Question

我想將我的UIButton標題設置為===還沒有帳戶嗎？ 注冊

如何使一些文字加粗。

    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];

無法實現屬性字符串..

像這樣在這里設置您的按鈕文字...

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

請嘗試此功能...

-(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;
}
