Have you tried iterating through your directories and files in the bundle, library, documents and cache directory? – Longdrawnout

Yes, but i can't get the exact directories and file in the bundle. Can you pls help to find out..? – Morris

The files / directories in your bundle won't change, so you could "just" get the directory info of you xcode project and use that folder size as a starting point for your total space. And then increment it with the library, documents and cache folder. Maybe there is a better way, haven't got experience with this – Longdrawnout

Thank you @Longdrawnout , Let me try...! – Morris

see that link landonf.bikemonkey.org/code/iphone/… it may help you. – Fablan

Answer 1

Assuming you are developing for a jailbroken device (if not then it is impossible to access the applications on the device), the SpringBoard should have predefined methods for accessing the metadata of all the applications installed. If you look at headers of SBApplication.h then there are methods for getting the metadata.

    NSString *folderPath = "give application path here"

Example: NSString *folderPath =@"/private/var/mobile/Applications/2B63FD7F-2082-415D-A00C-F07C4BE281AA/Example.app";

    NSArray *filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];

    NSEnumerator *filesEnumerator = [filesArray objectEnumerator];
    NSString *fileName;
    unsigned long long int fileSize = 0;

    while (fileName = [filesEnumerator nextObject])

    {
        NSDictionary *fileDictionary = [[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES];

        NSLog(@" fileDictionary   %@",fileDictionary);

        fileSize += [fileDictionary fileSize];
    }

    NSLog(@" App Name and App size: %@ : %lld", folderPath,fileSize);

if you want to find all applications size, take all applications path in array, and write for loop statement for folder path

   NSArray *applicationsPath="Here array contain all applications path"
   for (int i=0; i<applicationPath.count; i++)
   {
    NSString *folderPath = [applicationPath objectAtIndex:i]

    NSArray *filesArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:folderPath error:nil];

    NSEnumerator *filesEnumerator = [filesArray objectEnumerator];
    NSString *fileName;
    unsigned long long int fileSize = 0;

    while (fileName = [filesEnumerator nextObject])

    {
        NSDictionary *fileDictionary = [[NSFileManager defaultManager] fileAttributesAtPath:[folderPath stringByAppendingPathComponent:fileName] traverseLink:YES];

        NSLog(@" fileDictionary   %@",fileDictionary);

        fileSize += [fileDictionary fileSize];
    }

    NSLog(@" App Name and App size: %@ : %lld", folderPath,fileSize);
   }

Answer 3

Unless the device is jailbroken, you will be unable to access each Application's folder programmatically.

This is because each iOS application operates in a sandboxed environment, meaning your application can ONLY access assets within this directory. If the device is jailbroken, this requirement is removed and you are granted full access to the device's disk.
