iphone - 如何使UILabel中的文本缩小字体大小

如果UILabel包含太多文本，如何设置标签以缩小字体大小？

这是我设置UILabel的方法:

     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];

最佳答案

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

以下示例已在iPhone Simulator 3.1.2上进行了测试和验证:

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";
