使用quickblox和IOS sdk实现定时推送通知

Question

在我的应用程序中，我想发送一个“预定的”推送通知。我使用quickblox作为推送通知服务。推送通知必须从应用程序本身创建，以便由quickblox在设置的日期/时间发送。消息的目的是发送一个内容可用标志，这样应用程序就可以在后台获取数据。

搜索文档，我认为这可以通过'ApplePushEvent‘来实现。然而，我找不到任何关于这方面的进一步信息。我尝试在sendButtonDidPress部分添加以下代码，以便向自己发送延迟5分钟的推送通知：

NSUInteger userID = ((QBUUser *)[_users objectAtIndex:[usersPickerView selectedRowInComponent:0]]).ID;


NSDate *date = [[NSDate alloc]init];
NSDate *fiveMinFromNow = [date dateByAddingTimeInterval:300];

QBMApplePushEvent *APEvent = [QBMApplePushEvent pushEvent];
APEvent.active = NO;
APEvent.name = @"test";
APEvent.type = QBMEventTypeOneShot;
APEvent.date = fiveMinFromNow;

APEvent.isDevelopmentEnvironment = YES;

APEvent.usersIDs = [NSString stringWithFormat:@"%d", userID];


NSString *message = @"Testing APNS!";
NSMutableDictionary *payload = [NSMutableDictionary dictionary];
NSMutableDictionary *aps = [NSMutableDictionary dictionary];
[aps setObject:@"default" forKey:QBMPushMessageSoundKey];
[aps setObject:message forKey:QBMPushMessageAlertKey];
[payload setObject:aps forKey:QBMPushMessageApsKey];


QBMPushMessage *Pushmessage = [[QBMPushMessage alloc] initWithPayload:payload];



APEvent.pushMessage = Pushmessage;

[QBMessages createEvent:APEvent delegate:self];



[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];

[messageBody resignFirstResponder];

然而，什么都没有发生，并且我在NSLog中收到了“UTF-8中的无效字节序列”错误。

以下是日志中的摘录：

Answer 1

您应该再添加一个参数并更改APEvent.type：

APEvent.pushType = QBMPushTypeAPNS;
APEvent.type = QBMEventTypeFixedDate;

试试这个，希望能帮上忙

我让content-available标志与Quickblox一起工作

我使用了Louwren (user3580713)问题中的以下代码：

NSString *message = @"Testing APNS!";
NSMutableDictionary *payload = [NSMutableDictionary dictionary];
NSMutableDictionary *aps = [NSMutableDictionary dictionary];
[aps setObject:@"default" forKey:QBMPushMessageSoundKey];
[aps setObject:message forKey:QBMPushMessageAlertKey];
[payload setObject:aps forKey:QBMPushMessageApsKey];


QBMPushMessage *Pushmessage = [[QBMPushMessage alloc] initWithPayload:payload];

并在setObject之后添加了以下行:message

[aps setObject:@"1" forKey:@"content-available"];

现在，当iPhone处于休眠状态时，会调用didReceiveRemoteNotification:fetchCompletionHandler。我正在寻找一种添加content-available标签的方法，这个问题帮我解决了这个问题。谢谢。希望这对某些人有帮助。
