I have NSString which is unicode encoded. For example عنم١٢ which is internally represented like "\U0639\U0646\U0645\U0661\U0662\U0663".
I am sending this string to a remote server which is basically a LAMP server. Please note that I do not have any access to that server.
The server seems to have problem with \U, but works fine for \u.
I tried the following piece of code which did not work for me:
NSString *resourceparams = [NSString stringWithFormat:#"%#",sender,nil];
NSLog(#"before replace resourceparams: %#", resourceparams);
resourceparams = [resourceparams stringByReplacingOccurrencesOfString:#"\\U" withString:#"\\u"];
NSLog(#"after replace resourceparams: %#", resourceparams);
Any suggestions ?
Edit: (Adding how this data is sent in the body of a Post request)
NSMutableData *postBody = [NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
NSEnumerator * enumerator = [[paramDict allKeys] objectEnumerator];
NSString * dataKey = nil;
while (( dataKey = [enumerator nextObject]) ) {
id dataVal = [paramDict objectForKey: dataKey];
[postBody appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n", boundry] dataUsingEncoding:NSUTF8StringEncoding]];
if([dataVal isKindOfClass: [NSData class]]) {
NSString* contentDisposition = [NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"file.ext\"\r\n", dataKey];
[postBody appendData: [contentDisposition dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:dataVal];
} else {
[postBody appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", dataKey] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[dataVal dataUsingEncoding:NSUTF8StringEncoding]];
}
You could try a lowercase stringobject. Where your function will look like:
NSString *resourceparams = [[NSString stringWithFormat:#"%#",sender,nil] lowerCaseString];
This will non-capitalize each nsstring object.

I am new to iPhone programming. Can any body tell me I have upload image and audio along with these parameters
Input Parameters: caption, user_id, mobile_tauky_id, blauky_id, image, audio (caption and blauky_id are optional)
Using below code i can upload image, similarly I want to upload first caption, user_id means some integer value ex: 3, mobile_tauky_id also some integer value ex: 5, blauky_id also ex: 2, image and audio.
Where can I append these parameters First I want append Caption, next user_id, then mobile_tauky_id, blauky_id, after that i have to append image and audio. Can any body tell me how can I append these parameters in below code. I can only able to append image but before that i want to appendcaption, user_id, mobile_tauky_id.
NSString *urlString = #"http://182.73.152.59:82/php/tauky_services/codeigniter-restserver-master/index.php/api/uploadClass/uploadTauky/";

First, there are different styles of web services, and you haven't specified which you're dealing with. Is it a SOAP-based service? REST? XML-RPC? For the sake of discussion, I'll assume it's a RESTful service, since that's where most people seem to be going these days.
The problem I see is that you're trying to put the parameters in the body of the post. You'll have to check the documentation for the specific API that you're using, but usually parameters are provided either as query parameters in the URL that you're posting to, or specified in the headers that you send in the request. The body of the request should be the zipped data.
Try to Send the file your file in this way

[data getBytes:byteData length:length];

` I am trying to uplaod video file to the specified url of twit pic which helps the user to upload their videos to twitter. When i press button video file should upload into the url which i used. but when i check,getting a response that the page you requested could not be found.Has anyone tried to upload videos to twit pic. Please give me some sample codes.Thanks in advance.
the error is related to the incorrect urlString. I also dont see which twitpic-api-version you are using.
twitpic-api-version-2 (latest api-version this should be used) needs authorization first via OAuth and api-key, message and media as parameters
urlString should look like: http://api.twitpic.com/2/upload.xml
twitpic-api-version-1 (not the latest one: only there because of compability. Will be shut down sometime in future) needs the parameters you added but also two additional oauth-parameter which are missing in your body.
urlString should look like: http://api.twitpic.com/1/upload.xml
I've successfully created two different methods where each of them can upload either an image or text. But I am having problem writing a method that can post both text and image simultaneously!
// Here's my new method witch worked fine thanx to #sgosha:
- (void) upload {

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];

[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// Text parameter1
NSString *param1 = #"parameter text";
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"parameter1\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

//Old question:
Obviously this was too easy and didn't work! I do not get any error in the console or anything, and the image is uploaded, but the text is not sent. Any ideas?
Btw: The server-side script is a very simple php script.
Try this (EDITED):
NSMutableData *body = [NSMutableData data];
// file
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Disposition: attachment; name=\"userfile\"; filename=\".jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// text parameter
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"parameter1\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[parameterValue1 dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// another text parameter
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"parameter2\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[parameterValue2 dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// set request body
[request setHTTPBody:body];
I also wanted to upload an image along with other data in the same POST, most information about uploading images is just for uploading an image alone in one server connection, here is how I solved this.
This is the PHP
<?php
/* As you can see there are more values not only the image */
$variableOne = $_POST['variableOne'];
$variableTwo = $_POST['variableTwo'];
$variableThree = $_POST['variableThree'];
$variableFour = $_POST['variableFour'];
$variableFive = $_POST['variableFive'];
$variableSix = $_POST['variableSix'];
$variableSeven = $_POST['variableSeven'];
$variableEight = $_POST['variableEight'];
$variableNine = $_POST['variableNine'];
$variableTen = $_POST['variableTen'];
/* Our image */
$image = $_REQUEST['image'];
/* This is for trying to get a unique name for the image file, since maybe you want to store large amount of images */
$currentDate = date("Y-m-d");
$name = "" . $currentDate . microtime() . rand(0, 999) . rand(0, 999) . rand(0, 999) . ".jpg";
/*
* Here comes the image stuff
*/
if (file_exists($name)) {
echo "File already exists";
} else {
/* Decoding image */
$binary = base64_decode($image);
/* Opening image */
$file = fopen($name, 'wb');
/* Writing to server */
fwrite($file, $binary);
/* Closing image file */
fclose($file);
echo "Added";
}
}
?>
Then in Xcode copy and paste this method (taken from Creating a base-64 string from NSData)
- (NSString*)base64forData:(NSData*) theData {
const uint8_t* input = (const uint8_t*)[theData bytes];
NSInteger length = [theData length];
static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
NSMutableData* data = [NSMutableData dataWithLength:((length + 2) / 3) * 4];
uint8_t* output = (uint8_t*)data.mutableBytes;
NSInteger i;
for (i=0; i < length; i += 3) {
NSInteger value = 0;
NSInteger j;
for (j = i; j < (i + 3); j++) {
value <<= 8;
if (j < length) {
value |= (0xFF & input[j]);
}
}
NSInteger theIndex = (i / 3) * 4;
output[theIndex + 0] = table[(value >> 18) & 0x3F];
output[theIndex + 1] = table[(value >> 12) & 0x3F];
output[theIndex + 2] = (i + 1) < length ? table[(value >> 6) & 0x3F] : '=';
output[theIndex + 3] = (i + 2) < length ? table[(value >> 0) & 0x3F] : '=';
}
return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
}
In YourViewController.h file
#interface YourViewController : UIViewController {
NSURLConnection *serverConnection;
NSMutableData *returnData;
}
This is the server connection code
NSURL *sendURL = [NSURL URLWithString:#"http://yourdomainname/imagefolder/phpscript.php"];
NSMutableURLRequest *sendRequest = [NSMutableURLRequest requestWithURL:sendURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30];
[sendRequest setHTTPMethod:#"POST"];
[sendRequest setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
NSData *imageData = UIImageJPEGRepresentation(yourImage, 1.0);
NSString *encodedString = [[self base64forData:imageData] stringByReplacingOccurrencesOfString:#"+" withString:#"%2B"];
NSString *dataToSend = [[NSString alloc] initWithFormat:#"variableOne=%#&variableTwo=%#&variableThree=%#&variableFour=%#&variableFive=%#&variableSix=%#&variableSeven=%#&variableEight=%#&variableNine=%#&variableTen=%#&image=%#", valueOne, valueTwo, valueThree, valueFour, valueFive, valueSix, valueSeven, valueEight, valueNine, valueTen, encodedString];
[sendRequest setHTTPBody:[dataToSend dataUsingEncoding:NSUTF8StringEncoding]];
serverConnection = [[NSURLConnection alloc] initWithRequest:sendRequest delegate:self];
[serverConnection start];
Set delegate methods for server connection
- (void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
returnData = [[NSMutableData alloc] init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[returnData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if (connection == serverConnection) {
NSString *responseString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"Response: %#", responseString);
if ([responseString isEqualToString:#"Added"]) {
/* Make something on success */
} else {
/* Make something else if not completed with success */
}
}
}
- (void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
/* Make something on failure */
}
This code works for me with 1 image and 7 other parameters using POST Request
Make sure to change your variable names plus values and also image parameter name plus 'showPhoto' which is my IBOutlet UIImageView object
'name' shows URL parameter name.
