iOS: How to tell if UILabel's font has been auto-resized?

Question

有没有办法以编程方式确定标签中的文本是否已自动调整大小？

Answer 1

You could probably check the size of the text with the font and compare it to the label's width.

Maybe something like this:

CGSize size = [yourLabel.text sizeWithFont:label.font constrainedToSize:CGSizeMake(100000, yourLabel.frame.size.height)  lineBreakMode:yourLabel.lineBreakMode];

if(size.width > label.frame.size.width)
{
    //you are being autosized
}
