You may find it difficult to adjust the default button. However you can use any view you want with a custom button.
您可能会发现很难调整默认按钮。但是，您可以通过自定义按钮使用任何您想要的视图。
Here's an article on creating views with rounded corners: http://iphonedevelopment.blogspot.com/2008/11/creating-transparent-uiviews-rounded.html

Rounded rect button's color can be changed to any color with the background color property in IB as well as through coding, but can not change its color to transparent color easily. For that, you better use a custom button with either rounded image or set layer as demonstrated in the example and don't forget to add Quartz Core framework in you project as well as to import it in your class.
圆形矩形按钮的颜色可以通过IB中的背景颜色属性以及通过编码更改为任何颜色，但不能轻易将其颜色更改为透明色。为此，您最好使用带有圆形图像或设置图层的自定义按钮，如示例中所示，并且不要忘记在您的项目中添加 Quartz Core 框架以及将其导入您的类中。
UIBUtton *myBtn = [UIButton buttonWithType:UIbuttonTypeCustom];
myBtn.frame = frame; //your desired size
myBtn.clipsToBounds = YES;
myBtn.layer.cornerRadius = 5.0f;
[self.view addSubView:myBtn];

You can use a custom UIButtonwith custom images for backgroundimage for each state. Just make the different states of your rounded button in photoshop for example.
您可以UIButton为每个州的背景图像使用自定义图像。例如，只需在 Photoshop 中制作圆形按钮的不同状态。
