UIButton标题对齐和多行支持

Question

如何将UIButton的标题设置为左对齐，以及如何在UIButton显示多行文本？

Answer 1

这也是在代码中进行UIButton对齐的代码：-

[myButton setContentHorizontalAlignment:UIControlContentHorizontalAlignmentLeft];

Answer 2

To set the alignment of a UIButton , look in the Attributes Inspector in Interface Builder for the button. There's a section called Alignment. Set it to left. Or right, or whatever you want.

To do it in code, use the contentHorizontalAlignment property of UIControl . You can set it to any of these properties:

UIControlContentHorizontalAlignmentCenter
UIControlContentHorizontalAlignmentLeft
UIControlContentHorizontalAlignmentRight
UIControlContentHorizontalAlignmentFill

[myButton setContentHorizontalAlignment:UIControlContentHorizontalAlignmentRight];

None of these options look particularly good (as you can see above), and you might have might have more luck using the contentEdgeInsets property of UIButton to reposition the content.

To set a multiline title on a UIButton , check this forum post which describes changing the button label.

Or you can use this code to quickly make a 2 line button:

myButton.titleLabel.textAlignment = UITextAlignmentCenter;
myButton.titleLabel.lineBreakMode = UILineBreakModeCharacterWrap;
[myButton setTitle:@"Siegfried\nRoy" forState:UIControlStateNormal];

Raju, don't forget to mark questions as accepted.

Answer 3

Actually, you can set the lineBreakMode to UILineBreakModeWordWrap or UILineBreakModeCharacterWrap . This breaks the text into multiple lines if necessary.

Answer 4

Try this

    myButton.titleLabel.textAlignment = UITextAlignmentLeft;
    myButton.titleLabel.lineBreakMode = UILineBreakModeCharacterWrap;
    myButton.titleLabel.numberOfLines = 0;

Answer 5

To add a Paragraph effect you can change the size of title.
