问题 I am working with Swift 3. In my code I am using Siri integration in Wallet App.I am getting an error in that App. I searched in google for it but I didn't find the solution for it. Here is my code: func createPath(_ points: NSArray) -> UIBezierPath { let path = UIBezierPath() var point = CGPoint() //CGPointMakeWithDictionaryRepresentation((points[0] as! CFDictionary), &point) point.makeWithDictionaryRepresentation((points[0] as! CFDictionary)) // In this line I am getting an error path.move

问题 I'm sure this question is asked before but I couldn't find a solution for it. I have a UITableViewController with static cells , I have 4 sections (so far) and each section only has 1 cell . this is a part of the first Cell of First section and this is the corresponding TableViewCell file, AllgemeineProduktdatenCell.swift class AllgemeineProduktdatenCell: UITableViewCell{ // MARK: - Outlets @IBOutlet weak var AngebotsnameTextF: UITextField! @IBOutlet weak var Referenznummer: UITextField!

问题 I'm working on a project coded in swift 3 and I have a UIButton inside a UITableViewCell where the image changes once the button is tapped. Though the selected buttons get selected as intended, once the UITableview scrolls the selected images gets disappear since the cells are been reused. As I'm new to programming having troubles of writing the logic. Help would much appreciate the code as bellow. CellFoRow func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) ->

Based on XCode 8 Warning

问题 This is how I saved the images let format = DateFormatter() format.dateFormat="MMMM-dd-yyyy-ss" let currentFileName = "\(format.string(from: Date())).img" print(currentFileName) // Save Images let fileMgr = FileManager.default let dirPath = fileMgr.urls(for: .documentDirectory, in: .userDomainMask)[0] let imageFileUrl = dirPath.appendingPathComponent(currentFileName) do { try UIImagePNGRepresentation(returnedImages)!.write(to: imageFileUrl) print("Image Added Successfully") } catch { print

问题 In my application I have a UIButton that is quite small, so I thought about increasing the hit area of it. I found an extension for that: fileprivate let minimumHitArea = CGSize(width: 100, height: 100) extension UIButton { open override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? { // if the button is hidden/disabled/transparent it can't be hit if self.isHidden || !self.isUserInteractionEnabled || self.alpha < 0.01 { return nil } // increase the hit frame to be at least

问题 I am trying to save information to my contacts through programming and everything goes successful, however when I try to save social profiles I get this SIGABRT ERROR: 2017-01-23 00:10:11.323693 FVSCANNER[765:154249] [MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles 2017-01-23 00:10:11.325124 FVSCANNER[765:154249] [MC] Reading from public effective user settings.

问题 I think my problem spans over multiple VC. In the table VC I perform a fetch request that returns an array of Floor objects. This entity has 2 attributes (floor number and number of rooms in floors). If I assign 2 floors (0 and 1) it works and prints them. The next VC contains a picker that displays the number of floors and a text box that is used to assign the number of rooms per floor. There must be a problem with this function because it gets called only if the first item of the picker is
