Question

我让我的应用创建一个文件，将其压缩成.zip文件，然后将其附加到电子邮件中。但是.zip文件在实际文件之前包含许多目录。从'/'开始，它是一个无名文件夹，看起来对接收它的人来说是不可见的。顶级目录是'/'，下一级是'com'...
/var/mobile/Applications/CDA16BB231BDABABBA/Documents/data.txt

如何删除所有目录并让.zip文件只包含文件？

这是我用过的代码......

    NSError *error;
    NSString *documentsDirectory = [NSHomeDirectory()
                                    stringByAppendingPathComponent:@"Documents"];
    NSString *filePath = [documentsDirectory
                          stringByAppendingPathComponent:@"data.txt"];
    NSLog(@"string to write:%@",printString);
    [printString writeToFile:filePath atomically:YES
                    encoding:NSUTF8StringEncoding error:&error];

    ////ZIP FILE/////

    NSString *zipfilePath = [documentsDirectory stringByAppendingPathComponent:@"data.zip"];
    [[NSFileManager defaultManager] removeItemAtPath: zipfilePath error: &error];

    ZipFile *zipFile = [[ZipFile alloc]initWithFileName:zipfilePath mode:ZipFileModeCreate];

    NSDictionary *attributes = [[NSFileManager defaultManager]attributesOfItemAtPath:zipfilePath error:&error];
    NSDate *Date = [attributes objectForKey:NSFileCreationDate];

    ZipWriteStream *stream = [zipFile writeFileInZipWithName:filePath fileDate:Date compressionLevel:ZipCompressionLevelBest];
    NSData *data = [NSData dataWithContentsOfFile:filePath];
    [stream writeData:data];
    [stream finishedWriting];


    [zipFile close];

问题是你在说：

writeFileInZipWithName:filePath

变量filePath包含您抱怨的巨大长名称。它是从顶部一直到实际文件的整个路径。

您的文件名是@"data.txt"，所以您要说的是：

writeFileInZipWithName:@"data.txt"
