如果放在onLoad里面，当数据量比较大的时候也会遇见相同的问题，这是一个性能问题。参考issues14
不知道你方便提供一下你使用该组件时的数据不，即pickerValueArray

设置无效是在第一次显示，通常是在编辑信息返显时，页面加载完成就把默认值设置上，弹出层时默认值无效，关闭后再打开会把默认值设置上。应该是必现的问题。我看了源码中是在显示时初始化的组件，我的解决方式是在设置默认值时手动调用了初始化initpicker函数，最开始我把show函数中的initpicker删除掉了，但是之后好像引发了一个bug，我又加上了。最后就是在又设置默认值的地方手动调用了一次初始化的函数

组件应该加一个监控，如果pickerValueDefault变化时，应该触发initPicker函数
