当异常关闭时未调用iOS didFailWithError的AWS

Question

当我像这样设置我的S3时

@property (nonatomic, strong) S3TransferManager *tm;

.
.

[AmazonErrorHandler shouldNotThrowExceptions];
[AmazonLogger verboseLogging];
self.tm = [S3TransferManager new];
self.tm.s3 = self.s3;
self.tm.delegate = self;

然后使用

request = .......

S3TransferOperation * op = [self.tm download:request];

当我获取存在于我的S3帐户上的文件时，回调将被调用。

-(void)request:(AmazonServiceRequest *)request didCompleteWithResponse:(AmazonServiceResponse *)response

但是，当我试图获取不退出的文件时，回调不会被调用。

-(void)request:(AmazonServiceRequest *)request didFailWithError:(NSError *)error

如果我移除

// [AmazonErrorHandler shouldNotThrowExceptions];

然后我有了一个不同的问题，异常被抛出，但是尽管我有一个适当的“try.”catch块，但是应用程序崩溃了。

    @try {

        .
        .
        .
        S3TransferOperation * op = [self.tm download:request];

    } @catch (AmazonServiceException *exception) {

        NSLog(@"========================>[S3 Module] ERROR, Unable to download file : %@", exception.error);

        return NUMBOOL(NO);

    } @catch (NSException * exception) {

        NSLog(@"*************************[S3 Module] ERROR, Unable to download file : %@", exception);

        return NUMBOOL(NO);
    }

这是禁用异常抛出时的AWS详细日志。

正如你所看到的，我的回调不会被触发。是不是我做错了什么？或者这是AWS中的一个bug？
