NSMutableParagraphStyle *paragraphStyle = NSMutableParagraphStyle.new;
paragraphStyle.alignment = NSTextAlignmentCenter;
NSAttributedString *attributedString =
[NSAttributedString.alloc initWithString:@"someText"
attributes:
@{NSParagraphStyleAttributeName:paragraphStyle}];
Swift 4.2
let paragraphStyle: NSMutableParagraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.center
let attributedString = NSAttributedString(string: "someText", attributes: [NSAttributedString.Key.paragraphStyle : paragraphStyle])
I was searching for the same issue and was able to center align the text in a NSAttributedString this way:
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init] ;
[paragraphStyle setAlignment:NSTextAlignmentCenter];
NSMutableAttributedString *attribString = [[NSMutableAttributedString alloc]initWithString:string];
[attribString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [string length])];
let titleParagraphStyle = NSMutableParagraphStyle()
titleParagraphStyle.alignment = .center
let titleFont = UIFont.preferredFont(forTextStyle: UIFontTextStyle.headline)
let title = NSMutableAttributedString(string: "You Are Registered",
attributes: [.font: titleFont,
.foregroundColor: UIColor.red,
.paragraphStyle: titleParagraphStyle])
let titleParagraphStyle = NSMutableParagraphStyle()
titleParagraphStyle.alignment = .center
let titleFont = UIFont.preferredFont(forTextStyle: UIFontTextStyle.headline)
let title = NSMutableAttributedString(string: "You Are Registered",
attributes: [NSFontAttributeName:titleFont,
NSForegroundColorAttributeName:UIColor.red,
NSParagraphStyleAttributeName: titleParagraphStyle])
(original answer below)
let titleParagraphStyle = NSMutableParagraphStyle()
titleParagraphStyle.alignment = .Center
let titleFont = UIFont.preferredFontForTextStyle(UIFontTextStyleHeadline)
let title = NSMutableAttributedString(string: "You Are Registered",
attributes:[NSFontAttributeName:titleFont,
NSForegroundColorAttributeName:UIColor.redColor(),
NSParagraphStyleAttributeName: titleParagraphStyle])
As NSAttributedString
is primarily used with Core Text on iOS, you have to use CTParagraphStyle
instead of NSParagraphStyle
. There is no mutable variant.
For example:
CTTextAlignment alignment = kCTCenterTextAlignment;
CTParagraphStyleSetting alignmentSetting;
alignmentSetting.spec = kCTParagraphStyleSpecifierAlignment;
alignmentSetting.valueSize = sizeof(CTTextAlignment);
alignmentSetting.value = &alignment;
CTParagraphStyleSetting settings[1] = {alignmentSetting};
size_t settingsCount = 1;
CTParagraphStyleRef paragraphRef = CTParagraphStyleCreate(settings, settingsCount);
NSDictionary *attributes = @{(__bridge id)kCTParagraphStyleAttributeName : (__bridge id)paragraphRef};
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:@"Hello World" attributes:attributes];
Swift 4 answer:
// Define paragraph style - you got to pass it along to NSAttributedString constructor
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center
// Define attributed string attributes
let attributes = [NSAttributedStringKey.paragraphStyle: paragraphStyle]
let attributedString = NSAttributedString(string:"Test", attributes: attributes)
