if you are taking form the device then it will be just greater then the screen resolution .and if it is equal or small then it will be not . hope you understand – IQworld Master Jun 05 '14 at 07:49

A panorama is just a picture with a large ratio between width and height (or vice versa).
There is no minimum or maximum (OK, there might be a maximum) size.
The ratio of a standard photo is around 4:3 (from the iPhone camera) so you could find the ratio and determine whether or not it is a panorama.
Something like...
CGFloat smallest = MIN(image.size.width, image.size.height);
CGFloat largest = MAX(image.size.width, image.size.height);
CGFloat ratio = largest/smallest;
CGFloat maximumRatioForNonePanorama = 4 / 3; // set this yourself depending on
if (ratio > maximumRatioForNonePanorama) {
// it is probably a panorama
}
However, also note that when taking a panorama you can start it a stop it without moving the camera at all so it will just be a standard photo.
This is why you have to use the ratio like this. There isn't a flag you can rely on (I think).
