iOS 真机调试不能连接网络的排错过程

开发环境：

macOS 10.12.1

Xcode 8.1

Qt 5.8

gSOAP 2.8

iPhone 6S+iOS 10.1.1

 

问题：

使用 Qt Quick 写了一个跨平台的应用，在Win10、Android、macOS下都已经正常运行，但是连接到 iOS 真机调试的时候，gSOAP 调用 Webservice 总是返回错误代码28，我就根据百度出来的下面的 gSOAP 错误代码表一直在寻找有关 SOAP_DIME_END 的错误。

 

返回值错误代码表（ERROR CODE）

SOAP_ERR	-1

实在解决不了了，于是下载了 iOS 10.0 Simulator ，在 iOS 虚拟机上跑了一下，没有问题，说明可能是真机系统权限的问题。

因为我用的手机卡放在我的 Mate8 上，iPhone 开发机上没有卡，是连接的 WIFI，突然想到，是不是应该把卡插到 iPhone 开发机上试一下。

插上卡之后，手机立马提示是否允许使用网络，同意之后，就可以联网了。然后在【使用无线局域网与蜂窝移动的应用】中可以看到我的应用了。

其实前面说了一大堆都是废话，只不过是记录了一下我昨天呕心沥血大半天的填坑过程。总而言之，你如果真机调试 iOS 应用，最好插着你的 SIM 卡。
