删除证书、配置文件并重新创建。安装它。这是最好的方法。

我也遇到过同样的问题，可能还有其他原因:

While testing i set my date to some future date and profile got expired. As result this issue was generated.

But i solved by setting date of iphone to current date as a result profile was not expired. 

我也有同样的问题。我所做的是: 1. 清理目标 2. 退出xcode 3.重启xcode 4. 重建。 这招奏效了。

这招对我很管用: 从xcode，窗口->设备和模拟器，右键单击您的手机(s)，解除配对。 然后重新连接一切，构建，完成。

这可能是因为配置门户无法识别您的iphone。

解决方案:

In Xcode, Goto --> Build --> clean all targets. In "Groups & Files" -->Target --> expand it --> right click your app and select Clean "your app" Goto->Window-->Organizer In the Devices tab on the left, select your iphone In the Provisioning section of the selected iphone delete all the current profiles (if any) Unplug your iPhone and replug it in. Goto->Window-->Organizer-->right click your iPhone -->Add device to provisioning portal Now make sure you have selected the appropriate code signing identity in edit project settings -> build --> code signing

构建并运行。

在我的情况下，设备日期和时间是手动更改的。为了解决这个问题，将日期和时间设置为自动。
