //Current point of the rating view
    float newYaxis = currentPoint.x + (100 - newHeight); //Y axis must move down with the decreasing rating from 0 (100 %) down

    [vRatingBar setFrame:CGRectMake(currentPoint.x, newYaxis, currentFrame.size.width, newHeight)]; 
    [lRatingLabel setFrame:CGRectMake(currentFrame.size.width / 34, newHeight - 20, 34, 21)];   

}

我看到你有这条线：

float newYaxis = currentPoint.x + (100 - newHeight); //Y axis must move down with the decreasing rating from 0 (100 %) down

使用currentPoint.x进行计算的位置。这应该是currentPoint.y吗？

UIView的定位不正确
