问题描述
我目前在我的 Flutter iOS/Android 开发过程中遇到以下情况：
每次运行 Flutter build 时，它都会执行 pod install，安装常规 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
最后看到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!，因此我还必须将此行添加到 Onesignal Extension 目标中。
这导致我的 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。
但是由于在我的 IDE 中以调试模式运行 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 钩子中自动删除。
但由于我对 Ruby 既不太熟悉，也似乎无法在此回调中找到有关方法/属性的良好文档，因此我无法使其正常工作。
这是我迄今为止尝试过的：
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 文件？
非常感谢！
解决方法
通过正确的谷歌搜索，我设法找到了关于这个主题的单一结果：https://titanwolf.org/Network/Articles/Article?AID=18711f19-4d55-49b9-a49e-8c4652dc0262#gsc.tab=0
我从“第四，添加或删除框架到目标”中提取了他的功能
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
并且只将 if ref.name == "#{name}" 更改为 if ref.path == "#{name}"。
我还意识到我不能使用 pods_projects 中的 installer，但需要自己打开 xcodeproj 文件。这是我的最终 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,'','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，之后 flutter build 就像一个魅力。希望将来这可以为某人节省 6 小时的时间。
