Question

Im trying to add a uibarbutton- Camera style to a uitableviewcell programmatically like so
but I dont see anything in the uitableviewcell

UIButton *newBtn=[UIButton buttonWithType:UIBarButtonSystemItemCamera];
        [newBtn setFrame:CGRectMake(250,10,50,30)];
        [newBtn addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
        [newBtn setEnabled:YES];
        [cell addSubview:newBtn];

but when I use this code, I see a rounded rect button in the uitableviewcell

  UIButton *newBtn=[UIButton buttonWithType:UIButtonTypeRoundedRect];
        [newBtn setFrame:CGRectMake(250,10,50,30)];
        [newBtn addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
        [newBtn setEnabled:YES];
        [cell addSubview:newBtn];

Is there any way I can add a uibarbuttonstyle button or all I can do is add a uibutton rounded rect style to the uitableviewcell?

UIBarButtonItem is not the same as UIButton. It doesn’t even inherit from UIView, so you can’t add it as a subview to other views. What happens when you call

[UIButton buttonWithType:UIBarButtonSystemItemCamera]

is that the UIBarButtonSystemItemCamera constant is of an invalid value for buttonWithType:, so UIButton can’t decide which type of button to return – probably it just returns an empty, not configured one or nil.

So there’s no easy solution to your problem. What you can do is, for example, take a screenshot of the Camera bar button item, then extract its image using some kind of image editor application, then set that image as the image of a custom UIButton like this:

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setImage:[UIImage imageNamed:@"Camera.png"] forState:UIControlStateNormal];
[cell.contentView addSubview:btn];
