问题 I have vidoe playing in landscape mode. And the view only rotate between landscapeLeft and landscapeRight when the device orientation changes. That's to say there is no portrait mode when playing the movie. What's more apart from the movie view, other views are portraint mode, so the app config is portrait. How can I make the movie view only rotate in the landscape mode. Here is a part of my code. appdelegate, internal var shouldRotate = false func application(_ application: UIApplication,

Trouble refreshing Spotify token iOS SDK

由 蓝咒 提交于 2019-12-23 03:59:27
问题 I'm confused as how I use the refresh token service. In my app there is a section with many playlists. When the user clicks on the playlist it runs this code: func checkAuth() { print("checking auth") let auth = SPTAuth.defaultInstance() //print(auth!.session.isValid()) if auth!.session == nil { print("no auth") if auth!.hasTokenRefreshService { print("refresh token if session == nil") self.renewTokenAndShowPlayer() return } else { self.performSegue(withIdentifier: "LoginControllerSegue",

Swift 3 and JSON – Updating the database by running a URL in the background

由 青春壹個敷衍的年華 提交于 2019-12-23 03:17:08
问题 1. Clicking the link causes a database update. There is a certain link I have access to (let's pretend it's www.google.com), such that when I open it up in my browser, it updates a certain section of the JSON code in my database. Based on the numbers that make up a portion of the link, it adjusts a certain value in the data. 2. How do I run this link in the background of my iOS app? I need to be able to "open" this link within the app, without actually opening up a UIWebview and visually

How to exit a runloop?

由 北城余情 提交于 2019-12-23 03:06:24
问题 So, I have a Swift command-line program: import Foundation print("start") startAsyncNetworkingStuff() RunLoop.current.run() print("end") The code compiles without error. The async networking code runs just fine, fetches all its data, prints the result, and eventually calls its completion function. How do I get that completion function to break out of above current runloop so that the last "end" gets printed? Added: Replacing RunLoop.current.run() with the following: print("start") var
