    UIImage *clear_hover_img = [UIImage imageNamed:@"0_hover.png"];
    clear=[[UIButton alloc]init];
    [clear setTitle:@"Clear" forState:UIControlStateNormal];
    //clear.tag =12;
    clear.titleLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:32];

    if(clear.selected=TRUE){
        [clear setBackgroundImage:clear_img forState:UIControlStateSelected];
        [clear setBackgroundImage:clear_hover_img forState:UIControlStateNormal];
    }

    [clear setFrame:CGRectMake(1, 360, 159, 50)];
    [clear addTarget:self action:@selector(clearInput)
    forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:clear];
}

-(void)clearInput {

    textfield.text = @"";
    UIImage *lookup_img = [UIImage imageNamed:@"0_.png"];
    [lookup setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];

For state TouchUpInside, Button Image Opacity decrease to 0.5. try this- 

if(clear.selected == TRUE){
    [clear setBackgroundImage:clear_img forState:UIControlStateSelected];
    [clear setBackgroundImage:clear_hover_img forState:UIControlStateNormal];
    [clear setBackgroundImage:clear_hover_img UIControlStateHighlighted];
}

I think you wants to set Clear button Image as Lookup button. you had done with that but when you press on clear button the image get some darken.

If my understanding is right then you had done:

[clear setBackgroundImage:clear_img forState:UIControlStateSelected];
[clear setBackgroundImage:clear_hover_img forState:UIControlStateNormal];

add this line too:

[clear setBackgroundImage:clear_img forState:UIControlStateHighlighted];

Hope this helped
