问题 I have multiple links from imgur with HTTPS (e.g https://i.imgur.com/DMKPbRe.jpg). I'm using this as one of my background for my protoype app, but whenever I run it on my iPhone 7 physical device, the app crushes with error code 1200. Actual error is below: 2019-01-22 19:36:54.402391+0800 App[00000:0000000] Task <00000000000000000000>.<2> load failed with error Error Domain=NSURLErrorDomain Code=-1200 "An SSL error has occurred and a secure connection to the server cannot be made."

问题 I'm trying to import JSQMessagesViewController: import JSQMessagesViewController And it gives me the error 'no such module'. I've seen many people with this problem on the web but I can't find the solution. Here's my podfile: # Uncomment this line to define a global platform for your project platform :ios, ‘9.2’ # Uncomment this line if you're using Swift use_frameworks! target ‘IXODES’ do pod 'JSQMessagesViewController' pod 'Firebase' pod 'Firebase/Core' pod 'Firebase/Database' pod 'Firebase

问题 I've recently upgraded to Flutter the latest version. As a result, my app won't load and fails instantly. The error seems to be due to the Flutter version. I've tried to downgrade but this wasn't successful. Here's the output of the console. Running "flutter pub get" in source... Because every version of flutter_test from sdk depends on vector_math 2.1.0-nullsafety.3 and fstore depends on vector_math 2.0.8, flutter_test from sdk is forbidden. So, because fstore depends on flutter_test any

问题 The examples given on https://docs.unity3d.com/Manual/UnityWebRequest.html works on Windows Desktop, Windows Mobile, Android and even in the iOS editor as expected. But when I publish the app to the Apple App Store it fails to connect to the internet. Unlike the other platforms, there is no noticeable delay and it seems to fail immediately when a request is attempted. The error is: Unknown Error Is there any special way that I need to configure the XCode project to allow an iOS app to connect

问题 I have a commercial macOS app I distribute in the Mac App Store. Now at startup I check for the App Store receipt and exit with code 173 if it is not present. This brings up the App Store sign in dialog in order to get a receipt. I have always tested this with sandbox accounts but now I only get errors when I try to sign in with a sandbox account (or my real Apple ID). The issue emerges when I start from XCode as well as when I export the app as a development build. I have the following setup

问题 I'm using Xcode's debugger. While stopped at a breakpoint, is there a command I can type in the GDB command prompt to create a local variable? If so, how? Please provide an example. I know I can do it in the code and then recompile the program, but I'm looking for a faster way. 回答1: It's mentioned in the comments, but not as an answer: if you don't need to reference the variable in your code but just want to do some ad-hoc investigation, you can use Convenience Variables Start your variable

问题 Previously I am using UILocalNotification for reminder purpose in my application. But as above API is deprecated in iOS 10.0 now need to use UserNotifications Framework's UNNotificationRequest .
