一、SSZipArchive
1.簡介
SSZipArchive是iOS和Mac上一個簡單實用的壓縮和解壓插件。用途包括：
1.解壓zip文件；
2.解壓密碼保護的ZIP文件；
3.創建新的zip文件；
4.追加文件到現有的壓縮；
5.壓縮文件；
6.壓縮NSData（帶有文件名）
SSZipArchive的GitHub地址：https://github.com/ZipArchive/ZipArchive
2.壓縮方法
壓縮指定文件代碼：
1 /** 2 * SSZipArchive壓縮 3 */ 4 -(void)ssZipArchiveWithFiles 5 { 6 //Caches路徑 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //zip壓縮包保存路徑 9 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 10 //需要壓縮的文件 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 //創建不帶密碼zip壓縮包 18 BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withFilesAtPaths:filesPath]; 19 //創建帶密碼zip壓縮包 20 //BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withFilesAtPaths:filesPath withPassword:@"SSZipArchive.zip"]; 21 }
壓縮指定文件夾代碼：
1 /** 2 * SSZipArchive壓縮 3 */ 4 -(void)ssZipArchiveWithFolder 5 { 6 //Caches路徑 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //zip壓縮包保存路徑 9 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 10 //需要壓縮的文件夾路徑 11 NSString *folderPath = @"/Users/apple/Desktop/demo/"; 12 //創建不帶密碼zip壓縮包 13 BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withContentsOfDirectory:folderPath ]; 14 //創建帶密碼zip壓縮包 15 //BOOL isSuccess = [SSZipArchive createZipFileAtPath:path withContentsOfDirectory:folderPath withPassword:@"SSZipArchive.zip"]; 16 }
3.解壓方法
代碼：
1 /** 2 * SSZipArchive解壓 3 */ 4 -(void)uSSZipArchive 5 { 6 //Caches路徑 7 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 8 //解壓目標路徑 9 NSString *destinationPath =[cachesPath stringByAppendingPathComponent:@"SSZipArchive"]; 10 //zip壓縮包的路徑 11 NSString *path = [cachesPath stringByAppendingPathComponent:@"SSZipArchive.zip"]; 12 //解壓 13 BOOL isSuccess = [SSZipArchive unzipFileAtPath:path toDestination:destinationPath]; 14 }
二、ZipArchive
1.簡介
ZipArchive可以解壓和壓縮
2.壓縮方法
代碼：
1 /** 2 * ZipArchive壓縮 3 */ 4 -(void)zipArchiveWithFiles 5 { 6 //創建解壓縮對象 7 ZipArchive *zip = [[ZipArchive alloc]init]; 8 //Caches路徑 9 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 10 //zip壓縮包保存路徑 11 NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];//創建不帶密碼zip壓縮包
12 //創建zip壓縮包 13 [zip CreateZipFile2:path]; 14 //創建帶密碼zip壓縮包 15 //[zip CreateZipFile2:path Password:@"ZipArchive.zip"]; 16 //添加到zip壓縮包的文件 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 //關閉壓縮 22 BOOL success = [zip CloseZipFile2]; 23 }
3.解壓方法
代碼：
1 /** 2 * ZipArchive解壓 3 */ 4 -(void)uZipArchive 5 { 6 //創建解壓縮對象 7 ZipArchive *zip = [[ZipArchive alloc]init]; 8 //Caches路徑 9 NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject]; 10 //解壓目標路徑 11 NSString *savePath =[cachesPath stringByAppendingPathComponent:@"ZipArchive"]; 12 //zip壓縮包的路徑 13 NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"]; 14 //解壓不帶密碼壓縮包 15 [zip UnzipOpenFile:path]; 16 //解壓帶密碼壓縮包 17 //[zip UnzipOpenFile:path Password:@"ZipArchive.zip"]; 18 //解壓 19 [zip UnzipFileTo:savePath overWrite:YES]; 20 //關閉解壓 21 BOOL success = [zip UnzipCloseFile]; 22 }
