AFNetworking怎么设置上传进度条？

Question

查了一圈，查到了setuploadprogress这个方法，但是不知道怎么用。
补一下代码吧
AFHTTPRequestOperationManager*manager=[AFHTTPRequestOperationManagermanager];
[managerPOST:urlStrparameters:nilconstructingBodyWithBlock:^(idformData){
[formDataappendPartWithFileData:imgDataname:@"pic"fileName:fileNamemimeType:@"image/jpeg"];
}success:^(AFHTTPRequestOperation*operation,idresponseObject){
NSLog(@"success:%@",responseObject);
NSIntegerresult=[[responseObjectobjectForKey:@"result"]integerValue];
if(result==1){
successBlock(responseObject);
}else{
UIAlertView*alertView=[[UIAlertViewalloc]initWithTitle:nilmessage:@"出错了"delegate:nilcancelButtonTitle:@"ok"otherButtonTitles:nil,nil];
[alertViewshow];
}
}failure:^(AFHTTPRequestOperation*operation,NSError*error){
UIAlertView*alertView=[[UIAlertViewalloc]initWithTitle:nilmessage:[errorlocalizedDescription]delegate:nilcancelButtonTitle:@"ok"otherButtonTitles:nil,nil];
[alertViewshow];
failureBlock(error);
}];

Answer 1

-(void)setUploadProgressBlock:(void(^)(NSUIntegerbytesWritten,longlongtotalBytesWritten,longlongtotalBytesExpectedToWrite))block;在block里totalBytesWritten/totalBytesExpectedToWrite

Answer 2

AFHTTPRequestOperation*op=xxx;[self.uploadProgressViewsetProgressWithUploadProgressOfOperation:opanimated:YES];
