How do I view images in full screen programmatically in iOS?

Answer 1

在图像显示中，将UIImageView的contentMode视为UIViewContentModeScaleAspectFit和UIViewContentModeCenter 。

Answer 2

Add an imageview for your screen what ever you want, display image on that using

imageview.image = [UIImage imageNamed:@"image.jpg"];

if you want back just remove imageview on a button click or timer what ever you wane using

[imageview removeFromsuperview];
