您可以在界面构建器中执行此操作。此GIF将向您展示如何增加文本的一个部分的大小，并可能更改其字体。

在代码中执行此操作：

NSString *fullString = @"This bit's plain. This bit's bigger";
NSRange rangeOfPlainBit = [fullString rangeOfString:@"This bit's plain."];
NSRange rangeOfBigBit = [fullString rangeOfString:@"This bit's bigger"];

NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString:fullString];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"My-font" size:15.0],
                                NSForegroundColorAttributeName: [UIColor whiteColor]}
                        range:rangeOfPlainBit];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"My-font" size:25.0],
                                NSForegroundColorAttributeName: [UIColor whiteColor]}
                        range:rangeOfBigBit];

[self.myButton setAttributedTitle:attributedText forState:UIControlStateNormal];

只需更改标题的字体大小。

迅速： button.titleLabel.font = UIFont.systemFontOfSize（FONTSIZE）
