Is it possible to use the autoshrink property in conjunction on multiple lines on a UILabel
? for example, the large text size possible on 2 available lines.
I modified the above code somewhat to make it a category on UILabel
:
Header file:
#import <UIKit/UIKit.h>
@interface UILabel (MultiLineAutoSize)
- (void)adjustFontSizeToFit;
@end
And the implementation file:
@implementation UILabel (MultiLineAutoSize)
- (void)adjustFontSizeToFit
{
UIFont *font = self.font;
CGSize size = self.frame.size;
for (CGFloat maxSize = self.font.pointSize; maxSize >= self.minimumFontSize; maxSize -= 1.f)
{
font = [font fontWithSize:maxSize];
CGSize constraintSize = CGSizeMake(size.width, MAXFLOAT);
CGSize labelSize = [self.text sizeWithFont:font constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];
if(labelSize.height <= size.height)
{
self.font = font;
[self setNeedsLayout];
break;
}
}
// set the font to the minimum size anyway
self.font = font;
[self setNeedsLayout];
}
@end
