我有相同的本地圖片路徑&問題，它通過設置正確的路徑
效用函數
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{
return (false, "invalid path!")
}
}
解決
也求
func requestCreateEvent(){
if (canMakeAPIRequest() == false){
return
}
let imageJPEGname = TimestampJPGImageName

["event[eventName]" : configuration.stringEventName,
"event[images][0][image][imageFile]" : self.imageTaken!,
"event[images][0][image][imageName]" : imageJPEGname,
]
var headers = [String:String]()
headers["Content-Type"] = "multipart/form-data"
let urlpath = URL_CreateEvent.stringByAppendingString("?access_token=\(gblConfiguration!.AppToken!.accessToken)")
var arrayImageURL : Array<NSURL> = []
self.view.showLoader()
Alamofire.upload(.POST, urlpath, headers: headers, multipartFormData: { (multipartFormData) -> Void in

for (key , value) in dictUpload {
if value.isKindOfClass(UIImage) {
if let image = value as? UIImage{

if let fileURL : NSURL = fileSaveToDirectory(image, name: imageJPEGname)
{
multipartFormData.appendBodyPart(fileURL: fileURL , name: key)
arrayImageURL.append(fileURL)
}
else {
assert(false, "Unable to save file-name \(imageJPEGname)")
}
}
}

}
let alert = UIAlertView.init(title: AppName, message: "Event Created!", delegate: nil

break

嗨！有沒有辦法如何獲得正確的路徑？在文檔目錄中顯式更正文件的路徑？ –
