uibutton点击按钮时title变大 松开时变小

结合 NSMutableAttributedString的各种属性可以做很多事情

下面只是一种小情况

UIButton *button = [UIButton buttonWithType:(UIButtonTypeCustom)];

button.frame = CGRectMake(100, 100, 100, 30);

button.backgroundColor = [UIColor redColor];

NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:@"压缩图片"];

[str addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:12.0] range:NSMakeRange(0, 4)];

[button setAttributedTitle:str forState:(UIControlStateNormal)];

NSMutableAttributedString *str1 = [[NSMutableAttributedString alloc] initWithString:@"压缩图片"];

[str1 addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20.0] range:NSMakeRange(0, 4)];

[button setAttributedTitle:str1 forState:(UIControlStateHighlighted)];

[self.view addSubview:button];
