I have a UITabBarController with more than 5 UITabBarItems so the moreNavigationController is available.
In my UITabBarController Delegate I do the following:
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
//do some stuff
//...
UITableView *moreView = (UITableView *)self.tabBarController.moreNavigationController.topViewController.view;
moreView.delegate = self;
}
I want to implement a UITableViewDelegate so I can capture the row that was selected, set a custom view property and then push the view controller:
- (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//how can I get the text of the cell here?
}
I need to get the text of a cell when the user taps on a row. How can I accomplish this?
add an 'indexPath` property to the custom table cell. initialize it in cellForRowAtIndexPath. move the tap handler from the view controller to the cell implementation. use the delegation pattern to notify the view controller about the tap event, passing the index path.
The Swift overlay to the Foundation framework provides the IndexPath structure, which bridges to the NSIndexPath class. This means that, as an alternative to NSIndexPath , starting with Swift 3 and Xcode 8, you can use IndexPath . Note that IndexPath also conforms to Equatable protocol. Therefore, you can use == or !=
- (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//how can I get the text of the cell here?
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSString *str = cell.textLabel.text;
}
A better Solution is to maintain Array of cell and use it directly here
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
Service *service = [self.nearMeArray objectAtIndex:indexPath.row];
cell.textLabel.text = service.name;
cell.detailTextLabel.text = service.description;
if(![self.mutArray containsObject:cell])
[self.mutArray insertObject:cell atIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self.mutArray objectAtIndex:indexPath.row];
NSString *str = cell.textLabel.text;
}
