如果我的应用程序在前台或后台运行，则工作正常。我收到通知并将其保存在本地数据库中。但是，如果应用程序从后台终止，它将收到远程通知，但不会调用以下方法。问题是如果我点击任何一个通知，只有该通知将保存在本地数据库中。
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
{
[PFPush handlePush:userInfo];
NSLog(@"Received notification: %@", userInfo);
NSString *alertString = [[userInfo objectForKey:@"aps"]valueForKey:@"alert"];
NSLog(@"%@",alertString);
NSString *msgType = [userInfo objectForKey:@"messageType"];
NSString *senderId = [userInfo objectForKey:@"senderId"];
NSString *receverId = [userInfo objectForKey:@"receverId"];
NSString *msg = [userInfo objectForKey:@"message"];
NSString *timeStr = [userInfo objectForKey:@"Time"];
NSLog(@"msg type%@ senderId %@ receverId %@ message %@",msgType,senderId,receverId,msg);
if ([AppDelegate isNetworkReachable]){
if ([msgType isEqualToString:@"CHAT"]) {
Chatmessage *Cmsg=[[Chatmessage alloc]init];
Cmsg.chat_date =timeStr;
Cmsg.chat_image =@"";
Cmsg.chat_message = msg;
Cmsg.chat_Receiver_Id = receverId;
Cmsg.chat_Sender_Id = senderId;
NSLog(@"recid%@",Cmsg.chat_Receiver_Id);
NSMutableArray *arryMsg = [[NSMutableArray alloc]init];
arryMsg = [[DBModelNew database]getChatMessageBasedOnTime:receverId SenId:senderId time_stamp:timeStr message:msg];
if (arryMsg.count == 0) {
[[DBModelNew database]insertmsg:Cmsg];
}
[[NSNotificationCenter defaultCenter]postNotificationName:@"receivedmessage" object:nil];
chatHistory *chatObj = [[chatHistory alloc]init];
chatObj.chat_meta_id = [NSString stringWithFormat:@"%@",senderId];
chatObj.last_send_message = msg;
NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init];
dateFormatter.dateFormat = @"yyyy-MM-dd HH:mm:ss";
NSString *str=[dateFormatter stringFromDate:[NSDate date]];
chatObj.last_time_stamp = [self dateformat:str];
PFQuery *query = [PFUser query];
[query whereKey:@"objectId" equalTo:senderId];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
for (NSDictionary *dict in objects) {
[[dict objectForKey:@"ProfilePic"] getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
if (data) {
UIImage *image = [UIImage imageWithData:data];
if (image) {
chatObj.fndimage = image;
chatObj.name = [dict objectForKey:@"name"];
[[DBModelNew database]insertChat:chatObj];
[[NSNotificationCenter defaultCenter]postNotificationName:@"receivedNewMessage" object:nil];
}
}
}
}];
}
}
}];
}
}
}
最佳答案
从Apple文档中，如果用户硬关闭应用程序，则不会调用该方法。
此外，如果您启用了远程通知后台模式，
系统启动您的应用程序(或将其从挂起状态唤醒)
并在远程通知时将其置于后台状态
到达。 但是，如果出现以下情况，系统不会自动启动您的应用
用户已强制退出它。 在这种情况下，用户必须重新启动
您的应用或在系统尝试启动之前重新启动设备
再次自动运行您的应用。
