如何以减少的字体大小制作文本 UILabel

descriptionLabel.adjustsFontSizeToFitWidth = YES;

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

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";

+ /void/resizeFontForLabel:/UILabel*/aLabel maxSize:/int/maxSize minSize:/int/minSize { 

 // use font from provided label so we don't lose color, style, etc

 UIFont *font = aLabel.font;



 // start with maxSize and keep reducing until it doesn't clip

 for/int i = maxSize; i >= minSize; i--/ {

 font = [font fontWithSize:i];

 CGSize constraintSize = CGSizeMake/aLabel.frame.size.width, MAXFLOAT/;



 // This step checks how tall the label would be with the desired font.

 CGSize labelSize = [aLabel.text sizeWithFont:font constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

 if/labelSize.height <= aLabel.frame.size.height/

 break;

 }

 // Set the UILabel's font to the newly adjusted font.

 aLabel.font = font;

}

adjustsFontSizeToFitWidth

if/labelSize.height <= aLabel.frame.size.height/

{

 aLabel.numberOfLines = labelSize.height / font.lineHeight;



 break;
