Custom UIButton which wil show and hides an image

[TUX2K]

I'm stuck on the following code.
Some how my UIButton Extended class cant show or hide an UIImageView

My methods are being called and the imageview is not nil.

Here is the code:

@interface UILinkedImageButton : UIButton {
	IBOutlet UIImageView *linkImageView;
}

@property (nonatomic, retain) IBOutlet UIImageView *linkImageView;

@end

#import "UILinkedImageButton.h"

@interface UILinkedImageButton ()
- (void)showImage;
- (void)hideImage;
@end


@implementation UILinkedImageButton


@synthesize linkImageView;

- (void) dealloc{
	
	[linkImageView release], linkImageView = nil;
	[super dealloc];
}

- (id) initWithCoder:(NSCoder *)aDecoder
{
	self = [super initWithCoder:aDecoder];
	
	if(self){
		[self addTarget:self action:@selector(showImage) forControlEvents:UIControlEventTouchDown];
		[self addTarget:self action:@selector(hideImage) forControlEvents:UIControlEventTouchUpInside];
		[self addTarget:self action:@selector(hideImage) forControlEvents:UIControlEventTouchUpOutside];
	}
	
	return self;
}

- (void)showImage
{
	if(self.imageView){
		NSLog(@"UILinkImageButton - showImage - currentStatus: %@", self.imageView);
		self.imageView.hidden = NO;
		[self.superview layoutIfNeeded];
	}	
}

- (void)hideImage
{
	if(self.imageView){
		NSLog(@"UILinkImageButton - hideImage");
		self.imageView.hidden = YES;
	}
}

@end

Instead of .hidden, try use:

imageView.alpha = 0.0;

You can also fade with this in an animation. If you want to show the image, increase the alpha to 1.0.

Tried that, still the images won't show. if I move all the methods to the view controller it all works.

But there are many buttons so a class like this would really help.
Anyone any suggestions?

}

{
	if(self.imageView){
		NSLog(@"UILinkImageButton - hideImage");
		self.imageView.hidden = YES;
	}
}

@end

Instead of self.imageView.hidden = YES; you can try this code imageView.hidden = TRUE;
when you want to show it then you can write imageView.hidden = FALSE;

I think you get it

That still won't make it work !
