使用第三方框架ZipArchive进行压缩与解压，cocoapod：pod 'ZipArchive'
1.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* 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 = @"";
}
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];
}
乱码处理问题
里面是一些带特殊符号的文件， 使用zipArchive解压后会出现乱码。
解决方法是到ZipArchive.mm文件中找到
NSString * strPath = [NSString
stringWithCString:filename];
换成UTF8方式解压, 如下：
NSString * strPath = [NSString
stringWithUTF8String:filename];
但是有时后中文也会有问题， 用如下方式：
NSStringEncoding enc =
CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);
NSString * strPath = [NSString
stringWithCString:filename encoding:enc];
