Ich erhalte diese Werte aus dem Web. Dieser Bildschirm, wenn alle Werte aus dem Web stammen, sieht cool aus.

Und wenn keine Daten vorliegen, sieht es folgendermaßen aus.

Ich habe diesen Code verwendet

//Purchasae info
    {
        NSInteger heightToDecrease = 0;
        NSInteger heightToIncrease = 0;
        // NSInteger LABEL_HEIGHT = 18;

        maximumSize = CGSizeZero;
        textSize = CGSizeZero;

        //purchaseCostLabel
        heightToDecrease += self.PurchsCostHeightConstrains.constant;
        maximumSize = CGSizeMake(self.purchaseCostLabel.frame.size.width, 999);
        textSize = [UtilityHandler textSizeOfString:self.purchaseCostLabel.text font:self.purchaseCostLabel.font maxSize:maximumSize];
        NSInteger purchaseCostLabelHeight = textSize.height+SPACE_PADDING;
        self.PurchsCostHeightConstrains.constant = purchaseCostLabelHeight;
        totalHeightToIncrease += self.PurchsCostHeightConstrains.constant;

        //insurance
        heightToDecrease += self.insuranceHeightConstraints.constant;
        maximumSize = CGSizeMake(self.purchaseInsuranceLabel.frame.size.width, 999);
        textSize = [UtilityHandler textSizeOfString:self.purchaseInsuranceLabel.text font:self.purchaseInsuranceLabel.font maxSize:maximumSize];
        NSInteger insCostLabelHeight = textSize.height+SPACE_PADDING;
        self.insuranceHeightConstraints.constant = insCostLabelHeight;

        textSize = [UtilityHandler textSizeOfString:self.shippingLabel.text font:self.shippingLabel.font maxSize:maximumSize];
        NSInteger shippingLabelHeight = textSize.height+SPACE_PADDING;

        NSInteger conserLabelHeight = textSize.height+SPACE_PADDING;
        self.conserVHeightConstraints.constant = conserLabelHeight;
        totalHeightToIncrease += self.conserVHeightConstraints.constant;
        //storage

        NSInteger storagLabelHeight = textSize.height+SPACE_PADDING;
        self.storageHeightConstraints.constant = storagLabelHeight;
        totalHeightToIncrease += self.storageHeightConstraints.constant;
        //Frameing
        heightToDecrease += self.framingHeightConstraints.constant;
        maximumSize = CGSizeMake(self.shippingLabel.frame.size.width, 999);
        textSize = [UtilityHandler textSizeOfString:self.shippingLabel.text font:self.shippingLabel.font maxSize:maximumSize];

        self.framingHeightConstraints.constant = framLabelHeight;
        totalHeightToIncrease += self.framingHeightConstraints.constant;

        // set content view height constraint
        self.purchaseInformationViewHeightConstraint.constant -= heightToDecrease;
        // set content view height constraint
        self.purchaseInformationViewHeightConstraint.constant += heightToIncrease;


    }

Wie aktualisiere ich den Beschriftungsrahmen, damit Beschriftungen die Positionen leerer Beschriftungen annehmen können?
