After each launch, Xcode 6 renames the directory of my application in the iOS8 simulator.

Question

I am running Xcode 6 Beta 5, but this is happening with the first beta. My application catalog in the simulator continues to be renamed after each launch. It took me a while to figure this out. I use this to get the dor dir link.

NSString *folder = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]; NSLog(@"Documents Dir: %@",folder); 

Now, for example, at the first start it will be:

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

The second launch now is:

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

Third launch:

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

This harms how with my application, because it stores links to paths for certain files in the application. This does not mean that my NSLog statement returns incorrect results, I confirmed that this happens in the Finder. He changes the name every time. Has anyone seen this? Is this a “feature” that I misunderstand?

Answer 1

It turns out that Xcode 6 really changes the application UUID every time, and I am mistaken for storing absolute paths.

USE SIMPHOLDERS

I used this application on Xcode 5 by opening the Documents folder for the current application in the simulator in Finder.

http://simpholders.com/

not ready for Xcode 6 yet (starting with sep 24 2014), but it retains all these problems.

In Xcode 6 / iOS8, the package is now separated from the data. / 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 DEVICE FOLDER IN THE SIMULATOR

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

open each /device.plist file to find out what GUID this device is in Xcode - I think it's static

3. FIND THE DEVICE you are running on iPad 2 - I think it's static

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

4. Find the "Application / Documents" folder

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

CAUTION GUID C220D351-0BE7-46BA-B35E-D16646C61A3F is restored every time the application starts in Xcode 6

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

The 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 TELL THE WAY TO / Documents between launches will change.

I serialized it to plist and couldn't understand why they kept fading

The specified GUID / Documents are constantly changing between runs, but if you have / Documents open in the Finder, the folder remains open.

Free solution

Use the open source library OpenSim . OpenSim is an alternative to Open Source for SimPholders, written in Swift.

Paid solution

Use the SimPholder app to find out the current location of the app.

Answer 4

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

I have two machines for development. On one of them I have Xcode 5. I worked all the time on this machine, and my URL was right (photo application, photos are visible).

Yesterday I checked in git form my source on a machine with Xcode 6. I noticed that my photos are no longer visible, only photos created during this application session.

After a little debugging, I realized that the file: /// var / mobile / Applications / B6A6BAEF-C90C-4A2A-93DB-E6700B88971F / Documents / changes every time the application starts.

All this time I have been working with an iOS 7 device.

Once again I want to check on a machine with Xcode 5 to confirm when I receive it.

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

 -(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; }
