Error:There is a duplicate ‘system.web.extensions/scripting/scriptResourceHandler’ section defined
Error like this is usually occurs in IIS after deploying a working website (local).
In my case, this error usually comes in when I use a .Net Framework higher version in IIS than the .Net Framework I use in my website application. One of the solutions that I applied was to upgrade the .Net Framework in my apps to make the same as IIS.

You will encounter this type of error when running the wcf service in local machine, one of the reasons this error occurs is when you rename the .svc file.

How to get new image size in UIImageView
Sometime we need to know the new size of the image that’s being rendered in UIImageView with auto scaled applied. Here’s the computation
-(CGRect)frameForImage:(UIImage*)image inImageViewAspectFit:(UIImageView*)imageView
{
float imageRatio = image.size.width / image.size.height;
float viewRatio = imageView.frame.size.width / imageView.frame.size.height;
if(imageRatio < viewRatio)
{
float scale = imageView.frame.size.height / image.size.height;
float width = scale * image.size.width;
float topLeftX = (imageView.frame.size.width - width) * 0.5;
return CGRectMake(topLeftX, 0, width, imageView.frame.size.height);
}
else
{
float scale = imageView.frame.size.width / image.size.width;
float height = scale * image.size.height;
float topLeftY = (imageView.frame.size.height - height) * 0.5;
return CGRectMake(0, topLeftY, imageView.frame.size.width, height);
}
}
