как загрузить файл изображения из каталога документов на php-сервер в iphone

 NSData *imageData = UIImagePNGRepresentation([UIImage imageWithContentsOfFile:pathToStoreImage]); NSString *str = [self base64StringFromData:imageData length:0]; 

И тогда вы можете передать объект str любому параметру сервера.

используйте функцию base64StringFromData в вашем .m файле;

 -(NSString *) base64StringFromData: (NSData *)data length: (int)length { unsigned long ixtext, lentext; long ctremaining; unsigned char input[3], output[4]; short i, charsonline = 0, ctcopy; const unsigned char *raw; NSMutableString *result; lentext = [data length]; if (lentext < 1) return @""; result = [NSMutableString stringWithCapacity: lentext]; raw = [data bytes]; ixtext = 0; while (true) { ctremaining = lentext - ixtext; if (ctremaining <= 0) break; for (i = 0; i < 3; i++) { unsigned long ix = ixtext + i; if (ix < lentext) input[i] = raw[ix]; else input[i] = 0; } output[0] = (input[0] & 0xFC) >> 2; output[1] = ((input[0] & 0x03) << 4) | ((input[1] & 0xF0) >> 4); output[2] = ((input[1] & 0x0F) << 2) | ((input[2] & 0xC0) >> 6); output[3] = input[2] & 0x3F; ctcopy = 4; switch (ctremaining) { case 1: ctcopy = 2; break; case 2: ctcopy = 3; break; } for (i = 0; i < ctcopy; i++) [result appendString: [NSString stringWithFormat: @"%c", base64EncodingTable[output[i]]]]; for (i = ctcopy; i < 4; i++) [result appendString: @"="]; ixtext += 3; charsonline += 4; if ((length > 0) && (charsonline >= length)) charsonline = 0; } return result; } 

Вы можете сделать это с помощью afnetwroking

 -(void)saveServerData:(UIImage *)image{ NSData *imageToUpload = UIImageJPEGRepresentation(image, 1.0); if (imageToUpload) { NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys: GameId, @"gameid" , useremail, @"userid" , PartIndex, @"imageposition" , nil]; NSString *url=[NSString stringWithFormat:@"%@addplayerresponse",BASE_URL]; AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:url]]; NSLog(@"%@",parameters); NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:url parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { [formData appendPartWithFileData: imageToUpload name:@"image" fileName:[NSString stringWithFormat:@"%@_%@.jpeg",appDelegate.userid,appDelegate.onlineGameId] mimeType:@"image/jpeg"]; }]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { // NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil]; NSLog(@"Response:%@",parameters); //success } failure:^(AFHTTPRequestOperation *operation, NSError *error) { if([operation.response statusCode] == 403) { return; } NSLog(@"error: %@", [operation error]); }]; [operation start]; } } 

И я не думаю, что вы можете загрузить папку, либо вам нужно загрузить одно изображение за раз, либо вам нужно сделать zip папку и отправить ее, а в php вам придется распаковать ее после сохранения.

Вот мой пример кода

  NSURL *nsurl =[NSURL URLWithString:urlString]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:nsurl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; [request setURL:nsurl]; [request setHTTPMethod:@"POST"]; NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *body = [NSMutableData data]; //Image [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"%@\"\r\n",[fileName text]] 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 stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; // setting the body of the post to the reqeust [request setHTTPBody:body]; NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 

Вы должны использовать / вызывать API в рекурсивной функции, чтобы это сделать.

Серверный код

 //Create a folder named images in your server where you want to upload the image. // And Create a PHP file and use below code . <?php $uploaddir = 'images/'; $ran = rand () ; $file = basename($_FILES['userfile']['name']); $uploadfile = $uploaddir .$ran.$file; if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) { echo "www.host.com/.../images/{$uploadfile}"; } ?> 

Код приложения

  - (IBAction)uploadClicked:(id)sender { [self UploadTheImageNow:0]; } 

Приведенный ниже код предназначен для рекурсивной функции, которая будет продолжаться до тех пор, пока вся загрузка изображения не закончится.

 -(void)UploadTheImageNow:(NSInteger)count { // UIImage *updatedImage=[UIImage ImageNamed:@" Your Image name / you can get from array"]; UIImage *updatedImage=[UIImage ImageNamed:[yourArray ObjectAtIndex:ic]]; NSData *imageData = UIImageJPEGRepresentation(updatedImage, 90); NSString *urlString = @"your URL link"; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *body = [NSMutableData data]; [body appendData:[[NSString stringWithFormat:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="userfile"; filename="ipodfile.jpg"rn"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:imageData]]; [body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:body]; [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) { if ([(NSHTTPURLResponse *)response statusCode]==200) { id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil]; NSLog(@"Finished with jsonObject %@", jsonObject); count++; if(count<20) { [self UploadTheImageNow:count]; } else { // Finished Uploading all Images } } }]; }
