Zip library issue - ios

Question

So I am using this library: https://github.com/flyingdolphinstudio/Objective-Zip
I implemented it and am trying to take a UIImage and NSString and make it a .png and .txt in the .zip file, respectively.
Now these are my 2 concerns, I am trying to save the *zipFile below to the documents directory.
Now with the dropbox API, how come I can't just provide the file itself and skip the path. It seems like I HAVE to save the .zip to the documents directory first and then get the path so I can then upload it to dropbox. Do I have to do that?
In the ...writeToFile line, I am getting a warning that ZipFile may not respond to writeToFile so how would I properly save it to the documents directory?
Anyway this is the code I have so far:
NSString *filename = [NSString stringWithFormat:#"%#.zip", textField.text];
ZipFile *zipFile= [[ZipFile alloc] initWithFileName:filename mode:ZipFileModeCreate];
//Image
NSString *nameImage = #"Image.png";
NSMutableDictionary *theDictionary = [Singleton sharedSingleton].dictionary;
NSData *data = [theDictionary objectForKey:#"image"];
ZipWriteStream *writeImage = [zipFile writeFileInZipWithName:nameImage compressionLevel:ZipCompressionLevelBest];
[writeImage writeData:data];
[writeImage finishedWriting];
//Text
NSString *nameText = #"Text.txt";
NSData *dataText = [textView.text dataUsingEncoding:NSUTF8StringEncoding];
ZipWriteStream *writeText = [zipFile writeFileInZipWithName:nameText compressionLevel:ZipCompressionLevelBest];
[writeText writeData:dataText];
[writeText finishedWriting];
//Now we HAVE to save it to the documents directory to get it to work with dropbox
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0]; //Get the docs directory
NSString *filePath = [documentsPath stringByAppendingPathComponent:filename]; //Add the file name
[zipFile writeToFile:filePath atomically:YES encoding:NSUTF8StringEncoding error:NULL];
//Save to Dropbox
NSString *zipPath = [[NSBundle mainBundle] pathForResource:textField.text ofType:#"zip"];
[[self restClient] uploadFile:filename toPath:#"/" withParentRev:nil fromPath:zipPath];
So what am I doing wrong here?
Thanks!

It looks to me like ZipFile already writes to a file, so there's no need for something like writeToFile. Just initialize zipFile with the path you want, be sure to close the file at the end ([zipFile close]), and then upload to Dropbox as you would any other file.
