* `QMUIToastView`是一个用来显示toast的控件，其主要结构包括：`backgroundView`、`contentView`，这两个view都是通过外部赋值获取，默认使用`QMUIToastBackgroundView`和`QMUIToastContentView`。
|
|||
|
|
*
|
|||
|
|
* 拓展性：`QMUIToastBackgroundView`和`QMUIToastContentView`是QMUI提供的默认的view，这两个view都可以通过appearance来修改样式，如果这两个view满足不了需求，那么也可以通过新建自定义的view来代替这两个view。另外，QMUI也提供了默认的toastAnimator来实现ToastView的显示和隐藏动画，如果需要重新定义一套动画，可以继承`QMUIToastAnimator`并且实现`QMUIToastAnimatorDelegate`中的协议就可以自定义自己的一套动画。
|
|||
|
|
*
|
|||
|
|
* 样式自定义：建议通过 tintColor 统一修改整个 toastView 的内容样式。当然你也可以单独修改 contentView.tintColor。默认情况下 QMUIToastView.tintColor = UIColorWhite。
|
|||
|
|
*
|
|||
|
|
* 建议使用`QMUIToastView`的时候，再封装一层，具体可以参考`QMUITips`这个类。
