Alineación del centro del texto atribuido


85

He intentado todo, pero parece que no puedo centrar este texto. ¿Alguien puede decirme dónde está el error?

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]}];

En Swift 5

let paragraph = NSMutableParagraphStyle()
paragraph.alignment = .center
textView.attributedText = NSAttributedString(string: "String",
                                                     attributes: [.paragraphStyle: paragraph])

En 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

En Swift-3

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

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

NSParagraphStyleAttributeName -> NSAttributedStringKey.paragraphStyle

Puede establecer la alineación central usando esto. Recuerde establecer el rango.

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

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

En Swift 4

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

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

De otra manera:

Rápido :

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

Obj-C :

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

En Swift

let titleString = "title here"

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

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

titleAttributedLabel.attributedText = attributedString

Rápido 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

C objetivo

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;

Olvidó agregar el atributo a la cadena en el ejemplo de ObjC :)

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))

Ejemplo

Para hacerlo en Swift 2.x

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

A veces, cuando el texto está en árabe o en otros idiomas de alineación a la derecha, al realizar la alineación Justificado, el texto de la última línea termina en el lado izquierdo. para esto podemos agregar baseWritingDirection a continuación es un código de muestra

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

Establezca el modo de salto de línea, si establece el texto atribuido en UIButton.

Rápido 5

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

C objetivo

NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.alignment = NSTextAlignmentCenter;
style.lineBreakMode = NSLineBreakByClipping;
