Objective-C服務器上的上傳圖像不完整

Question

我正在維護一些代碼，可通過Objective-C和php將照片從ipad上傳到apache2服務器。 在objective-c中，使用AFNetworking POST功能更新圖片。 圖片實際上已成功上傳，但是不完整。 這是我在服務器上得到的：

如您所見，它僅顯示屏幕截圖的左上部分。 Objective-C中的代碼類似於imagePickerController的代碼

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    LoginData * dataObject = [self dataObject];
    NSString *tempPath = [NSString stringWithFormat:@"upload-image.jpg"];
    NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:tempPath];

    UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage];
    NSData *imageData = UIImageJPEGRepresentation(img, 1);
    [imageData writeToFile:path atomically:YES];

    NSString *uploaddir = [NSString stringWithFormat:@"../exampledir/"];
    NSString *requestURL = [NSString stringWithFormat:@"http://%@/handle_upload.php", httpPath];
    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:path, @"newname",uploaddir, @"pathname", nil];
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager POST:requestURL parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"uploadedfile" fileName:path mimeType:@"image/jpeg"];
    } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        [[[UIAlertView alloc]
          initWithTitle:@"Message" message:@"Upload was successful" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]show];
        NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
        NSLog(@"%@", string);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error with upload : %@", error);
        [[[UIAlertView alloc]
          initWithTitle:@"Message" message:@"Upload was completed" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]show];
    }];
    [picker dismissViewControllerAnimated:YES completion:NULL];
}

文件“ handle_upload.php”如下：

<?php
require_once("validate.php");

/* This script uploads a file to a given directory with a given name
 * Parameters:
 * @pathname - the path of the directory the file will be uploaded to
 * @newname - the new name of the file
 * @uploadedfile - the file to be uploaded
 */

$target_path = $_POST['pathname'];
$new_name = $_POST['newname'];


$target_path = $target_path . basename($new_name);

if ($_FILES['uploadedfile']['error'] > 0) {
    echo "There was an error transferring the file" . PHP_EOL;
    echo "Error code: " . $_FILES['uploadedfile']['error'] . PHP_EOL;
}
if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file " . basename( $_FILES['uploadedfile']['name']) .
                     " has been uploaded";   // success is indicated by presence of string 'has been uploaded'
} else {
    echo "There was an error uploading the file, please try again!" . PHP_EOL;
    echo '$_POST[\'pathname\']: ' . $_POST['pathname'] . ' $_POST[\'newname\']: ' . $_POST['newname'] . PHP_EOL;
    echo '$target_path: ' . $target_path . PHP_EOL;

    echo "Upload: " . $_FILES["uploadedfile"]["name"] . PHP_EOL;
    echo "Type: " . $_FILES["uploadedfile"]["type"] . PHP_EOL;
    echo "Size: " . ($_FILES["uploadedfile"]["size"] / 1024) . PHP_EOL;
    echo "Stored in: " . $_FILES["uploadedfile"]["tmp_name"] . PHP_EOL;
}

?>

每個人都有遇到過這種問題嗎？ 我將不勝感激，甚至為解決該問題提供了一些指導。
