更改uibutton的文本大小无效

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

我在故事板中创建了一个按钮，我正在尝试通过编程方式设置字体大小和字体样式如下:

_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?

但是按钮文本大小保持不变。我遗漏了什么东西?
