我有一个UITableView
,其中包含一个FBProfilePictureView
和一个UILable
,
我的问题是,当用户滚动图片时会重建其自身,并且花一些时间来显示其自身的图像,我想知道如何一次创建FBProfilePictureView
,然后在用户滚动时不会再次自行构建。
这是我的代码:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
Messages *msg = [messages objectAtIndex:indexPath.row];
NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
NSData *encodedDataObject = [def objectForKey:@"myUser"];
User *user = (User *)[NSKeyedUnarchiver unarchiveObjectWithData: encodedDataObject];
if(![msg.wrote_id isEqualToString:user.fid])
{
NSString *idToImage = [self getOtherUserId];
NSString *CellIdentifier = @"Cell";
ChatWindowCell *cell = nil;
cell = (ChatWindowCell *)[tableChat dequeueReusableCellWithIdentifier:CellIdentifier];
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"ChatWindowCell" owner:nil options:nil];
for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[ChatWindowCell class]])
{
cell = (ChatWindowCell *) currentObject;
cell.profile_image.profileID=nil;
if(cell.profile_image.profileID.length>0)
{
return cell;
}
break;
}
}
cell.profile_image.profileID = idToImage;
NSString *text = msg.msg;
cell.lblMessage.text=text;
return cell;
}
else
{
NSString *CellIdentifier = @"Cell";
ChatCellMe *cell = nil;
cell = (ChatCellMe *)[tableChat dequeueReusableCellWithIdentifier:CellIdentifier];
// if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"ChatCellMe" owner:nil options:nil];
for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[ChatCellMe class]])
{
cell = (ChatCellMe *) currentObject;
NSLog(cell.prof_img.profileID);
cell.prof_img.profileID=nil;
if(cell.prof_img.profileID.length>0)
{
return cell;
}
break;
}
}
cell.prof_img.profileID = user.fid;
NSString *text = msg.msg;
cell.lblText.text=text;
isMessageFromMe=false;
return cell;
}
}
任何帮助都是很棒的人...
非常感谢。

我创建了一个替代视图来解决此问题,请参见https://github.com/combinatorial/DBFBProfilePictureView
关于ios - uitableview中的FBProfilePictureView每次都会自行重新创建,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/20160758/
