每次运行后，Xcode 6会继续在iOS8模拟器中重命名我的应用程序目录 .

  事实证明Xcode 6实际上每次运行都会更改应用程序的UUID，而我存储绝对路径的错误 .

  USE SIMPHOLDERS

  我在Xcode 5上使用这个应用程序，在Finder中为模拟器中当前运行的应用程序打开Documents文件夹 .

  http://simpholders.com/

  还没有为Xcode 6做好准备（截至2014年9月24日），但保存了所有这些麻烦 .

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

  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

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

  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

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

  4. Find your application /Documents folder

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

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

  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

  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.

  我把它连载到一个plist并且无法弄清楚它们为什么一直在消失

  上面的/ GUID在运行之间不断变化但是如果在Finder中打开/ Documents文件夹保持打开状态 .

  Free Solution

  使用开源库OpenSim . OpenSim是SimPholders的开源替代品，用Swift编写 .

  Paid Solution

  使用SimPholder应用程序了解当前的应用程序位置 .

  

  对于xcode 6.0>

  下载SimPholder 2.0 alpha 2

  ---

  对于xcode 5.1 <

  下载SimPholders 1.5

  我可以确认这是Xcode 6与iOS 8无关 .

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

  昨天我在带有Xcode 6的机器上检查了git我的源代码 . 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 .

  经过一些调试，我意识到文件：/// var / mobile / Applications / B6A6BAEF-C90C-4A2A-93DB-E6700B88971F / Documents /正在改变每个应用程序运行 .

  我一直在使用iOS 7设备 .

  我将再次在带有Xcode 5的机器上进行检查，以确认我什么时候拿到它 .

  您需要在DocumentDirectory（目录/文件名）中仅保存路径，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;
  }
