swift:

使用

//上文下圖
let btnTop = UIButton(frame: CGRect(x: 0, y: 100, width: 170, height: 70))
btnTop.titleLabel?.font = UIFont.systemFont(ofSize: 20)
btnTop.setTitleColor(UIColor.black, for: .normal)
btnTop.backgroundColor = UIColor.cyan
btnTop.set(image: UIImage(named: "btnAlphaControl"), title: "標(biāo)題在上方", titlePosition: .top, space: 10, state: .normal)
view.addSubview(btnTop)

// 上圖下文
btnBottom.lableToImage(titlePosition: .bottom, space: 10)
//左圖右文
btnBottom.lableToImage(titlePosition: .right, space: 10)
//左文右圖
btnBottom.lableToImage(titlePosition: .left, space: 10)

實(shí)現(xiàn)：

//已有文字和圖片,直接調(diào)整位置
@objc func lableToImage(titlePosition: UIView.ContentMode, space: CGFloat){
    
    let imageSize = self.imageRect(forContentRect: self.frame)
    let titleFont = self.titleLabel?.font!
    let titleSize = self.titleLabel?.text?.size(withAttributes: [kCTFontAttributeName as NSAttributedString.Key: titleFont!]) ?? CGSize.zero
    
    var titleInsets: UIEdgeInsets
    var imageInsets: UIEdgeInsets
    
    switch titlePosition {
    case .top:
        //標(biāo)題在上
        titleInsets = UIEdgeInsets(top: -(imageSize.height+titleSize.height+space)/2, left: -imageSize.width, bottom: 0, right: 0)
        imageInsets = UIEdgeInsets(top: (imageSize.height + titleSize.height + space)/2, left: 0, bottom: 0, right: -titleSize.width)
        
    case .left:
        //標(biāo)題在左
        titleInsets = UIEdgeInsets(top: 0, left: -(imageSize.width*2), bottom: 0, right: 0)
        imageInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: -(titleSize.width*2+space))
        
    case .bottom:
        //標(biāo)題在下
        titleInsets = UIEdgeInsets(top: (imageSize.height+titleSize.height+space)/2, left: -imageSize.width, bottom: 0, right: 0)
        imageInsets = UIEdgeInsets(top: -(imageSize.height + titleSize.height + space)/2, left: 0, bottom: 0, right: -titleSize.width)
        
    case .right:
        //標(biāo)題在右
        titleInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: -space)
        imageInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
        
    default:

        imageInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
        break

}

OC:

使用：

//上文下圖
UIButton *btnTop = [[UIButton alloc] initWithFrame:CGRectMake(50, 100, 70, 70)];
[btnTop setTitle:@"上邊" forState:UIControlStateNormal];
[btnTop setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[btnTop setImage:[UIImage imageNamed:@"btnAlphaControl"] forState:UIControlStateNormal];
btnTop.titleLabel.font = [UIFont systemFontOfSize:20];
[btnTop titlePosition:UIViewContentModeTop space:10];
[btnTop setBackgroundColor:[UIColor cyanColor]];
[self.view addSubview:btnTop];

// 上圖下文
[btnTop titlePosition:UIViewContentModeBottom space:10];
//左圖右文
[btnTop titlePosition:UIViewContentModeRight space:10];
//左文右圖
[btnTop titlePosition:UIViewContentModeLeft space:10];

//方便理解的一句話:left以右為正方向,right以左為正方向,top向下為正,bottom向上為正
