每次运行后，Xcode 6 都会在 iOS8 模拟器中重命名我的应用程序目录。

Question

提问by Joseph Toronto

I'm running Xcode 6 Beta 5 but this has been happening since the first beta. My app's directory in the simulator keeps being renamed after each run. It took me a while to figure this out. I'm using this to get the doc's dir reference.

我正在运行 Xcode 6 Beta 5，但这自第一个测试版以来一直在发生。每次运行后，我的应用程序在模拟器中的目录不断被重命名。我花了一段时间才弄清楚这一点。我正在使用它来获取文档的目录参考。

NSString *folder = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                        NSUserDomainMask,
                                                        YES) lastObject];

NSLog(@"Documents Dir: %@",folder);

Now for example on the first run it'll be:

现在例如在第一次运行时它将是：

/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/4B10C2E4-A5C3-4C64-93B1-4069FCCB9C46/Documents

/用户/乔伊/库/开发商/ CoreSimulator /设备/ 5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE /数据/容器/数据/应用/ 4B10C2E4-A5C3-4C64-93B1-4069FCCB9C46/文件

Second run now it's:

现在第二次运行是：

/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/7E9EB62D-115A-4092-AD23-CB6BA3E5E10F/Documents

/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/ 7E9EB62D-115A-4092-AD23-CB6BA3E5E10F/Documents

Third run:

第三次运行：

/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/EC8F41E8-52ED-4B10-9808-B3ACC46FC6AA/Documents

/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/ EC8F41E8-52ED-4B10-9808-B3ACC46FC6AA/Documents

This is wreaking havoc with my app because it stores path references for certain files within the app. It's not that my NSLog statement is returning incorrect results, I verified this is what happening in Finder. It's changing the name every time. Has anyone seen this happen? Is this a "feature" that I'm misunderstanding?

这对我的应用程序造成了严重破坏，因为它存储了应用程序中某些文件的路径引用。并不是我的 NSLog 语句返回了错误的结果，我验证了 Finder 中发生的情况。每次都改名字。有没有人看到这种情况发生？这是我误解的“功能”吗？

Turns out Xcode 6 does in fact change the app's UUID every run, and I'm in the wrong for storing absolute paths.

事实证明，Xcode 6 实际上每次运行都会更改应用程序的 UUID，而我在存储绝对路径方面是错误的。

USE SIMPHOLDERS

使用 SIMPOLDERS

I used this app on Xcode 5 opens the Documents folder, for the currently running app in the simulator, in Finder.

我在 Xcode 5 上使用了这个应用程序，在 Finder 中为模拟器中当前正在运行的应用程序打开了 Documents 文件夹。

not ready for Xcode 6 yet (as of sep 24 2014) but saves all this hassle.

尚未为 Xcode 6 做好准备（截至 2014 年 9 月 24 日），但省去了所有这些麻烦。

In Xcode 6 / iOS8 The bundle is now separate from the data./ The application GUID is regenerated between runs in Xcode (not sure why)

在 Xcode 6 / iOS8 中，捆绑包现在与数据分开。/ 应用程序 GUID 在 Xcode 中的运行之间重新生成（不知道为什么）

  DOCUMENTS DIR:/Users/gbxc/Library/Developer/CoreSimulator/Devices/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Data/Application/C220D351-0BE7-46BA-B35E-D16646C61A3F/Documents
mainBundlePath_:/Users/gbxc/Library/Developer/CoreSimulator/Devices/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Bundle/Application/12200D1D-9B67-408B-BCF7-38206CBE0940/myappname.app/BLANK_BLOG_SCALED.jpg

1. FIND THE DEVICES FOLDER in SIMULATOR

1. 在模拟器中找到设备文件夹

/Users/gbxc/Library/Developer/CoreSimulator/Devices/

open each /device.plist to see which GUID is which device in XCode - I think this is static

打开每个 /device.plist 以查看哪个 GUID 是 XCode 中的哪个设备 - 我认为这是静态的

3. FIND THE DEVICE you're running on iPad 2 - I think this is static

3. 找到您在 iPad 2 上运行的设备 - 我认为这是静态的

/Devices/AC79941F-EC56-495E-A077-773EEE882732

4. Find your application /Documents folder

4. 找到您的应用程序 /Documents 文件夹

/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Data/Application/C220D351-0BE7-46BA-B35E-D16646C61A3F/Documents

BEWARE the GUID C220D351-0BE7-46BA-B35E-D16646C61A3F is regenerated everytime the app is run in XCode 6

请注意，每次在 XCode 6 中运行应用程序时都会重新生成 GUID C220D351-0BE7-46BA-B35E-D16646C61A3F

 NSArray *paths_ = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        if(paths_){
            _docsDir = [paths_ firstObject];
            DebugLog(@"DOCUMENTS DIR:%@",_docsDir);         
        }else{
            ErrorLog(@"paths_ is nil - cant get Documents directory");
        }

MAIN BUNDLE path

主捆绑路径

NSString *mainBundlePath_ = [[NSBundle mainBundle] pathForResource:@"someimageinyourbundle" ofType:@"jpg"];
/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Bundle/Application/12200D1D-9B67-408B-BCF7-38206CBE0940/clarksonsiq.app/BLANK_BLOG_SCALED.jpg

NEVER CACHE THE PATH to /Documents between runs it will change.

永远不要在运行之间缓存到 /Documents 的路径，它会改变。

I was serializing it to a plist and couldnt figure out why they kept disappearing

我正在将它序列化到 plist 中，但无法弄清楚它们为什么不断消失

The GUID above /Documents keeps changing between runs but if you have /Documents open in Finder the folder stays open.

/Documents 上方的 GUID 在运行之间不断变化，但如果您在 Finder 中打开了 /Documents，则该文件夹将保持打开状态。

I can confirm that this is Xcode 6 related not iOS 8.

我可以确认这是 Xcode 6 相关而不是 iOS 8。

I have two development machines. On one of them I have Xcode 5. I was working all the time on that machine and my URL's were fine (photo app, photos are visible).

我有两台开发机器。其中一个我有 Xcode 5。我一直在那台机器上工作，我的 URL 很好（照片应用程序，照片可见）。

Yesterday I checked in form git my source on a machine with Xcode 6. I noticed that my photos are not visible any more, only photos that are created during that app session.

昨天，我在装有 Xcode 6 的机器上检查了表单 git my source。我注意到我的照片不再可见，只有在该应用程序会话期间创建的照片。

After little debugging, I realized that file:///var/mobile/Applications/B6A6BAEF-C90C-4A2A-93DB-E6700B88971F/Documents/ is changing on every app run.

经过一些调试，我意识到 file:///var/mobile/Applications/ B6A6BAEF-C90C-4A2A-93DB-E6700B88971F/Documents/ 在每次应用程序运行时都会发生变化。

All that time I am working with iOS 7 device.

一直以来我都在使用 iOS 7 设备。

I am going to check once more on a machine with Xcode 5 to confirm when I get my hands on it.

我将在装有 Xcode 5 的机器上再次检查以确认我何时可以使用它。

You need to to save only path inside DocumentDirectory(directory/file name), and add it to the DocumentDirectory every time you load the file...

您只需要在 DocumentDirectory（目录/文件名）中保存路径，并在每次加载文件时将其添加到 DocumentDirectory...

-(void)saveImage:(UIImage *)image{
NSData *pngData = UIImagePNGRepresentation(image);
NSString *pathInDocumentDirectory = [APP_DocumentDirectory stringByAppendingPathComponent:PROFILE_IMAGE_NAME];
NSString *filePath = [self documentsPathForFileName:pathInDocumentDirectory];
//Save pic file path - DirName/Filename.png
[XYZPreferencesHelper setUserImageFilePath:pathInDocumentDirectory];
 //Write the file
[[NSFileManager defaultManager] createFileAtPath:filePath contents:pngData attributes:nil];

}



-(void)loadSavedUserPicture{
//Load saved DirName/Filename.png
NSString *pathInDocumentDirectory = [XYZPreferencesHelper getUserImageFilePath];

if (pathInDocumentDirectory != nil){
    //Full path with new app Document Directory
    NSString *filePath = [self documentsPathForFileName:pathInDocumentDirectory];
    if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]){
        NSData *pngData = [NSData dataWithContentsOfFile:filePath];
        UIImage *image = [UIImage imageWithData:pngData];
        if (image != nil){
            userPicImageView.image = image;
        }

    }

 }
}



- (NSString *)documentsPathForFileName:(NSString *)name
{
NSString *documentsPath = [self createRestcallDirectoryIfNotExist];
return [documentsPath stringByAppendingPathComponent:name];
}



-(NSString *)createRestcallDirectoryIfNotExist{
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
path = [documentsPath stringByAppendingPathComponent:APP_DocumentDirectory];
NSError *error;
if (![[NSFileManager defaultManager] fileExistsAtPath:path])    //Does directory already exist?
{
    if (![[NSFileManager defaultManager] createDirectoryAtPath:path
                                   withIntermediateDirectories:NO
                                                    attributes:nil
                                                         error:&error])
    {
        NSLog(@"Create directory error: %@", error);
    }
}
return documentsPath;
}

每次运行后，Xcode 6 都会在 iOS8 模拟器中重命名我的应用程序目录。
