In UILabel, there is an adjustsFontSizeToFitWidth property which will automatically adjust the text font size to fit the UILabel width.
UILabel *aLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 20.0)]; aLabel.adjustsFontSizetoWidth = YES; // This is a must aLabel.minimumFontSize = 8.0f; aLabel.numberOfLines = 1; // This is a must too =.=
But this only work for numberOfLines = 1…
Luckily, i found a workaround from a blog post. Here comes to the solution.
// Initialize the Label, Text and Font UILabel *aLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 64.0, 320.0, 60.0)]; UIFont *aFont = [UIFont fontWithName:@"Helvetica" size:28.0]; NSString *aText = @"And I will love you, baby - Always. And I'll be there forever and a day - Always. I'll be there till the stars don't shine. Till the heavens burst and the words don't rhyme. And I know when I die, you'll be on my mind. And I'll love you - Always."; // Logic for adjusting the size for (NSInteger i = 28; i > 8; i--) { aFont = [aFont fontWithSize:i]; // Limit the width to UILabel width CGSize constraintSize = CGSizeMake(320.0f, MAXFLOAT); CGSize labelSize = [aText sizeWithFont:aFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap]; // Break the loop when text height < UILabel height if (labelSize.height <= 60.0f) { break; } } // Set the font and text for UILabel aLabel.font = aFont; aLabel.text = aText; aLabel.numberOfLines = 4; // Add the Label to the view and release it [self.view addSubview:aLabel]; [aLabel release];
Done =)
