How to properly Init a custom UITableviewCell?

Question

I am using the following 2 methods to return a custom cell:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {      NSString *key = [self keyForIndexPath:indexPath];     UITableViewCell *cell;      if ([key isEqualToString:DoneButtonCellKey]) {         cell = [self [self doneButtonCellForIndexPath:indexPath];         return cell;     } else {         //code to return default cell...     } }  

Then:

- (DoneButtonCell *)doneButtonCellForIndexPath: (NSIndexPath *)indexPath {      DoneButtonCell *cell = [self.tableView dequeueReusableCellWithIdentifier:DoneButtonCellIdentifier forIndexPath:indexPath];     return cell;  } 

What is the correct init method to use with the cell here so I can change some properties of the cell when it is initialized?

EDIT: I found the problem, as the init/awakeFromNib methods were not being called for me. I tracked down the error and it was that I had not changed the "Custom Class" from UITableViewCell to my custom class. Now awakeFromNib AND initWithCoder work as described below.

Answer 1

You can do your changes inside the DoneButtonCell's class, either in the

- (void)awakeFromNib {  .. essential to call super ..  super.awakeFromNib()  //Changes done directly here, we have an object } 

Or the initWithCoder: method:

-(id)initWithCoder:(NSCoder*)aDecoder {    self = [super initWithCoder:aDecoder];     if(self)    {      //Changes here after init'ing self    }     return self; } 

Answer 2

If you're using Swift, remember the easy way to ensure a view is initialized when it is created is to use the didSet method. For example, to make a UIImageView into a round shape you could add code like this:

@IBOutlet weak var profileImageView: UIImageView! {     didSet {         // Make the profile icon circle.         profileImageView.layer.cornerRadius = self.profileImageView.frame.size.width / 2         profileImageView.clipsToBounds = true     } }
