在尝试了几件事但都没有成功之后，我请求帮助。
1-问题
即使在iOS模拟器、Android模拟器和物理设备上一切正常，我也无法在物理iPhone上部署我的flutter应用程序(自动签名(。。。

2-我尝试过的：
- 我试过了
打开ios/Runner.xcworkspace
并且在Xcode中选择文件>工作区设置>quot；遗留构建"；模式(在另一个stackoverflow线程上找到(但它似乎没有改变任何事情，并且在来自android工作室终端的Xcode注释中；移动到新的构建模式"？
- 也尝试过
打开ios/Runner.xcodeproj
file>项目设置>旧版生成模式。。。也不起作用。。。
我很失望，作为一名安卓开发人员(以及最近的Flutter开发人员(，我真的不知道iOS方面的
谢谢你的帮助！：(
这是我的整个podfile:：
# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'
# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
# post_install do |installer|
# installer.pods_project.targets.each do |target|
# flutter_additional_ios_build_settings(target)
# end
# end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
# config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
end
end
end
在引入第二个目标构建后，我也遇到了同样的问题。对我来说，这是由于错误地将info.plist和Runner-copy.app包含在创建循环引用的Xcode Target Membership中造成的。*info.plist和*.app不应处于任何目标成员身份中。
这与Podfile中的Targets无关。
要创建第二个Xcode目标，请在Xcode中打开项目并复制Runner目标。这里有一个关于在Xcode中创建Targets的小教程-https://andersongusmao.medium.com/xcode-targets-with-multiples-build-configuration-90a575ddc687.
完成后，您需要选择项目中每个文件的成员身份。大多数人应该是两个/所有目标的成员。如果您有一个特定于一个目标的plist(例如，一个的生产密钥和另一个的开发密钥(，则它们应该仅是关联目标的成员。
如上所述，*info.plist和*.app不应处于任何目标成员资格中。
