Objective C: My custom -init method not getting called

I have a class that I'm deriving from UIView, and I wanted to create a -init class for it like so:

- (id) init
{
    if (self = [super init]) {
        // my initializations here
    }
    return self;
}

Unfortunately I know for a fact that -init is not getting called. Here is how I define it in my .h:

-(id)init;

Anybody know why it's not getting called?

ADDENDUM:

I found that when I put my initialization in initWithCoder, it is run just fine. I added initWithFrame but that wasn't called.

This is for an object that I specified in IB.

There are two designated initializers for UIViewController and UIView they are initWithCoder called from nib, and initWithFrame called from code. Init is not the designated initializer for those objects.

If you want to cover both bases you can do something like this:

-(void)initializationCodeMethod{
    <#Initialization Code Here#>
}
-(id)initWithFrame:(CGRect)frame{
    if ((self = [super initWithFrame:frame])){
        [self initializationCodeMethod];
    }
    return self;
}
-(id)initWithCoder:(NSCoder *)aDecoder{
    if ((self = [super initWithCoder:aDecoder])){
        [self initializationCodeMethod];
    }
    return self;
}
