Question

我刚刚将我的应用更新为ios5，下面的代码（工作在4x中）现在无效我认为这是因为UUID，但我改变了，错误保持不变。我得到的错误如下。非常感谢任何帮助 - thx

我设置了一些断点并隔离了错误，我认为错误是使用localPutObjectRequest，但在查看该行后，错误消息对我没有意义。

- (void) updateLocation:(CLLocation*)loc
{
    [progressView setProgress:5];
    [[LocationManager sharedLocationManager] setDelegate:nil];

    uploadPath = [NSString stringWithFormat:@"%@/%@-%f.png", [[UIDevice currentDevice] uniqueIdentifier], [[UIDevice currentDevice] uniqueIdentifier], [[NSDate date] timeIntervalSince1970]];

    S3PutObjectRequest *localPutObjectRequest = [[[S3PutObjectRequest alloc] initWithKey:uploadPath inBucket:[NSString stringWithFormat:@"spotted-at"]] autorelease];


    localPutObjectRequest.data = UIImagePNGRepresentation([UIImage imageWithData:imageData]);
    [localPutObjectRequest setDelegate:self];

    [[Constants s3] putObject:localPutObjectRequest];

}

从您的帖子判断，错误在于

[[UIDevice currentDevice] uniqueIdentifier]

UIDevice uniqueIdentifier方法在iOS 5中已弃用，不应调用。从你的代码我真的不知道你究竟想要做什么，但这篇文章 UIDevice uniqueIdentifier Deprecated - What To Do Now?

应该有助于克服弃用的方法。您应该更改已弃用的呼叫，并使用上面帖子中列出的呼叫。这应该可以解决问题。
