iphone - 单行显示为垂直居中对齐

Question

我有一个很长的文本字符串，我将其输入到一个UILabel显示中。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，那么它会显示为垂直居中对齐。该对齐方式与我前面的相应标签不匹配。

Answer 1

使用以下代码：

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

Answer 2

specialities1.textAlignment = UITextAlignmentLeft; // UITextAlignmentCenter

根据你遇到的情况选择你需要的。
