Spacing text field and center swift-CodePudding

i want to make the text in center and using spacing

but

i used

textfield.defaultTextAttributes.updateValue(32, forKey: NSAttributedString.Key.kern)
textfield.center = containerView.center

and also align center in xib but the text doesn't become center

is there any other solution?

CodePudding user response：

This issue can be resolve by making the text alignment of textField as center.

You can do this in UIKIT or programmatically also

UiKit:

Programmatically:

txtField.textAlignment = .center

CodePudding user response：

When working with text attributes then use:

    let paragraph = NSMutableParagraphStyle()
    paragraph.alignment = .center
    
    let attributes = [NSAttributedString.Key.paragraphStyle:paragraph]
    
    let textfield = UITextField()
    textfield.defaultTextAttributes = attributes

CodePudding user response：

If you want to keep the kern property every time a character is entered, you need to make a calculation for it. Otherwise, the space between characters will work independently of the center property.

override func viewDidLoad() {
    super.viewDidLoad()
    tfff.textAlignment = .center
    tfff.addTarget(self, action: #selector(textDidChange), for: .editingChanged) 

}
@objc func textDidChange(){
    guard let count = tfff.text?.count else {
        return
    }
    let paragraph = NSMutableParagraphStyle()
    paragraph.alignment = .center
 
    if count != 0 {
        let attributedString = NSMutableAttributedString(string: tfff.text!)
        attributedString.addAttributes([NSAttributedString.Key.kern : 32], range: NSRange(location: 0, length: count - 1))
        attributedString.addAttribute(NSAttributedString.Key.paragraphStyle, value: paragraph, range: NSRange(location: 0, length: count - 1))
        tfff.attributedText = attributedString
    }
   
}
