【问题描述】：
我的应用程序已启动，但在某些设备上崩溃了，但我也有混乱的日志，这令人困惑，他们建议它在此功能中崩溃。
该函数在应用启动时调用（它会立即崩溃） 任何帮助将不胜感激
- (void) setupForPushNotifications {
UIMutableUserNotificationAction *readAction = [[UIMutableUserNotificationAction alloc] init];
readAction.identifier = @"READ_IDENTIFIER";
readAction.title = @"Read";
readAction.activationMode = UIUserNotificationActivationModeForeground;
readAction.destructive = NO;
readAction.authenticationRequired = YES;
UIMutableUserNotificationAction *ignoreAction = [[UIMutableUserNotificationAction alloc] init];
ignoreAction.identifier = @"IGNORE_IDENTIFIER";
ignoreAction.title = @"Ignore";
ignoreAction.activationMode = UIUserNotificationActivationModeBackground;
ignoreAction.destructive = NO;
ignoreAction.authenticationRequired = NO;
UIMutableUserNotificationAction *deleteAction = [[UIMutableUserNotificationAction alloc] init];
deleteAction.identifier = @"DELETE_IDENTIFIER";
deleteAction.title = @"Delete";
deleteAction.activationMode = UIUserNotificationActivationModeForeground;
deleteAction.destructive = YES;
deleteAction.authenticationRequired = YES;
UIMutableUserNotificationCategory *messageCategory = [[UIMutableUserNotificationCategory alloc] init];
messageCategory.identifier = @"MESSAGE_CATEGORY";
[messageCategory setActions:@[readAction, ignoreAction, deleteAction] forContext:UIUserNotificationActionContextDefault];
[messageCategory setActions:@[readAction, deleteAction] forContext:UIUserNotificationActionContextMinimal];
NSSet *categories = [NSSet setWithObject:messageCategory];
UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:categories];
[[UIApplication sharedApplication] registerForRemoteNotifications];
[[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
}

【问题讨论】：
-
是否有运行 iOS
-
看起来它在告诉你
readAction是nil。 -
是的，你认为这可能与 ios 版本有关？
-
readAction 它显然不是 nil，怎么可能只有少数设备而不是所有设备都是 nil？
