如何使用“ZipArchive库”压缩文件在iphone？

问题描述

我要在我的项目中实施。

I want to implement ZipArchive in my project.

使用这个库我想将图像文件存档为zip文件。

Using this library I want to archive files like images into zip file.

我该如何做？

推荐答案

试用我的代码
Zipcode：

try my codeZipcode :

    NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* dPath = [paths objectAtIndex:0];
    NSString* txtfile = [dPath stringByAppendingPathComponent:@"test.txt"];
    NSString* zipfile = [dPath stringByAppendingPathComponent:@"test.zip"];
    ZipArchive* zip = [[ZipArchive alloc] init];
    BOOL ret = [zip CreateZipFile2:zipfile];
    ret = [zip addFileToZip:txtfile newname:@"test.txt"];//zip
    if( ![zip CloseZipFile2] )
    {
        zipfile = @"";
    }
    [zip release];
    NSLog(@"The file has been zipped");

解压缩：

    NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString* dPath = [paths objectAtIndex:0];

    NSString* zipfile = [dPath stringByAppendingPathComponent:@"test.zip"] ;
    NSString* unzipto = [dPath stringByAppendingPathComponent:@"test"] ;
    ZipArchive* zip = [[ZipArchive alloc] init];
    if([zip UnzipOpenFile:zipfile] )
    {
        BOOL ret = [zip UnzipFileTo:unzipto overWrite:YES];
        if(NO == ret)
        {
        }
        [zip UnzipCloseFile];
    }
    [zip release];
    NSLog(@"The file has been unzipped");
