我如何使文本在UILabel收缩字体大小 [英] How can I make text in a UILabel shrink font size

问题描述

如果UILabel包含太多文本，我该如何设置我的标签以缩小字体大小？

If a UILabel contains too much text, how can I setup my label so that it shrinks font-sizes?

这是我设置UILabel的方法：

Here is how I am setting up my UILabel:

     descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(200, 30, 130, 150)];
    [descriptionLabel setFont:[Utils getSystemFontWithSize:14]];
    [descriptionLabel setBackgroundColor:[UIColor clearColor]];
    [descriptionLabel setTextColor:[UIColor whiteColor]];
    descriptionLabel.numberOfLines = 1;
    [self addSubview:descriptionLabel];

推荐答案

descriptionLabel.adjustsFontSizeToFitWidth = YES;
descriptionLabel.minimumFontSize = 10.0; //adjust to preference obviously

以下示例在iPhone Simulator 3.1.2上测试和验证： / p>

The following example is tested and verified on iPhone Simulator 3.1.2:

UILabel *descriptionLabel = [[UILabel alloc] initWithFrame:CGRectMake(90, 0, 200, 30)];

descriptionLabel.font = [UIFont systemFontOfSize:14.0];
descriptionLabel.minimumFontSize = 10.0;
descriptionLabel.adjustsFontSizeToFitWidth = YES;
descriptionLabel.numberOfLines = 1;
descriptionLabel.text = @"supercalifragilisticexpialidocious even thought he sound of it is something quite attrocious";
