ios - 如何使 UIButton 的一些文字变粗

Question

我想将我的 UIButton 标题设置为 === 没有帐户？ 注册

如何使一些文本加粗。

    UIButton *signUpButton = [[UIButton alloc]initWithFrame:CGRectMake(40, 270, 240, 40)];
    [signUpButton setTitle:@"Don`t have an account? Sign Up" forState:UIControlStateNormal];
    [signUpButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    signUpButton.titleLabel.font = [UIFont systemFontOfSize:14];
    [signUpButton setBackgroundColor:[UIColor clearColor]];
    [signUpButton addTarget:self action:@selector(signUpAction) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:signUpButton];

无法实现属性字符串..

Answer 1

在这里设置你的按钮文本...

[yourbutton setAttributedTitle:[self UnderLineTextString:strString]
        forState:UIControlStateNormal];

请试试这个功能...

-(NSMutableAttributedString *)UnderLineTextString:(NSString *)str
{
    NSMutableAttributedString *titleString = [[NSMutableAttributedString alloc] initWithString:str];

    [titleString addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:20.0] range:NSMakeRange(0, [titleString length])];// set your text lenght..

    return titleString;
}
