动态更新UILabel在UIView上的位置取决于它们的文本值

我从网上获取这些值。 如果所有值都来自网络，看起来很酷，这个屏幕。

在没有数据的情况下，它看起来如下。

我用过这段代码

//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; totalHeightToIncrease += self.insuranceHeightConstraints.constant; //shipping heightToDecrease += self.shippingHeightConstarants.constant; maximumSize = CGSizeMake(self.shippingLabel.frame.size.width, 999); textSize = [UtilityHandler textSizeOfString:self.shippingLabel.text font:self.shippingLabel.font maxSize:maximumSize]; NSInteger shippingLabelHeight = textSize.height+SPACE_PADDING; self.shippingHeightConstarants.constant = shippingLabelHeight; totalHeightToIncrease += self.shippingHeightConstarants.constant; //conservation heightToDecrease += self.conserVHeightConstraints.constant; maximumSize = CGSizeMake(self.conservationLabel.frame.size.width, 999); textSize = [UtilityHandler textSizeOfString:self.conservationLabel.text font:self.conservationLabel.font maxSize:maximumSize]; NSInteger conserLabelHeight = textSize.height+SPACE_PADDING; self.conserVHeightConstraints.constant = conserLabelHeight; totalHeightToIncrease += self.conserVHeightConstraints.constant; //storage heightToDecrease += self.storageHeightConstraints.constant; maximumSize = CGSizeMake(self.storageLabel.frame.size.width, 999); textSize = [UtilityHandler textSizeOfString:self.storageLabel.text font:self.storageLabel.font maxSize:maximumSize]; 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]; NSInteger framLabelHeight = textSize.height+SPACE_PADDING; 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; } 

那么如何更新标签框架，以便任何标签可以采用空白标签的位置？

使用Storyboard作为标签并仅使用单个标签将标签设置为具有所有4个约束，左，右，上，下设置行数0.它适用于您的文本
