UIImageView not showing in iOS

I am loading image with text in my ViewController. The text loads and it's fine but the image doesnt.

Here is how I load them in my ViewController:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.backgroundImageView.image = [UIImage imageNamed:@"tut_1.jpeg"];
    self.titleLabel.text = self.titleText;
      NSLog(@"%@",  self.backgroundImageView);
      NSLog(@"%@",  self.backgroundImageView.image);
      NSLog(@"%@",  self.titleLabel.text);

}

The output of the NSLogs is "some text" for the self.titleLabel.text and NULL for the self.backgroundImageView.image.

Strange because NSLog of self.backgroundImageView is not NIL but:

UIImageView: 0x14deaffb0; frame = (0 0; 240 128); autoresize = RM+BM; userInteractionEnabled = NO; layer =

The image tut_1.jpeg exits and the name is written correctly.

I also have the correct outlet referencing in my header file by dragging from the interface builder:

Try only writing tut_1and not tut_1.jpeg – Randy
Try to create UIImage *testImage = [UIImage imageNamed:@"tut_1.jpeg"]; to check if the image is in asset ? – Martin Le
Do you use auto layout in your project? – Ulaş Sancak
Yes, I use auto layout. – radioaktiv
So the only explanation here is the file can't be found or it is not an image file that UIImage can handle. – Ulaş Sancak

Possibility 1:

No, you don't. If you log, you will see that self.backgroundImageView is nil, because the outlet from the nib is not hooked up to it.

Possibility 2:

The image tut_1.jpeg exits and the name is written correctly

No, it doesn't. If you log [UIImage imageNamed:@"tut_1.jpeg"], you will see that it is nil.

I found the solution. As @Ulas Sancak said the file I was referencing [UIImage imageNamed:@"tut_1.jpeg"] couldn't be handled by UIImage. So I simply converted the image from jpeg to PNG format and it worked !
