安装 Pod 后 FirebaseUI Pod 的 Xcode 项目构建错误“No known class method for selector 'labelColor'”

Question

I just did a pod install and got my Firebase pods updated我刚刚安装了一个 pod，并更新了我的 Firebase pod

I need the update to use a new feature from Firebase.我需要更新才能使用 Firebase 的新功能。 But I get the following error when I build my project:但是在构建项目时出现以下错误：

- (void)awakeFromNib {
  [super awakeFromNib];

  if (@available(iOS 13.0, *)) {
    self.textField.textColor = [UIColor labelColor];
    self.label.textColor = [UIColor labelColor];
  }
}

//get the following error: 
No known class method for selector 'labelColor'

another error here:这里的另一个错误：

  if (@available(iOS 13.0, *)) {
    attributedLinkText = [[NSMutableAttributedString alloc] initWithString:privacyPolicyAndTOSString
                                                                attributes:@{NSForegroundColorAttributeName: [UIColor labelColor]}];
  }
    //get the following error: 
No known class method for selector 'labelColor'

and the last one here:最后一个：

  if (@available(iOS 13, *)) {
    if (!self.authUI.interactiveDismissEnabled) {
      self.modalInPresentation = YES;
    }
  }
//get the following error: 
Property 'modalInPresentation' not found on object of type 'FUIAuthPickerViewController *'

if I comment out // these errors then the project gets build with no problem.如果我注释掉//这些错误，那么项目将毫无问题地构建。

Here is my podfile:这是我的播客文件：

# Uncomment the next line to define a global platform for your project

source 'https://github.com/CocoaPods/Specs.git'

platform :ios, '11.0'

target 'changelater' do
  # Comment the next line if you don't want to use dynamic frameworks

Any idea why I am getting this error on build?知道为什么我在构建时收到此错误吗？ and How can I fix it?我该如何解决？ I have tried many things such as:我尝试了很多事情，例如：

command+shift+k命令+shift+k
pod install --no-repo-update pod install --no-repo-update
pod update吊舱更新

note: my xcode version is 10.3.注意：我的 xcode 版本是 10.3。 It seems like I am getting this error wherever it is about if (@available(iOS 13.0, *)) .似乎我在任何地方都会收到此错误if (@available(iOS 13.0, *)) 。 In my podfile I had to force a version on other pods or else it would have caused more error anywhere related to if (@available(iOS 13.0, *))在我的 podfile 中，我必须在其他 pod 上强制使用一个版本，否则它会在与if (@available(iOS 13.0, *))相关的任何地方导致更多错误

None of these actions working...这些动作都不起作用...

Answer 1

Some iOS 13 features are only available if you use Xcode 11 to build and Xcode 10 doesn't understand them and fail to build.某些 iOS 13 功能只有在您使用 Xcode 11 构建并且 Xcode 10 不理解它们并且无法构建时才可用。

Answer 2

As @jceasarmobile mentioned if your Xcode version is 10, you should update it to the latest one and the build will work smoothly.正如@jceasarmobile 提到的，如果您的 Xcode 版本是 10，您应该将其更新到最新版本，构建将顺利进行。 Otherwise, if you want to stay with your Xcode 10 or Can't upgrade it to 11 or the latest ones, you may want to comment out these parts on the code (all occurrences where the build is failing)否则，如果您想继续使用 Xcode 10 或无法将其升级到 11 或最新版本，您可能需要在代码中注释掉这些部分（所有出现构建失败的情况）

example例子

// if (@available(iOS 13, *)) {
//    if (!self.authUI.interactiveDismissEnabled) {
//      self.modalInPresentation = YES;
//    }
//  }

This should also help you get away from the build failure.这也应该可以帮助您避免构建失败。 Of course, You should follow this only if can't upgrade it to the latest ones.当然，只有在无法将其升级到最新版本时，您才应该遵循这一点。
