Xamarin Object Sharpie Obj-C Библиотека Binding, зачем выводить огромный файл?
Я пытаюсь привязать часть Heatmap к утилитам Google Maps для iOS.
https://github.com/googlemaps/google-maps-ios-utils
2: CreateMakefile & Выполнить команду make
XBUILD=/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild
PROJECT_ROOT=./GoogleMapiOSHeatmapUtility
PROJECT=./GoogleMapiOSHeatmapUtility.xcodeproj
TARGET=GoogleMapiOSHeatmapUtility
all: lib$(TARGET).a
lib$(TARGET)-i386.a:
$(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphonesimulator -configuration Release clean build
-mv ./build/Release-iphonesimulator/lib$(TARGET).a $@
lib$(TARGET)-armv7.a:
$(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphoneos -arch armv7 -configuration Release clean build
-mv ./build/Release-iphoneos/lib$(TARGET).a $@
lib$(TARGET)-arm64.a:
$(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphoneos -arch arm64 -configuration Release clean build
-mv ./build/Release-iphoneos/lib$(TARGET).a $@
lib$(TARGET).a: lib$(TARGET)-i386.a lib$(TARGET)-armv7.a lib$(TARGET)-arm64.a
xcrun -sdk iphoneos lipo -create -output $@ $^
clean:
-rm -f *.a *.dll
3: добавить 「.a」 File BindingProject
4: создавать файлы ApiDefinitions & StructsAndEnums
Выполнить команду
sharpie bind --output=GoogleMapiOSHeatmapUtility --namespace=GoogleMapiOSHeatmapUtility --sdk=iphoneos11.1 ./GoogleMapiOSHeatmapUtility/*.h
Результат

Binding Analysis:
Automated binding is complete, but there are a few APIs which have been flagged with [Verify] attributes. While the entire binding should be audited for best API design practices, look more closely at APIs
with the following Verify attribute hints:
ConstantsInterfaceAssociation (205 instances):
There's no foolproof way to determine with which Objective-C interface an extern variable declaration may be associated. Instances of these are bound as [Field] properties in a partial interface into a
nearby concrete interface to produce a more intuitive API, possibly eliminating the 'Constants' interface altogether.
MethodToProperty (201 instances):
An Objective-C method was bound as a C# property due to convention such as taking no parameters and returning a value (non-void return). Often methods like these should be bound as properties to surface a
nicer API, but sometimes false-positives can occur and the binding should actually be a method.
StronglyTypedNSArray (45 instances):
A native NSArray* was bound as NSObject[]. It might be possible to more strongly type the array in the binding based on expectations set through API documentation (e.g. comments in the header file) or by
examining the array contents through testing. For example, an NSArray* containing only NSNumber* instances can be bound as NSNumber[] instead of NSObject[].
PlatformInvoke (3177 instances):
In general P/Invoke bindings are not as correct or complete as Objective-C bindings (at least currently). You may need to fix up the library name (it defaults to '__Internal') and return/parameter types
manually to conform to C calling conventionsfor the target platform. You may find you don't even want to expose the C API in your binding, but if you do, you'll probably also want to relocate the
definition to a more appropriate class and expose a stronger type-safe wrapper. For P/Invoke guidance, see http://www.mono-project.com/docs/advanced/pinvoke/.
InferredFromMemberPrefix (30 instances):
The name of this originally anonymous declaration was taken from a common prefix of its members.
Once you have verified a Verify attribute, you should remove it from the binding source code. The presence of Verify attributes intentionally cause build failures.
For more information about the Verify attribute hints above, consult the Objective Sharpie documentation by running 'sharpie docs' or visiting the following URL:

Done.
После выполнения команды sharpie bind создаются файлы ApiDefinitions.cs и StructsAndEnums.cs, но оба файла содержат код, содержащий более 20000 строк и более 3000 ошибок.
Почему будет создан огромный файл, если используются 14 заголовочных файлов, и ни один из них не соответствует 100 строкам?
Я только начал Xamarin, и я немного борюсь здесь. Есть причина, почему тепловые карты должны использоваться абсолютно.
пожалуйста, помогите мне

Кажется, что эта проблема идет с последней версией Sharpie(я сделал библиотеку переплетов раньше, и она работала нормально).
Полезна только часть огромного файла (в конце файла), вы можете удалить бесполезный код.
Более того, я предлагаю вам создать его через CocoaPods, если этот проект зарегистрирован в нем.
