Code Sign error: The identity ‘iPhone Developer’ doesn’t match any valid certifica

1.直接Build and run，找不到SDK 2.0

開啟工程, 在菜單中選擇Projects,  General標籤中的最下面有一個
Base SDK for All Configurations (預設的是 iPhone Device 2.0)，改成IOS2.0

 

2.再次build，出現Code Sign error: The identity 'iPhone Developer' doesn't match any valid certificate/private key pair in the default key

這是因為預設Build選擇的是裝置, 如果改成Simulator 則可以編譯通過,並在模擬器裡運行　　change your build settings to Simulator

 

Check if you are building for device instead of simulator. Go to Xcode menu 'Project' -> 'Set Active SDK' change from 'Device' to 'Simulator'

 **********備註 ********** **********

I　had the same issue with another Apple sample app. The only way I could resolve it (in fact, the only way I could get the option of running in the simulator at all) was to change from debug to release and back. The dropdown still shows Base SDK Missing but if you click it, the simulator options are there and it builds.

 

3.go to menu->project->edit project setting->build. find code signing section (you can type 'code' in the quick search) in the code signing identity and set the value to 'Don't Code Sign'
