小编Ped*_*edi的帖子

我正在使用Swift进行iOS编程,我正在使用此代码移动UITextField,但它不起作用.我keyboardWillShow正确调用该函数,但文本字段不移动.我正在使用autolayout.

override func viewDidLoad() {
    super.viewDidLoad()
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillShow:"), name:UIKeyboardWillShowNotification, object: nil);
    NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("keyboardWillHide:"), name:UIKeyboardWillHideNotification, object: nil);
}

deinit {
    NSNotificationCenter.defaultCenter().removeObserver(self);
}

func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.CGRectValue() {
        //let contentInsets = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0)

        var frame = self.ChatField.frame
        frame.origin.y = frame.origin.y - keyboardSize.height + 167
        self.chatField.frame = frame
        println("asdasd")
    }
}

我正在尝试在Swift中上传带参数的图像.当我尝试这段代码时,我可以得到参数而不是图像

uploadFileToUrl(fotiño:UIImage){
    var foto =  UIImage(data: UIImageJPEGRepresentation(fotiño, 0.2))


    var request = NSMutableURLRequest(URL:NSURL(string: "URL"))
    request.HTTPMethod = "POST"

    var bodyData = "id_user="PARAMETERS&ETC""


    request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding);
    request.HTTPBody = NSData.dataWithData(UIImagePNGRepresentation(foto))
    println("miraqui \(request.debugDescription)")
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var HTTPError: NSError? = nil
    var JSONError: NSError? = nil

    var dataVal: NSData? =  NSURLConnection.sendSynchronousRequest(request, returningResponse: response, error: &HTTPError)

    if ((dataVal != nil) && (HTTPError == nil)) {
        var jsonResult = NSJSONSerialization.JSONObjectWithData(dataVal!, options: NSJSONReadingOptions.MutableContainers, error: &JSONError)

        if (JSONError != nil) {
            println("Bad JSON")
        } else {
            println("Synchronous\(jsonResult)")
        }
    } …

如何使用Swift创建自定义警报？我尝试从Objective c翻译指南但加载全屏布局

为了方便我可以加载透明背景的新布局我试试这个:

    listaalertviewcontroller.view.backgroundColor = UIColor.clearColor()
    let purple = UIColor.purpleColor() // 1.0 alpha
    let semi = purple.colorWithAlphaComponent(0.5)

    listaalertviewcontroller.view.backgroundColor = semi


    presentingViewController.modalPresentationStyle = UIModalPresentationStyle.CurrentContext

    self.presentViewController(listaalertviewcontroller, animated: true, completion: nil)

在动画中它是透明的,但是当动画结束时它是不透明的......我在视图中关闭了不透明的选项......我做错了什么？

我正在尝试解析来自php的信息,但我需要发送一个字典参数,所以我尝试了一些东西......我看到了教程,例子但我被卡住了所以我回到了开头:(这是什么好方法这样做？)

       func asd(){
    let urlPath = "http://xxxxx.php"

    let url: NSURL = NSURL(string: urlPath)

    let request = NSMutableURLRequest(URL: url)
    request.HTTPMethod = "GET"
    var parm = ["id_xxxx": "900"] as Dictionary


    //I THINK MY PROBLEM IT'S HERE! i dont know how to link parm with session, i try is with session.uploadTaskWithRequest(<#request: NSURLRequest?#>, fromData: <#NSData?#>) but doesn't work

    let session = NSURLSession.sharedSession()
    let task = session.dataTaskWithURL(url, completionHandler: {data, response, error -> Void in
        println("Task completed")
        if(error) {
            // If there is an error in …

我是iOs和swift的新手,我不知道如何以yyyy-mm-dd格式给出一天,并在一周中的某一天给出功能响应,例如:

2014-08-04 - >周一([0])

谢谢
