Question

我正在将所有NSLOG写入文本文件，并在点击表格视图单元格后将其发布到服务器。我在使用NSURLConnection发布之前将文本文件转换为zip文件。但是，Zip文件中存在一些垃圾数据，但文本文件具有正确的内容。我正在使用SSZipArchive，我用来发布文件的代码是

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *logFilePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"Logger.txt"]];

NSString* zipfile = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"Logger.zip"]];
//create zip file, return true on success

BOOL isZipCreated=[SSZipArchive createZipFileAtPath:zipfile withContentsOfDirectory:logFilePath];

if (isZipCreated) {

    NSLog(@"Zip file Created at Path : %@",zipfile);
     NSString *contentOfZipFile = [NSString stringWithContentsOfFile:zipfile encoding:NSUTF8StringEncoding error:NULL];
    NSData *zipData = [contentOfZipFile dataUsingEncoding:NSUTF8StringEncoding];


    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[zipData length]];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:finalURL]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/zip" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:zipData ];


    NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
}

else {
     NSLog(@"Zip create error");
}

任何帮助都会有很大的帮助。

你可以使用这个库Objective-Zip，实际上我已经使用了它，它对我来说很好。

创建Zip文件：

ZipFile *zipFile= [[ZipFile alloc] initWithFileName:@"Logger.zip" mode:ZipFileModeCreate];

将文件添加到zip文件

ZipWriteStream *stream= [zipFile writeFileInZipWithName:@"Logger.txt" compressionLevel:ZipCompressionLevelBest];

[stream writeData：abcData]; [stream finishedWriting];

从zip文件中读取文件：

ZipFile *unzipFile= [[ZipFile alloc] initWithFileName:@"Logger.zip" mode:ZipFileModeUnzip];

[unzipFile goToFirstFileInZip];

ZipReadStream *read= [unzipFile readCurrentFileInZip];
NSMutableData *data= [[NSMutableData alloc] initWithLength:256];
int bytesRead= [read readDataWithBuffer:data];

[read finishedReading];

希望这段代码可以帮到你:) 快乐编码!! ;）

Zip文件未在iOS中正确创建
