Calling awakeFromNib from xib file in the main ViewController - objective-c

Question

I have a custom cell in a UITableView using an xib file. I programatically created a UILabel with a height of 200 and a width of 50. When I do an NSLog in the customCell.m of the label's width and height, it gives me w: 50 and h: 200. But when I do an NSLog in mainViewController.m it gives me 0 for the height and width.
Not sure why it does that. I need to get the real height of the label in the mainViewController.m
Here's my code:
customCell.m
- (void)awakeFromNib
{
self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
[self.label setText:#"This is a label"];
[self.myView addSubview:self.label];
NSLog(#"%f", self.label.frame.size.height); // Results: 200.0000
}
mainViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
customCell *cellVC = [[cutsomCell alloc] init];
NSLog(#"%f, %f", cellVC.label.frame.size.height); // Results: 0.0000
}
Isn't awakeFromNib supposed to get called the mainViewController.m at viewDidLoad if I use an xib file? If not, how do I call it in viewDidLoad?

Answer 1

awakeFromNib is an initializer called when you load from nib..ie you add a view and change its class to your custom class in storyboard/nib and this porcess will call awakeFromNib method..not programatically
When done programatically use init method for the purpose or a custom initializer
-(id)init
{
//class super init calls
//then method calls
self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
[self.label setText:#"This is a label"];
[self.myView addSubview:self.label];
//return self
}
Example
- (id) init {
// Call superclass's initializer
self = [super init];
if(self) {
self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 50, 200)];
[self.label setText:#"This is a label"];
[self.myView addSubview:self.label];
}
return self;
}
