【中文标题】在 post_install Podfile 挂钩中删除链接的 Pods_framework【英文标题】:Removing linked Pods_framework in post_install Podfile hook 【发布时间】:2021-04-09 02:57:59 【问题描述】:我目前在flutter ios/android开发过程中遇到以下情况:
每次flutter build
运行时,它都会执行pod install
,它会安装常规的 Flutter Podfile
# Uncomment this line to define a global platform for your project
platform :ios, '10.0'
# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'false'
project 'Runner',
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
def parse_KV_file(file, separator='=')
file_abs_path = File.expand_path(file)
if !File.exists? file_abs_path
return [];
end
generated_key_values =
skip_line_start_symbols = ["#", "/"]
File.foreach(file_abs_path) do |line|
next if skip_line_start_symbols.any? |symbol| line =~ /^\s*#symbol/
plugin = line.split(pattern=separator)
if plugin.length == 2
podname = plugin[0].strip()
path = plugin[1].strip()
podpath = File.expand_path("#path", file_abs_path)
generated_key_values[podname] = podpath
else
puts "Invalid plugin specification: #line"
end
end
generated_key_values
end
target 'Runner' do
use_frameworks!
use_modular_headers!
# Flutter Pod
copied_flutter_dir = File.join(__dir__, 'Flutter')
copied_framework_path = File.join(copied_flutter_dir, 'Flutter.framework')
copied_podspec_path = File.join(copied_flutter_dir, 'Flutter.podspec')
unless File.exist?(copied_framework_path) && File.exist?(copied_podspec_path)
# Copy Flutter.framework and Flutter.podspec to Flutter/ to have something to link against if the xcode backend script has not run yet.
# That script will copy the correct debug/profile/release version of the framework based on the currently selected Xcode configuration.
# CocoaPods will not embed the framework on pod install (before any build phases can generate) if the dylib does not exist.
generated_xcode_build_settings_path = File.join(copied_flutter_dir, 'Generated.xcconfig')
unless File.exist?(generated_xcode_build_settings_path)
raise "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
generated_xcode_build_settings = parse_KV_file(generated_xcode_build_settings_path)
cached_framework_dir = generated_xcode_build_settings['FLUTTER_FRAMEWORK_DIR'];
unless File.exist?(copied_framework_path)
FileUtils.cp_r(File.join(cached_framework_dir, 'Flutter.framework'), copied_flutter_dir)
end
unless File.exist?(copied_podspec_path)
FileUtils.cp(File.join(cached_framework_dir, 'Flutter.podspec'), copied_flutter_dir)
end
end
# Keep pod path relative so it can be checked into Podfile.lock.
pod 'Flutter', :path => 'Flutter'
# Plugin Pods
# Prepare symlinks folder. We use symlinks to avoid having Podfile.lock
# referring to absolute paths on developers' machines.
system('rm -rf .symlinks')
system('mkdir -p .symlinks/plugins')
plugin_pods = parse_KV_file('../.flutter-plugins')
plugin_pods.each do |name, path|
symlink = File.join('.symlinks', 'plugins', name)
File.symlink(path, symlink)
pod name, :path => File.join(symlink, 'ios')
end
end
target 'OneSignalNotificationServiceExtension' do
use_frameworks!
pod 'OneSignal', '>= 2.9.3', '< 3.0'
end
如在最后看到的在我的应用程序中启用 OneSignal 推送通知,我添加了 OneSignalNotificationServiceExtension。由于 Flutter Runner 需要 use_frameworks!
,所以我也必须将此行添加到 OneSignal Extension 目标中。
这会导致在我的 OneSignal 目标(“Pods_OneSignalNotificationServiceExtension.framework”)上的“常规”>“框架和库”下包含以下文件: wrongly linked file
但是这个文件可能不存在所以构建失败。
如果我从 XCode 中手动删除此文件,则构建工作正常。
但是由于从我的 IDE 以调试模式运行 Flutter 再次运行 pod install
,我无法删除此链接,所以我的想法是在 Podfile 内的 post_install
挂钩中自动删除。
但由于我对 Ruby 不是很熟悉,也似乎无法在此回调中找到有关方法/属性的良好文档,所以我无法让它工作。
这是我迄今为止尝试过的一些方法:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
if target.name == 'Pods-OneSignalNotificationServiceExtension'
all_filerefs = installer.pods_project.files
all_filerefs.each do |fileref|
#puts(fileref.path)
if fileref.path.end_with? "Pods_OneSignalNotificationServiceExtension.framework"
puts("Found Pods_OneSignalNotificationServiceExtension.framework fileref.")
build_phase = target.frameworks_build_phase
#puts("Determining if build phase needs correction.")
#all_filerefs.delete(fileref)
build_phase.remove_file_reference(fileref)
puts("Removing Pods_OneSignalNotificationServiceExtension.framework from OneSignalNotificationServiceExtension target")
end
end
end
end
end
但是从all_filerefs
和build_phase.remove_file_reference
中删除它都不是很有效。有谁知道我如何从 XCode 的“框架和库”部分访问链接文件以及如何删除所述 .framework-file?
非常感谢!

【参考方案1】:通过正确的谷歌搜索,我设法找到了关于此主题的单个结果:https://titanwolf.org/Network/Articles/Article?AID=18711f19-4d55-49b9-a49e-8c4652dc0262#gsc.tab=0
我已经从“第四,添加或删除框架到目标”中获取了他的功能
def updateCustomFramework(project,target,path,name,command)
# Get useful variables
frameworks_group = project.groups.find |group| group.display_name == 'Frameworks'
frameworks_build_phase = target.build_phases.find |build_phase| build_phase.to_s == 'FrameworksBuildPhase'
embed_frameworks_build_phase = nil
target.build_phases.each do |phase|
if phase.display_name == 'Embed Frameworks'
embed_frameworks_build_phase = phase
end
# puts phase
end
if command == :add
# Add new "Embed Frameworks" build phase to target
if embed_frameworks_build_phase.nil?
embed_frameworks_build_phase = project.new(Xcodeproj::Project::Object::PBXCopyFilesBuildPhase)
embed_frameworks_build_phase.name = 'Embed Frameworks'
embed_frameworks_build_phase.symbol_dst_subfolder_spec = :frameworks
target.build_phases << embed_frameworks_build_phase
end
# Add framework search path to target
['Debug', 'Release'].each do |config|
paths = ['$(inherited)', path]
orgpath = target.build_settings(config)['FRAMEWORK_SEARCH_PATHS']
if orgpath.nil?
puts "path is empty----------"
target.build_settings(config)['FRAMEWORK_SEARCH_PATHS'] = paths
else
puts "path is not empty----------"
paths.each do |p|
if !orgpath.include?(p)
orgpath << p
end
end
end
end
# Add framework to target as "Embedded Frameworks"
framework_ref = frameworks_group.new_file("#path#name")
exsit = false
embed_frameworks_build_phase.files_references.each do |ref|
if ref.name = name
exsit = true
end
end
if !exsit
build_file = embed_frameworks_build_phase.add_file_reference(framework_ref)
frameworks_build_phase.add_file_reference(framework_ref)
build_file.settings = 'ATTRIBUTES' => ['CodeSignOnCopy']
end
else
frameworks_build_phase.files_references.each do |ref|
#puts(ref.path)
if ref.path == "#name"
puts "delete #name"
frameworks_build_phase.remove_file_reference(ref)
#embed_frameworks_build_phase.remove_file_reference(ref)
break
end
end
end
end
并且仅将if ref.name == "#name"
更改为if ref.path == "#name"
。
我还意识到我不能使用installer
中的pods_projects
,但需要自己打开xcodeproj 文件。这是我最终的post_install
脚本:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
project_path = 'Runner.xcodeproj'
project = Xcodeproj::Project.open(project_path) # Opening the Runner.xcodeproj in the same folder as the Podfile
project.targets.each do |target|
if target.name == "OneSignalNotificationServiceExtension" # Find the OneSignal Target
updateCustomFramework(project, target, '', 'Pods_OneSignalNotificationServiceExtension.framework', ':remove') # Run the function on the target with the framework name
end
end
project.save() # Don't forget to save the project, or the changes won't stay
end
之后flutter clean
是必要的,然后flutter build
就像一个魅力。希望将来这可以为某人节省 6 个小时的时间。
