Question

我严格遵循How can I upload a photo to a server with the iPhone?的答案。

以下部分是按下按钮时调用的部分。

NSLog(@"buttonPressed: %@", [ConnectServerTryViewController getPathForFile: @"myPic.png"]);
[[EPUploader alloc] initWithURL:[NSURL URLWithString:@"http://10.27.8.251/senior/uploader.php"]
                       filePath: [ConnectServerTryViewController getPathForFile: @"myPic.png"] 
                       delegate:self
                   doneSelector:@selector(onUploadDone:)
                  errorSelector:@selector(onUploadError:)];

这是我的ConnectServerTryViewController类的静态getPathForFile方法：

+ (NSString*) getPathForFile: (NSString*) st{
    NSString * path = [[NSBundle mainBundle] bundlePath];
    NSString * finalPath = [path stringByAppendingPathComponent: st];
    return finalPath;   
}

我非常确定我的php是正确的。我可以毫无问题地将图像从我的mac上传到我的服务器，但下面显示了XCode控制台的输出：

您是否知道这里可能存在哪些错误？

非常感谢。

Answer 1

onUploadError：是ConnectServerTryViewController上的无效选择器。如何定义onUploadError，它是否在ConnectServerTryViewController类中定义？

有人可以帮助我发现有关将图像从iPhone上传到服务器的错误吗？
