How to combine two UIImages of difference size without altering their original aspect ratios?

Question

My current method of combining UIImages come from this answer on SO, as well as this popular question on resizing UIImage with aspect ratio. My current issue is the following:<

Answer 1

• Support Portrait and Landscape both type of image
• Drawing and other subviews can be merged in my case I'm adding label to draw

  {

    CGSize fullSize = getImageForEdit.size;
    CGSize sizeInView = AVMakeRectWithAspectRatioInsideRect(imgViewFake.image.size, imgViewFake.bounds).size;
    CGFloat orgScale = orgScale = fullSize.width/sizeInView.width;
    CGSize newSize = CGSizeMake(orgScale * img.image.size.width, orgScale * img.image.size.height);
    if(newSize.width <= fullSize.width && newSize.height <= fullSize.height){
        newSize = fullSize;
    }
    CGRect offsetRect;
    if (getImageForEdit.size.height > getImageForEdit.size.width){
        CGFloat scale = newSize.height/fullSize.height;
        CGFloat offset = (newSize.width - fullSize.width*scale)/2;
        offsetRect = CGRectMake(offset, 0, newSize.width-offset*2, newSize.height);
    }
    else{
        CGFloat scale = newSize.width/fullSize.width;
        CGFloat offset = (newSize.height - fullSize.height*scale)/2;
        offsetRect = CGRectMake(0, offset, newSize.width, newSize.height-offset*2);
    }
    UIGraphicsBeginImageContextWithOptions(newSize, NO, getImageForEdit.scale);
    [getImageForEdit drawAtPoint:offsetRect.origin];
    //        [img.image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    CGFloat oldScale = img.contentScaleFactor;
    img.contentScaleFactor = getImageForEdit.scale;
    [img drawViewHierarchyInRect:CGRectMake(0, 0, newSize.width, newSize.height) afterScreenUpdates:YES];
    img.contentScaleFactor = oldScale;
    UIImage *combImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    imageData = UIImageJPEGRepresentation(combImage, 1);
}
