ios - 没有可见的 FIRMessaging 接口(interface)声明方法 setRemoteMessageDelegate

Question

在使用 FCM tutorial for ios 实现 FCM 消息传递之后这是我在 appdelegate.m 中使用的代码

     if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
        UIUserNotificationType allNotificationTypes =
        (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
        UIUserNotificationSettings *settings =
        [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    } else {
        // iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
        UNAuthorizationOptions authOptions =
        UNAuthorizationOptionAlert
        | UNAuthorizationOptionSound
        | UNAuthorizationOptionBadge;
        [[UNUserNotificationCenter currentNotificationCenter]
         requestAuthorizationWithOptions:authOptions
         completionHandler:^(BOOL granted, NSError * _Nullable error) {
         }
         ];

        // For iOS 10 display notification (sent via APNS)
        [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];
        // For iOS 10 data message (sent via FCM)
        [[FIRMessaging messaging] setRemoteMessageDelegate:self]; // here the method is not defined // 
  #endif
    }

这里是 appdelegate.h

我尝试搜索 firemessaging delegate 堆栈上的一些人说继续更新库，它将被修复 here我不知道我做错了什么..

我也遇到了同样的错误，但最终还是构建了我的项目。检查您的 cocoapods 版本 (pod --version) 并确保它是最新的。我使用的是 2011 年的 macbook，显然仍在使用旧版(低于 1.0.0)的 cocoapods。

在更新 ruby​​、更新 cocoapods、取消注释“use_frameworks!”之后在 pod 文件中，运行“pod install”和“pod update”错误消失了。

# Uncomment this line to define a global platform for your project
# platform :ios, '8.0'
# Uncomment this line if you're using Swift
use_frameworks!

pod 'Firebase/Core'
pod 'Firebase/Messaging'

target 'myappname' do

end

target 'myappnameTests' do

end
