NIB如何在运行中loadnib文件

Loading a Nib file, Programmatically (Objective-C)

---

If you want to load a Nib file at run time by simply allocating and initializing a View object, then you should take a rather strange approach to how you create your class files. Suppose you have a subclass of UIView called MyView and what you want is to allocate and initialize an instance of MyView but have MyView load its outlets and actions from a Nib file. Well, you will need to do two things:

1) In Interface Builder, change the class name of your View object to MyView.


2) Then you will have to override MyView's initWithFrame method like so:

- (id)initWithFrame:(CGRect)paramFrame
{

    

    NSArray *arrayOfViews = [[NSBundle mainBundle] loadNibNamed:@"MyView"

                                                          owner:nil

                                                        options:nil];

    

    if ([arrayOfViews count] < 1){

        [self release];

        return nil;

    }

    

    MyView *newView = [[arrayOfViews objectAtIndex:0] retain];

    [newView setFrame:paramFrame];

    

    [self release];

    self = newView;

    

    return self;

    
}

Then you can go ahead and initialize your view like this:

MyView *myView = [[MyView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:myView];
[myView release];

And here an instance of MyView will get added to the view of a view controller. That simple. I
hope it helps some of you out there :-)
