custom View for universal application - iphone

Question

I believe, that this question is duplicated, but i can't find it =(.
How to create own UIView class, which is loaded from (iPhone/iPad)*.xib
I was trying next things:
#interface CurtainView : UIView
...
- (id)init {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self = [[[NSBundle mainBundle] loadNibNamed:#"CurtainView_iphone" owner:self options:nil] objectAtIndex:0];
[self setFrame:CGRectMake(0, 0, 320, 460)];
}
else {
self = [[[NSBundle mainBundle] loadNibNamed:#"CurtainView_ipad" owner:self options:nil] objectAtIndex:0];
[self setFrame:CGRectMake(0, 0, 768, 1004)];
}
return self;
}
- (void)drawRect:(CGRect)rect
{
NSLog(#"there should be some animation on view appirance");
}
and ...
CurtainView* curtain = [[CurtainView alloc] init];
NSLog(#"before");
[self.view addSubview:curtain];
[curtain drawRect:CGRectMake(0, 0, 320, 460)];
But in this case, I haven't the result which I'm expecting, and drawRect isn't calling. I hope there is easy way to create custom Views for universal Apps.

Answer 1

put this code in .h file
#import
#interface CurtainView : UIView
#end
put this code in .m file
#import "CurtainView.h"
#implementation CurtainView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect{
// Drawing code
NSLog(#"there should be some animation on view appirance");
}
now call this UIView form your viewcontroller class. this will call drawRect
CurtainView* curtain = [[CurtainView alloc] init];
NSLog(#"before");
[curtain drawRect:self.view.frame];
[self.view addSubview:curtain];
you can call your viewcontroller class
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil];
} else {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil];
}

Answer 2

ok. sorry, I got my misstake:
it's need to use :
[self addSubview:[[[NSBundle mainBundle] loadNibNamed:#"Curtain_iPhone" owner:self options:nil] objectAtIndex:0]];
instead my:
self = [[[NSBundle mainBundle] loadNibNamed:#"CurtainView_iphone" owner:self options:nil] objectAtIndex:0];
Hope it will helpful for some one.
moreover, I don't know why, but property "opaque" for the View should be set in "init" method, not only in IB.
