Question

I have written this code to see different image states…

UIButton *btnComment = [UIButton buttonWithType:UIButtonTypeCustom];
btnComment.tag=indexPath.row;
[btnComment addTarget:self action:@selector(goToComment:)forControlEvents:UIControlEventTouchDown];

UIImage *img1 = [UIImage  imageNamed:@"commentbtndown.png"];
UIImage *img2 = [UIImage  imageNamed:@"commentbtnup.png"];
UIImage *img3 = [UIImage  imageNamed:@"commentbtnover.png"];

[btnComment setImage:img1 forState:UIControlStateNormal];
[btnComment setImage:img2 forState:UIControlStateHighlighted];
[btnComment setImage:img3 forState:UIControlStateSelected];
[btnComment setImage:img2 forState:(UIControlStateHighlighted+UIControlStateSelected)];

btnComment.frame            =CGRectMake(0, 100, 95, 25);
[cell addSubview:btnComment];

[img1 release];
[img2 release];
[img3 release];

but its not working, it is always showing me image 1.

p.s. I have added these images in the table view cell

Answer 1

The problem is that you are creating the UIImage objects with an autorelease method imageNamed, and you are releasing these objects afterwards, which cause your button to have invalid objects and because of that the images will not be displayed

Try removing this lines of code and your button will work

[img1 release];
[img2 release];
[img3 release];

And also, if you want the button to receive the touch events, you will have to add it to the contentView of your cell object, otherwise the button will be shown but you will not be able to tap it.

[cell.contentView addSubview:btnComment]
