how to check free disk space on IOS , please help me .

I need to download AssetBundle to my game, so I first need to check how many disk space left on device .
I just tryed call Caching.spaceFree , but it returns 9223372036854775807 , its very wrong .

So I tryed to do this by myself . On Android , I implement this by calling AndroidJavaScript.

But I can't find solution on IOS , can anyway help me with this ? thx

 

I think I need use NSFileManager to do this, but it is a IOS api, how can I access it in Unity?

 

native plugin could do it real quick.

 

Lxl2013,

Did you find a way to make it work? I am also looking for the same thing ...
Graham, I saw your link, but unfortunately I am not experienced enough to understand how to use the API with NSFileManager.

I have imported the free version of U3DXT and it seems to be enough to be able to access U3DXT.iOS.Native.Foundation;
But from there, I have no clue how to convert this : http://stackoverflow.com/questions/...ble-free-disk-space-on-the-iphone-ipad-device into something that works in c#.

Any help would be appreciated

Thanks.

 

I don't bump most of the time But this is really annoying me
Anyone knows how to convert the script below to make it work in c# ?
I am using the API from U3DXT.

Code (csharp):

1.  
2. -(uint64_t)getFreeDiskspace {
3.     uint64_t totalSpace = 0;
4.     uint64_t totalFreeSpace = 0;
5.     NSError *error = nil;  
6.     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);  
7.     NSDictionary *dictionary = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[paths lastObject] error: &error];  
8.  
9.     if (dictionary) {  
10.         NSNumber *fileSystemSizeInBytes = [dictionary objectForKey: NSFileSystemSize];  
11.         NSNumber *freeFileSystemSizeInBytes = [dictionary objectForKey:NSFileSystemFreeSize];
12.         totalSpace = [fileSystemSizeInBytes unsignedLongLongValue];
13.         totalFreeSpace = [freeFileSystemSizeInBytes unsignedLongLongValue];
14.         NSLog(@"Memory Capacity of %llu MiB with %llu MiB Free memory available.", ((totalSpace/1024ll)/1024ll), ((totalFreeSpace/1024ll)/1024ll));
15.     } else {  
16.         NSLog(@"Error Obtaining System Memory Info: Domain = %@, Code = %@", [error domain], [error code]);  
17.     }  
18.  
19.     return totalFreeSpace;
20. }
21.  

Thanks,
Laurel.

Has anyone made this work in IOS? on Android i have no issues but on IOS i get an undefined symbol error when building on Xcode (Undefined symbol: __iDiskSpace_FreeSpace) as well as during gameplay in the editor (DllNotFoundException: diskUtils)

 

We had this running on Unity 2020.3 on M1 macbooks but as soon as we upgraded to Unity 2021.3 it stopped working with that same DllNotFoundException

 

@RandomUnityDev123 did you find a solution? how did you make it work on m1?
