Answer 1

这就是你需要的

  UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
  btn.frame = CGRectMake(5,10,300,20);
  [self.view addSubview:btn];

  NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"100 Photos"]];
  [attrStr addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 3)];
  [btn setAttributedTitle:attrStr forState:UIControlStateNormal];

Answer 3

对于swift 3：

let button = UIButton()
let mainTitle = "200"
let subtitle = "Members"

let attrText1 = NSMutableAttributedString(string: mainTitle)
attrText1.addAttribute(NSFontAttributeName, value: 15, range: NSMakeRange(0, attrText1.length))
attrText1.addAttribute(NSForegroundColorAttributeName, value: UIColor.black, range: NSMakeRange(0, attrText1.length))


let attrText2 = NSMutableAttributedString(string: subtitle)
attrText2.addAttribute(NSFontAttributeName, value: 15, range: NSMakeRange(0, attrText2.length))
attrText2.addAttribute(NSForegroundColorAttributeName, value: UIColor.yellow, range: NSMakeRange(0, attrText2.length))

let attributedText = NSMutableAttributedString()
attributedText.append(attrText1)
attributedText.append(attrText2)

//Center align
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center

attributedText.addAttribute(NSParagraphStyleAttributeName, value: paragraphStyle, range: NSMakeRange(0,attributedText.length))

button.setAttributedTitle(attributedText, for: .normal)

试试这个

NSMutableAttributedString *mutableString = [[NSMutableAttributedString alloc] initWithString:@"ThisIsAttributed"];
[mutableString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,4)];
[mutableString addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor]  range:NSMakeRange(5,2)];
[button setAttributedTitle:mutableString forState:UIControlStateNormal];

[button setAttributedTitle:someAttributedText forState:UIControlStateNormal];
