Use the defaultTextAttributes property of UITextField. It will handle the conversion to NSAttributedString for you and apply the attributes you set. For example:

    NSMutableDictionary *attrs = [self.textField.defaultTextAttributes mutableCopy];
[attrs addEntriesFromDictionary:@{
    NSKernAttributeName: @18,
    NSUnderlineColorAttributeName: [UIColor grayColor],
    NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle | NSUnderlinePatternDash)
}];
self.textField.defaultTextAttributes = attrs;
