Question

In my custom cell subclass, when user selects a cell I want to change an image on it, which is a property by retain. No nib, everything is with code.

Problems:

-First, Even nothing is selected still the cell appears with the new image on it.

-Second, when I click nothing changes on the cell;

-(void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
UIImage *cry = [UIImage APP_CRYSTAL_SELECTED];
self.leftImage = [[[UIImageView alloc] initWithImage:cry] autorelease] ;
[self.contentView addSubview:self.leftImage];
 }

Answer 1

You do not check to see if it is selected or not in your code example.

-(void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];
    if(selected)
    {
        UIImage *cry = [UIImage APP_CRYSTAL_SELECTED];
        self.leftImage = [[[UIImageView alloc] initWithImage:cry] autorelease] ;
        [self.contentView addSubview:self.leftImage];
    }
    else
    {
        //Remove image here if it exists
    }
}
