在我的iOS应用中将记录上传到Parse.com

Question

代码如下：我试图保存记录，它是＆＃34;记录器＆＃34;在我的应用中，我这样定义了他，AVAudioRecorder *录音机;它的录音很好，一切都很好。当我点击按钮UPLOAD它卡住了并且在Parse.com中没有什么新东西，Parse与其他东西一起工作很好所以解析它不是问题.. 我需要知道的是如何上传记录以解析某人会看到它的目标。 非常感谢你们！

- (IBAction)uploadButton:(id)sender {
if (recorder == nil) {
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"An error occurred!"
                                                        message:@"Creat your record!"
                                                       delegate:self cancelButtonTitle:@"OK"         otherButtonTitles:nil];
    [alertView show];
}
else {
    [self uploadRec];
    [self.tabBarController setSelectedIndex:0];
}
}

- (void)uploadRec {
NSData *fileData;
NSString *fileName;
NSString *fileType;

if (recorder != nil) {
    fileData = recorder;
    fileName = @"record.m4a";
    fileType = @"record";
    }
else {
}

PFFile *file = [PFFile fileWithName:fileName data:fileData];
[file saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
    if (error) {

                                                            message:@"Please try sending your message again."
                                                           delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alertView show];
    }
    else {
        PFObject *rec = [PFObject objectWithClassName:@"Rec"];
        [rec setObject:file forKey:@"file"];

                                                                   delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
                [alertView show];
            }
            else {
                // Everything was successful!
                [self reset];
            }
        }];
    }
