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

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 (eg, 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

  }
