Swift3 Different Font in The All of The UIview with Localization Each

Swift3 different font in the All of the UIView with Localization each

As I can see, there you have 3 tasks to do.

1. Map font name with current language code
2. Get regular font from the name
3. Get bold font from the name (optionally, but spotted from your code)

1. Map font name with current language code

In order to do that you need to get that code and write a switch statement.

It can look like this (may vary depending on your needs)

func languageCode() -> String? {
    return NSLocale.autoupdatingCurrent.languageCode
}

func localizedFontName() -> String {
    let defaultFont = "Arial"
    guard let code = languageCode() else {
        return defaultFont
    }
    switch(code) {
    case "en":
        return "Helvetica"
    case "fr":
        return "Menlo"
    default:
        return defaultFont
    }
}

Please refer to NSLocale documentation for more info.

2. Get regular font from the name

It can be achieved by using UIFontDescriptor

let DefaultFontSize: CGFloat = 12.0
func font(from name: String) -> UIFont {
    let descriptor = UIFontDescriptor(name: name, size: DefaultFontSize)
    return UIFont(descriptor: descriptor, size: DefaultFontSize)
}

3. Get bold font from the name

And the last task can be done via UIFontDescriptor as well.

let BoldFontSize: CGFloat = 12.0
func boldFont(from name: String) -> UIFont {
    let regularFont = font(from: name)
    guard let descriptor = regularFont.fontDescriptor
                                      .withSymbolicTraits(.traitBold) else {
        return regularFont
    }
    return UIFont(descriptor: descriptor, size: BoldFontSize)
}

Ultimately it all can be used like this:

let nameFont = boldFont(from: localizedFontName())
let nameString = NSAttributedString(string: "username ",
                                    attributes: [NSFontAttributeName: nameFont])

let surnameFont = font(from: localizedFontName())
let surnameString = NSAttributedString(string: "gender",
                                       attributes: [NSFontAttributeName: surnameFont])

Set top alignment for labels with different font sizes, Swift 3

solution by programming:

you may use UILabel's attributed string property to handle this situation.

attribute options have one option named "NSBaselineOffsetAttributeName", it will render text offset the default baseline. and this offset can be measured through UIFont properties

offset = ascender - capHeight

code sample:

 class CustomViewController: UIViewController {

        override func viewDidLoad() {
            super.viewDidLoad()    
            setupViews()
        }

        let currencyLabel: UILabel = {
            let label = UILabel()
            let font = UIFont.systemFont(ofSize: 50)

            // measure baseline offset
            let offset = font.ascender - font.capHeight

            label.attributedText = NSAttributedString(string: "$", attributes: [NSFontAttributeName: font, NSBaselineOffsetAttributeName: offset])
            label.translatesAutoresizingMaskIntoConstraints = false
            label.backgroundColor = UIColor.blue
            return label
        }()

        let costLabel: UILabel = {
            let label = UILabel()
            let font = UIFont.systemFont(ofSize: 150)
            let offset = font.ascender - font.capHeight
            label.attributedText = NSAttributedString(string: "15", attributes: [NSFontAttributeName: font, NSBaselineOffsetAttributeName: offset])
            label.translatesAutoresizingMaskIntoConstraints = false
            label.backgroundColor = UIColor.green
            return label
        }()

        func setupViews() {
            view.backgroundColor = UIColor.red

            view.addSubview(currencyLabel)
            view.addSubview(costLabel)

            view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|-20-[v0]-[v1]", options: NSLayoutFormatOptions(), metrics: nil, views: ["v0": currencyLabel, "v1": costLabel]))
            view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|-20-[v0]", options: NSLayoutFormatOptions(), metrics: nil, views: ["v0": currencyLabel]))
            view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|-20-[v0]", options: NSLayoutFormatOptions(), metrics: nil, views: ["v0": costLabel]))
        }

    }

How to set a custom font for entire iOS app without specifying size

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self setFontFamily:@"FagoOfficeSans-Regular" forView:self.view andSubViews:YES];
}

-(void)setFontFamily:(NSString*)fontFamily forView:(UIView*)view andSubViews:(BOOL)isSubViews
{
    if ([view isKindOfClass:[UILabel class]])
    {
        UILabel *lbl = (UILabel *)view;
        [lbl setFont:[UIFont fontWithName:fontFamily size:[[lbl font] pointSize]]];
    }

    if (isSubViews)
    {
        for (UIView *sview in view.subviews)
        {
            [self setFontFamily:fontFamily forView:sview andSubViews:YES];
        }
    }

Swift 3 - Add Text to UIView Pop up

You can try

popup = UIView(frame: CGRect(x: 100, y: 200, width: 200, height: 200))

let lb = UILabel(frame: CGRect(x: 100, y: 200, width: 200, height: 200))
lb.text="anything"
popup.backgroundColor = UIColor.redColor

// show on screen
self.view.addSubview(popup)
popup.addSubview(lb)
lb.center = popup.center

Swift 3 how to animate font in a button

You can store the grab the original font size and scale it similar to how you do it with the frame and background color:

func animate() {

    // Original frame and background color
    let originalFontSize = self.playButton.titleLabel?.font.pointSize

    // First UIView.addKeyframe()
    UIView.addKeyframe(withRelativeStartTime: 0.0, relativeDuration: 0.5) {
        self.playButton.titleLabel?.font = UIFont.systemFont(ofSize: originalFontSize!*1.2)
        // Other animations ...
    }

    // Second UIView.addKeyframe() to return to normal
    UIView.addKeyframe(withRelativeStartTime: 0.5, relativeDuration: 0.5) {
        self.playButton.titleLabel?.font = UIFont.systemFont(ofSize: originalFontSize!)
        // Other animations ...

}

Set the separator(UIView)'s color based on the date and text in Swift 3

i think you are comparing string objects that's why this is not working try this :

let today = Date()
let headerDate = "18 May 2017"

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "dd MMM yyyy" //Your date format
dateFormatter.timeZone = TimeZone(abbreviation: "GMT+0:00")
//Current time zone
let date = dateFormatter.date(from: headerDate) //according to date format your date string
print(date ?? "")

if today < date{
    cell.separator.backgroundColor = UIColor(red: 1, green: 0.8314, blue: 0.1569, alpha: 1)
} else if cell.jobDetail.text == "Cancel" {
    cell.separator.backgroundColor = UIColor.red
}
