UIImage view does not display the image

I'm having a few issues with displaying a UIImage in an app that I'm developing. The steps I took to do this are as follows:

1 - Add a UIImageView to my main view controller in the storyboard. I did this using the interface builder.

2 - I then created an IBOutlet for the UIImageView in the viewcontroller.h. I ensured proper referencing of the image view from the outlet.

3 - I set the image for the UIImageView like so:

_fireIcon = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"flame_icon.png"]];

This was done within the viewDidLoad method in the viewcontroller.m file.

Troubleshooting:

  • I checked whether the _fireIcon variable is being set. It is.
  • I checked whether the viewDidLoad method is being called. It is.
  • In addition, the image is displayed when I statically set it via the storyboard itself. But when I do it via code, it does not display.

Let me know if you need any more additional information, or code snippets.

Solution

  • you need not to initialize an imageview as you are using Interface builder for image view

    _fireIcon.image = [UIImage imageNamed:@"flame_icon.png"]; // or  [_fireIcon setImage:[UIImage imageNamed:@"flame_icon.png"]];

    This sets the image. When we drop the UI elements using Interface builder , we need not initialize them, as they are taken care by apple.
