问题 I have a block that is passing data in that I'd like to convert to an array of array of floats -- e.g. [[0.1,0.2,0.3, 1.0], [0.3, 0.4, 0.5, 1.0], [0.5, 0.6, 0.7, 1.0]]. This data is passed to me in the form of data:UnsafeMutablePointer<UnsafeMutableRawPointer> (The inner arrays are RGBA values) fwiw -- the block parameters are from SCNParticleEventBlock How can I dereference data into a [[Float]]? Once I have the array containing the inner arrays, I can reference the inner array (colorArray)

问题 I literally could not find a single tutorial that showed me how to build an app that uses static cells; with clickable cells. Based on few out dated posted and object-c answers, I've put something together. My issue is, when I click on a cell, I get staticDemoTableCell is has no member present . I have embedded a Table Controller in my UIViewController. For that cell (only one so far), I've created a class: class staticDemoTableCell: UITableViewCell, UITableViewDelegate { @IBOutlet weak var

问题 I am running a school project and I am new from swift3. By searching, I know how to pass a data from one view to anther: Passing data from a tableview to webview In the post above, he is using http get request to pass data to website, then reload the webivew: let URL = NSURL(string: "https://www.example.com?data=\(passData)") webView.loadRequest(NSURLRequest(url: URL! as URL) as URLRequest) I see some useful links like about code with http post request in here: HTTP Request in Swift with POST

问题 I need to translate this function into swift. Basically what does it get the 'n' day of the current week. So for example if i use it with NSDate().getWeekDay(0) it gives me Sun 11 Sept, and so on. But seems rangeOfUnit no longer exists in Swift-3. This was my previous implementation in Swift-2 extension NSDate { func getWeekDay(day: Int) -> NSDate { var beginningOfWeek: NSDate? NSCalendar.currentCalendar().rangeOfUnit(NSCalendarUnit.WeekOfYear, startDate: &beginningOfWeek, interval: nil,
