I found the Answer by struggling few days. And it is quite easy.
guard
let font1 = UIFont(name: "HelveticaNeue-Bold", size: 22),
let font2 = UIFont(name: "HelveticaNeue-Medium", size: 22) else { return }
let dict1:[String:Any] = [
// NSUnderlineStyleAttributeName:NSUnderlineStyle.styleSingle.rawValue,
NSFontAttributeName:font2,
NSParagraphStyleAttributeName:style,
NSForegroundColorAttributeName: UIColor.white
]
let dict2:[String:Any] = [
// NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
NSFontAttributeName:font1,
NSParagraphStyleAttributeName:style,
NSForegroundColorAttributeName: UIColor.white,
// NSFontAttributeName: UIFont.boldSystemFont(ofSize: 20)
]
let dict3:[String:Any] = [
// NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
NSFontAttributeName:font2,
NSParagraphStyleAttributeName:style,
NSForegroundColorAttributeName: UIColor.white
]
let dict4:[String:Any] = [
// NSUnderlineStyleAttributeName:NSUnderlineStyle.styleNone.rawValue,
NSFontAttributeName:font1,
NSParagraphStyleAttributeName:style,
NSForegroundColorAttributeName: UIColor.white
]
let attString = NSMutableAttributedString()
attString.append(NSAttributedString(string: "Call to", attributes: dict1))
attString.append(NSAttributedString(string: " 2222555 ", attributes: dict2))
attString.append(NSAttributedString(string: " To Book Your Skip ", attributes: dict3))
attString.append(NSAttributedString(string: "NOW", attributes: dict4))
btnCall.setAttributedTitle(attString, for: .normal)
And its Working perfectly as expected.

My requirement is such that when placeholder of textfield is visible then its color should be gray and font size 10, but when user starts typing into the textfield, its color should be black and font size 14. I have tried this:
textField.attributedPlaceholder = NSAttributedString(string: placeholderText,
attributes: [NSAttributedString.Key.foregroundColor: Color.iPhoneGrayColor, NSAttributedString.Key.font: UIFont(name: "SourceSansPro-Regular", size: 10)!])
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
But, my placeholder font size is getting overridden by textfield.font, so I am unable to get placeholder of size 10. Where am I going wrong? Tried this for couple of hours now. Any help will be appreciated.
Simply set the placeholder after setting the font since setting the font also applies to the placeholder (see https://developer.apple.com/documentation/uikit/uitextfield/1619604-font):
textField.font = ...
textField.textColor = ...
textField.attributedPlaceholder = ...
Try this code into your viewDidLoad() method:
textField.attributedPlaceholder = NSAttributedString(string: placeholderText, attributes: [NSAttributedString.Key.foregroundColor: Color.iPhoneGrayColor, NSAttributedString.Key.font: UIFont(name: "SourceSansPro-Regular", size: 10)!])
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
Just try this code, take the UITextFieldEditingChanged action outlet and use as below.
#IBAction func nameTextFieldEditingChanged(_ sender: UITextField) {
if sender.text?.isEmpty ?? true {
//placeholder text size set here
textField.font = UIFont(name: "SourceSansPro-Regular", size: 10)!
} else {
// When user starting typing
textField.textColor = UIColor.black
textField.font = UIFont(name: "SourceSansPro-Regular", size: 14)!
}
}
If any doubt please comment ].
Just try this code may help you for further:
var myMutableStringTitle = NSMutableAttributedString()
let Name = "Enter Title" // PlaceHolderText
myMutableStringTitle = NSMutableAttributedString(string:Name, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 20.0)!]) // Font
myMutableStringTitle.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range:NSRange(location:0,length:Name.characters.count)) // Color
txtTitle.attributedPlaceholder = myMutableStringTitle
I am setting the title as follows, but I want to change the color of the text as well, but there is no textattributes, I wonder how it can be done ?
self.tabBarController?.navigationItem.title = "Settings"
I tried the following as well, but it did not even show the label.
let navLabel = UILabel()
let navTitle = NSMutableAttributedString(string: "Settings", attributes:[
NSAttributedString.Key.foregroundColor: UIColor.blue,
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 17.0, weight: UIFont.Weight.light)])
navLabel.attributedText = navTitle
self.tabBarController?.navigationItem.titleView = navTitle
try this code, I hope it helps you.
Build Settings\Swift Language Version: 4.1

let attrsNormal = [NSAttributedStringKey.foregroundColor : UIColor.black,

The size of label is right ? Call fitThatSize
I am using attributed text property to set custom placeholder font in UITExtfield. But my placeholder text is not vertically centered.Here is preview
let font = UIFont(name: Font.myFont.name, size: 15)!
let attributes = [
NSForegroundColorAttributeName: UIColor.cadetGrey,
NSFontAttributeName: font
]
exampleTextField.attributedPlaceholder = NSAttributedString(string: "Example Placeholder",
attributes: attributes)
I tried to add
let centeredParagraphStyle = NSMutableParagraphStyle()
centeredParagraphStyle.alignment = .center
to attribute still no luck. I also tried to use SizeToFit() on my UITextBox but no luck at all
This worked for me in Swift 5:
let unitText = NSAttributedString(string: "\(unit)", attributes: [NSAttributedString.Key.foregroundColor: MyColors.doveGray, NSAttributedString.Key.baselineOffset:2])
Try like this :
let centeredParagraphStyle = NSMutableParagraphStyle()
centeredParagraphStyle.alignment = .center
let attributes: [String : Any] = [NSParagraphStyleAttributeName: centeredParagraphStyle]
This is will set both placeholder and text input by user in center.
exampleTextField.textAlignment = .center
To center both vertically and horizontally.
exampleTextField.contentVerticalAlignment = UIControlContentVerticalAlignment.center
exampleTextField.textAlignment = .center
OR
This is will only set placeholder in center whereas the text input by user will remain at it's default position i.e left align
let font = UIFont(name: Font.myFont.name, size: 15)!
let centeredParagraphStyle = NSMutableParagraphStyle()
centeredParagraphStyle.alignment = .center
// add attribute of NSMutableParagraphStyle
let attributes = [
NSForegroundColorAttributeName: UIColor.gray,
NSFontAttributeName: font,
NSParagraphStyleAttributeName: centeredParagraphStyle
]
exampleTextField.attributedPlaceholder = NSAttributedString(string: "Example Placeholder",
attributes: attributes)
I get different line height in textView with using same font
How to set fixed line height?
I have done a lot of attempts, any help is appreciated, thanks
set NSMutableParagraphStyle lineSpacing is useless
set lineHeightMultiple is to make the difference more obvious

import UIKit

let view = UIView(frame: CGRect(x: 0, y: 0, width: 400, height: 1000))
let data: [String] = [

for text: String in data {
var backgroundColor = UIColor(red:0.13, green:0.38, blue:0.95, alpha:1.00)
if stripe {
backgroundColor = UIColor(red:0.92, green:0.12, blue:0.38, alpha:1.00)
}
let contentAttributedString = NSAttributedString(string: text, attributes: [
NSBackgroundColorAttributeName: backgroundColor,
NSParagraphStyleAttributeName: paragraphStyle,
NSFontAttributeName: bodyFont
])
mutableAttributedString.append(contentAttributedString)
stripe = !stripe
// add newline character
let newlineAttributedString = NSAttributedString(string: "\n")
mutableAttributedString.append(newlineAttributedString)
}
textView.attributedText = mutableAttributedString
view.addSubview(textView)
PlaygroundPage.current.liveView = view
I found the reason, the newlineAttributedString also need NSFontAttributeName
let newlineAttributedString = NSAttributedString(string: "\n", attributes: [
NSFontAttributeName: bodyFont
])
mutableAttributedString.appendAttributedString(newlineAttributedString)
Code that worked in Xcode 6.2 no longer works and I'm having trouble figuring out how to fix it. String attributes are now ignored unless I set default text. Here's what I've got right now:
let font = UIFont(name: "Arial-BoldMT", size: 42.0)!
let textStyle = NSMutableParagraphStyle.defaultParagraphStyle().mutableCopy() as! NSMutableParagraphStyle
textStyle.alignment = NSTextAlignment.Center
let textColor = UIColor.whiteColor()
var shadow = NSShadow()
shadow.shadowColor = UIColor.blackColor()
shadow.shadowOffset = CGSizeMake(2.0,2.0)
var attr = [String:NSObject]()
attr = [
NSFontAttributeName: font,
NSForegroundColorAttributeName: textColor,
NSParagraphStyleAttributeName: textStyle,
NSShadowAttributeName: shadow
]
let placeholderText = NSAttributedString(string: "", attributes: attr)
textView.attributedText = placeholderText
If you change the placeHolderText to NSAttributedString(string: " ", attributes: attr) you can then change the UITextView's text by changing its text property and the new text will have all the same attributes.
I hope that answers your question.
