loadNibNamed vs. initWithFrame dilemma for setting frame's height and width - ios

Question

I created a UIView subclass associated with .xib file. This UIView subclass is to be used in a UIViewController. In the controller, I think there are two options how we instantiate the UIView subclass:
MyUIView *myView=[[MyUIView alloc] initWithFrame:aRect];
and
MyUIView *myView = [[[NSBundle mainBundle] loadNibNamed:#"MyUIView"
owner:self
options:nil] lastObject];
I prefer the first approach or its variants that allow me to perform custom initialization. The only problem is that I have to specify a frame's rect, which was already specified in .xib (I mean frame's height and width of MyUIView). Yes, I can hardcode it again in aRect, but this is tedious to maintain (e.g., when I change position of UIs in .xib, I have to update aRect, too).
So the second approach should come into mind as the frame rect is automatically set. The remaining problem is I cannot customize the initializer (say, I want to pass extra parameters during initialization).
What's your preference? Which one is better in your opinion?
EDIT1:
Inspired by sergio's answer, I came out with this workaround:
// In MyViewController.m
MyUIView *myView=[[MyUIView alloc] initWithFrame:CGRectMake(x, y, 0.0, 0.0)];
// In MyView.m
- (id)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {
self = [[[NSBundle mainBundle] loadNibNamed:#"UnmovableTagView"
owner:self
options:nil] lastObject];
[self setFrame:CGRectMake(frame.origin.x,
frame.origin.y,
[self frame].size.width,
[self frame].size.height)];
// frame's width and height already determined after
// loadNibNamed was called
...
}
return self;
}

Have you tried using:
MyUIView *myView=[[MyUIView alloc] initWithFrame:CGRectZero];
I don't know if it works in your case (loading the view from a nib), but I use it successfully when I create my custom view programmatically.
You can give it a try.
EDIT:
you could define your own init method for your view:
-(id)initWithPosition:(CGPoint)pos;
and then call:
-(id)initWithPosition:(CGPoint)pos {
if (self = [super initWithFrame:{pos,{0,0}}]) {
self = [[[NSBundle mainBundle] loadNibNamed:#"UnmovableTagView"
owner:self
options:nil] lastObject];
[self setFrame:CGRectMake(frame.origin.x,
frame.origin.y,
[self frame].size.width,
[self frame].size.height)];
// frame's width and height already determined
// after loadNibNamed was called
}
