Question

I have created a UIImageview programmatically, and I am showing an image from a string which contains url of a picture

But I wish to show a part(a rectangle at center) of the original image. How do I achieve this?

    NSString * urlString = @"http://4.bp.blogspot.com/-  rEqVgkdnuxE/TWd6Fm6EWtI/AAAAAAAABSc/cWCehI51v_Y/s1600/red_rose_flower3.jpg"

   NSURL *url = [NSURL URLWithString:urlstring];
   NSData *data = [NSData dataWithContentsOfURL:url];
   UIImage *img = [[UIImage alloc] initWithData:data];

Answer 1

Try this on for size 🙂

UIImageView *imageView = [UIImageView alloc] initWithImage:image];
[imageView setFrame:SIZEOFRECTANGLE];
[imageView setContentModeCenter];
