Question

在我的应用中，我想发送“预定”推送通知。我使用quickblox作为推送通知服务。必须从应用程序本身创建推送通知，以便在设定的日期/时间由quickblox发送。消息的目的是发送内容可用标志，以便应用程序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。但是我找不到任何关于此的进一步信息。我尝试在sendButtonDidPress部分添加以下代码，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];

然而没有任何反应，我在NSLog中收到'UTF-8中的无效字节序列'错误。

以下是Log：

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，希望这个帮助

Answer 2

我使用了Quickblox的内容可用标志

我使用了以下来自Louwren（user3580713）问题的代码：

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：message

之后添加以下行

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

didReceiveRemoteNotification：现在，当iPhone处于睡眠状态时，会调用fetchCompletionHandler。我正在寻找一种添加内容可用标签的方法，这个问题帮助我解决了问题。谢谢。希望这有助于某人。
