How to convert a NSData object to a UIImage? Using Swift
提问by nachshon f
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))
我在 NSData 数组中有一组图像。如何在不手动执行的情况下将它们全部转换为图像数组？我是否使用这行代码（let yourImage = UIImage(data:NsdataArray)）
var NsdataArray:[AnyObject] = [image1, image2, image3]
//convert everything to this array
var imageArray:[UIImage] = [UIImage]()
回答by Christos Chadjikyriacou
var imageArray = NsdataArray.map({UIImage(data: var imageArray = [UIImage]()
for data in NsdataArray {
if let img = UIImage(data: data){
imageArray.append(img)
}
}
)})
OR
或者
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
}
}

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