推荐答案

下面是这样做的两种方式...

Here are two ways of doing that...

1 第一套 numberOfLines 0，然后使用 sizeToFit 属性的UILabel 让你的的UILabel 显示屏以其 contentSize 。

1. First set numberOfLines to 0 and then use sizeToFit property of UILabel so your UILabel display with its contentSize.

yourLabel.numberOfLines = 0;

[yourLabel sizeToFit];

2 另一种选择是采取的UITextField ，而不是的UILabel ，并设定< $ C C> userInteractionEnabled $以 NO 象下面...

2. Another option is to take UITextField instead of UILabel and set userInteractionEnabled to NO like below...

[yourTextField setUserInteractionEnabled:NO];

然后设置 contentVerticalAlignment 属性底部像下面......

and then set the contentVerticalAlignment property to bottom like below....

[yourTextField setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];

更新

此外，与的UITextField ，我们无法实现多行。因此，而不是我们可以使用的UITextView ，并设置其 userInteractionEnabled 到 NO 。然后，使用下面的code，使其底部对齐。

Also, with UITextField, we can't achieve multiple lines. So instead we can use UITextView and set its userInteractionEnabled to NO. Then, use the code below to make it bottom aligned.

CGFloat topCorrect = ([label bounds].size.height - [label contentSize].height);
topCorrect = (topCorrect <0.0 ? 0.0 : topCorrect);
label.contentOffset = (CGPoint){.x = 0, .y = -topCorrect};
