    CGFloat heightSpace = 10.0f;
    
    //設定按鈕内邊距
    imgViewSize = button.imageView.bounds.size;
    titleSize = button.titleLabel.bounds.size;
    btnSize = button.bounds.size;
    
    imageViewEdge = UIEdgeInsetsMake(heightSpace,0.0, btnSize.height -imgViewSize.height - heightSpace, - titleSize.width);
    [button setImageEdgeInsets:imageViewEdge];

調用示例：

[Btn setImage:[UIImage imageNamed:@"test.png"] forState:UIControlStateNormal];
    [Btn setTitle:@"測試" forState:UIControlStateNormal];
    [Btn setTitleColor:[UIColor lightGrayColor] forState:UIControlStateNormal];
    [self setButtonContentCenter:Btn];
