我正试图在App上使用Parse,我是swift的新手.但我下载了Xcode 7,似乎缺少libz.dylib libsqlite3.dylib,当我编译和构建它成功完成但Parse没有显示任何数据保存.我尝试将-lz和-lsqlite3添加到"其他链接器标志"但尚未能解决问题.有谁知道如何添加这些库？
我正在尝试制作一个正在运行的应用程序，用户可以在该应用程序上注册并拥有自己的帐户。但是我在用户注册时使用默认的parse signUpViewController。我在Parse的User类中有一个完成马拉松的列。在为新用户注册该列的值时，未定义，是否可以设置用户注册时的默认值？在下一节中可以做到吗？
func signUpViewController(signUpController: PFSignUpViewController, didSignUpUser user: PFUser) {
self.dismissViewControllerAnimated(true, completion: nil)
}
我正在使用swift，xcode7和parse作为后端。
我目前正在使用bootstrap 4.我阅读了bootstrap文档,我目前正在尝试合并标签,但他们没有切换我的代码如下:

我试图让倒数计时器从60秒开始倒计时,然后在达到0时停止.但是对于计时器一直持续到负秒.任何建议表示赞赏.码:
@IBOutlet var timeCounter: UILabel!
var second = 60
var timer = NSTimer()
var timerRunning = true
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setTimer()
timerCounting()
}
func setTimer(){
second -= 1
timeCounter.text = "\(second)"
}
func timerCounting(){
if(timerRunning == true){
timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector("setTimer"), userInfo: nil, repeats: true)
timerRunning = true
if second == 0 {
timerRunning = false
timer.invalidate()
}
}
}
我正在尝试将 JSON 文档中的日期格式化为“mm-dd-yyyy”格式。我有以下数据：
{"data":[{
"id": 123,
"url": "https://www.google.com",
"title": "The Google link",
"created_at": "2017-08-29T04:00:00.000Z",//date to format
"sent": true,
"alternative": "https://google.com",
"things": [],
"description": [
"search",
"lookup"
],
"company": "Alphabet"
}]}
这是我的结构：
struct Sitedata: Decodable{
let data: [site]
}
struct site: Decodable {
let id: Int
let url: String
let title: String
let created_at: String
let sent: Bool
let alternative: String
let things: [String]
let description: [String]
let company: String
}
let sites = try JSONDecoder().decode(Sitedata.self, from: data)
我尝试了以下方法，但它产生了nil： …
我试图将Textview的值更改为我正在查询解析的某些信息,但由于某种原因,.setText它没有生效.
我尝试谷歌搜索,但.getString也无法正常工作.我是Parse任何建议的新手？
