Subclassing UIButton and setting fontSize

Question

i am subclassing UIButton to set some defaults for the app, but i for some reason i am not able to change the font size.

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // id button, set defaults
        [self setTintColor:[UIColor blueColor]];
        [self.titleLabel setFont:[UIFont systemFontOfSize:40.0]];
        [self.layer setBorderWidth:1.0f];
        [self.layer setBorderColor:[[UIColor blackColor] CGColor]];
    }
    return self;
}

I can change the color and the other propertise, but not the fontsize, it has no effect?

    idButton *LButton = [idButton buttonWithType:UIButtonTypeRoundedRect];
    [LButton setTitle:@"Login" forState:UIControlStateNormal];
    LButton.frame = CGRectMake(0, buttonY+(buttonHeight/2), screenWidth, buttonHeight);
    [self addSubview:LButton];

Answer 1

The problem with your code is that UIButton's method setTitle:forState: will reset the font back to the default.

One solution would be to override this method to use the NSAttributedString. This will also allow you to set other attributes:

- (void) setTitle:(NSString *)customTitle forState:(UIControlState)state {
    if (customTitle) {
        NSMutableAttributedString *mas = [[NSMutableAttributedString alloc] initWithString:customTitle];
        NSRange range = NSMakeRange(0, [customTitle length]);

        [mas addAttribute:NSFontAttributeName
                    value:[UIFont systemFontOfSize:40.0]
                    range:range];

        [mas addAttribute:NSKernAttributeName
                    value:@(1.1)
                    range:range];

        [self setAttributedTitle:mas forState:state];
    } else {
        [super setTitle:customTitle forState:state];
    }
}
