Question

I am getting images asynchronously and show them on small frame (135,126) and on big frame (280,325) and image can be any size but frames are fixed and must have to fill frames, now my question is how resize image to fill these sizes of frame but quality should not reduce and also orientation of images like UIViewContentModeScaleAspectFill property do????

Answer 1

        UIImage *image = [actualImage you want to resize];
        UIImage *tempImage = nil;
        CGSize targetSize = CGSizeMake(196,110);
        UIGraphicsBeginImageContext(targetSize);

        CGRect thumbnailRect = CGRectMake(0, 0, 0, 0);
        thumbnailRect.origin = CGPointMake(0.0,0.0);
        thumbnailRect.size.width  = targetSize.width;
        thumbnailRect.size.height = targetSize.height;

        [image drawInRect:thumbnailRect];

        tempImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        You can use this tempImage , it will be resized Image

Hope, it helps !
