单行显示为垂直

我有一个很长的文本字符串，我将其输入到UILabel进行显示。 UILabel动态设置为文本提供足够的空间

        specialities1 =[[UILabel alloc]init];
        [specialities1 setFrame:CGRectMake(124,218,size8.width, size8.height)];
        specialities1.backgroundColor=[UIColor clearColor];**strong text**
        specialities1.lineBreakMode=UILineBreakModeClip;
        specialities1.font=[UIFont fontWithName:@"Helvetica-Bold" size:14];
        specialities1.text=[NSString stringWithFormat:@"%@ ",temp ];
        specialities1.textAlignment=UITextAlignmentRight;
        [specialities1 setNumberOfLines:0];
        [specialities1 sizeToFit];
        [testscroll addSubview:specialities1];

我的问题是如果文本只包含单行，那么它显示为垂直中心对齐。 该对齐与我前面的相应标签不匹配。

使用下面的代码：

specialities1.lineBreakMode = UILineBreakModeWordWrap;
specialities1.textAlignment = UITextAlignmentLeft;

---

specialities1.textAlignment = UITextAlignmentLeft; // UITextAlignmentCenter

根据你遇到的情况选择你需要的东西。
