Question

我在NSData数组中有一个图像数组。如何将它们全部转换为图像数组而不用手工制作呢？我使用这行代码（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循环解决方案：

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
   }
}
