Lost connection to “iPhone Name”. Restore the connection to “iPhone Name” and run “APP Name” again, or if “APP Name” is still running, you can attach to it by selecting Debug > Attach to Process > “APP Name”.

连接真机调试状态突然提示这个，经过排查是因为升级了Xcode8后，Interface Builder的Opens in 自动设置为Latest Xcode (8.0)，会对XIB做了一些版本设置，导致多个View-[UINit instantiateWithOwner:options:]时调用CGDataProviderCreateWithCopyOfData分配内存过大，引起crash，设置为Xcode 7.x后APP运行并调试正常，有相同问题的可以试试，具体原因未查明，知道的告知下，谢谢！
