Zip Archive read/write framework in Cocoa

CocoaMediumZipArchive read/writeFrameworkIs the content to be introduced in this article.ZipRead/writeFramework:Zip-Framework. ThisFrameworkSupports reading and writing directly in the programZipFiles in the archive, instead of using NSTask to execute the unzip command line.

CocoaRead/write is not providedZipGZIP:/usr/include/zlib. h, but it has limitations.Zip frameworkThis function is well implemented. ThisFrameworkUse Objective-C for writing, so it can be conveniently called in the program. In theory, it can also be used for the iPhone. If anyone is interested, try it ).

Usage:

 
 

  
  
#import <stdio .h> 
  
  
#import <zip /ZipArchive.h> 
  
  
   
  
  
ZipArchive *zip = [[ZipArchive alloc] initWithFile:@"…"];  
  
  
if (!zip) {  
  
  
    NSLog(@"File could not be opened");  
  
  
}  
  
  
   
  
  
FILE *fp = [zip entryNamed:@"README.txt"]; // open stream to file README.txt in archive  
  
  
if (!fp) {  
  
  
    NSLog(@"Not a file or not available in the archive");  
  
  
}  
  
  
   
  
  
NSArray *allEntries = [zip entries];  
  
  
// for example: [@"README", @"COPYING", @"src/", @"src/main.c"]  
  
  
   
  
  
[zip release];  
  
  
   
  
  
// Autoreleased version  
  
  
ZipArchive *autoreleasedZip = [ZipArchive archiveWithFile:@"…"];  
  
  
</zip></stdio> 
 
 

In this way, you can obtainZipThe file pointer in the package, which can be read directly. (Currently, only fread operations are supported)
