Is there a way to load a prototype cell, along with any IBOutlet connections as defined within a storyboard?
Update
I want to unit test the cell (a UICollectionViewCell for that mater), hence would like to load it outside of a UIViewController context.
Effectively, in the same way that you can load a custom view from a nib, specifying its file's owner and have its IBOutlet(s) set.
Edit: As far as I know, it's not possible to use prototype UITableViewCells from a Storyboard anywhere other than the ViewController you created it in.
I haven't tried this with unit tests yet but you can easily put your custom UITableViewCell
into a separate nib.
For using it in your view controllers you need to register the cell with your tableViews.
UINib *nib = [UINib nibWithNibName:@"ABCNameOfYourNibCell" bundle:nil];
[self.tableView registerNib:nib forCellReuseIdentifier:@"myCustomCell"];
Then use the cell like this in cellForRowAtIndexPath:
static NSString *CellIdentifier = @"myCustomCell";
ABCNameOfYourNibCell *cell =
[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
For your testing purposes you should be able to go with:
ABCNameOfYourNibCell *testCell =
[[ABCNameOfYourNibCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:nil];
If you need to test reuse-behaviour, you should set a reuseIdentifier here and call prepareForReuse
on the cell.
Normally you crete an UITableViewController
or a UITableView
. Than you should also create a UITableViewCell
class. After creating the UITableViewCell
class, go to the `UIStoryboard, select the cell :
Then set the UITableViewCell
class inside the Identity Inspector
:
Now add elements to the UITableViewCell
and connect them with your class
Now add the CellIdentifier
inside the Attributes Inspector
:
No got to your UITableViewController
or the UIViewController
where you have the UITableViewDelegate
methods and call your cell like this (don't forget to #import
the UITableViewCell
class at the top of your ViewController
:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"MyIdentifier";
MyCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier
forIndexPath:indexPath];
[cell.label setText:[NSString stringWithFormat:@"My Cell at Row %ld",
(long)indexPath.row]];
return cell;
}
