Flutter:不推荐使用"UIAlertView":在iOS 9.0中第一次不推荐使用 [英] Flutter: 'UIAlertView' is deprecated: first deprecated in iOS 9.0

问题描述

我遇到以下错误:

/Users/flo/.pub-cache/hosted/pub.dartlang.org/image_picker-0.6.7+12/ios/Classes/FLTImagePickerPlugin.m:1
    49:20: warning: 'UIAlertView' is deprecated: first deprecated in iOS 9.0 - UIAlertView is deprecated.
    Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead
    [-Wdeprecated-declarations]
        [[[UIAlertView alloc] initWithTitle:@"Error"

我已经尝试做过:

flutter pub缓存修复

.pub-cache/hosted/pub.dartlang.org目录

rm the .pub-cache/hosted/pub.dartlang.org directory

rm podfile.lock和Pods文件夹

rm podfile.lock and Pods folder

但是仍然是同样的问题.有任何想法吗 ?我只发现Swift这样的问题，但与Flutter无关.

But still the same issue. Any ideas ? I only find issues like this for Swift but not related to Flutter.

推荐答案

我允许自己回答我的问题，这可能会使其他有相同问题的人受益，这是一个对我有用的简单解决方案.您无需修复/更新缓存或编辑Podfile并删除Pods文件夹.

I allow myself to answer my question which may benefit others who have the same problem, here is a simple solution that worked for me. You don't have to repair/update the cache or edit the Podfile and remove the Pods folder.

• 只需在产生错误的Pubspec上注释掉该包(在这种情况下:image_picker)
• flutter run (由于缺少软件包，您可能会遇到错误，请忽略它们)
• 取消注释行
• 再次运行，错误应该消失

• Just comment out the package on the Pubspec that generates the error (in that case: image_picker)
• flutter run (you may have errors due to the missing package, ignore them)
• Uncomment the line
• Run again and the error should be gone
