Unpacking a file on a device

Question

The following team worked great on Simulator. But this command does not work on devices.

#define kUnZipCommand @"unzip \"%@\" -d\"%@\""
NSString *anUnZipCommand = [NSString stringWithFormat:kUnZipCommand, aFileName, aDirectoryPath];       
system([anUnZipCommand UTF8String]);   

Any idea?

Answer 1

Call is system()not supported on the device due to the sandbox. To process Zip files you need to link to library .

Answer 2

You will need to use a framework like ZipKit .

Answer 3

I used NuZipin the past. You call it the same way you could call unzip on the command line:

[NuZip unzip:@"MyArchive.zip -d my_directory"];
