I have been using SampleFTP from Apple but I cannot understand the procedure, I mean, in other languages is simple as set the URL, Path, user and password then "navigate" and download or upload things to that Path... but I don't understand how to do in iOS... I don't have any NSFtp or whatever...
EDIT:
From the begining my #import "NetworkManager.h" does not work, error.
Can Use https://github.com/erica/iphone-3.0-cookbook-/tree/master/C13-Networking/15-FTP%20Helper
and
- (void) download
{
NSData *ftpData = [NSData dataWithContentsOfFile:[FTPHelper sharedInstance].filePath];
}
There is also the Karelia ConnectionKit. Free. Open Source and under active development.
There is no FTP inbuilt library for iOS,but you can find custom librariews for that like tihis one http://code.google.com/p/ios-ftp-server/ or http://www.chilkatsoft.com/ftp-objc.asp

I would like to download multiple offline map databases using MBXMapKit. This is more a Objective-C problem than a MBXMapKit library problem.
I would like to do something like this:
for ( DestinationObject *dest in self.dest ) {
//Put the map to the right position
[self centerMapWithDest:dest];
[[MBXOfflineMapDownloader sharedOfflineMapDownloader] beginDownloadingMapID:_rasterOverlay.mapID mapRegion:_mapView.region minimumZ:_rasterOverlay.minimumZ maximumZ:MIN(16,_rasterOverlay.maximumZ)];
}
and here the delegate function:
-(void)offlineMapDownloader:(MBXOfflineMapDownloader *)offlineMapDownloader didCompleteOfflineMapDatabase:
I know this is not possible like this because the library crashes after the second call because the first part is not finished yet.
But how to call the next download when the first one is finished ?
Thanks in advance
Per the documentation, you want to use the MBXOfflineMapDownloaderDelegate protocol to know when a download completes/fails out before starting the next one, since the downloaded class can only handle one download at a time.
I am currently making an app which converts an NSDictionary into a JSON file, in the intention of uploading it to a server. My issue is, is that I have no idea (let alone control) over what the name of the uploaded file is, how do I change/modify it?

This is something that should be handled by whatever FTP client library you are using.
For instance, FTPManager on GitHub (https://github.com/nkreipke/FTPManager) has the following method:
- (BOOL) uploadData:(NSData*)data withFileName:(NSString *)fileName toServer:(FMServer*)server;
That looks like it will fit your need just fine.
I'm trying to save the security scoped URL returned from iCloud document picker (UIDocumentPickerViewController)
The documentation states:
If the URL is not a ubiquitous URL, save a bookmark to the file using
the
bookmarkDataWithOptions:includingResourceValuesForKeys:relativeToURL:error:
method and passing in the NSURLBookmarkCreationWithSecurityScope
option. Calling this method creates a bookmark containing a
security-scoped URL that you can use to open the file without further
user intervention.
However, the compiler says that NSURLBookmarkCreationWithSecurityScope is not supported on iOS.
Anyone know what's going on here....?
After further digging, it turns out option NSURLBookmarkCreationWithSecurityScope is NOT needed at all when creating bookmark data in IOS. It's an option for OS X. You can just pass nil for the option field. I think Apple's document is confusing at the best.
However, you do need to call startAccessingSecurityScopedResource before creating the bookmark and make sure the call returns 1 (success) before proceed. Otherwise, bookmark creation will fail. Here is the sample code:
if ([url startAccessingSecurityScopedResource]==1) {
NSError *error;
NSData *bookmark = [url bookmarkDataWithOptions:nil
includingResourceValuesForKeys:nil
relativeToURL:nil
error:&error];
if (error) {
//handle error condition
} else {
// save your bookmark
}
}
[url stopAccessingSecurityScopedResource];
Again Apple's document is confusion at the best! It took me a lot of time to find out this. Hope this helps.
I ran into the same issue today, and indeed the compiler says NSURLBookmarkCreationWithSecurityScope is not available on iOS.
But to my surprise, if I use the raw constant instead (NSURLBookmarkCreationWithSecurityScope maps to ( 1 << 11 ), the method seems to work. It returns a valid bookmark data object, and when I call [[NSURL URLByResolvingBookmarkData:options:relativeToURL:bookmarkDataIsStale:stale], a valid security-scoped NSURL is returned and I can access the files and directories. Also, I tested these with iCloud Drive. And the documentation only says this should work for third-party document providers.
I am not sure how reliable this approach is, because it seems that Apple engineers didn't have time to finish up this feature, so disabled it in the last minute. Or it could be simply a bug in the header file. If anyone finds out more about this, please comment.
I'm new to IOS Development. This is the first time i'm hearing about FTP in IOS .I'm not getting, How to proceed further . I got this code https://developer.apple.com/library/ios/samplecode/SimpleFTPSample/Introduction/Intro.html .
But i didn't understand from this code .
I need to list the pdf files and folders from FTP . First i don't know how to establish the connection to FTP . Can any one please help me with steps.
I fyou look in ListController.m, listOrCancelAction is called when you click on List button.
In turn if you put a break point in startReceive you would see that
CFReadStreamCreateWithFTPURL is opening a "Open a CFFTPStream for the URL" with a specified URL.
I suggest you put a couple more break points and step through the code?
NSStreamDelegate is being used as callbacks when something is happening in particular
- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode
is called when connection is open or data is received.
Hope this is enough to get you started.
entryToAdd = [self entryByReencodingNameInEntry:(__bridge NSDictionary *) thisEntry encoding:NSUTF8StringEncoding];
in parseListData will have file name in kCFFTPResourceName which of course you can parse to find out if it is a PDF file. You may look at kCFFTPResourceType to see if you can use to determine file type, not sure.
I want to make the following webpage using CocoaHTTPServer: there should be a link to download a file, but the source file must be NSData object in memory.
As far as I see in samples, there is an easy way to link some file on iPhone to the hyperlink. Is it possible to "link" NSData?
Would be very thankful for examples.
All you need to do is to return HTTPDataResponse in your HTTPConnection subclass.
If you want an example have a look at the CocoaHTTPServer sample called DynamicServer and replace - httpResponseForMethod: URI: in MyHTTPConnection with something similar to the following:
- (NSObject<HTTPResponse> *)httpResponseForMethod:(NSString *)method URI:(NSString *)path
{
// Before returning you can analyze the passed path argument and select the correct data object to return...
return [[HTTPDataResponse alloc] initWithData:placeYourDataInstanceHere];
}
