iOS开发之解压缩zip文件

转载自:   http://blog.sina.com.cn/s/blog_833996210100udkl.html

从http://code.google.com/p/ziparchive/ 上下载ZipArchive.zip，解压后将代码加入工程中，把zlib库添加到工程中

压缩

1.    ZipArchive* zip = [[ZipArchive alloc] init];
2.          
3.    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
4.    NSString *documentPath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
5.    NSString * zipFile = [dcoumentpath stringByAppendingString:@"/images.zip"] ;
6.          
7.     NSString *image1 = [dcoumentpath stringByAppendingString:@"/犬夜叉.jpg"] ;   
8.     NSString *image2 = [dcoumentpath stringByAppendingString:@"/杀生丸.jpg"] ;      
9.          
10.     BOOL result = [zip CreateZipFile2:zipFile];
11.     result = [zip addFileToZip:image1 newname:@"犬夜叉.jpg"];
12.     result = [zip addFileToZip:image2 newname:@"杀生丸.jpg"];
13.     if( ![zip CloseZipFile2] ){
14.               zipFile = @"";
15.     }
16.     [zip release];

1. 解压缩
2.     ZipArchive* zip = [[ZipArchive alloc] init];
3.     NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
4.     NSString *documentPath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
5. 1.     NSString* zipFile = [dcoumentpath stringByAppendingString:@"/images.zip"] ;
   2.     NSString* unZipTo = [dcoumentpath stringByAppendingString:@"/images"] ;
   3.     if( [zip UnzipOpenFile:zipFile] ){
   4.            BOOL result = [zip UnzipFileTo:unZipTo overWrite:YES];
   5.            if( NO==result ){
   6.                       //添加代码
   7.            }
   8.           [zip UnzipCloseFile];
   9.      }
   10.      [zip release];
