iphone - 上传图片 iPhone

Question

我正在尝试使用 php 将 uiimage 从我的手机应用程序上传到服务器。但有些它不起作用。有人可以帮我吗？我的代码:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:url]];
            request.delegate = self;
            request.tag = 33;
            [request setPostValue:[NSString stringWithFormat:@"%@.png",responseString] forKey:@"name"];
            NSArray *sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
            NSString *docDirectory = [sysPaths objectAtIndex:0];
            NSString *filePath = [NSString stringWithFormat:@"%@/MyImage.png", docDirectory];
            [request setFile:filePath forKey:@"photo"];

            [request startAsynchronous];
            [url release];
            NSError *error = [request error];
            if (!error) {
                NSString *response = [request responseString];
                NSLog(@"aResponse:%@",response);

            }

if(move_uploaded_file($_FILES['photo']['tmp_name'],$target_path)) {
    echo "The file ". basename( $_FILES['photo']['tmp_name'])." has been uploaded";
} 
else {
    echo "There was an error uploading the file, please try again!";
}

在 ASI 请求文件中使用 nszombie 进行调试时出现以下错误

不要释放 URL:请求将异步运行，因此在您释放它时它还没有完成。
