在Xcode和ios中上载图像问题

我正在使用以下代码，因为我是xcode新手，请告诉我如何发送带有数据的图像。数据正完美地发布到服务器。只需添加代码，即可将图像发送到服务器：

- (IBAction)senddatatophp:(id)sender {

    NSLog(@"Working insert button");

    NSString *did = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceID"];
    NSString *deviceTokenStr = [[[[did description]
                                  stringByReplacingOccurrencesOfString: @"<" withString: @""]
                                 stringByReplacingOccurrencesOfString: @">" withString: @""]
                                stringByReplacingOccurrencesOfString: @" " withString: @""];

    //NSLog(@"%@", deviceTokenStr);

    NSData *getimgdata1 = UIImageJPEGRepresentation(_frontimg.image, 1);
    NSLog(@"%@", getimgdata1);


    NSString *name=@"Admin";
    NSString *lastname=@"panel";

    NSString *tag       =   @"watchlist";
    NSString *gcmid     =   deviceTokenStr;
    NSString *brand     =   textbox1.text;
    NSString *model     =   textbox2.text;
    NSString *year      =   textbox3.text;
    NSString *condition =   textbox4.text;
    NSString *box       =   textbox5.text;
    NSString *warranty  =   textbox6.text;
    //NSString *front_img =   _path1;
    //NSString *back_img  =   _path2;
    //NSString *side_img  =   _path3;

    NSString *sendData = @"name=";
    sendData = [sendData stringByAppendingString:[NSString stringWithFormat:@"%@", name]];
    sendData = [sendData stringByAppendingString:@"&lastname="];

    sendData = [sendData stringByAppendingString:@"&back_img="];
    sendData = [sendData stringByAppendingString:[NSString stringWithFormat:@"%@", back_img]];
    sendData = [sendData stringByAppendingString:@"&side_img="];
    sendData = [sendData stringByAppendingString:[NSString stringWithFormat:@"%@", side_img]];
    */


    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.onlinestoresolution.net/demo/buymywatch/buymywatch/index.php"]];

    [request setValue:@"gzip" forHTTPHeaderField:@"Accept-Encoding"];

    _SendWatchId = stringReply;

    if (error)
    {
        NSLog(@"Error: %@", stringReply);

    }
    else

将此代码用于发送图像文件。在服务器上发布文本数据后，请写下此代码

 UIImage *img=self.imgView.image;
NSData *imageData = UIImagePNGRepresentation(img);
NSString *urlString = [NSString stringWithFormat:@"%@upload.php",@"http://localhost:8888/ImageUploadiOS/"];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];

NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadedfile\"; filename=\"test%d.png\"\r\n",self.fileNum] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[@"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(@"Image Return String: %@", returnString);
self.fileNum++;
UIAlertView *alertUpload=[[UIAlertView alloc] initWithTitle:@"DemoApp" message:@"Image Uploaded On Server" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alertUpload show];

下面是在服务器上扫描图像数据的php代码

    <?php
$uploaddir = 'uploads/';
$file = basename($_FILES['uploadedfile']['name']);
$uploadfile = $uploaddir . $file;

echo "file=".$file; //is empty, but shouldn't

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) {
    echo $file;
}
else {
    echo "error";
}
?>

一次处理多个图像的Php代码是

      <?php
$uploaddir = 'uploads/';
$file1 = basename($_FILES['uploadedfile1']['name']);
$uploadfile = $uploaddir . $file1;

echo "file=".$file1; //is empty, but shouldn't

if (move_uploaded_file($_FILES['uploadedfile1']['tmp_name'], $uploadfile))
{
    //echo $file;
    //echo 'Hello ' . htmlspecialchars($_POST["name"]) . '!';
    echo 'file1 moved';
}
else
{
    echo "error";
}



$file2 = basename($_FILES['uploadedfile2']['name']);
$uploadfile = $uploaddir . $file2;

echo "file=".$file2; //is empty, but shouldn't

if (move_uploaded_file($_FILES['uploadedfile2']['tmp_name'], $uploadfile))
{
    //echo $file;
    //echo 'Hello ' . htmlspecialchars($_POST["name"]) . '!';
    echo 'file2 moved';
}
else
{
    echo "error";
}

这些都没有任何意义，但如果您希望同时发送字符串数据和图像数据，则需要将数据附加在一起。为此，最简单的方法是使用可变版本的
NSData
：

NSData *input1;
NSData *input2;
NSMutableData *output;

output = [[NSMutableData alloc] initWithData:input1];
[output appendData:input2];

然后，
input1
是您的字符串数据，
input2
是您的图像数据（反之亦然），您的
output
是您在身体中使用的数据

您可能需要查看的第一件事是异步发送请求，因为您正在处理大量数据

// add image data
NSData *getimgdata1 = UIImageJPEGRepresentation(_frontimg.image, 1);
if (getimgdata1) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:getimgdata1];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}

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

请参阅此
您是否已传递NSData*getimgdata1？在您的请求中，我已传递img字节码服务器响应将被分配到数据中。而不是使用deleage方法接收响应数据。这给了我错误“使用未声明的标识符‘数据’”我已经修改了我的答案，重新检查plsThanks错误是删除只剩下一个错误是filenum。请告诉我filenum是什么类型的值，用于唯一的图像文件名。每次我们将图像从应用程序发布到服务器上。如test1.png、test2.png等。
// add image data
NSData *getimgdata1 = UIImageJPEGRepresentation(_frontimg.image, 1);
if (getimgdata1) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:getimgdata1];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}

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