blocks|key|3143223|text|不可能垂直对齐UILabel中的文本。但是，您可以使用sizeWithFont:+NSString的方法动态地更改标签的高度，只需根据需要设置其x和y。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3143224|作为一种替代，您可以使用UITextField。它支持contentVerticalAlignment+peoperty，因为它是UIControl的子类。您必须将其userInteractionEnabled设置为否，以防止用户在其上键入文本。|3143225|entityMap^0|R|N|0|C|B|R|O|1T|9|2B|M|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|I|$]]

Its impossible to align the text in UILabel vertically. But, you can dynamically change the height of the label using sizeWithFont: method of NSString, and just set its x and y as you want.

As an alternative you can use UITextField. It supports the contentVerticalAlignment peoperty as it is a subclass of UIControl. You have to set its userInteractionEnabled to NO to prevent user from typing text on it.

I actually noticed that using

<code>sizeToFit</code> does not work in <code>UITableCellView</code>, because the Cells are reused during scrolling.

The solution is to calculate the table cell height according to the font and font size and adjust the label height to it.

As it was quite difficult to find the solution on the web I wrote a <a href="http://hons82.blogspot.com/2012/09/uilabel-change-vertical-alignment.html" rel="nofollow">short post</a> about it

blocks|key|3143346|text|您可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3143347|从IB中设置标签的numberOfLines属性0|ordered-list-item|offset|length|style|CODE|3143348|将标签的lineBreakMode设置为UILineBreakModeWordWrap+(非常重要的)|BOLD|3143349|不管你在标签上放了什么，只需在标签上加上几个@"\n“.前夫-|3143350|[yourTextLabel+setText:@"myLabel\n\n\n\n\n"];|code-block|syntax|javascript|3143351|entityMap^0|0|9|D|0|4|D|K|N|19|5|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@$E|W|F|X|G|H]]|9|@]|A|$]]|$1|I|3|J|5|D|7|Y|8|@$E|Z|F|10|G|H]|$E|11|F|12|G|H]|$E|13|F|14|G|K]]|9|@]|A|$]]|$1|L|3|M|5|6|7|15|8|@]|9|@]|A|$]]|$1|N|3|O|5|P|7|16|8|@]|9|@]|A|$Q|R]]|$1|S|3|-4|5|6|7|17|8|@]|9|@]|A|$]]]|T|$]]

You can do it as follows

<ol>
<li>Set your label's <code>numberOfLines</code> property 0 from IB</li>
<li>Set your label's <code>lineBreakMode</code> as <code>UILineBreakModeWordWrap</code> (very very important)</li>
</ol>

now whatever you set on the label just append few @"\n" to it.....
ex.-

<pre><code>[yourTextLabel setText:@"myLabel\n\n\n\n\n"];
</code></pre>

blocks|key|3143388|text|在iOS+7中，现在不再推荐sizeWithFont:了！一些解决方案，如子类UILabel，必须加以调整。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3143389|我对顶部对齐标签文本的解决方案:在子类TopVerticalAlignmentLabel+:+UILabel中覆盖drawRect:，如下所示：|3143390|-+(void)drawRect:(CGRect)rect

In iOS 7 <code>sizeWithFont:</code> is now deprecated! 
Several solutions like subclassing <code>UILabel</code> have to be adapted.

My solution for top aligned label text:
In a subclass <code>TopVerticalAlignmentLabel : UILabel</code> override <code>drawRect:</code> as follows:

<pre><code>- (void)drawRect:(CGRect)rect
{
 CGRect labelStringRect = [self.text boundingRectWithSize:CGSizeMake(self.frame.size.width, CGFLOAT_MAX)
 options:(NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesFontLeading)
 attributes:@{ NSFontAttributeName: self.font, /* further attributes */}
 context:nil];

 [super drawTextInRect:CGRectMake(0, 0, self.frame.size.width, labelStringRect.size.height)];
}
</code></pre>

blocks|key|3143337|text|我添加了viewDidLoad|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3143338|self.textLabel.numberOfLines+=+0;

make sure your constraints are set correct, so that the label is allowed to shrink or grow. Otherwise it won't work.

Here is the Same Question asked by SomeOne. you'll find more appropriate way to solve this problem.they guys did great explanation over it.

I think so, you should take a look of this.

here in that thread many answers suggest set the dynamic frame for the UILabel on the basis of <code>text</code> as below snippet of code described.

<pre><code> CGSize theStringSize = [textToBeUsed sizeWithFont:lblTitle.font constrainedToSize:labelSize lineBreakMode:lblTitle.lineBreakMode];
 lblTitle.frame = CGRectMake(lblTitle.frame.origin.x, lblTitle.frame.origin.y, theStringSize.width, theStringSize.height);
 lblTitle.text = theText;

 // lblTitle is the Label used for showing the Text.
</code></pre>

you can get more precise idea rather than using <code>textField</code> <a href="https://stackoverflow.com/questions/1054558/vertically-align-text-within-a-uilabel/13287659#13287659">here it is</a>

blocks|key|2786634|text|您可以简单地使用UITextView，并将其UserInteraction设置为“否”，您的所有问题都将得到解决！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2786635|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You can Simply Use A UITextView ,and Set its UserInteraction Enabled to No,And All of your problems will be solved!

In my application I have multiple tableviews with custom cells. Some of the text in the cells are spread out on between 2-4 lines so the height of the label is large enough to contain the content. 

However on iPad the screen is larger and I want the text to appear at the top left point of the label, not in the middle as it do when you use <code>numberOfLines</code> property. I know you can horizontally align the text, but it must be possible to align the text to the top left also? Or is it impossible.

在我的应用程序中，我有多个带有自定义单元格的表视图。单元格中的一些文本分布在2-4行之间，因此标签的高度足以容纳内容。然而，在iPad上，屏幕更大，我希望文本出现在标签的左上角，而不是像使用numberOfLines属性时那样出现在中间。我知道你可以水平对齐文本，但必须有可能使文本与左上角对齐吗？或者是不可能。截图：​​

问是否可以将标签内的文字与“大”框垂直对齐？
