- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在与Firebase一起在应用程序上启用推送通知。遵循Firebase的准则
NSString *fcmToken = [FIRMessaging messaging].FCMToken;
这行代码导致生成错误:FIRMessaging对象上找不到FCMToken。
#import <Firebase/Firebase.h>
#import <FirebaseAnalytics/FirebaseAnalytics.h>
#import <FirebaseInstanceID/FirebaseInstanceID.h>
#import <UserNotifications/UserNotifications.h>
#import <FirebaseMessaging/FIRMessaging.h>
我还添加了:UNUserNotificationCenterDelegate,FIRMessagingDelegate
@interface myAppDelegate : NSObject <UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate> {
我还尝试了以下方法来获取 token :
- (void)tokenRefreshNotification:(NSNotification *)notification {
NSString *tokenId = [[FIRInstanceID instanceID] token];
NSLog(@"FCM registration token: %@", tokenId);
}
但是生成的 token 始终等于null。
// this is always getting null value
- (void)tokenRefreshNotification:(NSNotification *)notification {
NSString *tokenId = [[FIRInstanceID instanceID] token];
[self connectToFcm];
[tokenId retain];
}
- (void)connectToFcm {
if(gotConnected)
{
return;
}
[[FIRMessaging messaging] connectWithCompletion:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(@"Unable to connect to FCM. %@", error);
} else {
gotConnected = true;
NSLog(@"Connected to FCM.");
}
}];
}
//this is never getting called
- (void)messaging:(nonnull FIRMessaging *)messaging didRefreshRegistrationToken:(nonnull NSString *)fcmToken
{
NSLog(@"didRefreshRegistrationToken fcmToken: %@", fcmToken);
}

{

[[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) {}];
[[UIApplication sharedApplication] registerForRemoteNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:) name:kFIRInstanceIDTokenRefreshNotification object:nil];
}
我还尝试了以下方法来获取 token :
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
[[FIRInstanceID instanceID] setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeProd];
NSLog(@"deviceToken %@", deviceToken);
NSString * token = [NSString stringWithFormat:@"%@", deviceToken];
//Format token as you need:
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
NSLog(@"token %@", token);
tokenId = token;
[self connectToFcm];
}
当我尝试在Firebase上使用此 token 时,我得到了无效的 token ,而我得到了一个示例 token :
7da8917e48dd7d09c7c0e537abd08fcab1778be73738052ef70e0f6e27a7015e
最佳答案
您是否在iOS 10或更高版本上运行?如果是,则应设置remoteMessageDelegate
。
请看下面的代码:
[FIRApp configure];
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].delegate = self;
// For iOS 10 data message (sent via FCM)
[FIRMessaging messaging].remoteMessageDelegate = self;
#endif
