uni-app 项目调试遇到的问题

使用真机调试手机设置

启动开发者模式

锤子手机：设置-关于本机-连续点击5次软件版本

启动usb调试

锤子手机：设置-全局高级设置-开发者选项-USB调试

真机调试发布完之后出现是循环，无法进入APP

出现问题原因：
出现这个问题是因为自己写的代码有问题，程序校验是否有新版，如果有新版本自动下载安装，在判断新版本的时候放到服务器的安装包不是新版本安装包，所以会一直校验，反复安装。

uni-app 启动时报 Uncaught SyntaxError: Duplicate data property in object literal not allowed in strict mode at app-view.js:5132

启动程序后HBuilderX控制台提示Uncaught SyntaxError: Duplicate data property in object literal not allowed in strict mode at app-view.js:66368，APP界面空白
原因：标签中存在重复的属性

<input class="input" focus :focus="billFocus"  placeholder="请扫描" />

输入框重新聚焦

内容提交之后，输入框重新聚焦
直接写 this.rfidFocus=true 是不生效的，要先将rfidFocus失焦，再聚焦.

this.rfidFocus=false;
this.rfidFocus=true;

data() {
	return {
		rfidFocus:true
	}
}
<input :focus="rfidFocus" class="input" type="text"  placeholder="请扫描RFID"  />

uni-app 图标组件uni-icons点击事件

直接使用@click在浏览测试的时候可以正常调用，在pda上使用时只生效了一次。解决方式修改为 @click.native原生点击事件

<uni-icons custom-prefix="iconfont" type="icon-exchangerate" size="40" @click.native="changeInput">uni-icons>
