Answer 2

This way you can set the fontSize and can handle it in just one class.

1. Created an extension of UIButton and added following code:

- (void)awakeFromNib{

    [super awakeFromNib];

    [self setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [self.titleLabel setFont:[UIFont fontWithName:@"font" 
                                     size:self.titleLabel.font.pointSize]];
    [self setContentHorizontalAlignment:UIControlContentHorizontalAlignmentCenter];
}

2.1 Create UIButton inside Code

Now if you create a UIButton inside your code, #import the extension of yourUIButton` and create the Button.

2.2 Create Button in Interface Builder

If you create the UIButton inside the Interface Builder, select the UIButton, go to the Identity Inspector and add the created extension as class for the UIButton.
