我有两个班级
代表一个帖子,并且可以选择对帖子发表评论。要发表评论,用户必须访问评论页面评论类。当用户对其发表评论时,我希望将总评论数量传递到时间轴页面,在该页面中,它会在单元格的评论标签中显示评论数字 所以在我的评论课中,我在评论成功发布时这样做了:
TimelineViewController *t = (TimelineViewController *)self.navigationController.viewControllers[0];
t.updateWill = YES;
t.updateId = self.index;
t.updateValue =(int)self.response.responseData.count+1;
在 cellForRowAtIndexPath 下的我的时间轴课程中,我尝试了这个:
if(self.updateWill == YES)
{
NSLog(@"YES YES");
data.commentCount= self.updateValue;
}
else
{
data.commentCount = (int)data.comments.count;
}
cell.commentLabel.text = [NSString stringWithFormat:@"%d comments",data.commentCount];
NSLog(@"是是")表示逻辑有效。如果我打印self.updatevalue,它也会显示正确的结果,但标签保持不变。我做错了什么?

在viewDidAppear上的时间轴课程
(void)viewDidAppear:(BOOL)animated
{
[[ApiAccess getSharedInstance] setDelegate:self];
[[[SocektAccess getSharedInstance]getSocket]setDelegate:self];
[[[SocektAccess getSharedInstance]getSocket] reconnect];
_chatSocket =[[SocektAccess getSharedInstance]getSocket];
if(self.updateWill)
{
NSLog(@"viewDidAppear");
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.updateId inSection:0];
NSLog(@"Update Value: %d",self.updateValue);
NSLog(@"Update ID: %d",self.updateId);
TimelineTableViewCell *cell = (TimelineTableViewCell *)[self.tableData cellForRowAtIndexPath:indexPath];
WallPost *data = self.myObject[indexPath.row];
data.commentCount = self.updateValue;
[self.myObject replaceObjectAtIndex:indexPath.row withObject:data];
WallPost *data2 = self.myObject[indexPath.row];
NSLog(@": %d",data2.commentCount);
[self.tableData reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationNone];
[self.tableData reloadData];
}
self.updateWill = NO;
}
时间轴类中的cellForRowAtIndexPath:
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
TimelineTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
self.counter = 0;
WallPost *data = self.myObject[indexPath.row];
cell.image.userInteractionEnabled = YES;
cell.image.tag = indexPath.row;
if(self.updateWill == YES)
{
NSLog(@"YES YES");
NSLog(@"Updated value : %d", (int)self.updateValue);
data.commentCount= (int)self.updateValue;
}
else
{
data.commentCount = (int)data.comments.count;
}
