- How to use ZipFile

ZipFile *zipFile = [[[ZipFile alloc] initWithFileAtPath:@"foo.zip"] autorelease];

// Open zip archive
if (![zipFile open]) {
	// Handle error
}

// Get file name list. 
// Hierarchy handling is unnecessary.
// File name includes pass separator, and list of file names gives back all file names.
NSArray *fileNames = [zipFile fileNames];
if (!fileNames) {
	// Handle error
}

// Get file contents.
// That will read all at a time, not suitable for huge file.
// For safety, please set maxLength.
NSData *data = [zipFile readWithFileName:@"baa.jpeg" maxLength:1024 * 1024];
if (!data) {
	// Handle error
}

// Close zip archive
[zipFile close];
