类型'UIImage'的值没有成员

Question

The error I am getting says:

Value of Type 'UIImage' Has no Member 'thumbnailImage'

I have searched other questions and solutions but I don't understand how to implement them into my code. Please help me out in solving this problem.

let image = UIImage(data: newProfilePictureData)
let mediumImage: UIImage = image!.thumbnailImage(280, transparentBorder: 0, cornerRadius: 0, interpolationQuality: CGInterpolationQuality.High)
let smallRoundedImage: UIImage = image!.thumbnailImage(64, transparentBorder: 0, cornerRadius: 0, interpolationQuality: CGInterpolationQuality.Low)

Answer 1

This is how you can generate thumb image from the original Image:

func generateThumbImage() -> UIImage{

        let image: UIImage = UIImage(data: newProfilePictureData)
        let thumbSize = CGSizeMake(100, 100)
        UIGraphicsBeginImageContext(thumbSize)
        image.drawInRect(CGRectMake(0, 0, thumbSize.width, thumbSize.height))
        let thumbImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return thumbImage
    }
