ios - 如何在iOS的zip文件中添加多个文档？

我想制作一个包含多个文档的zip文件，这些文档取自我的文档目录。

BOOL isDir=NO;

NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSArray *subpaths;
for(int i=0; i<[arrdocument count]; i++)
{
    NSString *toCompress = [arrdocument objectAtIndex:i];
    NSString *pathToCompress = [documentsDirectory stringByAppendingPathComponent:toCompress];

    NSFileManager *fileManager = [NSFileManager defaultManager];

    if ([fileManager fileExistsAtPath:pathToCompress isDirectory:&isDir] && isDir){
        subpaths = [fileManager subpathsAtPath:pathToCompress];
    } else if ([fileManager fileExistsAtPath:pathToCompress]) {
        subpaths = [NSArray arrayWithObject:pathToCompress];
    }

    NSString *zipFilePath = [documentsDirectory stringByAppendingPathComponent:@"myZipFileName2.zip"];

    ZipArchive *za = [[ZipArchive alloc] init];
    [za CreateZipFile2:zipFilePath];

    if (isDir) {
        for(NSString *path in subpaths){
            NSString *fullPath = [pathToCompress stringByAppendingPathComponent:path];
            if([fileManager fileExistsAtPath:fullPath isDirectory:&isDir] && !isDir){
                [za addFileToZip:fullPath newname:path];
            }
        }
    } else {
        [za addFileToZip:pathToCompress newname:toCompress];
    }
}

但是，当我查看zip文件时，它在zip文件中仅显示一个文档吗？

最佳答案

似乎您在每次循环迭代中都重新创建了zip文件。您应该改为将zip文件的创建移出循环，或仅在创建zip文件时指定附加，如下所示:

[za CreateZipFile2:zipFilePath append:YES];
