iOS Amazon S3客户端-如何处理“请求超时”

Question

我收到很多这些崩溃报告：

Fatal Exception: AmazonClientException
Request timed out.

发生错误的代码行是这样的：

S3PutObjectResponse *response = [self.s3 putObject:putObjectRequest]; //ERROR HERE

if(response.error != nil)
        {
            NSLog(@"Amazon Client Error: %@", response.error);
        }


        if (response.exception) {
            if (theRequest.failureBlock) {
                theRequest.failureBlock([response description]);
            }
        }
        else if (scRequest.successBlock) {
            //success
        }

问题是发生超时，因此我没有机会处理任何错误或异常。

我在哪里可以放置代码来处理请求超时，以使应用程序不会崩溃？

仅当请求超时时才发生崩溃。

您正在调用的AmazonS3Client方法抛出一个Objective-C异常。 使用@try / @catch捕获它。
