uitableview reloadRowsAtIndexPaths not working - iphone

Question

I have a tableviewcell in the RegisterViewController, when i click on it, it push to the SelectCityViewController where i can pick a city from a uipickerview. and I have defined a delegate in the SelectCityViewController. But when i implement the delegate method, i got the city back from the pickerview and the selected indexpath from didSelectRowAtIndexPath in RegisterViewController. When i check the log, i get the city, and the selected indexpath. but when i call reloadRowsAtIndexPaths, the cell still got the old titlelabel text. the code:
SelectCityViewController.h
#protocol SelectCityDelegate <NSObject>
- (void)didGetCity:(City *)city;
#end
SelectCityViewController.m
- (void)finished:(UIBarButtonItem *)buttonItem
{
if ([self.delegate respondsToSelector:#selector(didGetCity:)]) {
[self.delegate didGetCity:self.city];
}
NSLog(#"%#", self.city.city);
[self.navigationController popViewControllerAnimated:YES];
}
RegisterViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == 2) {
self.selectedIndexPath = indexPath;
UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:#"MainStoryboard_iPhone" bundle:nil];
SelectCityViewController *signUp = [storyBoard instantiateViewControllerWithIdentifier:#"SignVC"];
signUp.delegate = self;
[self.navigationController pushViewController:signUp animated:YES];
}
}
- (void)didGetCity:(City *)city
{
NSLog(#"%#", city.city);
NSLog(#"%#", selectedIndexPath);
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:selectedIndexPath];
cell.textLabel.text = city.city;
[self.tableView reloadRowsAtIndexPaths:#[selectedIndexPath] withRowAnimation:UITableViewRowAnimationFade];
}

Answer 1

I think the problem is in the below code you don't have to set the value here, because when you will reload, it will override the value with what is in the function where you are creating your cells.
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:selectedIndexPath];
cell.textLabel.text = city.city;
Just reload the cell, and put above code in your
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
//Cell intialization and other things
cell.textLabel.text = city.city;
}

didGetCity needs to update the model that backs the table, not the table cell itself. How do you answer numberOfRowsInSection:? With the count of some array?
That array at index selectedIndexPath.row needs to change. cellForRowAtIndexPath: should initialize the cell with that same data. Then your didGetCity method updates the array and reloads. It should not refer to cells.
