我有一个使用 ARC 开发的 iPhone 应用程序。我的文档目录中有一个文件夹,其中包含一堆图像,我需要将其压缩并通过电子邮件发送。我的项目使用 ARC。

有没有人有任何示例代码/链接到对我有帮助的资源?

我一直在网上搜索,我发现的内容与 ARC 不兼容——即使它声称是。

从该链接http://code.google.com/p/objective-zip/downloads/list (Objective-zip)下载 Objective-Zip、MiniZip 和 ZLib 并将其拖放到您的项目中。导入文件:ZipFile.h、ZipException.h、FileInZipInfo.h、ZipWriteStream.h、ZipReadStream.h、zlib.h

使用此代码。请看下面:

NSString *stringPath1 = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]];
    NSString *FileName=[stringPath1 stringByAppendingPathComponent:@"Your file name"];


    NSString *stringPath=[stringPath1 stringByAppendingPathComponent:[@"Your file name" stringByAppendingFormat:@".zip"]];
    NSArray *files = [[NSFileManager defaultManager]contentsOfDirectoryAtPath:FileName error:&error];
    ZipFile *zipFile = [[ZipFile alloc]initWithFileName:stringPath mode:ZipFileModeCreate];

    for(int i = 0;i<files.count;i++){

        id myArrayElement = [files  objectAtIndex:i];
        NSLog(@"add %@", myArrayElement);

        NSString *path = [FileName stringByAppendingPathComponent:myArrayElement];
        NSDictionary *attributes = [[NSFileManager defaultManager]attributesOfItemAtPath:path error:&error];
        NSDate *Date = [attributes objectForKey:NSFileCreationDate];

        ZipWriteStream *streem = [zipFile writeFileInZipWithName:myArrayElement fileDate:Date compressionLevel:ZipCompressionLevelBest];
        NSData *data = [NSData dataWithContentsOfFile:path];
        [streem writeData:data];
        [streem finishedWriting];
    }

    [zipFile close];
