我正在聊天应用程序,因为我用UITableView
聊天屏幕。在每一个聊天泡泡用户的个人资料图片在那里,现在我的问题是当一个新的消息来或我发送新的消息整个tableView
重新加载与聊天气泡中的图像也,我想停止它,任何人都可以帮我找出它? 我的代码是:停止重新加载UItableView一次又一次在Iphone
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView == self.chatTableView)
{
NSString *cellID;
if([[((UUMessageFrame *)(self.chatModel.dataSource[indexPath.row])) message] from] == UUMessageFromMe)
{
cellID = @"outgoing_cell";
}
else
{
cellID = @"incoming_cell";
}
//commented by jigar
// UUMessageCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
// UUMessageCell *cell = [tableView];
UUMessageCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[UUMessageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
cell.delegate = self;
if ([cellID isEqualToString:@"outgoing_cell"])
{
// cell.recognizer.numberOfTapsRequired
[cell.recognizer addTarget:self action:@selector(longPress:)];
}
}
[cell setMessageFrame:self.chatModel.dataSource[indexPath.row]];
NSLog(@" text message is : %@",[cell.btnContent titleForState:UIControlStateNormal]);
cell.btnContent.tag = indexPath.row;
return cell;
}
else
{
NSString *cellIdentifier;/* = isOutgoingMessage ? self.outgoingCellIdentifier : self.incomingCellIdentifier;*/
if ([[self.arrTableData objectAtIndex:indexPath.row] isKindOfClass:[OTRVoice class]])
{
OTRVoice *voice = (OTRVoice *)[self.arrTableData objectAtIndex:indexPath.row];
if(![voice.fk_Tripper isEqualToString:appDelegate.account.uniqueId])
{
cellIdentifier = self.incomingCellIdentifier;
}
else
{
cellIdentifier = self.outgoingCellIdentifier;
}
}
else{
cellIdentifier = self.outgoingCellIdentifier;
}
@try
{
VoiceTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
cell.avatarImage.clipsToBounds = YES;
cell.avatarImage.layer.cornerRadius = cell.avatarImage.bounds.size.width/2.0;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
tableview.separatorStyle = UITableViewCellSeparatorStyleNone;
cell.circular_ProgressView.frame = CGRectMake(cell.btnPlay.frame.origin.x-2, cell.btnPlay.frame.origin.y, 26, 26);
[self configureCell:cell atIndexPath:indexPath];
cell.tag = indexPath.row +10000;
return cell;
