iPhone Unzip code

Question

Really stuck on trying to write code to unzip a file or directory on the iPhone.

Below is some sample code that I'm using to try and unzip a simple text file.

It unzips the file but its corrupt.

(void)loadView {      NSString *DOCUMENTS_FOLDER = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];     NSString *path = [DOCUMENTS_FOLDER stringByAppendingPathComponent:@"sample.zip"];      NSString *unzipeddest = [DOCUMENTS_FOLDER stringByAppendingPathComponent:@"test.txt"];        gzFile file = gzopen([path UTF8String], "rb");      FILE *dest = fopen([unzipeddest UTF8String], "w");      unsigned char buffer[CHUNK];      int uncompressedLength = gzread(file, buffer, CHUNK);      if(fwrite(buffer, 1, uncompressedLength, dest) != uncompressedLength ||     ferror(dest)) {         NSLog(@"error writing data");     }     else{      }      fclose(dest);     gzclose(file);   }

I wanted an easy solution and didn't find one I liked here, so I modified a library to do what I wanted. You may find SSZipArchive useful. (It can also create zip files by the way.)

Usage:

NSString *path = @"path_to_your_zip_file"; NSString *destination = @"path_to_the_folder_where_you_want_it_unzipped"; [SSZipArchive unzipFileAtPath:path toDestination:destination];
