I'm trying to make a sort of camera application. If the user takes a photo, he has te possibility to upload this photo to a FTP server.
Now i've read and tried a lot but it still doesn't works.
This is the code I have at the moment, it's being executed when the user clicks the "Upload picture" button. I got this code from the iPhone developer reference created by Apple so it should work..?
Code:
- (IBAction)emailPicture {
NSString *pictureLocation = [NSHomeDirectory() stringByAppendingString:@"/Documents/Pictures/"];
pictureLocation = [pictureLocation stringByAppendingString:[NSString stringWithFormat:@"%lu", currentPictureViewing]];
pictureLocation = [pictureLocation stringByAppendingString:@".jpg"];
/*
UIImage *selectedImage = [UIImage imageWithContentsOfFile:pictureLocation];
NSData *imageData = UIImageJPEGRepresentation(selectedImage, 100);
*/
NSString *ftpServer = @"domain.com";
NSString *ftpUsername = @"user";
NSString *ftpPassword = @"pass";
CFWriteStreamRef writeStream;
CFReadStreamRef readStream;
CFStreamClientContext context = { 0, NULL, NULL, NULL, NULL };
CFURLRef uploadURL, destinationURL;
CFStringRef fileName;
Boolean success = true;
MyStreamInfo *streamInfo;
/* Create a CFURL from the upload directory string */
destinationURL = CFURLCreateWithString(kCFAllocatorDefault, (CFStringRef)ftpServer, NULL);
/* Copy the end of the file path and use it as the file name. */
CFURLRef tmpFileName = (CFURLRef)pictureLocation;
fileName = CFURLCopyLastPathComponent(tmpFileName);
assert(fileName != NULL);
/* Create the destination URL by taking the upload directory and appending the file name. */
uploadURL = CFURLCreateCopyAppendingPathComponent(kCFAllocatorDefault, destinationURL, fileName, false);
assert(uploadURL != NULL);
CFRelease(destinationURL);
CFRelease(fileName);
/* Create a CFReadStream from the local file being uploaded. */
readStream = CFReadStreamCreateWithFile(kCFAllocatorDefault,(CFURLRef)pictureLocation);
assert(readStream != NULL);
/* Create an FTP write stream for uploading operation to a FTP URL. If the URL specifies a
directory, the open will be followed by a close event/state and the directory will have been
created. Intermediary directory structure is not created. */
writeStream = CFWriteStreamCreateWithFTPURL(kCFAllocatorDefault, uploadURL);
assert(writeStream != NULL);
CFRelease(uploadURL);
/* Initialize our MyStreamInfo structure, which we use to store some information about the stream. */
MyStreamInfoCreate(&streamInfo, readStream, writeStream);
context.info = (void *)streamInfo;
/* CFReadStreamOpen will return success/failure. Opening a stream causes it to reserve all the
system resources it requires. If the stream can open non-blocking, this will always return TRUE;
listen to the run loop source to find out when the open completes and whether it was successful. */
success = CFReadStreamOpen(readStream);
if (success) {
/* CFWriteStreamSetClient registers a callback to hear about interesting events that occur on a stream. */
//success = CFWriteStreamSetClient(writeStream, kNetworkEvents, MyUploadCallBack, &context);
success = TRUE;
if (success) {
/* Schedule a run loop on which the client can be notified about stream events. The client
callback will be triggered via the run loop. It's the caller's responsibility to ensure that
the run loop is running. */
CFWriteStreamScheduleWithRunLoop(writeStream, CFRunLoopGetCurrent(), kCFRunLoopCommonModes);
MyCFStreamSetUsernamePassword(writeStream, (CFStringRef)ftpUsername, (CFStringRef)ftpPassword);
MyCFStreamSetFTPProxy(writeStream, &streamInfo->proxyDict);
/* CFWriteStreamOpen will return success/failure. Opening a stream causes it to reserve all the
system resources it requires. If the stream can open non-blocking, this will always return TRUE;
listen to the run loop source to find out when the open completes and whether it was successful. */
success = CFWriteStreamOpen(writeStream);
if (success == false) {
fprintf(stderr, "CFWriteStreamOpen failedn");
MyStreamInfoDestroy(streamInfo);
}
} else {
fprintf(stderr, "CFWriteStreamSetClient failedn");
MyStreamInfoDestroy(streamInfo);
}
} else {
fprintf(stderr, "CFReadStreamOpen failedn");
MyStreamInfoDestroy(streamInfo);
}
}
In the headerfile I also have the following code:
Code:
#define kMyBufferSize 32768
/* MyStreamInfo holds the state of a particular operation (download, upload, or
directory listing. Some fields are only valid for some operations, as explained
by their comments. */
typedef struct MyStreamInfo {
CFWriteStreamRef writeStream; // download (destination file stream) and upload (FTP stream) only
CFReadStreamRef readStream; // download (FTP stream), upload (source file stream), directory list (FTP stream)
CFDictionaryRef proxyDict; // necessary to workaround <rdar://problem/3745574>, per discussion below
SInt64 fileSize; // download only, 0 indicates unknown
UInt32 totalBytesWritten; // download and upload only
UInt32 leftOverByteCount; // upload and directory list only, number of valid bytes at start of buffer
UInt8 buffer[kMyBufferSize]; // buffer to hold left over bytes
} MyStreamInfo;
When I compile, some weird errors comes:
Code:
"_MyCFStreamSetFTPProxy" referenced from:
-[appTabBarController emailPicture] in appTabBarController.o
"_MyStreamInfoCreate", referenced from:
-[appTabBarController, emailPicture] in appTabBarController.o
etc..
etc..
I can't click on those errors but I think they have something to do with some warnings I get:
Code:
warning: implicit declaration of function 'MyCFStreamSetFTPProxy'
warning: implicit declaration of function 'MyStreamInfoCreate'
etc...
etc...
I'm developing with Xcode and included the CFNetwork framework into my project. Also imported CFNetwork.h into my headerfile but that also doesn't fix the warnings/errors...
Can you please help me?
