Swift 2.1 [UInt8] --utf8--> String?

由 不羁的心 提交于 2019-12-17 14:54:08
问题 I know questions like this exist on both Stack Overflow and elsewhere. But it seems to have evolved a lot as well. Given a list of UInt8 (a swift byte array basically), what is the easiest/idiomatic way to covert it to a swift String ? I'm particularly interested in the method that doesn't use NSData/NSString, since if Santa brings Swift to the world of Linux, it will undoubtedly be without the NS libraries, and I'd like to know how to do it in just Swift. 回答1: let buffUInt8: Array<UInt8> =

Get the start point and end point of the UIPanGestureRecognizer in Swift

由 只愿长相守 提交于 2019-12-14 02:37:06
问题 I'm using UIPanGestureRecognizer on a project, and I want to take the starting point and the end point. I tried to do for touchesBegin , but did not get a code that does what I need. How can I get the start point and end point of the UIPanGestureRecognizer ? 回答1: For your case, you might want to include the code inside my function into your IBAction for the panGesture. Here I've created a view, but otherwise you would just be referring to self.view instead of view . var view = UIView() func

Trying to extend IntegerType (and FloatingPointType); Why can't all Int types be converted to NSTimeInterval

问题 (This probably needs a better title...) I would like to have a set of accessors I can use in code to quickly express time durations. E.g: 42.seconds 3.14.minutes 0.5.hours 13.days This post illustrates that you can't just do it with a simple new protocol, extension, and forcing IntegerType and FloatingPointType to adopt that. So I thought I'd just go the more redundant route and just extend IntegerType directly (and then repeat the code for FloatingPointType ). extension IntegerType { var

UITableview reloading tableview and cell

问题 I am trying to reload my table view using self.tableView.reloadData() It works properly if I'm loading static datasource using array. Everything work properly. But when I try to use my query function with parse, it loads a new cell but the contents of the tableview cell doesn't change. If I re-open the app, the cells will update properly. override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cellIdentifier =

问题 Every-time I open the app, it returns 6 rows, even if I created a new user with 1 post, it returns 6 rows. plus when I pull to refresh the data remains the same, I have to reopen the app again to see the new data added. this is my code below, override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete implementation, return the number of rows if PFUser.currentUser()?.objectId == nil{ PFUser.currentUser()?.saveInBackgroundWithBlock({

viewWillTransitionToSize causes non-rotating view controller to resize and reposition

由 对着背影说爱祢 提交于 2019-12-08 02:29:09
问题 A lot of people have discussed techniques for mimicking the native iOS camera app (where the UI elements pivot in-place as the device rotates). I actually asked a question about it before here. Most people have you lock the orientation of the UI, but then force a transformation on just the elements that you want to pivot. This works, but the elements don't pivot with the smooth animations you see in the native iOS app and it leads some issues. Specifically, part of my interface allows users

I'm developing an app for iPad Pro. In this app, containerView use to add additional views and interact with them. First, I created a protocol: protocol DataViewDelegate { func setTouch(touch: Bool) } Then, I created my first view controller import UIKit class ViewController: UIViewController, DataViewDelegate { @IBOutlet var container: UIView! @IBOutlet var labelText: UILabel! override func viewDidLoad() { super.viewDidLoad() } func setTouch(touch: Bool) { if touch == true { labelText.text = "Touch!" } } } And finally, I created a view that will be embedded in containerView. import UIKit
