Ich habe Comet Chat-Funktionalität in meiner Anwendung integriert. Ich verwende eine benutzerdefinierte Benutzeroberfläche für den Gruppen- und OneOnOne-Chat. Es läuft alles gut, aber das Problem ist, dass meine Anwendung nicht mehr reagiert, wenn ich zu meinem Gruppen-Chat-Bildschirm gehe. Es reagiert nicht mehr, wenn ich meinen Tisch scrolle.Comet Chat iOS nicht reagierende UI Problem
Ich hatte Versand Funktionalität in meinem CellforRowatIndexPath zum Abrufen der Bilder Link und zeigt sie. Dafür verwende ich SdWebImage Framework.
Hier ist mein Code:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = @"chatroomchatviewcell";
chatViewCell = [chatTable dequeueReusableCellWithIdentifier:cellIdentifier];
if (chatViewCell == nil) {
chatViewCell = [[ChatRoomChatViewCellSDK alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
else {
dispatch_queue_t concurrentQueue1 = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(concurrentQueue1, ^{
for (UIView *view in chatViewCell.contentView.subviews) {
[view removeFromSuperview];
}
});
}

Hier bin ich Umsetzung Chat-Funktion für diese müssen wir die Chat-Nachrichten auf dem Bildschirm aktualisieren und für das ich verwende NsPostNotifictaionCenter. Ich lade meine Tabelle auch mit dem Versand neu, um das Problem der nicht reagierenden Benutzeroberfläche zu vermeiden. Hier poste ich den Code:
- (void)chatRoomMessageUpdateNotifier: (NSNotification *)notification {
dispatch_queue_t concurrentQueue1 = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(concurrentQueue1, ^{
if ([[[notification userInfo] objectForKey:@"TAG"] isEqualToString:@"0"]) {
messageArray = [NSMutableArray new];
[messageArray removeAllObjects];
messageArray = [[notification userInfo] objectForKey:@"data"];
if ([messageArray count] > 0) {
dispatch_async(dispatch_get_main_queue(), ^{
[chatTable reloadData];
});
}
}
});
}
Ich weiß nicht, was ich falsch mache. Das Hauptproblem hier ist, dass meine Benutzeroberfläche nicht mehr reagiert. Alle Ideen sind herzlich willkommen.
Ich habe versucht, ur-code, aber es immer noch einfrieren .. entfernt alle abteilungen. Gefolgt ur code, aber es immer noch happening – Prakash
Vielen Dank für Ihre Hilfe, Mike D! Wenn Sie ein Unternehmen sind und ein Stack Overflow-Konto zwischen Mitarbeitern teilen, ist es besser, wenn Sie über individuelle Konten verfügen. Das liegt hauptsächlich daran, dass wir Fragen und Antworten bevorzugen, die nicht unterschrieben werden müssen - dieses Material wird oft von Redakteuren zugeschnitten (siehe meine Änderungen). – halfer
