一、SSZipArchive
1.简介
SSZipArchive是iOS和Mac上一个简单实用的压缩和解压插件。用途包括：
1.解压zip文件；
2.解压密码保护的ZIP文件；
3.创建新的zip文件；
4.追加文件到现有的压缩；
5.压缩文件；
6.压缩NSData（带有文件名）
SSZipArchive的GitHub地址：https://github.com/ZipArchive/ZipArchive
2.压缩方法
压缩指定文件代码：
1 /** 2 * SSZipArchive压缩 3 */ 4 -(void)ssZipArchiveWithFiles 5 { 6 //Caches路径 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //zip压缩包保存路径 9 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 10 //需要压缩的文件 11 NSArray *filesPath = @[ 12 @"/Users/apple/Desktop/demo/LaunchImage-2-700-568h@2x.png", 13 @"/Users/apple/Desktop/demo/LaunchImage-2-700@2x.png", 14 @"/Users/apple/Desktop/demo/LaunchImage-2-800-667h@2x.png", 15 @"/Users/apple/Desktop/demo/LaunchImage-2-800-Landscape-736h@3x.png" 16 ]; 17 //创建不带密码zip压缩包 18 BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withFilesAtPaths:filesPath]; 19 //创建带密码zip压缩包 20 //BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withFilesAtPaths:filesPath withPassword:@"SSZipArchive.zip"]; 21 }
压缩指定文件夹代码：
1 /** 2 * SSZipArchive压缩 3 */ 4 -(void)ssZipArchiveWithFolder 5 { 6 //Caches路径 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //zip压缩包保存路径 9 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 10 //需要压缩的文件夹路径 11 NSString *folderPath = @"/Users/apple/Desktop/demo/"; 12 //创建不带密码zip压缩包 13 BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withContentsOfDirectory:folderPath ]; 14 //创建带密码zip压缩包 15 //BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withContentsOfDirectory:folderPath withPassword:@"SSZipArchive.zip"]; 16 }
3.解压方法
代码：
1 /** 2 * SSZipArchive解压 3 */ 4 -(void)uSSZipArchive 5 { 6 //Caches路径 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //解压目标路径 9 NSString *destinationPath =[cachesPath stringByAppendingPathComponent:@"SSZipArchive"]; 10 //zip压缩包的路径 11 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 12 //解压 13 BOOL isSuccess = [SSZipArchive unzipFileAtPath:path toDestination:destinationPath]; 14 }
二、ZipArchive
1.简介
ZipArchive可以解压和压缩
2.压缩方法
代码：
1 /** 2 * ZipArchive压缩 3 */ 4 -(void)zipArchiveWithFiles 5 { 6 //创建解压缩对象 7 ZipArchive *zip = [[ZipArchive alloc]init]; 8 //Caches路径 9 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 10 //zip压缩包保存路径 11 NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];//创建不带密码zip压缩包
12 //创建zip压缩包 13 [zip CreateZipFile2:path]; 14 //创建带密码zip压缩包 15 //[zip CreateZipFile2:path Password:@"ZipArchive.zip"]; 16 //添加到zip压缩包的文件 17 [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-700-568h@2x.png" newname:@"1.png"]; 18 [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-700@2x.png" newname:@"2.png"]; 19 [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-800-667h@2x.png" newname:@"3.png"]; 20 [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-800-Landscape-736h@3x.png" newname:@"4.png"]; 21 //关闭压缩 22 BOOL success = [zip CloseZipFile2]; 23 }
3.解压方法
代码：
1 /** 2 * ZipArchive解压 3 */ 4 -(void)uZipArchive 5 { 6 //创建解压缩对象 7 ZipArchive *zip = [[ZipArchive alloc]init]; 8 //Caches路径 9 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 10 //解压目标路径 11 NSString *savePath =[cachesPath stringByAppendingPathComponent:@"ZipArchive"]; 12 //zip压缩包的路径 13 NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"]; 14 //解压不带密码压缩包 15 [zip UnzipOpenFile:path]; 16 //解压带密码压缩包 17 //[zip UnzipOpenFile:path Password:@"ZipArchive.zip"]; 18 //解压 19 [zip UnzipFileTo:savePath overWrite:YES]; 20 //关闭解压 21 BOOL success = [zip UnzipCloseFile]; 22 }
