Question

I’m struggling with some basics in my storyboard-based iOS Application.

I like to load some UIView’s which are builded up in NIB-Files (xib). If I load the View, the initWithCoder-method will be called.

Now I like to load “green” Views; I read, that I’m able to put some other initializations in the initWithCoder – but only “new” objects and nothing, that regarding the View itself, like self.backgroundColor in cause of memory (maybe the object isn’t complete initialized at that point).

Where is the best place to add some stuff, like setBackgroundColor, setCornerRadius in the view-Class itself?

Answer 1

I’m doing it like this:

NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"MyCustomView" owner:nil options:nil];
self = [nibViews objectAtIndex: 0]; //here it would be best practice to loop through nibViews and get the first view that is member of your class. 

Also , the view , in the nib file is set as a MyCustomView instead of UIView.
After these 2 lines you can set any values that you want. Be aware though , if you set the frame for super for example , it will be overwritten by the values in the xib file. So better set everything AFTER loading the nib , not before.

As far as I know , there are no callbacks for UIView loading as viewDidLoad is for UIViewController.

Hope this helps.

Cheers!

EDIT:

You can do something like this:

- (id)initWithInfo:(MyInfoClass *) selectedInfo Body:(NSString *) _body
{
    if ((self = [super init]))
    {
         NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"MyCustomClass" owner:nil options:nil];
         self = [nibViews objectAtIndex: 0];

         [self setInfo:selectedInfo];
         [self setBody:_body];
    }
}

And then just use that initWithInfo: Body: method.
