problem with UIButton background color

[roko]

hi guys!

Here is screenshot where is my buttons(UIButton with custom image). Behind the buttons you can see white background colour:


How to take that white background away?

I was trying to sort it out working with next UIButton' methods:setTitleColor, setTitleShadowColor and setBackgroundColor, but it doesn't work.

Has anyone any idea how to remove that white background?

thanks but it doesn't help. Here is what i can see:


maybe it would be helpful to you and other to show how i create my UIButton. So here is code:

//jumpButton
UIButton *jumpButton;
		self.jumpButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
		jumpButton.frame = CGRectMake(0, 0, 55, 55);
		affTransf.tx = 10;
		affTransf.ty = 380;
		[jumpButton setTransform:affTransf];
		[jumpButton addTarget:self action:@selector(jumpButtonActionDown) forControlEvents:UIControlEventTouchDown |
		UIControlEventTouchDragEnter];
		[jumpButton addTarget:self action:@selector(jumpButtonActionUp) forControlEvents:UIControlEventTouchUpInside |
		UIControlEventTouchDragExit];
		jumpButton.backgroundColor = [UIColor blackColor];
		
		UIImage *jumpButtonImg = [UIImage imageNamed:@"jump_test.png"];
		[jumpButton setImage:jumpButtonImg forState:UIControlStateNormal];
		
		UIImage *jumpButtonImgH = [UIImage imageNamed:@"jump_n_a_test.png"];
		[jumpButton setImage:jumpButtonImgH forState:UIControlStateHighlighted];
		
		[[[[CCDirector sharedDirector] openGLView] window] addSubview:jumpButton];

		self.jumpButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

try changing that to :

 self.jumpButton = [UIButton buttonWithType:UIButtonTypeCustom];

thank you very much!

self.jumpButton = [UIButton buttonWithType:UIButtonTypeCustom]

and

biteButton.backgroundColor = [UIColor clearColor];

really helped


but i have heard that using UIButton in the Cocos2d can inhibit my program on the old device.

so i have found out this code:

biteBt = [CCMenuItemImage itemFromNormalImage:@"bite_test.png" selectedImage:@"bite_n_a_test.png" target:self selector:@selector(biteButtonActionDown)];
		biteBt.position = ccp(200,120);
		
		CCMenu * menu = [CCMenu menuWithItems:biteBt,nil];
									
		[self addChild:menu z:1000];

thank you
