ios - Programmatically set image and text on UIButton

I need to create button programatically with an image for normal and highlighted state as well text. I cannot build it using Interface Builder, because I need to create buttons over a UIScrollView. Here is the code I have so far:

- (void)loadView {
    CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
    scrollView=[[UIScrollView alloc] initWithFrame:fullScreenRect];
    scrollView.contentSize=CGSizeMake(320,960);

    UIImageView *tempImageView2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.jpeg"]];

    UIImage * buttonImage = [UIImage imageNamed:@"contentlist_active.png"];

    self.view=scrollView;
    [scrollView addSubview:tempImageView2];

    btn = [UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame = CGRectMake(22, 100, 277, 32);

    [btn setImage:buttonImage forState:UIControlStateNormal]; 

    [btn setTitle:@"hello world" forState:UIControlStateNormal];
    [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    [scrollView addSubview:btn];

}

But the text on the button is not showing. If I comment out the setImage for button, then text shows perfectly, otherwise not. Can I have both text and an image at the same time?

UIButtons setImage sets the image above the title so you will not be able to see the text below it. So try to set image to your button with setBackgroundImage.

Objective-C:

[btn setBackgroundImage:buttonImage forState:UIControlStateNormal]; 

Swift:

myButton.setBackgroundImage(buttonImage, forState: .normal)
