我在flutter项目中有一个网络 View 。在Web View 小部件内,我正在使用以下权限处理程序检查位置权限:
void _checkLocationPermission() async {
if (await Permission.location.request().isGranted) {
Position position = await getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
if (position == null) {
latitude = "";
longitude = "";
} else {
latitude = position.latitude.toString();
longitude = position.longitude.toString();
}
setState(() {
isPermission = true;
});
}
}
在Info.plist中,我添加了以下权限:<key>NSLocationAlwaysUsageDescription</key>
<string>Needed to access location</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>Needed to access location</string>
这是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|
target.build_configurations.each do |config|
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
'$(inherited)',
## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
'PERMISSION_LOCATION=0',
## dart: PermissionGroup.notification
'PERMISSION_NOTIFICATIONS=0'
]
end
end
end
我评论默认安装后:#post_install do |installer|
# installer.pods_project.targets.each do |target|
# flutter_additional_ios_build_settings(target)
# end
#end
然后根据权限处理程序suggestion在这些文件的末尾添加了以下行:post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
'$(inherited)',
## dart: [PermissionGroup.location, PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]
'PERMISSION_LOCATION=0',
## dart: PermissionGroup.notification
'PERMISSION_NOTIFICATIONS=0'
]
end
end
end
但是,当我在iPhone 7 Plus上运行并打开网页 View 时,未显示权限请求对话框,并且我没有位置权限!!!podfile是正确的吗?因为这是我第一次在podfile中添加内容!
最佳答案
您不需要为此的权限处理程序,此功能可通过Location plugin
checkout 其官方版本
下载并导入插件
location
添加权限
的iOS
要在iOS中使用它,您必须在Info.plist中添加此权限:
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
有关更多信息,请查看official plugin 初始化变量
String latitude_data;
String longitude_data;
bool _serviceEnabled;
当前位置函数 Future _getLocation() async {
Location location = new Location();
var _permissionGranted = await location.hasPermission();
_serviceEnabled = await location.serviceEnabled();
if (_permissionGranted != PermissionStatus.granted || !_serviceEnabled) {
///asks permission and enable location dialogs
_permissionGranted = await location.requestPermission();
_serviceEnabled = await location.requestService();
} else {
///Do something here
}
LocationData _currentPosition = await location.getLocation();
longitude_data=_currentPosition.longitude.toString();
latitude_data=_currentPosition.latitude.toString();
///if you want you can save data to sharedPrefrence
SharedPrefrence().setLatitude(_currentPosition.latitude.toString());
SharedPrefrence().setLongitude(_currentPosition.longitude.toString());
}
然后从手机上卸载该应用,运行干净然后再次运行
