【问题描述】：
我一直在尝试根据特定条件实现条件转换，但我不知道我落后的地方。如果有人可以帮助我，那将不胜感激
以下是代码：-
有两个 segues 需要处理，segueOtp& segueError
@IBAction func btnToOtpScreen(_ sender: Any) {
let providedMarketingRef = txtMarketingRef.text
//let providedhopName = txtShopName.text
if((providedMarketingRef?.isEmpty)!)
{
displayAlertMessage(messageToDisplay: "Enter Your Marketing Reference")
}
else
{
let myUrl = URL(string: "http://kumbhkaran.co.in/ios_otp_check/request_sms.php");
//let myUrl = URL(string: "http://kumbhkaran.co.in/OTPCheck/request_sms.php");
var request = URLRequest(url:myUrl!);
request.httpMethod = "POST";
let postString = "email=\(Email)&mobile=\(UserName)&name=\(ShopName)"
request.httpBody = postString.data(using: String.Encoding.utf8);
let task = URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
DispatchQueue.main.async
{
//spinningActivity!.hide(true)
if error != nil {
self.displayAlertMessage(messageToDisplay: error!.localizedDescription)
return
}
do {
let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? NSDictionary
if let parseJSON = json {
var msg : String!
//getting json response
msg = parseJSON["message"] as! String?
print(msg)
if(msg == "SMS request is initiated! You will be receiving it shortly.")
{
//self.performSegue(withIdentifier: "segueOTP", sender: self)
self.GlobalSegue="segueOTP"
}
else if(msg == "Sorry! Error occurred in registration.")
{
//self.performSegue(withIdentifier: "segueError", sender: self)
self.GlobalSegue="segueError"
}
else if(msg == "Mobile number already existed!")
{
//self.performSegue(withIdentifier: "segueError", sender: self)
self.GlobalSegue="segueError"
}
else if(msg == "Sorry! mobile number is not valid or missing.")
{
//self.performSegue(withIdentifier: "segueError", sender: self)
self.GlobalSegue="segueError"
}
}
} catch{
print(error)
}
}
}
task.resume()
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if (GlobalSegue=="segueOTP")
{
let destViewController : OTPScreen = segue.destination as! OTPScreen
destViewController.Category = Category
destViewController.SubCategory = SubCategory
destViewController.ShopName = ShopName
destViewController.ManagerName = ManagerName
destViewController.ManagerMobile = ManagerMobile
destViewController.UserName = UserName
destViewController.Landline = Landline
destViewController.Email = Email
destViewController.Website = Website
destViewController.City = City
destViewController.Address = Address
destViewController.Area = Area
destViewController.Pincode = Pincode
destViewController.StartTime = StartTime
destViewController.EndTime = EndTime
destViewController.ShopStatus = ShopStatus
destViewController.HomeDelivery = HomeConsultancy
destViewController.Password = Password
destViewController.MarketingRef = txtMarketingRef.text!
destViewController.ImgShopName = ShopName
destViewController.OtherCategory = Other
destViewController.WorkerCount = WorkerCount
destViewController.latitude = lblLatitude.text!
destViewController.longitude = lblLongitude.text!
}
else
{
var _ : ErrorController = segue.destination as! ErrorController
}
} //ErrorController 和 Congratulations 是两个不同的视图，我想根据条件转移。
【问题讨论】：
-
您的问题到底是什么？发生什么了？你想发生什么？
-
检查 if else 条件，那些 segue 不起作用。应该在不同的条件下调用两个不同的segue
-
设置断点并单步执行您的代码。看起来不错，但可能没有满足您的条件。
-
你在
prepareForSegue做了什么？你能把代码分享给我们吗？ -
我已经分享了prepareForSegue的代码
