未收到CloudKit推送通知
未收到CloudKit推送通知
提问于 2014-06-17 01:12:58
我正在写一个使用CloudKit的小应用程序。由于某些原因，当有新的记录匹配查询时，应用程序不会收到任何通知。有没有人能让这个特性起作用？
我在应用程序中创建新记录，也在CloudKit仪表板中创建新记录。记录非常简单，只有一个整型字段。
创建一条记录：
CKRecord *record = [[CKRecord alloc] initWithRecordType:kSISCloudKitRecordTypeTest];
record[@"value"] = @1;
[self.publicDatabase saveRecord:record completionHandler:^(CKRecord *record, NSError *error)
{
// this call succeeds, no error.
}];注册接收通知：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[application registerForRemoteNotifications];
}创建订阅：
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"value = 1"];
CKSubscription *subscription = [[CKSubscription alloc]
initWithRecordType:kSISCloudKitRecordTypeTest
predicate:predicate
options:CKSubscriptionOptionsFiresOnRecordCreation];
CKNotificationInfo *notificationInfo = [CKNotificationInfo new];
notificationInfo.alertLocalizationKey = @"LOCAL_NOTIFICATION_KEY";
notificationInfo.soundName = @"Party.aiff";
notificationInfo.shouldBadge = YES;
subscription.notificationInfo = notificationInfo;
[self.publicDatabase saveSubscription:subscription
completionHandler:^(CKSubscription *subscription, NSError *error)
{
// this succeeds as well, at least the 1st time I run it.
// on subsequent calls it returns an error "duplicate subscription", which is OK by me.
}在运行上述代码并在仪表板中创建新记录后，我希望调用此应用程序委托方法：
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
CKNotification *cloudKitNotification = [CKNotification notificationFromRemoteNotificationDictionary:userInfo];
NSLog(@"cloudKitNotification: %@", cloudKitNotification);
}但是，它从未被调用过。

我现在收到从Beta 3开始的通知：
{
aps = {
};
ck = {
ce = 2;
cid = "iCloud.com.domain.App";
nid = "0b3ae470-d2c0-4f35-a817-12a899ee5964";
qry = {
dbs = 2;
fo = 1;
rid = 88aee11ca88d4ecc45bf57c898b360c8e7e3d8bb;
zid = "_defaultZone";
zoid = "_defaultOwner";
};
};
}此外，CKNotificationInfo上有一个shouldSendContentAvailable属性，可以在后台接收通知-这似乎也可以工作(从Beta4开始)。
