當從iPhone發佈到服務器時，圖像被損壞

這裏是我的代碼上傳圖像到php服務器，但圖像上傳爲服務器上的損壞的圖像。下面是我的代碼，請告訴我的問題..我嘗試了可可休息客戶端，圖像正在從它正確上傳。當從iPhone發佈到服務器時，圖像被損壞

NSString *filename = @"connect-blue.png"; 
    UIImage *image = [UIImage imageNamed:filename]; 
    NSMutableURLRequest * request= [[[NSMutableURLRequest alloc] init] autorelease]; 
    [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 *postbody = [NSMutableData data]; 
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"profile_image\"; filename=\"%@\"\r\n",filename] dataUsingEncoding:NSUTF8StringEncoding]]; 
    [postbody appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    [postbody appendData:[postString dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSData *imagedata = UIImageJPEGRepresentation(image,1.0f); 

    [postbody appendData:[NSData dataWithData:imagedata]]; 
    [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

PHP代碼是在這裏

if(!empty($_FILES)){ 
// 
    $imgname=$_FILES['image']['name']; 
     $a=pathinfo($imgname); 

    if(!empty($a['extension'])){ 
    $img_name=$a['filename']; 
    $img_ext=$a['extension']; 
} 

    else 

    { 

    $img_name=''; 

    $img_ext=''; 

    } 

    $img_pre=mktime(); 

    $image1=$img_pre."_".$imgname; 
    move_uploaded_file($_FILES['image']['tmp_name'], "uploads/images/" . $image1);
