我在本地图像路径上遇到了同样的问题，通过设置正确的路径解决了
实用功能
var TimestampJPGImageName :String {
var stringTimeStamp = "\(NSDate().timeIntervalSince1970 * 1000)"
stringTimeStamp = stringTimeStamp.stringByReplacingOccurrencesOfString(".", withString: "_")
stringTimeStamp = stringTimeStamp.stringByAppendingString(".jpg")
stringTimeStamp = stringTimeStamp.stringByAddingPercentEncodingWithAllowedCharacters( NSCharacterSet.URLQueryAllowedCharacterSet())!
return stringTimeStamp
}
func fileUrlForPathComponent(pathComponent: String) -> NSURL?{
let pathDocumentDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
let filePath = "\(pathDocumentDirectory)/\(pathComponent)"
let fileUrl = NSURL(fileURLWithPath: filePath)
return fileUrl
}
func fileSaveToDirectory(image: UIImage, name: String?) -> NSURL? {
//let fileManager = NSFileManager.defaultManager()
//fileManager.createFileAtPath(fileUrlToWrite!.path, contents: imageData, attributes: nil)
var fileUrlToWrite : NSURL? = nil
if let fileName : String = name {
fileUrlToWrite = fileUrlForPathComponent(fileName)//.stringByAppendingString(".png")
}else{
fileUrlToWrite = fileUrlForPathComponent(TimestampJPGImageName)//.stringByAppendingString(".png")
}
assert(fileUrlToWrite != nil, "please check filePath")
if (fileUrlToWrite != nil){
let imageData: NSData = UIImageJPEGRepresentation(image, 0.6)!
imageData.writeToFile(fileUrlToWrite!.path!, atomically: false)
return fileUrlToWrite!
}
else{
return nil
}
}
func fileRemoveAtURL(URL : NSURL) ->(success : Bool?, message : String?){
if let path : String = URL.path{
let fileManager = NSFileManager.defaultManager()
do {
try fileManager.removeItemAtPath(path)
}
catch let error as NSError {
return (false, error.localizedDescription)
}
return (true, "file removed!")
}else{
