为什么要用new plus.nativeObj.View在APP端实现弹窗？因为uni.showModal在APP端太难看了。
AppPopupView弹窗函数参数定义
参数一:弹窗信息(所有属性可不填，会有默认值)
1.title:"", //标题
2.content:"", //内容
3.confirmBoxColor:"", //确认按钮背景色
4.cancelText:"", //取消按钮文字
5.confirmText:" //确认按钮文字"
6.showCancel: false, // 是否显示取消按钮 是:true(默认) 否:false
7.maskClick: true // 是否允许点击遮罩层关闭弹窗 是:true 否:false(默认)
参数二(cd1):点击确认按钮执行逻辑，
参数三(cd2):点击取消按钮执行逻辑。
/utils/AppPopupView.js 定义弹窗文件
