如何在iphone中上传参数以及图像和音频

我不熟悉iPhone编程。有人能告诉我我上传了图像和音频以及这些参数吗

输入参数：

caption

，

user\u id

，

mobile\u tauky\u id

，

blauky\u id

，

image

，

音频

（

caption

和

blauky\u id

是可选的）

使用下面的代码我可以上传

图像

，同样我想先上传

标题

，

用户id

意味着一些整数值，例如：

3

，

手机id

还有一些整数值，例如：

5

，

blauky\id

也包括

2

，

图像

和

音频

我可以在哪里附加这些参数？首先，我想附加标题，然后是

用户id

，然后是

手机id

，

blauky id

，然后我必须附加

图像

和

音频

。任何人都可以告诉我如何在下面的代码中附加这些参数。我只能附加

图像

，但在此之前，我想附加标题、

用户id

、

手机id

NSString *urlString = @"http://182.73.152.59:82/php/tauky_services/codeigniter-restserver-master/index.php/api/uploadClass/uploadTauky/";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSLog(@"%@", request);

NSMutableData *body = [NSMutableData data];   

//Image
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"%@\"\r\n",imageData] 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]];
 [request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Response : %@",returnString);

if([returnString isEqualToString:@"Success ! The file has been uploaded"]) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Image Saved Successfully" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
    [alert show];
}
NSLog(@"Finish");

您可以逐个附加参数，如：-

NSURL *dataURL=[[NSURL alloc]initWithString:[NSString stringWithFormat:@"http://182.73.152.59:82/php/tauky_services/codeigniter-restserver-master/index.php/api/uploadClass/uploadTauky/"]];

NSMutableURLRequest *dataRqst = [NSMutableURLRequest requestWithURL:dataURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0];

[dataRqst setHTTPMethod:@"POST"];

NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo";
NSString *headerBoundary = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",stringBoundary];

[dataRqst addValue:headerBoundary forHTTPHeaderField:@"Content-Type"];

NSMutableData *postBody = [NSMutableData data];

// -------------------- ---- caption ---------------------------\\


[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];

使用appendData就像您完成其他操作一样。这里的值没有上载。我得到的响应是：satatus:failed应该是空的userid“NSString*caption=@“Aslam”；NSString*user_id=@“10”；NSString*mobile_tauky_id=@“2”；NSString*blauky_id=@“0”";那么它也不上传也给每个参数的类型每个参数的类型意味着什么？
