问题 Having a problem following a few guides, specifically http://blog.originate.com/blog/2014/04/22/deeplinking-in-ios/ I'm setting the url scheme and it's working well to launch the app from another app, but passing in the host or url are not working as it seems it should. I'm using storyboards and interface builder for all the view layouts. The guide shows this openURL in appDelegate: -(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *

Controlling which view controller loads after receiving a push notification in SWIFT

由 半世苍凉 提交于 2019-11-27 09:52:04
问题 Once I receive a push notification and swipe to open it, it just opens my app and not the VC I want. So my question is how do I load the VC I want? I know if the app is open I would move the VC over to another inside the didReceiveRemoteNotification but how do I do it if the app isn't open? or if it is in background mode? Also I have TWO different push notifications, so therefore I need it to move ONE of TWO different VCs. How can I tell the difference between different push notifactions?

问题 Because UILocalNotification is not being displayed while the application is in active stat, I'm trying to configure an UIAlertController and playing a little sound when it appears.

Here is what I have so far : //... class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(application: UIApplication,

How to present a splash/login view controller using storyboards

由 一笑奈何 提交于 2019-11-27 07:09:06
I've seen this question in various forms without a clear answer. I'm going to ask and answer here. My app needs to do work on startup... inits, a few network calls, login, etc. I don't want my main view controller working until that's done. What's a good pattern for doing this? Requirements: iOS5+, storyboards, ARC. the main vc's view cannot appear until the startup work is done. want a choice of transition styles to the main vc when the startup work is done. want to do as much layout as possible in storyboard. the code should be cleanly contained somewhere obvious. EDIT, July 2017 Since the

Getting location for an iOS app when it is in the background and even killed

由 女生的网名这么多〃 提交于 2019-11-27 06:54:05
问题 My app needs to get the user's location when app is active and when it's inactive and killed. When the user's location is near to a store the app has to send a local notification. I'm not sure what exactly is happening, but I'm not able to make my app get the location in the background and wakes it up when is killed. I have a location manager (singleton, used for boths cases whenInUse and Always), and I have both NSLocationAlwaysUsageDescription and NSLocationWhenInUseUsageDescription defined

Swift – Instantiating a navigation controller without storyboards in App Delegate

由 情到浓时终转凉″ 提交于 2019-11-27 05:25:35
问题 I'm rebuilding an app without storyboards and the part of it that I'm having the most trouble with is navigating view-to-view programatically. Few things are written out there which don't use storyboards, so finding an answer for this has been tough. My problem is pretty simple. I have my ViewController and my SecondViewController and I want to push from the former to the latter. In AppDelegate : func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions:
