這兩行莫名的錯(cuò)誤，google了半天，很多問(wèn)題都會(huì)導(dǎo)致這個(gè)錯(cuò)誤，例如Localization等，
但是我一行行的debug我的代碼的時(shí)候.

                for image in self.sourceImages {
                    let imageData = UIImagePNGRepresentation(image)!
                    let fileName = token.stringByAppendingString("+\(now)\(i)")
                    let fileURL = userFolder.stringByAppendingString("/".stringByAppendingString(fileName))
                    if !(imageData.writeToFile(fileURL, atomically: true)) {
                        self.showAlertController("Alert", message: "Failed to save images.")
                        return
                    }
                    imagePathArray.append(fileName)
                    i += 1
                }

問(wèn)題好像出現(xiàn)在

let imageData = UIImagePNGRepresentation(image)!

這行， 因?yàn)槲易⑨尩暨@行就沒(méi)有問(wèn)題了。但是網(wǎng)上也搜不到解決方案。不知道有沒(méi)有人遇到過(guò)這個(gè)問(wèn)題的。
