如何将NSData对象转换为UIImage？使用Swift

Question

我有一个NSData数组中的图像数组。如何将它们全部转换为图像数组而不用手动操作？我用这行代码（let yourImage = UIImage(data:NsdataArray) ）

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

Answer 1

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

Answer 2

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 3

for循环的解决方案：

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 
    } 
}
