如何将NSData对象转换为UIImage？ 使用Swift

Question

I have an array of images in an NSData array. How do i convert all of them to an image array without doing it manualy? do i use this line of code( let yourImage = UIImage(data:NsdataArray) )

var NsdataArray:[AnyObject] = [image1, image2, image3]
//convert everything to this array
var imageArray:[UIImage] = [UIImage]()

Answer 1

var imageArray =  NsdataArray.map({UIImage(data: $0)})

OR

var imageArray = [UIImage]()

    for data in NsdataArray {
        if let img = UIImage(data: data){
           imageArray.append(img)
        }
    }

Answer 2

试试这个var imageArray = NsdataArray.map({UIImage(data: $0)}) 。

Answer 3

for loop solution:

var NsdataArray:[AnyObject] = [image1, image2, image3]
//convert everything to this array
var imageArray:[UIImage] = [UIImage]()

for aData in NsdataArray {
   var image = UIImage(data: aData as? NSData) 
   if let _image = image {
       imageArray.append(_image) 
   } else {
       //error when convert to UIImage
   }
}
