In my application I am displaying a text in my label like this
cell.lblUserDetails.text=[NSString stringWithFormat:#"%# and %# other likes your post", [dictionary valueForKey:#"username"], [dictionary valueForKey:#"CuriousCount"]];
Here I want to highlight Username and CuriousCount (in red color) and also username and CuriousCount should be clickable.
UIColor *color = [UIColor redColor];
NSDictionary *attrs = #{ NSForegroundColorAttributeName : color };
NSAttributedString *nameStr = [[NSAttributedString alloc] initWithString:[dictionary valueForKey:#"username"] attributes:attrs];
NSAttributedString *countStr = [[NSAttributedString alloc] initWithString:[dictionary valueForKey:#"CuriousCount"] attributes:attrs];
NSMutableAttributedString *string = [[NSMutableAttributedString alloc] init];
[string appendAttributedString:nameStr];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:#" and "]];
[string appendAttributedString:countStr];
[string appendAttributedString:[[NSAttributedString alloc] initWithString:#" other likes your post"]];
cell.lblUserDetails.attributedText = string;

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];
My code to justify label text is given below:-
-(void)justifyToLabel:(UILabel*)label withStr:(NSString*)str{
NSMutableParagraphStyle *paragraphStyles = [[NSMutableParagraphStyle alloc] init];
paragraphStyles.alignment = NSTextAlignmentJustified;
NSDictionary *attributes = #{NSParagraphStyleAttributeName: paragraphStyles};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString: str attributes: attributes];
label.attributedText = attributedString;
}
I don't know that why its not working. Please give a best solution.
Thanks
Try the below code:
You have not assigned any value to firstLineHeadIndent property, that's why it is not working.
NSMutableParagraphStyle *paragraphStyles = [[NSMutableParagraphStyle alloc] init];
paragraphStyles.alignment = NSTextAlignmentJustified; //justified text
paragraphStyles.firstLineHeadIndent = 1.0; //must have a value to make it work
NSDictionary *attributes = #{NSParagraphStyleAttributeName: paragraphStyles};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString: string attributes: attributes];
label.attributedText = attributedString;
Is there any support for spannable string in iOS?
I would like to create an underlineSpan and on click of it and then open some other view controller.
NSAttributedString *title;
title = [[NSAttributedString alloc] initWithString:#"hello how r u..." attributes:#{ NSFontAttributeName : [UIFont fontWithName:#"Noteworthy-Bold" size:15], NSUnderlineStyleAttributeName : #1 , NSStrokeColorAttributeName : [UIColor blackColor]}]; //1
UILabel *label;
label = [[UILabel alloc] initWithFrame:CGRectMake( (self.view.bounds.size.width - title.size.width) / 2.0f, 40.0f, title.size.width, title.size.height)]; //2
label.attributedText = title; //3
[self.view addSubview:label];
Yes, they are called NSAttributedStrings in iOS.
Example Code to Add underline
NSString *str = #"Amit";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:str];
[attributedString addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInt:NSUnderlineStyleSingle] range:NSMakeRange(0, 4)];
More info # Apple Documentation
To add link to that underline you check out this code:
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:#"Google Webpage"];
[attributedString addAttribute:NSLinkAttributeName
value:#"http://www.google.com"
range:[[attributedString string] rangeOfString:#"Google Webpage"]];
NSDictionary *linkAttributes = #{NSForegroundColorAttributeName: [UIColor greenColor],
NSUnderlineColorAttributeName: [UIColor lightGrayColor],
NSUnderlineStyleAttributeName: #(NSUnderlinePatternSolid)};
// assume that textView is a UITextView previously created (either by code or Interface Builder)
textView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;
textView.delegate = self;

I have builed a button with two titles line by this code:
rootBntUI.titleLabel.font = [UIFont fontWithName:#"Avenir-Black" size:UserListFontSize];
[rootBntUI.layer setBorderWidth:0];
rootBntUI.titleLabel.textColor = [UIColor whiteColor];
rootBntUI.titleLabel.lineBreakMode = NSLineBreakByTruncatingTail;
rootBntUI.titleLabel.textAlignment = NSTextAlignmentCenter;
rootBntUI.titleLabel.numberOfLines = 2;
Everything is working fine but how can I control line spacing of button title?
You can do the styling from the xib . Use button title attributed in attribute inspector and you can set all the styling parameter along with spacing .
I have resolved my problem, and this solution for anyone who have similar question.
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
[style setAlignment:NSTextAlignmentCenter];
[style setLineBreakMode:NSLineBreakByWordWrapping];
[style setLineSpacing:-50];
UIFont *font1 = [UIFont fontWithName:#"Avenir-Black" size:UserListFontSize];
NSDictionary *dict1 = #{NSUnderlineStyleAttributeName:#(NSUnderlineStyleSingle),
NSFontAttributeName:font1,
NSParagraphStyleAttributeName:style};
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] init];
[attString appendAttributedString:[[NSAttributedString alloc] initWithString:[NSString stringWithFormat:#"%#", obj] attributes:dict1]];
[FriendBnt setAttributedTitle:attString forState:UIControlStateNormal];
[[FriendBnt titleLabel] setNumberOfLines:0];
[[FriendBnt titleLabel] setLineBreakMode:NSLineBreakByWordWrapping];
Happy coding.
This works in Swift 2 using .lineHeightMultiple to compress the title text on a button.
let style = NSMutableParagraphStyle()
style.lineHeightMultiple = 0.8
style.alignment = .Center
style.lineBreakMode = .ByWordWrapping
let dict1:[String:AnyObject] = [
NSParagraphStyleAttributeName: style,
NSUnderlineStyleAttributeName: NSUnderlineStyle.StyleSingle.rawValue
]
let attrString = NSMutableAttributedString()
attrString.appendAttributedString(NSAttributedString(string: "Button Text here over two lines", attributes: dict1))
myButton.setAttributedTitle(attrString, forState: .Normal)
myButton.titleLabel?.numberOfLines = 0
What really worked for me to change line height of the UIButton title label, was this:
NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
style.maximumLineHeight = 12.0;
style.minimumLineHeight = 12.0;
UIColor *colorO = [UIColor whiteColor];
UIColor *colorD = [UIColor redColor];
NSDictionary *firstAttributes = #{NSFontAttributeName : [UIFont fontWithName:#"HelveticaNeue-CondensedBold" size:getFloatScaledFactor(13.0)],
NSForegroundColorAttributeName : colorO,
NSParagraphStyleAttributeName:style
};
NSDictionary *secondAttributes = #{NSFontAttributeName : [UIFont fontWithName:#"HelveticaNeue-CondensedBold" size:getFloatScaledFactor(13.0)],
NSForegroundColorAttributeName : colorD,
NSParagraphStyleAttributeName:style
};
NSArray *textArray = [title componentsSeparatedByString:#"\n"];
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] init];
[attString appendAttributedString:[[NSAttributedString alloc] initWithString:[NSString stringWithFormat:#"%#", textArray[0]] attributes:firstAttributes]];
[attString appendAttributedString:[[NSAttributedString alloc] initWithString:[NSString stringWithFormat:#"%#", textArray[1]] attributes:secondAttributes]];
[self.btnRight setAttributedTitle:attString forState:UIControlStateNormal];
As a alternative solution.
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...
