You can try this method, I have tested it and is working The PHP <pre><code><?php $image = $_REQUEST['image']; $imageFileName = "miImage.jpg"; $binary = base64_decode($image); $file = fopen($imageFileName, 'wb'); fwrite($file, $binary); fclose($file); echo "Upload completed with success"; ?> </code></pre> In YourViewController.h file <pre><code>@interface YourViewController : UIViewController { NSURLConnection *serverConnection; NSMutableData *returnData; } </code></pre> Copy and paste this method in YourViewController.m file <pre><code>- (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]; } </code></pre> Now this are the lines of code to send the image <pre><code>NSURL *sendURL = [NSURL URLWithString:@"http://yourdomain.com/yourphp.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"]; stringBody = [[NSString alloc] initWithFormat:@"image=%@", encodedString]; [sendRequest setHTTPBody:[stringBody dataUsingEncoding:NSUTF8StringEncoding]]; serverConnection = [[NSURLConnection alloc] initWithRequest:sendRequest delegate:self]; [serverConnection start]; </code></pre> Last thing is to set the delegate methods of the server connection <pre><code>- (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 { NSString *responseString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"Response: %@", responseString); if ([responseString isEqualToString:@"Upload completed with success"]) { /* Do something on success */ } else { /* Do something if not succeeded */ } } - (void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { /* Do something in fail */ } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
