以編程方式將UILabels彼此相鄰放置

Question

我有三個不同寬度的UILabels，我想排列在一起。我如何更新框架的X值？

這是我有：

UILabel *contractLabel = (UILabel *) [cell viewWithTag:200]; 
contractLabel.text = [board getDisplayLevel]; 

UILabel *contractSuit = (UILabel *) [cell viewWithTag:201]; 
contractSuit.text = [board getDisplayStrain]; 
contractSuit.textColor = [board getDisplayStrainColor]; 
contractSuit.hidden = NO; 
contractSuit.frame = CGRectMake(contractSuit.frame.origin.x = contractLabel.frame.origin.x + contractLabel.bounds.size.width + 3, contractSuit.frame.origin.y, contractSuit.frame.size.width, contractSuit.frame.size.height); // line 121 

UILabel *contractTail = (UILabel *) [cell viewWithTag:202]; 
contractTail.text = [board getDisplayContract]; 
contractTail.hidden = NO; 
contractTail.frame.origin.x = contractSuit.frame.origin.x + contractSuit.bounds.size.width + 3; // line 127 

都分配到幀失敗：

ViewBoards_ViewController.m:121: error: lvalue required as left operand of assignment 
ViewBoards_ViewController.m:127: error: lvalue required as left operand of assignment 

我在做什麼錯？謝謝。

你有一個簡單的拼寫錯誤

contractSuit.frame = CGRectMake(contractSuit.frame.origin.x = contractLabel.frame.origin.x + contractLabel.bounds.size.width + 3, contractSuit.frame.origin.y, contractSuit.frame.size.width, contractSuit.frame.size.height); 

應該

contractSuit.frame = CGRectMake(contractSuit.frame.origin.x + contractLabel.frame.origin.x + contractLabel.bounds.size.width + 3, contractSuit.frame.origin.y, contractSuit.frame.size.width, contractSuit.frame.size.height);
