iOS 模拟器：无法硬链接复制。 我的文件系统中的路径错误？

Question

I am using Xcode Version 6.1 (6A1052d)

I am trying to launch an app on the simulator.

The first time it always works fine. If I want to launch a second time, I have an error (see log below). Then in iOS simulator I "Reset Content and Settings" and I can launch again successfully.

Given the error log, I think it must have something to do with a wrong path. The problem is I am bad with Mac filesystem and path linking, so your help would be much appreciated.

EDIT : Here is the info.plist.xml (generated by LibGDX if it matters)

<?xml version="1.0" encoding="UTF-8"?>

And my robovm.xml:

app.version=1.0
app.id=<my package name>.IOSLauncher
app.mainclass=<my package name>.IOSLauncher
app.executable=IOSLauncher
app.build=1
app.name=<my app name>

I have tried to identify more precisely the error thanks to the advice of Jeremy, in the system.log inside the folder of my virtual device. The system.log has a lot of entries around the time of the crash, so I might have missed something... Anyway I have found these potentials errors:

The original crash log from Eclipse console (device name folders are different as I have tested on multiple virtual devices, but the error is always the same)

Answer 1

I faced this error while leaving Build field blank using only Version on General tab. The error has gone after setting a build value and reinstalling the app.

Answer 2

I believe the issue is exacerbated if you change your app's Info.plist from one build to the next (such as revving CFBundleVersion or similar). If you do that, you should delete the app from the simulator between each launch (either via SpringBoard or using simctl) or just erase the sim device.

This issue should be addressed in recent iOS Simulator 8.2 betas that are in Xcode 6.2 betas. I think it was addressed in either beta2 or beta3, but I can't recall for certain.

Answer 3

This is indeed triggered by the order of certain keys in your app's Info.plist file and what seems to be a bug in the iOS simulator's installd process. installd sometimes seems to be unable to read the CFBundleShortVersionString and CFBundleVersion values. I've found that if RoboVM makes sure to always move those values first in the Info.plist it writes out we prevent the bug in installd from being triggered. We have now implemented this workaround in RoboVM (see issue #771 ) and it will be in the next nightly build (the 20150222 build) and in the next release.

Nightly builds of RoboVM can be downloaded from http://download.robovm.org . To install a nightly build of the Eclipse plugin you should use the update site

http://download.robovm.org/nightlies/eclipse/site.xml

Nightly SNAPSHOT builds of the RoboVM Maven and Gradle plugins are pushed to Maven Central.

Answer 4

Find the InfoPlist.strings files. And check if the version of "CFBundleShortVersionString" = "1.1"; coincides with the version of your app in Info.plist

Answer 5

I encountered the same error using Xcode 8.2.1. Changing the order of items in the Info.plist did not help in my case. But it did lead me towards the solution. I had changed both CFBundleShortVersionString and CFBundleVersion from 3.0.0 to 3.0.1, BUT I HAD FORGOTTEN to also change to 3.0.1 in the localized and base InfoPlist.strings files. Doing that, fixed the problem.

Answer 6

Option-1: 1.Goto "General Setting" by clicking on the project name on left side bar. 2.Change the Bundle Identifier name to "com.release.ABC" (ABC may be any other name. It's better to replace ABC with your APP Name) 3. Now run it and Enjoy.

Option-2: 1.Open Simulator. 2.Remove all apps installed by user. 3.Run your App and Enjoy. NB: It has a demerit that every time you clean the simulator and then after, you will able to load your app.

Answer 7

This fixed it for me:

SIMULATOR_NAME="iPad Air 2"
# Erase a device's contents and settings
xcrun simctl erase "${SIMULATOR_NAME}"

Thanks to https://encyclopediaofdaniel.com/blog/xcode-6-reset-simulators-from-the-command-line/ for the explanation!

My env: xcode 8.3.1 iOS 10.3 (14E269) SIMULATOR_NAME="iPad Air 2"

Answer 8

I had this issue too for a long time. I tried most of these solutions. I'm sure they worked for some people, but not for me...

Then I noticed if you go to Project Settings -> Build Phases -> Embed Frameworks there is a flag for Copy only when installing ... I ticked it. This problem went away.

Answer 9

I experienced this issue in a multi-target project. After duplicating a target I forgot to change the "Product Bundle Identifier". Once I changed this parameter into a unique value (see tab "Build Settings"), the error disappeared.

EDIT

After changing the "Product Bundle Identifier" you must erase all content and settings from the simulator and clean your build folder in Xcode (Cmd+Shift+K).

I'm using Xcode 10.1.

Answer 10

In my case, it was a file that was not included in the application that had the emulator. Just remove the emulator app, clean, recompile and start it. When adding the file, and make sure the "Copy items if necessary" check box is enabled

Answer 11

This happened to me when duplicating a target, and forgot to add the new target to the pods file.

So my fix was editing the podfile to also include the new target, and running 'pod install'.

Answer 12

The issue in our case was using a Swedish "Å" character in the Product Name. Had to use a user defined setting for the display name instead, then uninstall the app from the simulator and probably also a Clean Build Folder.

Answer 13

In my case this error is caused by unicode character in Product Name

Use Ascii for Product Name and error gone (Note that Display Name is app name displayed below app icon so don't worry to change Product Name )

Answer 14

Select Project from Navigation window -> TARGET -> General -> Build or Version

确保两个字段都填充了一些值。
