Attributed Text Center Alignment

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]}];

helper method based on the helpful answers above

public extension NSAttributedString
{
    var centered: NSAttributedString
    {
        let paragraph = NSMutableParagraphStyle()
        paragraph.alignment = .center
        let m = NSMutableAttributedString(attributedString: self)
        m.addAttribute(.paragraphStyle, value: paragraph, range: NSMakeRange(0, length))
        return m
    }
}

in case you want the Is dotted and Ts crossed el verbositas version

var centered: NSAttributedString {
        let paragraphStyle: NSMutableParagraphStyle = NSMutableParagraphStyle()
            paragraphStyle.alignment = NSTextAlignment.center

        let attributedString = NSMutableAttributedString(attributedString: self)
        attributedString.addAttributes([NSAttributedString.Key.paragraphStyle : paragraphStyle],
                                       range: NSRange(location: 0, length: attributedString.length))
        return attributedString
}

Another way:

Swift:

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}];

Set line breakmode, if you set attributed text on UIButton.

Swift 5

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

Objective-C

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

In Swift 5

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

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

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

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;

To do it in Swift 2.x

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

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])];
