Xcode8中测试真机的时候,或者打包的时候出现的问题

打包的时候

School has conflicting provisioning settings. School is automatically signed, but provisioning profile SCHOOL_PRO has been manually specified. Set the provisioning profile value to "Automatic" in the build
settings editor, or switch to manual signing in the project editor.

Code signing is required for product type 'Application' in SDK 'iOS 10.0'

修改 General 中把 Automatically manage sugning 关掉;然后填写下面的release

测试真机的时候,还是打开 Automatically manage sugning,不然会出现A valid provisioning profile for this executable was not found.  的报错,真机运行不了的
