UITableViewCell's textLabel.text is being partially substituted by ellipsis - iphone

Question

I have a UITableView with several UITableViewcells (UITableViewCellStyleSubtitle). When the user taps on one of cells, I push a detail VC that allows the user to change the text of the cell. When I pop this ViewController, the text on the cell appears abbreviated with an ellipsis:
Before:
After:
After changing the text to "Wartyrl" and popping the detail VC.
If I tap on any other cell, the ellipsis disappears and the correct text is displayed. What might be causing this?
This is the code that changes the text of the cell (via a delegate method):
#pragma mark - FRREditTaskViewControllerDelegate
-(void) editTaskViewController:(FRREditTaskViewController *)sender
didChangeNameForTask:(FRRFlatTask *)aTask{
NSIndexPath *idx = [NSIndexPath indexPathForRow:[self.pendings indexOfObject:aTask] inSection:0];
[self.tableView cellForRowAtIndexPath:idx].textLabel.text = aTask.name;
}
BTW, this code is called before popping the detail VC and while the UITableViewController is still hidden. I don't know if this is relevant.

Answer 1

When the cell is created, the UILabel is only large enough to handle the initial text (it doesn't dynamically resize). Calling [self.tableView reloadData] after changing the text (end of your didChangeNameForTask method) should make it display properly.

Answer 2

You can call [cell.textLabel sizeToFit].
In many cases it's cleaner to instead update your internal data and call reloadRowsAtIndexPaths:withRowAnimation:. That way you don't have so many pieces monkeying with the implementation details of the cell (when you change your mind on how to lay it out). It also ensures that your real data matches the cell.
Even better in most cases is to create a UITableViewCell subclass called TaskTableViewCell. You hand it a Task and it observes the Task with KVO, managing its own layout (including calling sizeToFit when needed). That way you don't need delegate methods to tell you when it updates. When the task changes, the cell automatically updates itself. This moves all the layout issues into the cell class and out of the datasource.

Answer 3

It seems that the textLabel hesitates to resize its width. If its too adamant to change, just reload the tableView directly using [tableView reloadData].
If you don't want to reload the entire tableView, you can reload just a particular cell like that following.
NSIndexPath *idx = [NSIndexPath indexPathForRow:[self.pendings indexOfObject:aTask] inSection:0];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:idx] withRowAnimation:UITableViewRowAnimationFade];
This will show a nice fade animation when changing the textLabel's text of the cell.

-(void) editTaskViewController:(FRREditTaskViewController *)sender
didChangeNameForTask:(FRRFlatTask *)aTask{
NSIndexPath *idx = [NSIndexPath indexPathForRow:[self.pendings indexOfObject:aTask] inSection:0];
UITableViewCell *thiscell=[self.tableView cellForRowAtIndexPath:idx];
thiscell.textLabel.text =[nsstring stringwithFormat:#"%#",aTask.name];
[self.tableView reloadRowsAtIndexPaths: [NSArray arrayWithObject:idx] withRowAnimation:NO];//if u dont want to use reload data then use like this or use
//- (void)reloadSections:(NSIndexSet *)sections withRowAnimation:(UITableViewRowAnimation)animation
}
