Do you have any suggestions? if UIDevice.currentDevice().userInterfaceIdiom == .Pad { let textToShare = textViewOne.text let objectsToShare = [textToShare] let activityVC = UIActivityViewController(activityItems: objectsToShare,

问题 I have tableview... 1 table showing a new modal window and when I press the button I want to dismiss the modal window and push to VC.

问题 I am trying to wake up the iOS parent app by sending a message from watchkit extension. This though does only work when below sendMessage function is called from the watchApp / ViewController. When it is called from ComplicationController, the message is sent, but the iOS parent app does now wake up. Any advice appreciated. (please any code reference in Swift) Here the simplified code: In AppDelegate and ExtensionDelegate: override init() { super.init() setupWatchConnectivity() } private func

问题 I want to write an extension for array to check if an array contains all the elements of another array, in my use case it's string objects but I keep get: Cannot convert value of type 'T.Generator.Element' to expected argument type '@noescape _ throws -> Bool' in the line self.contains(item) the error in about item here is my code: extension Array { func containsArray<T : SequenceType where T.Generator.Element : Equatable> (array:T) -> Bool{ for item:T.Generator.Element in array{ if !self

问题 So I have adjusted my games ball type from a shape to an image which forced me to redo the physics of my game. I am new to swift and have struggled with fixing my collisions in my swift game. class GameScene: SKScene, GameDelegate, SKPhysicsContactDelegate { var ball: Ball! let ballSpeedX = CGFloat(500) //ball = Ball(imageNamed:"colorBall.png") enum CollisionTypes: UInt32 { case Floor = 1 case Ball = 2 } // board let boards = Boards.make(CollideType.BoardStart.rawValue) var lastBoard: SKNode?

问题 (programming in swift 2) I have a UITextField that when the user types into it should be automatically converted to lower case WHILE typing (so NOT after form validation). I have gotten this far: func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool { //only convert to lowercase for username field if textField == textFieldUsername { //let stringRange = NSRange(location: range.location, length: range.length) let

问题 I've got a project using Mapbox. The code base is mixed objC and Swift code. The class using Mapbox is written in Swift but is exposed to legacy objC code. I'm using !use_frameworks in my pod file to be able to use Swift pods as well. The problem I'm facing is that generated -swift.h file is wrong. This is the problematic bit: #if defined(__has_feature) && __has_feature(modules) @import ObjectiveC; @import Mapbox; @import CoreGraphics; @import Foundation; @import UIKit; #endif __has_feature
