使用未声明的标识符'FIRMessaging'

Question

我正在尝试遵循这里的指南:https://firebase.google.com/docs/cloud-messaging/ios/send-image

我在Xcode中创建一个新项目，并打开我的应用程序项目，导航到File>添加包，然后输入https://github.com/firebase/firebase-ios-sdk。在我去New>目标比;通知服务扩展(将此新目标嵌入到原始目标中)并粘贴在NotificationService.m:

中

@interface NotificationService ()
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@end
@implementation NotificationService
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];

// Modify the notification content here...
self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]", self.bestAttemptContent.title];

// Call FIRMessaging extension helper API.
[[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent
withContentHandler:contentHandler];

self.contentHandler(self.bestAttemptContent);
}
- (void)serviceExtensionTimeWillExpire {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
self.contentHandler(self.bestAttemptContent);
}
@end

我现在得到Use of undeclared identifier 'FIRMessaging' in NotificationService.m。我忘了什么?

Answer 1

在Podfile中，使用pod文件代码

platform :ios, '11.0'
def same_pods
pod 'Firebase/Messaging'
end
target 'Project' do
use_frameworks!
pod 'Firebase', "~> 7.0"
target 'NotificationServiceExt' do
inherit! :search_paths
end

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64 i386"
end
end
installer.generated_projects.each do |project|
project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
end
end
end
end

end

安装pod文件和NotificationService文件

#import "NotificationService.h"
@import Firebase;
@interface NotificationService ()
@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;
@end
@implementation NotificationService
- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
self.contentHandler = contentHandler;
self.bestAttemptContent = [request.content mutableCopy];
// Modify the notification content here as you wish
self.bestAttemptContent.title = [NSString stringWithFormat:@"%@",
self.bestAttemptContent.title];
// Call FIRMessaging extension helper API.
[[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent withContentHandler:contentHandler];


}
- (void)serviceExtensionTimeWillExpire {
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
self.contentHandler(self.bestAttemptContent);
}
@end
