Changing text size of uibutton doesn't work

Question

I've created a button in story board and I'm trying to set font size and font style programmatically as follows:

_login.titleLabel.textColor = [UIColor whiteColor];
_login.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
[_login.titleLabel setFont:[UIFont boldSystemFontOfSize:13.f]];
[_login setBackgroundColor:[UIColor purpleColor]];

But the button text size remains the same. Am I missing something?

First verify for IBOutlet part. Your button should not be nil when try to change its property. — Apurv, Apr 29 '16 at 05:37
Someone gave you a -1 so I gave you a +1, because I don't think this is a -1 question. You have already got a good answer. — J. Lopes, Apr 29 '16 at 13:51

Try this:

[_login.titleLabel setFont:[UIFont systemFontOfSize:10]

Option A:

[_login.titleLabel setFont:[UIFont boldSystemFontOfSize:15.0f*Ratio]];

objective c: both will work perfectly

(first)

[_loginButton.titleLabel setFont: [_loginButton.titleLabel.font fontWithSize: size]];

(second)

_loginButton.titleLabel.font =[UIFont boldSystemFontOfSize:20.f];

swift: if anybody want in swift

_loginButton.titleLabel?.font = _loginButton.titleLabel?.font.fontWithSize(sizeYouWant)

for more datails you can verify: Set UIButton title UILabel font size programmatically

Try this, Use yourButton.titleLabel.font

_login.titleLabel.font = [UIFont boldSystemFontOfSize:13.0f];
