Subclass of UIView. How to add through Interface Builder?

Question

I have a subclass of UITextField and want to be able to add it to the view in IB. What I did is added UITextField and changed its class to my subclass in Identity tab of Inspector. But I can only see UITextField on the view.

Code:

@interface ExtendedTextField : UITextField {
}

//implementation


@implementation ExtendedTextField

- (void)baseInit
{
    UIImage * curImage = [UIImage imageNamed:@"tfbg.png"];
    [self baseInitWithImage : curImage];
}

- (void)baseInitWithImage : (UIImage *) aImage
{
    aImage = [aImage stretchableImageWithLeftCapWidth:29 topCapHeight:29];
    self.background = aImage;
    self.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;

    UIView * curLeftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, self.frame.size.height)];

    self.leftView = curLeftView;
    self.rightView = curLeftView;
    [curLeftView release];
    self.leftViewMode = UITextFieldViewModeAlways;
    self.rightViewMode = UITextFieldViewModeAlways;
    [self setTextColor:[UIColor greenColor]];
}

- (void)awakeFromNib
{
    [super awakeFromNib];
    [self baseInit];
}

/*
- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        [self baseInit];
    }
    return self;
}
*/

- (id)initWithFrame:(CGRect)frame {
    self = [super initWithFrame:frame];
    if (self)
    {
        [self baseInit];
    }
    return self;
}

- (id)initWithFrame:(CGRect)frame withImage:(UIImage*)aImage
{
    self = [super initWithFrame:frame];
    if (self) {
        [self baseInitWithImage : aImage];
    }
    return self;
}

- (void)dealloc {
    [super dealloc];
}


@end

EDIT: I noticed several things:

-- if I put [super initWithFrame:...] instead of [super initWithCoder:...] inside

(id)initWithCoder:(NSCoder *)aDecoder

it works well.

-- Now I am using awakefromnib instead of initwithcoder and the only thing that get changed in textfield is textColor. Could someone explain why so?

Solution I needed to set border style to none. BS overlayed bg image.

While showing your .xib in Xcode, reveal the right pane, select your view and in the third tab, change Classto whatever you want it to be.
