I am using multipeer connectivity in my application. The user can send any file, such as a png or a recording to another peer. Since the transfer was slow I thought that zipping the data in a zip would speed it up as the size is reduced. I decided to use a framework for this suggested in the second answer to this question:
How can I create a zip file by using Objective C?
The problem is that I need to provide the usl of the file to send it via bluetooth, and I tried doing it in this way:
NSData *file = [NSData dataWithContentsOfURL:imageUrl];
ZipFile *zipFile= [[ZipFile alloc] initWithFileName:@"file.zip" mode:ZipFileModeCreate];
ZipWriteStream *stream= [zipFile writeFileInZipWithName:@"abc.txt" compressionLevel:ZipCompressionLevelBest];
[stream writeData:file];
[stream finishedWriting];
NSString *docsDir;
NSArray *dirPaths;
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
NSString *databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent:@"file.zip"]];
[stream writeToFile:databasePath atomically:YES];
_progressSend = [session sendResourceAtURL: WHAT URL?? withName: info toPeer:peerID withCompletionHandler:^(NSError *error) {
// Implement this block to know when the sending resource transfer completes and if there is an error.
if (error) {
NSLog(@"Send resource to peer [%@] completed with Error [%@]", peerID.displayName, error);
}
else {
// Create an image transcript for this received image resource
}
}];
The problem is that I don't get how to get the url of the zip. I can't even save it in the documents directory...
