大佬教程收集整理的这篇文章主要介绍了iOS Amazon S3 SDK：发送到解除分配的实例的消息，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
*** -[S3PutObjectOperation_Internal respondsToSELEctor:]: message sent to deallocated instance 0x43c18fd0
我不太了解Zombies检查员的堆栈跟踪,我不确定这是否告诉我任何我可以解决的问题：

应用程序上传照片时会发生此错误. Photo对象使用并实现以下方法：
-(void)request:(Amazonservicerequest *)request didSendData:(NSInteger)bytesWritten @R_702_10586@lBytesWritten:(NSInteger)@R_702_10586@lBytesWritten @R_702_10586@lBytesExpectedToWrite:(NSInteger)@R_702_10586@lBytesExpectedToWrite { NSLog(@"didSendData called: %d - %d / %d",bytesWritten,@R_702_10586@lBytesWritten,@R_702_10586@lBytesExpectedToWritE); self.transferProgress += bytesWritten; float p = (float) self.transferProgress / self.uploadSize; self.uploadProgress = [NS@R_450_10793@er @R_450_10793@erWithFloat:p]; } -(void)request:(Amazonservicerequest *)request didCompleteWithResponse:(AmazonserviceResponse *)response { NSLog(@"didCompleteWithResponse called."); } -(void)request:(Amazonservicerequest *)request didFailWithError:(NSError *)error { NSLog(@"didFailWithError called: %@",error); }
我不想禁用所有重试,所以我通过强制不重试服务异常来修复此问题.您可以使用AmazonS3Client的子类来覆盖一个方法,如下所示：
- (BOOL)shouldRetry:(AmazonserviceResponse *)response exception:(NSException *)exception { // There is some kind of bug that is triggered on request retries when S3 requests // return an explicit service exception (e.g.,auth token expired). In these cases // we force no retry to avoid the bug. NSException *exceptionHolder = response.exception; if(exceptionHolder == nil) { exceptionHolder = exception; } if([exceptionHolder isKindOfClass:[AmazonserviceException class]]) { return NO; } return [super shouldRetry:response exception:exception]; }
