release

问题 What is the difference between these two code snippets: object = nil; [object release] Vs [object release]; object = nil; which is the best practice ? 回答1: object = nil; [object release] Don't do that. You are sending a release message on a nil object that will just do nothing. But the object that was referenced by your object is still in memory because it has never received a release message. [object release]; object = nil; Here you release the object, and for convenience and security, you

问题 Does Github offer the option to create release-page for a project? I've noticed it let you create different tag for the source, but couldn't find the UI/web where I can add release notes, built package(s) and all that. 回答1: Update 2d July 2013, you now can define a release . Releases , a workflow for shipping software to end users. Releases are first-class objects with changelogs and binary assets that present a full project history beyond Git artifacts. They're accessible from a repository's

问题 I want to use Gradle Release Plugin in Android Project . I configured it and everything is okay, except one thing: Gradle Release Plugin changes project version in gradle.properties file in one of its tasks, but this change does not affect Android Project's versionName , because as I found with using println() gradle initialising it before running any tasks. Is there a way to change Android Project versionName in some gradle task after it was initialised? Here is part of my build.gradle

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Debug/Release difference I want to know what do these two mean: Debug build and Release build and what is the difference between both. Which one should I use (I mean which are the suitable conditions for each one) and which build actually I am using now if I make a simple C++ project in Visual studio. [If I do not change any projects settings] I am asking this because I am trying to make a GUI using wxWidgets 2

问题 I have an ASP.NET Web Application project that connects to a remote database via the Entity Framework. During debugging (eg running the project on my local computer), the IP address to the database is different than during release (eg after uploading the project to my webserver and running it from the browser). Until now I have always manually changed the database connection string in the Web.config file to switch between the two (basically I had to connection strings, one named 'Debug' and

问题 How can I target a previous version of iOS in XCode4? My app is building only for iOS 4.3 devices and I'd like users with iOS 3.0 installed to be able to run the app as well. 回答1: Select the project in the Project Navigator and the then the target in the detail view. Under the summary tab you have the Deployment Target. Set it to 3.0. Alternatively you can set the iOS Deployment Target in the build settings. Both ways change the same parameter, it's just two different ways to access it. This

问题 final update: now everything works; while before I was not adding internet permission and the app worked perfectly (contacting API and everything), since the update I have to explicitly modify the manifest. Easy fix actually: manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.xxx.xxx"> <uses-permission android:name="android.permission.INTERNET"/> <application android:name="io.flutter.app.FlutterApplication" android:label="xxx" android:icon="@mipmap/ic_launcher">

问题 My project depends on a 3rd party library that only has snapshots in its maven repository (no releases, which seems strange, but that's how it is). Every time I do a full build (and clean my local .m2 repository) maven will obviously go and grab the latest build. My repository proxies the one with the snapshots in it, is there anyway to tell my repository to stop pulling new versions and basically just keep the current version? I really don't want to be pulling a new build every night. The
