unable to change size of font in UILabel

Question

I am instantiating a UILabel programatically. The label displays numbers in a count down. The problem is I seem unable to increase the font size dispute the fact I have the following code

[self.viewAnimation addSubview:lblCounter];
    [lblCounter setAdjustsFontSizeToFitWidth:NO];
    [lblCounter setMinimumFontSize:30.0];
    [lblCounter setTextAlignment:UITextAlignmentCenter];

The UILabel is plenty big enough to fit size 30 font.

Anyone had similar problems?

使用[lblCounter setFont:[UIFont systemFontOfSize:30]] ，最小字体大小仅在adjustsFontSizeToFitWidth为“是”时适用，并调整字体在裁剪前将缩小多少。
