1use contentMode property of imageView. you can use aspectFit or Fill or centre etc – santhu Feb 24 '14 at 17:56

you do know the ratio of image for iphone 5 is 640 x 1136 and not a square? Do the math. – Sam B Feb 24 '14 at 18:25

It's not possible. A single 200x200 image cannot fill a space larger than 200x200 without stretching/scaling.
You do have various options for displaying it in an UIImageView though See Apple's Documentation on UIViewContentMode for the contentMode options.
UIImage *img = [UIImage imageNamed:@"glyph"];
self.imageView.image = img;
self.imageView.contentMode = UIViewContentModeScaleAspectFit;

i dont want it in aspect fit..because if image is as shown as it fits in our screen but i want it ti display in full height in iphone – prajapatijayesh Feb 25 '14 at 17:34

I have seen/done this two ways. The first way is to have two images and switch between them when the device rotates between portrait and landscape. The other way is to have an image that's bigger than the screen, realizing some of the image will be cropped out in each orientation (I've only had this technique useful a couple times). – DBD Feb 25 '14 at 20:20

yes you'r right...this thing help us many times but in my this app i particular need to show image in full screen whatever image size..I also think thats not possible because if image is of 200x200 and you resize it in 320x524 it will be stretched. Do you know any library like imagepicker editing mode allow through which user can crop image in whatever size they want by adjusting cropview??? – prajapatijayesh Feb 27 '14 at 08:23

Sorry, that I don't know. I have not had the opportunity to write any code which involved users manipulating images. – DBD Feb 27 '14 at 18:16

You need to resize the image with size of full screen size and then display on full screen. For reference, please check the following answer:
