you can use NSAttributedString to add properties to TextField

let textAttributes: [NSAttributedString.Key: Any] = [
        NSAttributedString.Key.strokeColor: /* TODO: fill in appropriate UIColor */,
        NSAttributedString.Key.foregroundColor: /* TODO: fill in appropriate UIColor */,
        NSAttributedString.Key.font: UIFont(name: "HelveticaNeue-CondensedBlack", size: 40)!,
        NSAttributedString.Key.strokeWidth:  /* TODO: fill in appropriate Float */
    ]

yourTextField.defaultTextAttributes = textAttributes

Swift 4 is this:

yourTextField.font =  UIFont.init(name: (Montserrat.bold.rawValue), size: 18.0)

Instead Monserrat use your font

yes you can do it.

but you have to change the textField's frame also(to show the full(height) text)

[tFild_1 setFont:[UIFont fontWithName:@"Helvetica Neue" size:17]];

instead of "Helvetica Neue" use your font name.

thanx,

If you want to simply change your textfield's font size , and not change it's font style at the same time , code below may be work : `

UITextField *yourTextField = [[UITextField alloc]init];
CGFloat yourSelectedFontSize = 14.0 ;
UIFont *yourNewSameStyleFont = [yourTextField.font fontWithSize:yourSelectedFontSize];
yourTextField.font = yourNewSameStyleFont ;

One thing you have to note is that : when you change your textfield's font size , you should always pay attention to your textfield view's height , keep your textfiled's height taller than your font height !

You can have a try !
