Apple have changed the UITableViewController template in iOS 6 a bit. Specifically, when you create a new UITableViewController class, it’s created using something like this (in the cellForRowAtIndexPath method):
|
1 2 3 4 5 6 7 8 9 |
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; // Configure the cell... return cell; } |
When run in iOS 5 the app crashes. The culprit seems to be the addition of forIndexPath:indexPath in this declaration which is only available in iOS 6. To make it work in either iOS version, simply take it out, like so:
|
1 |
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier; |
The full code from an iOS 5 template is:
|
1 2 3 4 5 6 7 8 9 |
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier; // Configure the cell... return cell; } |
It appears that this problem has been fixed in Xcode 4.6: when you create a new UITableViewController subclass, it’s back to what it was in iOS 5.
Thank you, Apple!
