Bolding a string using NSMutableAttributedString - ios

Im using the following code to bold a part of string. I want only the Shipment Ref. #: to be bolded. Following is my code
UIFont *boldFont = [UIFont boldSystemFontOfSize:12];
NSString *yourString = [NSString stringWithFormat:#"Shipment Ref. #: %# ",[[[NSUserDefaults alloc] init] valueForKey:#"shipRef"]];
NSRange boldedRange = NSMakeRange(10, 4);
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:yourString];
[attrString beginEditing];
[attrString addAttribute:NSFontAttributeName
value:boldFont
range:boldedRange];
[attrString endEditing];
self.shipRefHeader.text = [attrString mutableString];
The problem is that it is not getting bolded

try this code
NSString * yourString = [NSString stringWithFormat:#"Shipment Ref. #: %# ",[[[NSUserDefaults alloc] init] valueForKey:#"shipRef"]];;
NSMutableAttributedString * attrString = [[NSMutableAttributedString alloc] initWithString:yourString];
NSString *boldString = #"Shipment Ref. #:";
NSRange boldRange = [yourString rangeOfString:boldString];
[attrString addAttribute: NSFontAttributeName value:[UIFont boldSystemFontOfSize:12] range:boldRange];
[self.shipRefHeader setAttributedText: attrString];

How to bold some words in my UITextView using NSMutableAttributedString?

I have a UITextView and there are certain words I'm casting with NSString stringWithFormat that I'd like to be bolded.
I have looked around Stack Overflow and tried to follow the the postings but I guess I'm not understanding it.
Here's what I've been playing around with:
NSRange boldedRange = NSMakeRange(0, 4);
NSString *boldFontName = [[UIFont fontWithName:#"Helvetica-Bold" size:100]fontName];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:self.name];
[attrString beginEditing];
[attrString addAttribute:NSFontAttributeName
value:boldFontName
range:boldedRange];
[attrString endEditing];
self.resultsTextView.attributedText = attrString;
self.resultsTextView.text = [NSString stringWithFormat:#"One day, %# was taking a walk and saw a %# boy. He was %# a %#.", attrString, self.adjective, self.adverb, self.noun];
You can also set it the following way if you want by setting a dictionary as a whole, as attribute
NSString *strTextView = #"This is some demo Text to set BOLD";
NSRange rangeBold = [strTextView rangeOfString:#"BOLD"];
UIFont *fontText = [UIFont boldSystemFontOfSize:10];
NSDictionary *dictBoldText = [NSDictionary dictionaryWithObjectsAndKeys:fontText, NSFontAttributeName, nil];
NSMutableAttributedString *mutAttrTextViewString = [[NSMutableAttributedString alloc] initWithString:strTextView];
[mutAttrTextViewString setAttributes:dictBoldText range:rangeBold];
[textViewTermsPolicy setAttributedText:mutAttrTextViewString];
Use the below code to set Attribute string in TextView.
NSString *infoString =#"I am Kirit Modi from Deesa.";
NSMutableAttributedString *attString=[[NSMutableAttributedString alloc] initWithString:infoString];
UIFont *font_regular=[UIFont fontWithName:#"Helvetica" size:20.0f];
UIFont *font_bold=[UIFont fontWithName:#"Helvetica-Bold" size:20.0f];
[attString addAttribute:NSFontAttributeName value:font_regular range:NSMakeRange(0, 4)];
[attString addAttribute:NSFontAttributeName value:font_bold range:NSMakeRange(5, 15)];
[attString addAttribute:NSFontAttributeName value:font_regular range:NSMakeRange(16, infoString.length - 15 - 1)];
[self.txtView setAttributedText:attString];

I've been using it for over a year and it works great. One limitation: I don't think you can bold multiple times the same string if it appears more than once in your original string. But you can probably expend the code to make it do so if you wish.
If you also need to filter some word from the UITextView and make it underline/change color of that particular text only then you can use the below code.
Here, I'm getting all the doc text in the Content string and filter some particular text that is in Hebrew language.
NSMutableAttributedString *aStr = [[NSMutableAttributedString alloc]initWithString:content attributes:nil];
[aStr addAttribute:NSLinkAttributeName value:#"http://www.apple.com" range:[content rangeOfString:#"מדיניות פרטיות"]];
[aStr addAttribute:NSLinkAttributeName value:#"http://www.google.com" range:[content rangeOfString:#"לינק"]];
textview.linkTextAttributes = #{NSUnderlineStyleAttributeName : #(NSUnderlineStyleSingle)};
textview.delegate = (id)self;
//...You can as per your custom color
[aStr addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:[content rangeOfString:#"מדיניות פרטיות"]];
[aStr addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:[content rangeOfString:#"לינק"]];
//Here You can also add the tap gesture on that text.
//Tap gesture
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(tappedTextView:)];
[textview addGestureRecognizer:tapRecognizer];
[textview setAttributedText:aStr];
textview.textAlignment=NSTextAlignmentRight;
//For getting the text location in the tap gesture
-(void)tappedTextView:(UITapGestureRecognizer *)tapGesture
{
UITextView *textView = (UITextView *)tapGesture.view;
CGPoint tapLocation = [tapGesture locationInView:textView];
UITextPosition *textPosition = [textView closestPositionToPoint:tapLocation];
NSDictionary *attributes = [textView textStylingAtPosition:textPosition inDirection:UITextStorageDirectionForward];
NSString *urlStr = attributes[NSLinkAttributeName];
if (urlStr)
{
//[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#",url]]];
PrivacyViewController *next = [PrivacyViewController new];
[self.navigationController pushViewController:next animated:YES];
}
}

trying to make dynamic NSString texts into bold text

I'm new to iOS Development..I cannot get my strings to get BOLD.
Thanks in advance!
Here's my code
- (void)viewDidLoad {
[super viewDidLoad];
NSString *sentence = [[NSString alloc] initWithString:[NSString stringWithFormat:#"%#%#%#%#", self.name, self.adjective, self.noun, self.verb]];
NSMutableAttributedString *finalSentence = [[NSMutableAttributedString alloc] initWithString:sentence];
NSRange nameRange = NSMakeRange(0, self.name.length);
NSRange adjectiveRange = NSMakeRange(self.name.length, self.adjective.length);
NSRange nounRange = NSMakeRange((self.adjective.length + self.name.length), self.noun.length);
NSRange verbRange = NSMakeRange((self.adjective.length + self.name.length + self.noun.length), self.verb.length);
[finalSentence beginEditing];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Arial-BoldMT" size:17.0] range:nameRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Arial-BoldMT" size:17.0] range:adjectiveRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica-Bold" size:12.0] range:nounRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica-Bold" size:12.0] range:verbRange];
[finalSentence endEditing];
NSString *completeSentence = [finalSentence string];
self.resultTextView.text = completeSentence;
}
It's not an accident that there's a separate NSAttributedString class. The completeSentence, that you retrieve using your attributed string's string property, is a plain NSString, does not contain formatting info (because it cannot).
You have to assign the attributed string object itself to the attributedText property of your text view.
You are assigning the plain text version of your attributed text ([finalSentence string]) to the plain text property of your UITextView.
You should set the attributed text directly to the attributedText property of the UITextView -
self.resultTextView.attributedText=finalSentence
Just call
self.resultTextView.attributedText = finalSentence;
Here is code that you need
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *sentence = [[NSString alloc] initWithString:[NSString stringWithFormat:#"%#%#%#%#", self.name, self.adjective, self.noun, self.verb]];
NSMutableAttributedString *finalSentence = [[NSMutableAttributedString alloc] initWithString:sentence];
NSRange nameRange = NSMakeRange(0, self.name.length);
NSRange adjectiveRange = NSMakeRange(self.name.length, self.adjective.length);
NSRange nounRange = NSMakeRange((self.adjective.length + self.name.length), self.noun.length);
NSRange verbRange = NSMakeRange((self.adjective.length + self.name.length + self.noun.length), self.verb.length);
[finalSentence beginEditing];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Arial-BoldMT" size:17.0] range:nameRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Arial-BoldMT" size:17.0] range:adjectiveRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica-Bold" size:12.0] range:nounRange];
[finalSentence addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica-Bold" size:12.0] range:verbRange];
[finalSentence endEditing];
self.resultTextView.attributedText = finalSentence;
}

Bold a part of title, iOS 7

I have read several method about bolding a part of string.
But I still can't get it work.
Here's my code
#define FONT_OPEN_BOLD(s) [UIFont fontWithName:#"OpenSans-Bold" size:s]
In viewDidLoad function
NSString *stringName = #"ShowTimes" ;
UIFont *font = FONT_OPEN_BOLD(15.0f);
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:stringName];
[attrString addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, 4)];
self.title = stringName;
Any suggestion?
Thank you in advance. ^^
NSString *stringName = #"ShowTimes" ;
UIFont *font = FONT_OPEN_BOLD(15.0f);
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:stringName];
[attrString addAttribute:NSFontAttributeName value:font range:NSMakeRange(0, 4)];
//Initialize TTAttributedLabel with rect
UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 20, 150)];
//Set the attributedText property of TTAttributedLabel
label.attributedText = attrString;
//Set navigationItem.titleView to the label view we've created
self.navigationItem.titleView = label;
What you could do is use an NSAttributedString.
NSString *boldFontName = [[UIFont boldSystemFontOfSize:12] fontName];
NSString *yourString = ...;
NSRange boldedRange = NSMakeRange(22, 4);
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:yourString];
[attrString beginEditing];
[attrString addAttribute:kCTFontAttributeName
value:boldFontName
range:boldedRange];
[attrString endEditing];
//draw attrString here...
Take a look at this handy dandy guide to drawing NSAttributedString objects with Core Text.

UIRefreshControl attributedTitle multiple lines

Is it possible to use multiple lines in the UIRefreshControl title? Whenever I add \n to the NSAttributedString only the first line will be displayed. I'm trying to set a title and on the next line some more text. So is there a workaround to use two lines of text in the UIRefreshControl?
This is the current code where only "Title Here" is displayed:
self.refreshControl = [[UIRefreshControl alloc] init];
NSString *title = #"Title Here";
NSString *subText = #"Subtext Here";
NSMutableAttributedString *attString=[[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:#"%#\n%#",title,subText]];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica" size:20.0f] range:NSMakeRange(0, [title length])];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica" size:14.0f] range:NSMakeRange([title length],[subText length])];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, [title length])];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor lightGrayColor] range:NSMakeRange([title length], [subText length])];
self.refreshControl.attributedTitle = attString;
here is a tricky method: find the UILabel in the UIRefreshControl and set numberOfLines = 0.
UILabel *titleLabel = [[[[self.refreshControl subviews] firstObject] subviews] lastObject];
if (titleLabel) {
titleLabel.numberOfLines = 0;
NSString title = #"Pull to Refresh.\nUpdated Time: 09:30"; // \n for new line.
self.refreshControl.attributedTitle = [[NSAttributedString alloc] initWithString:title];
}
This piece of code will work
NSString *title = #"Title Here";
NSString *subText = #"Subtext Here";
NSMutableAttributedString *titleAttString = [[NSMutableAttributedString alloc] initWithString:title];
NSMutableAttributedString *subTitleAttString = [[NSMutableAttributedString alloc] initWithString:subText];
[titleAttString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica" size:20.0f] range:NSMakeRange(0, [title length])];
[subTitleAttString addAttribute:NSFontAttributeName value:[UIFont fontWithName:#"Helvetica" size:14.0f] range:NSMakeRange(0,[subTitle length])];
[titleAttString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, [title length])];
[subTitleAttString addAttribute:NSForegroundColorAttributeName value:[UIColor lightGrayColor] range:NSMakeRange(0, [subTitle length])];
[titleAttString appendAttributedString:subTitleAttString];
self.refreshControl.attributedTitle = titleAttString;
The trick is to change the UILable's property of Refresh Controller to Zero.
The hack is we have to find the label through the subviews and there child as shown below.
Here is a Swift version
if let refreshLabel = refreshControl?.subviews.first?.subviews.last as? UILabel {
refreshLabel.numberOfLines = 0
}
So here is the full code sample
private var marketRefreshController = UIRefreshControl()
private var lastUpdatedDate = Date()
override func viewDidLoad() {
super.viewDidLoad()
tableView.refreshControl = marketRefreshController
if let refreshLabel = refreshControl?.subviews.first?.subviews.last as? UILabel {
refreshLabel.numberOfLines = 0
}
marketRefreshController.addTarget(self, action: #selector(refreshMarketData), for: .valueChanged)
marketRefreshController.tintColor = UIColor.blue
let textAttributes = [NSAttributedString.Key.font: UIFont.appSubTitle,
NSAttributedString.Key.foregroundColor: UIColor.blue]
let timeSinceLastUpdate = lastUpdatedDate.timeAgoSinceNow // Date Sting Converter Helper Method
let displayString = "Fetching Market Data ... \n Last Updated: \(timeSinceLastUpdate)"
marketRefreshController.attributedTitle = NSAttributedString(string: displayString,
attributes: textAttributes)
tableView.addSubview(marketRefreshController)
}
The expected output should be like -

Can I set the `attributedText` property of `UILabel`

Can I set the attributedText property of a UILabel object? I tried the below code:
UILabel *label = [[UILabel alloc] init];
label.attributedText = #"asdf";
But it gives this error:
Property "attributedText" not found on object of type 'UILabel *'
#import <CoreText/CoreText.h> not working
Here is a complete example of how to use an attributed text on a label:
NSString *redText = #"red text";
NSString *greenText = #"green text";
NSString *purpleBoldText = #"purple bold text";
NSString *text = [NSString stringWithFormat:#"Here are %#, %# and %#",
redText,
greenText,
purpleBoldText];
// If attributed text is supported (iOS6+)
if ([self.label respondsToSelector:#selector(setAttributedText:)]) {
// Define general attributes for the entire text
NSDictionary *attribs = #{
NSForegroundColorAttributeName: self.label.textColor,
NSFontAttributeName: self.label.font
};
NSMutableAttributedString *attributedText =
[[NSMutableAttributedString alloc] initWithString:text
attributes:attribs];
// Red text attributes
UIColor *redColor = [UIColor redColor];
NSRange redTextRange = [text rangeOfString:redText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:redColor}
range:redTextRange];
// Green text attributes
UIColor *greenColor = [UIColor greenColor];
NSRange greenTextRange = [text rangeOfString:greenText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:greenColor}
range:greenTextRange];
// Purple and bold text attributes
UIColor *purpleColor = [UIColor purpleColor];
UIFont *boldFont = [UIFont boldSystemFontOfSize:self.label.font.pointSize];
NSRange purpleBoldTextRange = [text rangeOfString:purpleBoldText];// * Notice that usage of rangeOfString in this case may cause some bugs - I use it here only for demonstration
[attributedText setAttributes:#{NSForegroundColorAttributeName:purpleColor,
NSFontAttributeName:boldFont}
range:purpleBoldTextRange];
self.label.attributedText = attributedText;
}
// If attributed text is NOT supported (iOS5-)
else {
self.label.text = text;
}
Unfortunately, UILabel doesn't support attributed strings. You can use OHAttributedLabel instead.
Update: Since iOS6, UILabel does support attributed strings. See UILabel reference or Michael Kessler's answer below for more details.
NSString *str1 = #"Hi Hello, this is plain text in red";
NSString *cardName = #"This is bold text in blue";
NSString *text = [NSString stringWithFormat:#"%#\n%#",str1,cardName];
// Define general attributes for the entire text
NSDictionary *attribs = #{
NSForegroundColorAttributeName:[UIColor redColor],
NSFontAttributeName: [UIFont fontWithName:#"Helvetica" size:12]
};
NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:text attributes:attribs];
UIFont *boldFont = [UIFont fontWithName:#"Helvetica-Bold" size:14.0];
NSRange range = [text rangeOfString:cardName];
[attributedText setAttributes:#{NSForegroundColorAttributeName: [UIColor blueColor],
NSFontAttributeName:boldFont} range:range];
myLabel = [[UILabel alloc] initWithFrame:CGRectZero];
myLabel.attributedText = attributedText;
for Swift 4:
iOS 11 and xcode 9.4
let str = "This is a string which will shortly be modified into AtrributedString"
var attStr = NSMutableAttributedString.init(string: str)
attStr.addAttribute(.font,
value: UIFont.init(name: "AppleSDGothicNeo-Bold", size: 15) ?? "font not found",
range: NSRange.init(location: 0, length: str.count))
self.textLabel.attributedText = attStr
For people using swift, here's a one-liner:
myLabel.attributedText = NSMutableAttributedString(string: myLabel.text!, attributes: [NSFontAttributeName:UIFont(name: "YourFont", size: 12), NSForegroundColorAttributeName: UIColor.whiteColor()])
so,here is the code to have different properties for sub strings ,of a string.
NSString *str=#"10 people likes this";
NSString *str2=#"likes this";
if ([str hasSuffix:str2])
{
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:str];
// for string 1 //
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(0,str.length-str2.length)];
[string addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:14] range:NSMakeRange(0,str.length-str2.length)];
// for string 2 //
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange((str.length-str2.length),str2.length)];
[string addAttribute:NSFontAttributeName value:[UIFont italicSystemFontOfSize:12] range:NSMakeRange((str.length-str2.length),str2.length)];
label.attributedText=string;
}
else
{
label.text =str;
}
Hope this helps ;)
NSMutableAttributedString* attrStr = [NSMutableAttributedString attributedStringWithString:#"asdf"];
[attrStr setFont:[UIFont systemFontOfSize:12]];
[attrStr setTextColor:[UIColor grayColor]];
[attrStr setTextColor:[UIColor redColor] range:NSMakeRange(0,5)];
lbl.attributedText = attrStr;
UIFont *font = [UIFont boldSystemFontOfSize:12];
NSDictionary *fontDict = [NSDictionary dictionaryWithObject: font forKey:NSFontAttributeName];
NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:#" v 1.2.55" attributes: fontDict];
UIFont *fontNew = [UIFont boldSystemFontOfSize:17];
NSDictionary *fontDictNew = [NSDictionary dictionaryWithObject: fontNew forKey:NSFontAttributeName];
NSMutableAttributedString *attrStringNew = [[NSMutableAttributedString alloc] initWithString:#“Application” attributes: fontDictNew];
[attrStringNew appendAttributedString: attrString];
self.vsersionLabel.attributedText = attrStringNew;
