关于环信iosDemo

下载下来直接爆红，无法真机测试，是随SDK包一起下载的Demo不是扫码下载的，是需要进行什么修改么，错误代码如下，
Check dependencies




Code Sign error: No matching provisioning profiles found: No provisioning profiles with a valid signing identity (i.e. certificate and private key pair) matching the bundle identifier “com.easemob.enterprise.demo.ui” were found.
 
那个build setting 中得Coding Signing的Debug已经改成Iphone Developer了
