目录结构是这样的
外层’Makefile’是：
THEOS_DEVICE_IP = localhost
THEOS_DEVICE_PORT = 5555
ARCHS = armv7 arm64
TARGET = iphone:latest:7.0
include $(THEOS)/makefiles/common.mk
TWEAK_NAME = VolumeControl
VolumeControl_FILES = $(wildcard src/*.xm)
VolumeControl_FRAMEWORKS = UIKit CoreGraphics AudioToolbox AVFoundation
VolumeControl_PRIVATE_FRAMEWORKS = MediaRemote
VolumeControl_EXTRA_FRAMEWORKS += Cephei
VolumeControl += -Wl,-segalign,4000
VolumeControl_CFLAGS = -Wno-deprecated -Wno-deprecated-declarations
include $(THEOS_MAKE_PATH)/tweak.mk
after-install::
install.exec "killall -9 SpringBoard"
SUBPROJECTS += Preferences
include $(THEOS_MAKE_PATH)/aggregate.mk
'Preferences’文件夹下的’Makefile’是：
THEOS_DEVICE_IP = localhost
include $(THEOS)/makefiles/common.mk
BUNDLE_NAME = VolumeControl
VolumeControl_FILES = XXXRootListController.m
VolumeControl_INSTALL_PATH = /Library/PreferenceBundles
VolumeControl_FRAMEWORKS = UIKit
VolumeControl_PRIVATE_FRAMEWORKS = Preferences
include $(THEOS_MAKE_PATH)/bundle.mk
internal-stage::
$(ECHO_NOTHING)mkdir -p $(THEOS_STAGING_DIR)/Library/PreferenceLoader/Preferences$(ECHO_END)
$(ECHO_NOTHING)cp entry.plist $(THEOS_STAGING_DIR)/Library/PreferenceLoader/Preferences/VolumeControl.plist$(ECHO_END)
然后在iOS 11上可以正常编译使用，但是再iOS 10和iOS 9上可以编译，但是再设置里面进入后确显示’There was an error loading the preference bundle for’，第一次做插件，希望得到大家帮助(Cydia open source 部分项目也看过，实在找不到原因)，求教。
