Question

我正在尝试使geolocator 2.1.0插件与我的ios xcode项目一起使用，并在运行pod install之后得到以下2个错误提示

类型'UIApplication'没有成员'openSettingsURLString' 和 'OpenExternalURLOptionsKey'不是'UIApplication'的成员类型

已采取的步骤。

我打开一个新的Flutter项目（无论是否选中“ Swift支持”，都会发生错误）-获取默认应用。
仅使用-geolocator：^ 2.1.0
运行“ flutter pacakges get”和“ pod install”。所有库均在AndroidStudio和XCode 9.2中显示。

希望我缺少一些简单的东西。感谢您的高级帮助。

Podfile看起来像这样

（我已经用'config.build_settings ['SWIFT_VERSION'] ='4.1''更新了文件。

# 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'

def parse_KV_file(file, separator='=')
  file_abs_path = File.expand_path(file)
  if !File.exists? file_abs_path
    return [];
  end
  pods_ary = []
  skip_line_start_symbols = ["#", "/"]
  File.foreach(file_abs_path) { |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)
        pods_ary.push({:name => podname, :path => podpath});
      else
        puts "Invalid plugin specification: #{line}"
      end
  }
  return pods_ary
end

target 'Runner' do
  # 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')

  # Flutter Pods
  generated_xcode_build_settings = parse_KV_file('./Flutter/Generated.xcconfig')
  if generated_xcode_build_settings.empty?
    puts "Generated.xcconfig must exist. If you're running pod install manually, make sure flutter packages get is executed first."
  end
  generated_xcode_build_settings.map { |p|
    if p[:name] == 'FLUTTER_FRAMEWORK_DIR'
      symlink = File.join('.symlinks', 'flutter')
      File.symlink(File.dirname(p[:path]), symlink)
      pod 'Flutter', :path => File.join(symlink, File.basename(p[:path]))
    end
  }

  # Plugin Pods
  plugin_pods = parse_KV_file('../.flutter-plugins')
  plugin_pods.map { |p|
    symlink = File.join('.symlinks', 'plugins', p[:name])
    File.symlink(p[:path], symlink)
    pod p[:name], :path => File.join(symlink, 'ios')
  }
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
      config.build_settings['SWIFT_VERSION'] = '4.1'
    end
  end
end

Answer 1

在use_frameworks!的目标运行器中添加(YOUR_PROJECT)/ios/Podfile。

target 'Runner' do
  use_frameworks!  # required by Geolocator

  # 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')

地理定位器的旧版本，例如^1.6.3，要求将SWIFT_VERSION设置为4.0或4.1。

但是geolocator版本2.1.0使用permission_handler版本2.1.1，它需要SWIFT_VERSION 4.2。

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '4.2'  # required by Geolocator
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

我能够使用Flutter geolocator和Xcode 2.1.0在我的应用中成功构建并使用0.11.9版本10.1。

Flutter：类型“ UIApplication”没有成员“ openSettingsURLString”
