Attributed Text Center Alignment

Question

I have tried everything but cannot seem to center this text. Can someone please tell me where the error is.

NSMutableParagraphStyle *paragraphStyle = NSMutableParagraphStyle.new;
paragraphStyle.alignment = NSTextAlignmentCenter;
label.attributedText = [[NSAttributedString alloc] initWithString:cell.EventTitle.text attributes:@{NSForegroundColorAttributeName : [UIColor whiteColor],NSParagraphStyleAttributeName:paragraphStyle,NSBaselineOffsetAttributeName : @0,NSFontAttributeName : [UIFont fontWithName:@"BrandonGrotesque-Black" size:34]}];

Answer 1

In Swift-4

let paragraph = NSMutableParagraphStyle()
paragraph.alignment = .center

let attributes: [NSAttributedString.Key : Any] = [NSAttributedString.Key.paragraphStyle: paragraph]
let attrString = NSAttributedString(string:"string", attributes: attributes)
textView.attributedText =  attrString

In Swift-3

let paragraph = NSMutableParagraphStyle()
paragraph.alignment = .center

let attributes: [String : Any] = [NSParagraphStyleAttributeName: paragraph]
let attrString = NSAttributedString(string:"string", attributes: attributes)
textView.attributedText =  attrString

Answer 2

You can set the center alignment using this. Remember to set range.

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setAlignment:NSTextAlignmentCenter];

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];
[attributedString addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [string length])];

Answer 3

In Swift 4

let paragraph = NSMutableParagraphStyle()
paragraph.alignment = .center

textView.attributedText = NSAttributedString(string: "string",
                                         attributes: [.paragraphStyle: paragraph])

Answer 4

In Swift

let titleString = "title here"

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .Center

let attributedString = NSAttributedString(
    string: titleString,
    attributes: [NSParagraphStyleAttributeName: paragraphStyle]
)

titleAttributedLabel.attributedText = attributedString

Answer 5

Swift 4+

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = NSTextAlignment.center

// Swift 4.2++
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedString.Key.paragraphStyle:paragraphStyle])

// Swift 4.1--
let attributedString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedStringKey.paragraphStyle:paragraphStyle])

let yourLabel = UILabel()
yourLabel.attributedText = attributedString

Objective-C

NSString *string = @"Your String";
NSMutableParagraphStyle * paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.alignment = NSTextAlignmentCenter;
NSMutableAttributedString * attributedString = [[NSMutableAttributedString alloc] initWithString:string attributes: @{NSParagraphStyleAttributeName:paragraphStyle}];
UILabel *label = [[UILabel alloc] init];
label.attributedText = attributedString;

Answer 6

Another way:

Swift:

let paragraphStyle = NSMutableParagraphStyle.init()
paragraphStyle.alignment = .center
let attributedString = NSAttributedString.init(string: "This will be centered.", attributes: [NSParagraphStyleAttributeName: paragraphStyle])

Obj-C:

NSMutableParagraphStyle *paragraphStyle = [NSMutableParagraphStyle new];
paragraphStyle.alignment = NSTextAlignmentCenter;    
NSAttributedString *attributedString =  [NSAttributedString.alloc initWithString:@"This will be centered." 
attributes: @{NSParagraphStyleAttributeName:paragraphStyle}];

Answer 7

Swift4

let attributedString = NSMutableAttributedString(string: "Example text that is centered using a paragraph style. With the ability to change the width between lines.", attributes: [NSAttributedStringKey.font: GothamFont.medium(with: 14)])

let myParagraphStyle = NSMutableParagraphStyle()
myParagraphStyle.alignment = .center // center the text
myParagraphStyle.lineSpacing = 14 //Change spacing between lines
myParagraphStyle.paragraphSpacing = 38 //Change space between paragraphs
attributedString.addAttributes([.paragraphStyle: myParagraphStyle], range: NSRange(location: 0, length: attributedString.length))

Answer 8

To do it in Swift 2.x

let attributeString = NSMutableAttributedString(string: "text")
style.alignment = .Center
attributeString.addAttribute(NSParagraphStyleAttributeName, value: style, range: range)

Answer 9

Sometimes when text is in Arabic or other right align languages then when doing alignment Justified, last line text ends at left side. for this we can add baseWritingDirection below is sample code

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .justified
paragraphStyle.baseWritingDirection = .rightToLeft
attribute.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:range)
txtView.attributedText = attribute
