iOS开发之压缩与解压文件

Posted 2020-07-23 飞羽孟德

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zlib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];
