iPhone - UILabel containing text with multiple fonts at the same time

Solution 1:

There is a way to set different / multiple fonts & other properties on Label using NSMutableAttributedString. Foll is my code:

 UIFont *arialFont = [UIFont fontWithName:@"arial" size:18.0];
 NSDictionary *arialDict = [NSDictionary dictionaryWithObject: arialFont forKey:NSFontAttributeName];    
 NSMutableAttributedString *aAttrString = [[NSMutableAttributedString alloc] initWithString:title attributes: arialDict];

 UIFont *VerdanaFont = [UIFont fontWithName:@"verdana" size:12.0];
 NSDictionary *verdanaDict = [NSDictionary dictionaryWithObject:VerdanaFont forKey:NSFontAttributeName];
 NSMutableAttributedString *vAttrString = [[NSMutableAttributedString alloc]initWithString: newsDate attributes:verdanaDict];    
 [vAttrString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:(NSMakeRange(0, 15))];

 [aAttrString appendAttributedString:vAttrString];


 lblText.attributedText = aAttrString;

Note that lblText is the UILabel, outlet as file owner. One can keep on appending as many NSMutableAttributedString he wants..

Also Note that I've added verdana & arial font in my project & added a plist for the same.

Solution 2:

Sorry for late answer. Below code works great for me. I am posting this so that it can be helpful to someone.

    UIFont *font1 = [UIFont fontWithName:kMyriadProSemiBold size:15];
NSDictionary *arialDict = [NSDictionary dictionaryWithObject: font1 forKey:NSFontAttributeName];
NSMutableAttributedString *aAttrString1 = [[NSMutableAttributedString alloc] initWithString:@"My" attributes: arialDict];

UIFont *font2 = [UIFont fontWithName:kMyriadProRegular size:15];
NSDictionary *arialDict2 = [NSDictionary dictionaryWithObject: font2 forKey:NSFontAttributeName];
NSMutableAttributedString *aAttrString2 = [[NSMutableAttributedString alloc] initWithString:@"Profile" attributes: arialDict2];


[aAttrString1 appendAttributedString:aAttrString2];
myProfileLabel.attributedText = aAttrString1;

Please notice that My is semibold and profile is regular. I have used MyRiad font. Thanks

Solution 3:

Use two UILabel IBOutlets, each with a different format (font/color/etc), as you desire.. Move the second one over the first based on where the first one's text ends. You can get that via sizeWithFont:forWidth:lineBreakMode:

Alternatively, you can subclass UILabel, and draw the text yourself in drawRect. If you do it this way, just add an instance variable to tell you how much of the string to draw in one format, and draw the rest in another.

Update: Please see @Akshay's response below. As of iOS6 UILabel's can contain NSMutableAttributedString. When I wrote this, this was not available.

Solution 4:

Update: If you are iOS 6+, then use UILabel.attributedText -- otherwise....

I created this basic UIView subclass to support similar functionality.

The list of things it doesn't support is longer than what it does, but basically it allows you to manage a single line of UILabels and format each as you want. This lets me interject text with a different color in the middle of the line, for instance, and avoid using the heavy-weight UIWebView.

I create these objects by placing a UIView object in my interface (using Interface Builder) and setting the type of the object in IB to MultipartLabel. Then in the code I call updateNumberOfLabels and the various setText selectors as needed.

@implementation MultipartLabel

@synthesize containerView;

 self.containerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)] autorelease];
 [self addSubview:self.containerView];
 self.labels = [NSMutableArray array];

 while (numLabels-- > 0) {
  UILabel * label = [[UILabel alloc] initWithFrame:CGRectZero];
  [self.containerView addSubview:label];
  [self.labels addObject:label];
  [label release];
 }

 [self updateLayout];
}

-(void)setText:(NSString *)text forLabel:(int)labelNum;

 if( [self.labels count] > labelNum && labelNum >= 0 )
 {
  UILabel * thisLabel = [self.labels objectAtIndex:labelNum];
  thisLabel.text = text;

}

-(void)setText:(NSString *)text andFont:(UIFont*)font forLabel:(int)labelNum;

 {
  UILabel * thisLabel = [self.labels objectAtIndex:labelNum];

}

-(void)setText:(NSString *)text andColor:(UIColor*)color forLabel:(int)labelNum;

  thisLabel.textColor = color;
 }

}

- (void)updateLayout {

 int thisX = 0;

 // TODO when it is time to support different sized fonts, need to adjust each y value to line up baselines

 for (UILabel * thisLabel in self.labels) {
  CGSize size = [thisLabel.text sizeWithFont:thisLabel.font
         constrainedToSize:CGSizeMake(9999, 9999)
          lineBreakMode:thisLabel.lineBreakMode];
  CGRect thisFrame = CGRectMake( thisX, 0, size.width, size.height );
  thisLabel.frame = thisFrame;

  thisX += size.width;
 }
}


- (void)dealloc {
 [labels release];
 labels = nil;

 [containerView release];
 containerView = nil;

    [super dealloc];
}

In swift 2.0 this can be done as follows

//Defining fonts of size and type
let firstfont:UIFont = UIFont(name: "Helvetica Neue", size: 17)!
let boldFont:UIFont = UIFont(name: "HelveticaNeue-Bold", size: 17)!
let thirdFont:UIFont = UIFont(name: "HelveticaNeue-ThinItalic", size: 17)!

//Making dictionaries of fonts that will be passed as an attribute        

let firstDict:NSDictionary = NSDictionary(object: firstfont, forKey:  
NSFontAttributeName)
let boldDict:NSDictionary = NSDictionary(object: boldFont, forKey: 
NSFontAttributeName)
let thirdDict:NSDictionary = NSDictionary(object: thirdFont, forKey: 
NSFontAttributeName)

let firstText = "My name is "
let attributedString = NSMutableAttributedString(string: firstText, 
attributes: firstDict as? [String : AnyObject])

let boldText  = "Rajan"
let boldString = NSMutableAttributedString(string:boldText, 
attributes:boldDict as? [String : AnyObject])

let finalText = " iOS"
let finalAttributedString =  NSMutableAttributedString(string: 
finalText, attributes: thirdDict as? [String : AnyObject])

attributedString.appendAttributedString(boldString)
attributedString.appendAttributedString(finalAttributedString)
myLabel.attributedText = attributedString

Edit
Swift 3.0

let firstfont:UIFont = UIFont(name: "Helvetica Neue", size: 17)!
let boldFont:UIFont = UIFont(name: "HelveticaNeue-Bold", size: 17)!
let thirdFont:UIFont = UIFont(name: "HelveticaNeue-ThinItalic", size: 17)!

//Making dictionaries of fonts that will be passed as an attribute

let firstDict:NSDictionary = NSDictionary(object: firstfont, forKey:
        NSFontAttributeName as NSCopying)
let boldDict:NSDictionary = NSDictionary(object: boldFont, forKey:
        NSFontAttributeName as NSCopying)
let thirdDict:NSDictionary = NSDictionary(object: thirdFont, forKey:
        NSFontAttributeName as NSCopying)

let firstText = "My name is "
let attributedString = NSMutableAttributedString(string: firstText,
                                                     attributes: firstDict as? [String : AnyObject])

let boldText  = "Rajan"
let boldString = NSMutableAttributedString(string:boldText,
                                               attributes:boldDict as? [String : AnyObject])

let finalText = " iOS"
let finalAttributedString =  NSMutableAttributedString(string:
        finalText, attributes: thirdDict as? [String : AnyObject])

attributedString.append(boldString)
attributedString.append(finalAttributedString)
myLabel.attributedText = attributedString

Edit
Swift 4.0

let firstfont:UIFont = UIFont(name: "Helvetica Neue", size: 17)!
let boldFont:UIFont = UIFont(name: "HelveticaNeue-Bold", size: 17)!
let thirdFont:UIFont = UIFont(name: "HelveticaNeue-ThinItalic", size: 17)!

//Making dictionaries of fonts that will be passed as an attribute

let firstDict:NSDictionary = NSDictionary(object: firstfont, forKey:
    NSAttributedString.Key.font as NSCopying)
let boldDict:NSDictionary = NSDictionary(object: boldFont, forKey:
    NSAttributedString.Key.font as NSCopying)
let thirdDict:NSDictionary = NSDictionary(object: thirdFont, forKey:
    NSAttributedString.Key.font as NSCopying)

let firstText = "My name is "
let attributedString = NSMutableAttributedString(string: firstText,
                                                         attributes: firstDict as? [NSAttributedString.Key : Any])

let boldText  = "Rajan"
let boldString = NSMutableAttributedString(string:boldText,
                                                   attributes:boldDict as? [NSAttributedString.Key : Any])

let finalText = " iOS"
let finalAttributedString =  NSMutableAttributedString(string:
    finalText, attributes: thirdDict as? [NSAttributedString.Key : Any])

attributedString.append(boldString)
attributedString.append(finalAttributedString)
myLabel.attributedText = attributedString

This will look like
