如何根据文本长度计算 UILabel 宽度?

问题描述

I want to display an image next to a UILabel, however UILabel has variable text length, so I don't know where to place the image. How can I accomplish this?

解决方案

CGSize expectedLabelSize = [yourString sizeWithFont:yourLabel.font
                        constrainedToSize:maximumLabelSize
                        lineBreakMode:yourLabel.lineBreakMode];

What is -[NSString sizeWithFont:forWidth:lineBreakMode:] good for?

this question might have your answer, it worked for me.

// yourLabel is your UILabel.

float widthIs =
 [self.yourLabel.text
  boundingRectWithSize:self.yourLabel.frame.size
  options:NSStringDrawingUsesLineFragmentOrigin
  attributes:@{ NSFontAttributeName:self.yourLabel.font }
  context:nil]
   .size.width;

NSLog(@"the width of yourLabel is %f", widthIs);
