Make sure that you:

  • Set your compression quality to 0.9(it MUST be between 0.0 - 1.0)
  • Set the frame of the UIImageView correctly
  • Don't make that UIImageView hidden

And if it still doesn't work then try the following:

[elementView bringSubviewToFront:imageView];

Hope it helps

The UIImageJPEGRepresentation function returns an NSData (array of bytes) which represents a content of the image if compressed in JPEG.

To display it, you just need to use the UIImage directly.

imageView.image = myImage;
