ziparchive是基于开源代码”MiniZip”的zip压缩与解压的Objective-C 的Class,使用起来非常的简单
方法：从http://code.google.com/p/ziparchive/ 上下载ZipArchive.zip，解压后将代码加入工程中，并且把libz.dylib库添加到工程中
使用方法：
1. 压缩:ZipArchive可以压缩多个文件,只需要把文件一一addFileToZip即可.
ZipArchive* zip = [[ZipArchive alloc] init]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil; NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ; NSString* image1 = [documentpath stringByAppendingString:@"/image1.jpg"] ; NSString* image2 = [documentpath stringByAppendingString:@"/image2.jpg"] ; BOOL ret = [zip CreateZipFile2:l_zipfile]; ret = [zip addFileToZip:image1 newname:@"image1.jpg"]; ret = [zip addFileToZip:image2 newname:@"image2.jpg"]; if( ![zip CloseZipFile2] ) { l_zipfile = @""; } [zip release];
2. 解压缩:
ZipArchive* zip = [[ZipArchive alloc] init]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil; NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ; NSString* unzipto = [documentpath stringByAppendingString:@"/test"] ; if( [zip UnzipOpenFile:l_zipfile] ) { BOOL ret = [zip UnzipFileTo:unzipto overWrite:YES]; if( NO==ret ) { } [zip UnzipCloseFile]; } [zip release];
