有什么方法可以改回来吗？或者它只是简单地指向Bundle Identifier,即在Product Bundle Identifier字段中写$(BUNDLE_IDENTIFIER)？
解决方法
从Xcode 7.0发行说明：
The new build setting Product Bundle Identifier (PRODUCT_BUNDLE_IDENTIFIER) is the recommended place to set the Bundle Identifier for a target. The target’s Info.plist should be configured to use this build setting by referencing it as $(PRODUCT_BUNDLE_IDENTIFIER) in the value for the CFBundleIdentifier key.
Xcode offers to configure this for you when you accept the “Upgrade to recommended settings” project modernization in the issue navigator,unless your target preprocesses its Info.plist file. In that case you will need to configure this setting manually. This change is backwards-compatible to older versions of Xcode.
This change is required to make certain features work,such as On Demand Resources,if your target preprocesses its Info.plist file. (20887827)
