Question

I’ve a UIButton on cell of UITableView in my VC like this

arrowBtnUp = [UIButton buttonWithType:UIButtonTypeCustom];
arrowBtnUp.frame = CGRectMake(50,(65-19)/2,31, 31);
[arrowBtnUp setBackgroundImage:[UIImage imageNamed:@"arrow_up.png"] forState:UIControlStateNormal];
[arrowBtnUp addTarget:self action:@selector(slideAction) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:arrowBtnUp];

and this my slideAction

-(void) slideAction
{
    [arrowBtnUp setBackgroundImage:[UIImage imageNamed:@"arrow_down.png"] forState:UIControlStateNormal];
    // also tried  with UIControlStateSelected/Highlighted
}

But it didn’t work.I found this link but didn’t help.
Any suggestion or sample would be appreciated.

Answer 1

Your code should work.Anyways change your code like this and try

-(void) slideAction:(id)sender
{
   [sender setBackgroundImage:[UIImage imageNamed:@"arrow_down.png"] forState:UIControlStateNormal];
}

and

[arrowBtnUp addTarget:self action:@selector(slideAction:) forControlEvents:UIControlEventTouchUpInside];

and ensure that you have arrow_down.png in your app bundle
